How to findcontrol in EditCommand event.

[Durga]

Hello,

I have a requirement like this,

I have a radGrid with a 2 columns.

Column 1 is a template column with
ItemTemplate as  asp:Linkbutton CommandName="Edit"and
EditItemTemplate as RadTextBox
<asp:ImageButton ID="btnQUpdate" CommandName="Update"
<asp:ImageButton ID="btnQCancel" CommandName="Cancel"

Column 2 is GridTemplateColumn with CommandName="Delete"

On click of the Linkbutton column row text, the grid row is setting in to edit mode and textbox is appearing with update and cancel buttons.
What I need here is,
1. I need to set the focus in that text box and select the current text in that box. so that user will be ready to update the text. ( so that setting focus and highlighting text events can be avoided)
2. On press Enter on that textbox the "Update" button click event should invoke.

I am really glad if some body help me to achieve this functionality

Thanks,
Durga

Hello Durga,

You can try out the following code to set the focus on the RadTextBox and select the text in the TextBox on focus.

aspx:

 <telerik:GridTemplateColumn UniqueName="TemplateColumn">
        <ItemTemplate>
            <asp:LinkButton ID="LinkButton1" CommandName="Edit" runat="server" >Edit</asp:LinkButton>
        </ItemTemplate>
        <EditItemTemplate>
            <telerik:RadTextBox ID="RadTextBox1" Text='<%#Bind("FirstName")%>'  runat="server">
            </telerik:RadTextBox>
            <asp:Button ID="Button1" runat="server" CommandName="Update" Text="Update"/>
            <asp:Button ID="Button2" runat="server" CommandName="Cancel" Text="Cancel"/>
        </EditItemTemplate>
        </telerik:GridTemplateColumn>

cs:

protected void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem item = (GridEditableItem)e.Item;
            RadTextBox txtbx = (RadTextBox)item["TemplateColumn"].FindControl("RadTextBox1");
            txtbx.Focus();
            txtbx.SelectionOnFocus = SelectionOnFocus.SelectAll;
        }
    }

Thanks
Princy.

how to find control on
  protected void RadGrid2_EditCommand(object sender, GridCommandEventArgs e)
        {
//find EditItemTemplate control
}

Hi Mayank,

You cannot access the Edit controls in the OnEditCommand event since the EditCommand is too early to access the edit form items, you can access the items in the ItemDataBound event of the grid instead as follows:

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem edit = (GridEditableItem)e.Item;
        TextBox txt = (TextBox)edit.FindControl("TextBox1"); //Access the EditItemTemplate control
        string value = txt.Text;
    }
}

Thanks,
Princy
