Find Control in code behind

[Saravanan]

I have a radCombobox inside the itemTemplate of RadGrid. I want to bind the radcombobox in the CodeBehind . so I tried using the following Code

Protected

 

Sub RadGrid1_EditCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.EditCommand

 

If e.Item.ItemType = GridItemType.AlternatingItem Or e.Item.ItemType = GridItemType.Item Then  

 

Dim item As Telerik.Web.UI.GridDataItem

item = e.Item

 

Dim radCombo As RadComboBox

radCombo = item(

"DropdownColumn").FindControl("radCombo")

 

 

 

radCombo.DataSource = objDetailDal.GetAccSAPDetails(objDetailInfo).Tables(0)

radCombo.DataBind()

End If  

 

End Sub 

 

< 

telerik:GridTemplateColumn HeaderText="Sap material Item " UniqueName="DropdownColumn" >

 

<ItemTemplate>

 

<asp:Label ID="lblItemNo" Width="150px" runat="server" CssClass="label" Text='<%# DataBinder.Eval (Container.DataItem, "ITEM") %>'></asp:Label>   

 

 

</ItemTemplate>

 

<EditItemTemplate>

 

 

<telerik:RadComboBox ID="radCombo" runat ="server" />
</EditItemTemplate>

 

 

 

 

 

 

</telerik:GridTemplateColumn>
But the Find Control method returns null values.

Kindly help me

Hello Raghuraman,

You can bind the RadComboBox in ItemDataBopound event of grid as shown below.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if ((e.Item is GridEditFormItem) && (e.Item.IsInEditMode))
    {
        GridEditFormItem insertItem = (GridEditFormItem)e.Item;
        RadComboBox combo = (RadComboBox)insertItem.FindControl("ddlPeatBU");
        // Now bind the combo
        combo.DataSourceID = "SqlDataSource1";
        combo.DataTextField = "CustomerID";
        combo.DataValueField = "CustomerID";
        combo.DataBind();
    }
}

Thanks Shinu.

I tried your set of code but of no use.
i have used AllowAutomaticUpdates="True" property.
So when i click 'edit' it goes to Radgrid1_Itemdatabound event but the condition
If (TypeOf e.Item Is GridEditFormItem) AndAlso (e.Item.IsInEditMode) Then

is always false

Please help me.

Hello Raghuraman,

Try with this check instead:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
    {
        GridEditFormItem insertItem = (GridEditableItem)e.Item;
        RadComboBox combo = (RadComboBox)insertItem.FindControl("ddlPeatBU");
        // Now bind the combo
        combo.DataSourceID = "SqlDataSource1";
        combo.DataTextField = "CustomerID";
        combo.DataValueField = "CustomerID";
        combo.DataBind();
    }
}

All the best,
