Get a reference to a control inside a RadGrid popup edit form

[Matt]

I have a radgrid that uses a popup edit form. I want to get a reference to a checkbox that is on this edit form using javascript. How can I do this?

Hi Matt,

I guess you want to access a GridCheckBoxColumn in Edit form popup. Please take a look into the following code snippet I tried to access the CheckBoxColumn in an External Button Click.

ASPX:

<asp:Button ID="button1" runat="server" Text="Test" OnClientClick="ClientClick() ;return false"/>

C#:

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
    {
        {
            GridEditableItem editForm = (GridEditableItem)e.Item;
            CheckBox chk = (CheckBox)(editForm["uniqueName"].Controls[0]);
            RadGrid1.Controls.Add(new LiteralControl("<script type='text/javascript'>window['check'] = '" + chk.ClientID + "';</script>"));
        }
    }
}

Javascript:

<script type="text/javascript">
    function ClientClick()
    {
        var EntityKeyName = document.getElementById(window['check']);
    }
</script>

Thanks,
Shinu.

This isn't exactly what I was looking for. What I wanted to accomplish was include a checkbox in an edit popup form and on the click event, either disable or enable textboxes on the same edit form. I decided to create a UserControl in my edit form and do it all server side instead. Seems to be much easier with an acceptable sacrifice in performance.
Thanks anyway.

Hi,

You can access the controls in usercontrol from server side as shown below.
C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
    {
        GridEditFormItem editItem = (GridEditFormItem)e.Item;
        UserControl userControl = (UserControl)editItem.FindControl(GridEditFormItem.EditFormUserControlID);
        CheckBox chk = (CheckBox)userControl.FindControl("CheckBox1");
        chk.AutoPostBack = true;
        chk.CheckedChanged += new EventHandler(chk_CheckedChanged);
    }
}
void chk_CheckedChanged(object sender, EventArgs e)
{
    CheckBox chk = (CheckBox)sender;
    UserControl ctl = (UserControl)chk.NamingContainer;
    TextBox txt = (TextBox)ctl.FindControl("TextBox1");
    txt.Text = "your text";
}

Thanks,
Shinu.
