[Solved] Fire update command from control inside GridTemplateColumn

[ruslan opiu]

I have a RadTextBox in GridTemplateColumn, which should initiate updateItem() on AutoPostBack or TextChanged.
What is a right way to find containing GriDataItem and initiate updateItem()?

Hello Ruslan,

You can access the desired item via the NamingContainer property:

protected void RadTextBox1_TextChanged(object sender, EventArgs e)
{
    ((sender as RadTextBox).NamingContainer as GridItem).FireCommandEvent("Update", "");
}

Hello Ruslan,

It is not that easy to do the same on the client - the problem is to get the item index of the edited item. Try this workaround:

EditItemTemplate

<EditItemTemplate>
    <telerik:RadTextBox ID="RadTextBox1" runat="server">
        <ClientEvents OnValueChanged="valueChanged" />
    </telerik:RadTextBox>
</EditItemTemplate>

ValueChanged handler + global variable to hold the current index

<script type="text/javascript">
    var currentItem;
    function valueChanged(sender, args)
    {
        sender.get_parent().fireCommand("Update", currentItem);
    }
</script>

Initialize the variable on the server

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item.IsInEditMode)
    {
        RadTextBox rtb = (e.Item as GridEditableItem).FindControl("RadTextBox1") as RadTextBox;
        rtb.Attributes["onblur"] = String.Format("currentItem = {0};", e.Item.ItemIndex);
    }
}
