Sir,
I want to have an insert link functionality to insert rows into gridview As we have auto generate edit and delete in gridview in asp.net,. how to do it?can u also provide me the links.
Hope i have understood your question and this solution might help you..
Solution:
<asp:GridView ID="GridView1" runat="server" AllowPaging="true" AllowSorting="true"
AutoGenerateColumns="False" PageSize="2" AutoGenerateDeleteButton="true" AutoGenerateEditButton="true"
DataKeyNames="theID" DataSourceID="SqlDataSource1" >
<PagerSettings Mode=NumericFirstLast />
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="Default2.aspx">HyperLink</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="theID" HeaderText="ID" ReadOnly="true" SortExpression="theID" />
<asp:BoundField DataField="theName" HeaderText="Name" SortExpression="theName" />
</Columns>
Use databinding to insert the row in theposition you want and after bind it to control, if you're talking about WindowsForms.
If youare talking about WPF, do the same :)
If you use ASP.NET insert the row into the binded data and "rebind" it.

I new to telerik and fighting my way up the learning curve.
I have a RadGrid that I'm populating with a linq query. I'm using a
GridTemplateColumn with a ComboBox for new and edit of one of the fields. The problem is the ComboBox doesn't show on the insert or edit screen. The fields set as GridDropDownColumn do show on the insert or edit. I need GridTemplateColumn solution because I need to run some code once the dropdown list has been selected.
What am I missing here? I'm trying to work from a Telerik example. It's the Release field that is giving me the problem.

I think your having trouble with the ComboBox because you have EnableLoadOnDemand=true but you have not subscribed to the ItemsRequested event. See Load On Demand Overview for details.
Since you mention your new to the controls, you might want to get the ComboBox LoadOnDemand working outside of the grid first.
Try removing the telerik namespace/prefix from the EditItemTemplate declaration:
Change this:
<telerik:EditItemTemplate>
<%-- RadComboBox --%>
</telerik:EditItemTemplate>
To this:
<EditItemTemplate>
<%-- RadComboBox --%>
</EditItemTemplate>
Also, please share with us which documentation were you following so that we can double check and report the documentation error.
I have a gridview on my web page.
I am able to populate the Grid using C# in the behind code.
Here is a sample screen of 2 columns and 2 rows:
What I don't understand is why there Gridlines are not showing on the rows of data when I have it set on the gridview properties to show "both".
<asp:GridView id="gvappts"
runat="server"
AllowPaging="True"
AllowSorting="True"
AutoGenerateColumns="False"
BorderColor="#EFE6F7"
ForeColor="#003399"
Width="100%"
Font-Size="Small"
GridLines="Both"
BorderStyle="Solid"
BorderWidth="1px"
CellPadding="3">
<Columns>
<asp:BoundField DataField="apptid" HeaderText="Appt #" />
<asp:BoundField DataField="name" HeaderText="Name" />
</Columns>
</asp:GridView>
What am I missing?
Please try the below code to your row border..
<RowStyle HorizontalAlign="Center" BackColor="White" BorderColor="#0000CC"
BorderStyle="Solid" BorderWidth="2px"/>
And also try the same to columns.
All of the comments on this post are correct to some extent which is, you mention that the issue must rely in the styles, after going line by line in my style sheets I found the culprit style and was able to get the grid-lines to show.
I have LinqDataSource that being attached to GridView In Asp.net web application.
<asp:LinqDataSource ID="LinqDataSource1" runat="server" ContextTypeName="DataClassesDataContext" OnInit="LinqDataSource1_Init"
EnableDelete="True"
EntityTypeName="Id" TableName="CompanysCourses"
OnDeleting="Course_Deleting" OnDeleted="Course_Deleted">
</asp:LinqDataSource>
Within OnInit event I have modified the select and where properties like that
this.LinqDataSource1.Where = "CompanyId == " + UserManager.CompanyId;
this.LinqDataSource1.Select= "Course";
I am selecting table named CompanysCourses and after that filter the result and select specific courses based on company's ID
And this is my grid view
<asp:GridView ID="grdVwCourses" runat="server"
AllowPaging="True" AllowSorting="True"
AutoGenerateColumns="False"
DataKeyNames="Id" DataSourceID="LinqDataSource1"
OnSelectedIndexChanged="grdVwCourses_SelectedIndexChanged"
CssClass="table table-responsive"
PageSize="10" GridLines="Horizontal"
meta:resourcekey="GridView1Resource1">
<EmptyDataTemplate>
<asp:Label runat="server" ID="NotFoundLabel" Text="" meta:resourcekey="NotFoundLabelResource1"></asp:Label>
</EmptyDataTemplate>
<Columns>
<asp:TemplateField HeaderText="#" meta:resourcekey="HeaderId">
<ItemTemplate>
<%# Container.DataItemIndex + 1 %>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Id" Visible="false"/>
<asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" meta:resourcekey="BoundFieldResource1" />
<asp:BoundField DataField="EnglishName" HeaderText="EnglishName" SortExpression="EnglishName" meta:resourcekey="BoundFieldResource2" />
<asp:BoundField DataField="CreatedDate" HeaderText="CreatedDate" SortExpression="CreatedDate" meta:resourcekey="BoundFieldResource3" />
<asp:TemplateField meta:resourcekey="TemplateFieldResource1">
<ItemTemplate>
<asp:HyperLink ID="userLink" runat="server" NavigateUrl='<%# GetCategoriesLink(Eval("Id")) %>' Text="Categories" meta:resourcekey="userLinkResource1" />
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField ShowSelectButton="True" ShowDeleteButton="True" meta:resourcekey="CommandFieldResource1" />
</Columns>
</asp:GridView>
I have in the grid view enabled deleting but when click delete I got this exception
LinqDataSource 'LinqDataSource1' does not support the Select property
when the Delete, Insert or Update operations are enabled.
