How to read dynamically added texbox's value in gridview

I need to create dynamic form, which i will have to create the textbox, textarea,dropdown etc, based on the field type.
Now, I have successfully created this dynamic textbox etc using my rowdatabound.
My problem is I could not retrieve the textbox value entered when the save button is clicked.
My aspx file
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox runat="server" ID="selectProspect" Checked="true" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="FieldTitle" HeaderText="" />
<asp:BoundField DataField="FieldType" HeaderText="FieldType" />
<asp:TemplateField>
<ItemTemplate>
//DYNAMICALLY ADDING TEXTBOX
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="RightText" HeaderText="" />
<asp:BoundField DataField="TemplatesInfoCode" HeaderText="TemplatesInfoCode" ItemStyle-CssClass="hiddencol" />
</Columns>
</asp:GridView>
My code behind file
protected void Page_Load(object sender, EventArgs e)
{
GetTemplateComponent();
}
public void GetTemplateComponent()
{
StringBuilder sb;
DataSet ds;
sb = new StringBuilder();
sb.AppendLine("select * from template where tc='0002' order by Sequence");
ds = Conn.DataAdapter(CommandType.Text, sb.ToString());
gv.DataSource = ds;
gv.DataBind();
}
protected void gv_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string value = Convert.ToString(DataBinder.Eval(e.Row.DataItem, "FieldType"));
if (value == "Date" || value == "TextBox")
{
TextBox TextBox1 = new TextBox() { ID = "TextBox1", EnableViewState = false, CssClass = "form-control" };
e.Row.Cells[3].Controls.Add(TextBox1);
}
if (value == "TextArea")
{
TextBox DateTextBox = new TextBox() { EnableViewState = false, CssClass = "form-control", TextMode = TextBoxMode.MultiLine, Rows = 5, Columns = 50 };
e.Row.Cells[3].Controls.Add(DateTextBox);
}
if (value == "Content")
{
TextBox ContentAreaControl = new TextBox()
{
TextMode = TextBoxMode.MultiLine,
EnableViewState = false,
Columns = 10,
MaxLength = 150,
Height = 200,
CssClass = "Content-container",
};
e.Row.Cells[3].Controls.Add(ContentAreaControl);
}
}
}
protected void SaveTemplateDetails(object sender, EventArgs e)
{
foreach (GridViewRow row in gv.Rows)
{
FieldValue.Value = row.Cells[3].Text.ToString();
*//I DONT KNOW HOW TO READ THE VALUE*
}
}
I just want to know how is the proper way to read this dynamically created textbox
Thank you

Displays file icons in asp.net on GridView

I can't to display file icons according to file extensions in asp.net GridView.
The structure of GridView is nested

if (!String.IsNullOrEmpty(lnkDownload.Text))

Can you help me?

You have a Nested GridView Structure and gvOrders is your inner GridView. So, you've to get LinkButton from inner GridView's row as like:
protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
GridView gvOrders = (GridView)e.Row.FindControl("gvOrders");
foreach (GridViewRow row in gvOrders.Rows)
{
LinkButton lnkDownload = (LinkButton)row.FindControl("lnkDownload");
HiddenField hf = (HiddenField)row.FindControl("HiddenField1");
if (!String.IsNullOrEmpty(lnkDownload.Text))
{
//... some code
}
}
}
}

how to fill dropdown in telerik grid databound?

i have a telerik grid and use GridTemplateColumn as bellow
<telerik:GridTemplateColumn DataField="Status" ReadOnly="true" UniqueName="colStatus" HeaderText="Status">
<ItemTemplate>
<asp:Label ID="lblStatus" runat="server"></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="drpstatus" runat="server" />
</EditItemTemplate>
</telerik:GridTemplateColumn>
then i fill dropdown and label in ItemDataBound event :
protected void grdList_ItemDataBound(object sender, GridItemEventArgs e)
{
if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)
{
if (e.Item is GridEditableItem && e.Item.IsInEditMode)
{
GridEditableItem editItem = (GridEditableItem)e.Item;
var info = (ProductViewInfo)e.Item.DataItem;
DropDownList drpstatus = (DropDownList)editItem["colStatus"].FindControl("drpstatus");
var cntType = new ProductTypeController();
var lst = cntType.GetStatusList(PortalId, enumTypes.MainGroup);
drpstatus.DataSource = lst;
drpstatus.DataTextField = "Caption";
drpstatus.DataValueField = "StatusID";
drpstatus.DataBind();
drpstatus.SelectedValue = info.Status.ToString();
}
else
{
var item = e.Item as GridDataItem;
var info = (ProductViewInfo)item.DataItem;
Label lblStatus = (Label)item["colStatus"].FindControl("lblStatus");
lblStatus.Text = info.StatusCaption;
}
}
}
but my drop down does not fill! "e.Item.IsInEditMode" always returns false. should i add anything else in order to fill dropdown?

