Need to enable/disable commanditem based on no. of records in the grid

[Priyank]

Hello,

I have a linkbutton in the commanditem template.

I need to disable this linkbutton when the grid has 0 records.

Any help will be appreciated.

Thanks,
Priyank

Hi Priyank,

Please try the following code snippet to disable a LinkButton inside CommandItemTemplate.

ASPX:

<CommandItemTemplate>
    <asp:LinkButton ID="LinkButton1" runat="server">LinkButton</asp:LinkButton>
</CommandItemTemplate>

C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    RadGrid1.AllowPaging = false;
    RadGrid1.Rebind();
    int count = RadGrid1.MasterTableView.Items.Count; //Get the count of rows
    RadGrid1.AllowPaging = true;
    RadGrid1.Rebind();
    foreach (GridCommandItem cmditm in RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem))
    {
        if (count == 0)
        {
            LinkButton lnkbtn = (LinkButton)cmditm.FindControl("LinkButton1");
            lnkbtn.Enabled = false;
        }
    }
}

Thanks,

Hi Princy,

As per your suggested solution, the linkbutton is enabled and disabled as per the grid items count but now the collapse/expand button of grid item is not working and the linkbutton's click event is not getting executed.

Hi Priyank,

Please try setting the HierarchyLoadMode="Client" property in the MasterTableView of the Radgrid, also set the ClientSettings AllowExpandCollapse="true".

ASPX:

<MasterTableView HierarchyLoadMode="Client". . .>
. . . . . .
<ClientSettings AllowExpandCollapse="true"/>
