Checked change event on GridCheckBoxColumn

[Jurjen Ladenius]

Hello,

I have a RadGrid in a control, the grid has a GridCheckBoxColumn. My question is how is it possible to attach a Checked Change event to the column. I tried to convert the column to a checkbox and then to attach the event and PostBack = true. It looks like he does a Postback but doesn't fires the event. Any idea how I could do this?

Thanks,

Jurjen

Hi Jurjen,

You can use the following code to achieve your goal:

        protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridEditableItem && e.Item.IsInEditMode)
            {
                GridEditableItem item = e.Item as GridEditableItem;
                CheckBox cb = (CheckBox)item["Bool"].Controls[0];
                cb.AutoPostBack = true;
                cb.CheckedChanged += new System.EventHandler(cb_CheckedChanged);
            }
        }

        void cb_CheckedChanged(object sender, System.EventArgs e)
        {
            RadAjaxManager1.Alert("checked changed");
        }

where "Bool" is the unique name of the check box column as in the first Grid here:

How can I reference other controls in the InsertForm from this event. I have a couple of comboboxes that I want to disable when this is checked?

Hi Colin,

You can access other controls as follows..

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
     if (e.Item is GridEditableItem && e.Item.IsInEditMode)
     {
         GridEditableItem item = e.Item as GridEditableItem;
         CheckBox cb = (CheckBox)item["Bool"].Controls[0];
         cb.AutoPostBack = true;
         cb.CheckedChanged += new System.EventHandler(cb_CheckedChanged);
     }
}

void cb_CheckedChanged(object sender, System.EventArgs e)
{
     CheckBox check = (CheckBox)sender;
     GridEditableItem eitem = (GridEditableItem)check.NamingContainer;
     RadComboBox combo = (RadComboBox)eitem.FindControl("RadComboBox1");
     combo.Enabled = false;
}

Thanks,
Shinu.
