I am trying to get all site-collections under the root site and display them using SPGridView. In the SPGridView I am using HyperlinkField to display the name, url and created for each site.
My problem is that I cannot attach the url of the site to HyperlinkField. Any idea how this can be done in code?

dataSource.Columns.Add("Created");
dataSource.Columns.Add("Url");
SPWebApplication webApplication = SPContext.Current.Site.WebApplication;
SPSiteCollection siteCollections = webApplication.Sites;
SPSite currentSite = SPContext.Current.Site;
foreach (SPSite siteCollection in siteCollections)
{
dataSource.Rows.Add(siteCollection.RootWeb.Title, siteCollection.RootWeb.Created, siteCollection.RootWeb.Url);
}
return dataSource;

You should use the HyperLinkField.DataNavigateUrlFields Property instead:
HyperLinkField hyplink = new HyperLinkField();
hyplink.DataTextField = "Name";
hyplink.DataNavigateUrlFields = new string[] { "Url" };
hyplink.SortExpression = "Name";
hyplink.HeaderText = "Workspaces";
grid.Columns.Add(hyplink);
The HyperLinkField.NavigateUrl Property is used to render static urls:
Use the NavigateUrl property to specify the URL to navigate to when a hyperlink in a HyperLinkField object is clicked. When this property is set, each hyperlink shares the same navigation URL.

I am working on C#. I use this code copied from the link below to show multi-layered column headers to DataGridView.
DataGridView – Stacked Header
I succeeded to show multi-layered col header itself, but I can't add rows under the column headers. Instead, I got the added rows to be appeared in the col headers that are automatically created besides the multi-layered column headers.
private void Form1_Load(object sender, EventArgs e)
{
DataGridView dgv = dataGridView_syukei;
StackedHeaderDecorator objREnderer = new StackedHeaderDecorator(dgv);
dgv.Columns.Add("Name", "a.Name");
dgv.Columns.Add("1", "a.Id");
List<TestClass> testClasses = new List<TestClass>();
TestClass testClass1 = new TestClass();
testClass1.Id = 1;
testClass1.Name = "John";
TestClass testClass2 = new TestClass();
testClass2.Id = 2;
testClass2.Name = "Mike";
testClasses.Add(testClass1);
testClasses.Add(testClass2);
dgv.DataSource = testClasses;
}
class TestClass
{
public string Name { get; set; }
public int Id { get; set; }
}
Adding AutoGenerateColumns = false and DataPropertyName soloved this problem.
private void Form1_Load(object sender, EventArgs e)
{
DataGridView dgv = dataGridView_syukei;
dgv.AutoGenerateColumns = false;
StackedHeaderDecorator objREnderer = new StackedHeaderDecorator(dgv);
DataGridViewColumn dataGridViewColumn_Name = new DataGridViewColumn();
dataGridViewColumn_Name.HeaderText = "a.Name";
dataGridViewColumn_Name.DataPropertyName = "Name";
dataGridViewColumn_Name.CellTemplate = new DataGridViewTextBoxCell();
dgv.Columns.Add(dataGridViewColumn_Name);
DataGridViewColumn dataGridViewColumn_Id = new DataGridViewColumn();
dataGridViewColumn_Id.HeaderText = "a.Id";
dataGridViewColumn_Id.DataPropertyName = "Id";
dataGridViewColumn_Id.CellTemplate = new DataGridViewTextBoxCell();
dgv.Columns.Add(dataGridViewColumn_Id);
List<TestClass> testClasses = new List<TestClass>();
TestClass testClass1 = new TestClass();
testClass1.Id = 1;
testClass1.Name = "John";
TestClass testClass2 = new TestClass();
testClass2.Id = 2;
testClass2.Name = "Mike";
testClasses.Add(testClass1);
testClasses.Add(testClass2);
dgv.DataSource = testClasses;

Hi,
I am creating a web page in asp.net based on data from a database. This should result in a number of tab pages with card views on each tab with 5 columns and a maximum of 20 rows. The tab pages are working, the rows are working but the columns will not change from the default 3 columns.
