Please give any suggestions.

Thanks in advance.

Hi Rags,

You can try out the following code to disable the next page/ previous page buttons:
c#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
 {
      if (e.Item is GridPagerItem)
        {
            GridPagerItem pager = (GridPagerItem)e.Item;
            if (check for condition)
            {
                ((Button)pager.FindControl("ctl03")).Enabled = false;
                ((Button)pager.FindControl("ctl12")).Enabled = false;

            }
        }
   }

Thanks
Princy.

Hi,

To disable the last page and next page button I have used follwing code.

((

 

Button)pagerItem.FindControl("ctl10")).Enabled = false;

 

((

 

Button)pagerItem.FindControl("ctl11")).Enabled = false;

But we cannot use because this ("ctl10") ID changes as number of pages increases.
Please suggest for the same.

Hi Ankit,

You could use jQuery in order to achieve your goal. Depending on your server logic, you could register client script that accesses the pager buttons using their class names and disables them:

function pageLoad(sender, args){
    $telerik.$('.rgPageNext')[0].disabled='true';
    $telerik.$('.rgPagePrev')[0].disabled='true';
}

All the best,