I have override On_Deleting event like that to show confirmation dialog
protected void Course_Deleting(object sender, LinqDataSourceDeleteEventArgs e)
{
e.Cancel = true
this.panMessage.Visible = true;
int id = ((Course)e.OriginalObject).Id;
ViewState["DeleteObject"] = id;
}
I wonder what is the reason of this problem.
Edit
The question referred to as duplicate to mine doesn't have the answer that I seek, also the details are different.
I came today to the same issue on some legacy project, as the error showing this widget doesn't support deleting when you use SELECT statement.
so the solution is to remove your select statement from this datasource, ie remove this line:
this.LinqDataSource1.Select= "Course";
then on the gridview change DataKeyNames to your table Id name and also change the navigation property to access the fields, for example Course.Id, Course.Name etc for each columns in the fields.
the last thing is to cast to the main table and use the any field to access the Id of that table child value.
int id = ((Course)e.OriginalObject).Id;
I need to develop such a program in which the GridView's rows should be decided at run time.
i.e. I have a table in database called dealer capacity.
Dealer_ID Capacity
D0001 5
Now when the Dealer D00001 is selected from combo box the number of rows in grid view should be 5. I want to use the template field also.
My code for GridView is:
<asp:GridView ID="grdlicence" runat="server" DataKeyNames="Version_id" GridLines="None" BorderStyle="Solid" AutoGenerateColumns="false" AllowSorting="true"
CssClass="mGrid table"
PagerStyle-CssClass="pgr"
AlternatingRowStyle-CssClass="alt" >
<Columns>
<asp:BoundField DataField="Version_name" ItemStyle-CssClass="uppercase" ItemStyle-Width="150px" HeaderText="Version" HeaderStyle-HorizontalAlign="Left" />
<asp:BoundField DataField="Version_id" Visible="false" HeaderText="Version" HeaderStyle-HorizontalAlign="Left" />
<asp:TemplateField HeaderText="Price">
<ItemTemplate>
<center><asp:TextBox ID="txtprice" CssClass="alignments TextStyle" MaxLength="5" runat="server" ></asp:TextBox></center>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Licence Id">
<ItemTemplate>
<center><asp:TextBox ID="txtlicenceid" CssClass="alignments uppercase" runat="server" ></asp:TextBox></center>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Purchase Date">
<ItemTemplate>
<center><asp:TextBox ID="txtpurchasedate" onfocus="showCalendarControl(this);" CssClass="alignments TextStyle" runat="server"></asp:TextBox></center>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Expiry Date">
<ItemTemplate>
<center><asp:TextBox ID="txtexpirydate" onfocus="showCalendarControl(this);" CssClass="alignments TextStyle" runat="server"></asp:TextBox></center>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Upload File">
<ItemTemplate>
<center><asp:FileUpload ID="fileUpload" runat="server" /></center>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
You need to define PageSize for your GridView and remember to set AllowPaging to true for the GridView
GridView.PageSize Property
Gets or sets the number of records to display on a page in a GridView
control.
The default is 10.
You may see this article: GridView Paging Sample in ASP.NET
You can use the linq Take() and pass the number as parameter.
Updated according to the comment, use following code.
grdlicence.DataSourse= ds.Take(5);
grdlicence.DataBind();
I have a list of objects called Activity and I want to display the date, type and notes for each and every one of these activities. This is the code I'm using.
<asp:GridView ID="gvTable" runat="server" AllowSorting="true" ShowHeader="true">
<Columns>
<asp:BoundField DataField="ActivityDate" HeaderText="Date"
HeaderStyle-CssClass="date" />
<asp:BoundField DataField="ActivityType" HeaderText="Type" />
<asp:BoundField DataField="ActivityNotes" HeaderText="Notes" />
</Columns>
<PagerSettings Position="Bottom" Mode="NextPrevious" PageButtonCount="5"
PreviousPageText="Older activities" NextPageText="Newer activities" />
</asp:GridView>
However, all of the attributes of each object is displayed in the header. How can I force it to display only the columns that I want to use?
gvTable.AutoGenerateColumns = false
or
<asp:GridView ID="gvTable" runat="server" AutoGenerateColumns="False" AllowSorting="true" ShowHeader="true">
should do the trick.
Set the attribute on your gridview:
AutoGenerateColumns="false"
You need to set the AutoGenerateColumns property on the grid to false.
Have you tried AutoGenerateColumns="false" in the gridview?