I have tried setting the columnCount property at different stages, post and pre databinding. This getting frustrating.
I am having problems with setting a card views column count programmatically. I am setting it, have tried to set it in different places but it always goes to the default 3 columns :(
I am using C# in Visual studio 2017.
Here is the code I am using:
SqlDataSource sds = new SqlDataSource();
public string fName;
protected void Page_Load(object sender, EventArgs e)
{
string fid = Request.QueryString["FID"];
sds.ConnectionString = ConfigurationManager.ConnectionStrings["DataBaseConnection"].ToString();
sds.SelectCommand = "select name from [flashboard] where flashboardid = " + fid;
DataView fDet = (DataView)sds.Select(DataSourceSelectArguments.Empty);
fName = fDet.Table.Rows[0]["name"].ToString();
TitleLink.InnerHtml = fName;
sds.SelectCommand = "SELECT flashboardtabid, name FROM [FlashboardTab] WHERE flashboardid = " + fid+" order by SeqNo";
DataView fTab = (DataView)sds.Select(DataSourceSelectArguments.Empty);
TabPage tabDet;
ASPxPageControl tpc = ASPxPageControl1;
ASPxCardView cardGrp;
CardViewTextColumn cName;
CardViewHyperLinkColumn cEvidence;
foreach (DataRow tab in fTab.Table.Rows)
{
tabDet = new TabPage();
tabDet.Text = tab["name"].ToString();
tabDet.Name = "Tab"+tab["flashboardtabid"].ToString();
tabDet.ActiveTabStyle.Width = Unit.Percentage( 80);
cardGrp = new ASPxCardView();
cardGrp.ID = "CardGroup" + tab["flashboardtabid"].ToString() ;
tabDet.Controls.Add(cardGrp);
tpc.TabPages.Add(tabDet);
cardGrp.AutoGenerateColumns = false;
ASPxCardViewPagerSettings cvps = new ASPxCardViewPagerSettings(cardGrp);
cardGrp.EnableTheming = true;
cardGrp.Theme = "SoftOrange";
cvps.Visible = false;
cvps.SettingsTableLayout.ColumnCount = 5;
cvps.SettingsTableLayout.RowsPerPage = 20;
cardGrp.DataSource = GetData("SELECT cardid, Description, EvidencePage, SmartViewid FROM [flashboardcard] WHERE flashboardtabid = "+tab["flashboardtabid"] + " order by SeqNo");
cardGrp.Attributes.Add("Width", "80%");
cardGrp.Attributes.Add("style", "margin:auto");
cName = new CardViewTextColumn();
cName.Name = "Description";
cName.FieldName = "Description";
cEvidence = new CardViewHyperLinkColumn();
cEvidence.Name = "EvidencePage";
cEvidence.FieldName = "EvidencePage";
cEvidence.PropertiesHyperLinkEdit.Text = "Evidence";
cardGrp.Columns.Add(cName);
cardGrp.Columns.Add(cEvidence);
var layoutitem1 = new CardViewColumnLayoutItem(); // cardGrp.CardLayoutProperties.FindColumnItem("EvidencePage");
layoutitem1.ColumnName = "EvidencePage";
layoutitem1.ShowCaption = DevExpress.Utils.DefaultBoolean.False;
layoutitem1.HorizontalAlign = FormLayoutHorizontalAlign.Center;
var layoutitem2 = new CardViewColumnLayoutItem();
layoutitem2.ColumnName = "Description";
layoutitem2.ShowCaption = DevExpress.Utils.DefaultBoolean.False;
layoutitem2.HorizontalAlign = FormLayoutHorizontalAlign.Center;
layoutitem2.ParentContainerStyle.Font.Bold = true;
layoutitem2.ParentContainerStyle.Font.Size = FontUnit.Medium;
cardGrp.CardLayoutProperties.Items.Add(layoutitem2);
cardGrp.CardLayoutProperties.Items.Add(layoutitem1);
cardGrp.DataBind();
}
}
DataView GetData(String queryString)
{
DataView ds = new DataView();
sds.SelectCommand = queryString;
ds = (DataView)sds.Select(DataSourceSelectArguments.Empty);
return ds;
}
To resolve this issue with ColumnCount, I recommend you define it directly in the control's SettingsPager.SettingsTableLayout.ColumnCount property instead of specifying it in a new ASPxCardViewPagerSettings instance:
cardGrp.SettingsPager.SettingsTableLayout.ColumnCount = 5;
cardGrp.SettingsPager.SettingsTableLayout.RowsPerPage = 20;
I'm using a (Telerik) RadListView (Telerik.WinControls.UI.RadListView()) in my project.
