How to find a textbox control when the PreRender event is occured??

[Brew Hutch]

I have a textbox control inside the FilterTemplate as shown below:

<telerik:GridTemplateColumn UniqueName="firstname" >
    <ItemTemplate>
        ...
    </ItemTemplate>
    <FilterTemplate>
        <asp:textbox runat="server" id="txtBox1" text=""/>
    </FilterTemplate>
</telerik:GridTemplateColumn>

How can I get the textbox control when the RadGrid PreRender event is occurred?

Thanks

Hello Brew,

You can try the following code snippet in PreRender event to access the TextBox control inside FilterTemplate.

C#:

 protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        GridFilteringItem filterItem = (GridFilteringItem)RadGrid1.MasterTableView.GetItems(GridItemType.FilteringItem)[0];
        TextBox txtBox = (TextBox)filterItem.FindControl("txtBox1");
    }

Thanks,
Princy.

Is there a way to access the controll in FilterTemplate before any items in RadGrid are created?

Hello Dariusz,

Try the following code snippet in ItemCreated event.
C#:

protected void Grid_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
 {
    if (e.Item is GridFilteringItem)
    {
    GridFilteringItem item = (GridFilteringItem)e.Item;
    TextBox txt = (TextBox)item.FindControl("TextBox1");
  }
}

Thanks,
Shinu.
