Hide delete button on some rows?

[Leon Ham]

Hi,

Is it possible to hide the delete button on some rows in the grid?

I'm hiding the button in the ItemDataBound function, but when a row is clicked in the grid, the delete image is shown again.

Can anybody give me a sollution?

The RadGrid ClientSettings are:

<ClientSettings EnablePostBackOnRowClick="True" EnableRowHoverStyle="True">
   <Selecting AllowRowSelect="True" />
   <Scrolling AllowScroll="True" UseStaticHeaders="True" />
</ClientSettings>

Thanks

Hi Leon Ham,

I tried the following code in the ItemDataBound event of the RadGrid and its working as expected. Check for any differences with your code.

ASPX:

<telerik:GridButtonColumn ButtonType="LinkButton" Text="Delete" UniqueName="Delete" CommandName="Delete" >
</telerik:GridButtonColumn>
<telerik:GridBoundColumn DataField="User" HeaderText="User" UniqueName="User">
</telerik:GridBoundColumn>

CS:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        LinkButton deleteButton = (LinkButton)item["Delete"].Controls[0];
        if (item["User"].Text == "Non-Admin")
        {
            deleteButton.Visible = false;
        }
    }
}

Thanks,
Shinu.

Hi,

My code does something extra. Here is my code:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        DataRowView item = (DataRowView)e.Item.DataItem;
        if (item != null)
        {
            // "SystemGroup"
            if ((bool)item["SystemGroup"] == true)
            {
                // Disable delete
                TableCell cell = ((GridDataItem)e.Item)["delete"];
                ImageButton deleteButton = (ImageButton)cell.Controls[0];
                deleteButton.Visible = false;
                deleteButton.Enabled = false;
                cell.Text = " ";
        }
    }
}

This code shows the Delete button again if clicked on the row.
If the last line with cell.Text = " "; is removed, then everything is working as expected, but the layout of the row is less good.

Thanks