The listview has a few columns:
public MainForm()
{
Telerik.WinControls.UI.ListViewDetailColumn newColumn;
InitializeComponent();
newColumn = new ListViewDetailColumn("ID", "ID");
newColumn.Width = 250;
newColumn.Visible = false;
this.MyListView.Columns.Add(newColumn);
newColumn = new ListViewDetailColumn("Name", "Name");
newColumn.Width = 250;
newColumn.Visible = true;
this.MyListView.Columns.Add(newColumn);
newColumn = new ListViewDetailColumn("Description", "Description");
newColumn.Width = 250;
newColumn.Visible = true;
this.MyListView.Columns.Add(newColumn);
newColumn = new ListViewDetailColumn("Costs", "Costs");
newColumn.Width = 250;
newColumn.Visible = true;
this.MyListView.Columns.Add(newColumn);
I'm populating the listview manually by adding ListViewDataItems to it:
foreach (Data.Tablename listEntry in ListOfTableEntries)
{
ListViewDataItem newRow = new ListViewDataItem(listEntry.Id, new string[]{ listEntry.Name, listEntry.Description, listEntry.Costs});
this.MyListView.Items.Add(newRow);
}
So far so good. What I did not find out though is how I can format specific columns that are making up the added row. For example: Right-align the costs.
How can I do that (without also right-aligning all other columns)?
Thanks
Try something along these lines:
private void radListView1_CellFormatting(object sender, ListViewCellFormattingEventArgs e)
{
if ((e.CellElement).Data.HeaderText == "ID")
{
if ((e.CellElement is DetailListViewDataCellElement))
{
e.CellElement.TextAlignment = ContentAlignment.TopRight;
}
}
if ((e.CellElement).Data.HeaderText == "Name")
{
if ((e.CellElement is DetailListViewDataCellElement))
{
e.CellElement.TextAlignment = ContentAlignment.MiddleCenter;
}
//end so on
}
}
I am new to Ajax. I am implementing a cascading dropdown in a telerik RadGrid.