I guess the problem related to ReadOnly="true"
try to remove it

Add new record to Telerik RadGrid

I have the following Telerik RadGrid, which I'm using in C#:
<MasterTableView Width="100%" EditMode= "InPlace" ClientDataKeyNames="menuID" CommandItemDisplay= "Top">
<Columns>
<telerik:GridBoundColumn DataField="Name" HeaderText="Name" SortExpression="Name" UniqueName="Name"></telerik:GridBoundColumn>
<telerik:GridTemplateColumn UniqueName="Type" HeaderText="Type">
<ItemTemplate>
<asp:TextBox ID="Type" Text='<%# DataBinder.Eval(Container.DataItem, "Type") %>' runat="server"></asp:TextBox>
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn UniqueName="List" HeaderText="List">
<ItemTemplate>
<asp:CheckBox ID="List" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "List") %>' />
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn UniqueName="loadAtStart" HeaderText="loadAtStart">
<ItemTemplate>
<asp:CheckBox ID="loadAtStart" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "loadAtStart") %>' />
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
</Columns>
</MasterTableView>
The grid is populated with data, and working normally when editing the data.
But when I click on the Add New Record button provided by Telerik, then an empty row is added without any TextBox or CheckBox in the columns to edit in the new Row added. It's just an empty row. I presume that I have to create the controls dynamically in the called ItemDataBound event, but I didn't manage to find the actual code for this.
How do I solve this?

Please try with the below code snippet.

Hope this would help you :-)

I'm not really a fan of any of these solutions because they require the use of Session. Session has it's place but I believe it's used more as a crutch.
You're already sending the RadGrid information back to the server-side via ViewState due to the PostBack so why not use it's information instead of relying on an in-memory store.
Example of Adding and Removing an item from a Grid. Yes, it does require iterating items to rebuild a List but it's an alternative to Session so I believe it has merit.
protected void addValueToRecentTagList(string text)
{
List<string> items = new List<string>();
foreach(GridDataItem row in RadGridNewTags.Items)
items.Add(row["tag"].Text);
items.Add(text);
RadGridNewTags.DataSource = items;
RadGridNewTags.DataBind();
}
protected void removeValueFromRecentTagList(string text)
{
List<string> items = new List<string>();
bool rebind = false;
foreach (GridDataItem row in RadGridNewTags.Items)
{
if (row["tag"].Text == text)
rebind = true;
else
items.Add(row["tag"].Text);
}
if (rebind)
{
RadGridNewTags.DataSource = items;
RadGridNewTags.DataBind();
}
}

You have to insert a control in the EditItemTemplate to display in Edit or Insert mode.
Or you can add an InsertItem Template and place a control in there:
<telerik:GridTemplateColumn UniqueName="loadAtStart" HeaderText="loadAtStart">
<ItemTemplate>
<asp:CheckBox ID="loadAtStart" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "loadAtStart") %>' />
</ItemTemplate>
<EditItemTemplate>
<asp:CheckBox ID="cbxEditLoadAtStart" runat="server" Checked='<%# Bind("loadAtStart") %>' />
</EditItemTemplate>
<InsertItemTemplate>
<asp:CheckBox ID="cbxInsertLoadAtStart" runat="server" />
</InsertItemTemplate>
</telerik:GridTemplateColumn>

Any ideas?
Thanks,

Try using Button editbtn = (Button)sender; Rather than Button EditButton = (Button)gvGroupMaster.Rows[(((GridViewRow)(((Button)(sender)).Parent.BindingContainer))).RowIndex].FindControl("btnEdit");