I am adding the dropdownList and CascadingDropDown as follows:
DropDownList droplist = new DropDownList();
droplist.ID = "DropDownListOrderTask";
droplist.AutoPostBack = true;
item["OrderTask"].Controls.Add(droplist);
CascadingDropDown ccdOrderTask = new CascadingDropDown();
ccdOrderTask.ID = "ccdOrderTask";
ccdOrderTask.Category = "OrderTask";
ccdOrderTask.TargetControlID = "DropDownListOrderTask";
ccdOrderTask.PromptText = "Select Order Task";
ccdOrderTask.LoadingText = "Loading OrderTask";
ccdOrderTask.ServiceMethod = "BindOrderTask";
ccdOrderTask.ServicePath = "ajaxservice.asmx";
TextBox txt = (TextBox)item["TaskOwner"].Controls[0];
txt.Visible = false;
droplist = new DropDownList();
droplist.ID = "DropDownListTaskOwner";
item["TaskOwner"].Controls.Add(droplist);
CascadingDropDown ccdTaskOwner = new CascadingDropDown();
ccdTaskOwner.ID = "ccdTaskOwner";
ccdTaskOwner.Category = "TaskOwner";
ccdTaskOwner.ParentControlID = "DropDownListOrderTask";
ccdTaskOwner.TargetControlID = "DropDownListTaskOwner";
ccdTaskOwner.PromptText = "Select Task Owner";
ccdTaskOwner.LoadingText = "Loading Task Owner";
ccdTaskOwner.ServiceMethod = "BindTaskOwner";
ccdTaskOwner.ServicePath = "ajaxservice.asmx";
On the PreRender I have the following:
protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
var ajaxManager = RadAjaxManager.GetCurrent(Page);
if(ajaxManager != null)
ajaxManager.AjaxSettings.AddAjaxSetting(this._UpdatePanel, this._RadGrid1, this._RadLoadingPanel);
}
In the ajaxservice.asmx I have the following:
[WebMethod]
public CascadingDropDownNameValue[] BindOrderTask(string knownCategoryValues, string category)
{
OrderRequestTaskTypeTable _orderRequestTaskTypeTable = new OrderRequestTaskType_List().ExecuteTypedDataTable();
List<CascadingDropDownNameValue> orderTaskDetails = new List<CascadingDropDownNameValue>();
foreach(DataRow dtRow in _orderRequestTaskTypeTable.Rows)
{
String orderTaskId = dtRow["OrderRequestTaskTypeId"].ToString();
String orderTaskName = dtRow["DescriptionTaskType"].ToString();
orderTaskDetails.Add(new CascadingDropDownNameValue(orderTaskId, orderTaskName));
}
return orderTaskDetails.ToArray();
}
The first dropDown, DropDownListOrderTask contains no values. On debugging through Firebug it says: ReferenceError: BindOrderTask is not defined
I am sure I am missing something but not sure what. Please help me.
I have created a composite control that changes the controls in it based on the value of one of it's properties called "Type".
The intent is that once this "Type" property is set, it is not changed again for the life of the control, so the controls rendered as a result of the value of the "Type" property should not change.
I have overridden the LoadViewState and SaveViewState methods as recommended on by many internet posts, but I am still getting an error about "Failed to Load ViewState". The control will render appropriately on the first load, but once any postback is made, it generates the "Failed to Load ViewState" error.
Here is part of the code for the composite control:

Here is the code on the aspx page I am using to test the control:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
</div>
</form>
</body>
</html>
And the codebehind:
public partial class test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
CustomWebControls.SearchGrid<AccountCriteria> myAppFuncGrid = new MyCompany.DCO.MyProject.CustomWebControls.SearchGrid<AccountCriteria>();
myAppFuncGrid.Type = MyCompany.DCO.MyProject.CustomWebControls.SearchGridType.Account;
myAppFuncGrid.SelectionType = MyCompany.DCO.Library.WebControls.MyCompanygridviewSelectionType.Multiple;
myAppFuncGrid.PageSize = 3;
PlaceHolder1.Controls.Add(myAppFuncGrid);
}
}
I've tried only putting the control in if (!Page.IsPostBack) as well, but then it just doesn't even display the control at all on Postback. What am I doing wrong?
UPDATE:
So I added this to the composite control:
protected override void OnInit(EventArgs e)
{
this.CreateChildControls(); base.OnInit(e);
}
And now I no longer get the "failed to load viewstate" error, but it seems that the viewstate of the child controls is not saved across postbacks. One of the controls in my composite control is a gridview with paging enabled and when clicking on next page it will go to page two, but never to page 3 or 4 or so on. But it will go to "last page", "first page" without a problem. But Next Page and Previous Page do no work correctly, but it doesn't throw an error either. Ideas?
When adding your control dynamically to your page, try overriding OnInit or CreateChildControls and doing it in there.
Viewstate is loaded in the pre-load stage and therefore it cannot load viewstate for your controls as they dont yet exist...
