[Solved] Pagination

[Sangeetha]

 In datagrid Itemtemplate column i have placed the textboxes(2 columns are textboxes and rest of the columns are label).Text 1 is amount text2 is percentage.
 Using JS calculated the percentage and amount in the onblur event.if user changes the data without saving the data then goes to page 2 then back to page 1 user lost the changes at that i want ask the user to save data then go to page 2.

 When the page index is changed, we lost the values of other pages.
When i change the page and then turn back, all the changes have been lost.

 while woking with DataGrids on the PageIndexChanged event i want to take a confirmation from the user to continue for the next page or not.
 
  How could i do this?

Hi Sangeetha,

You can use the approach from this example (handle window.onunload):

Hi,

Try the following code snippet.

CS:

 protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridPagerItem)
        {
            GridPagerItem pagitm = (GridPagerItem)e.Item;
            pagitm.Attributes.Add("OnClick", "return Confirm();");
        }
    }

JS:

 <script type="text/javascript" language="javascript">

         function Confirm()
         {
         alert('Move to Next Page?');
         }

     </script>

Hope this helps ..
Shinu.

Hi Sangeetha,

You can also try it in the following way.

CS:

  protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridPagerItem)
        {
         GridPagerItem pageritm=(GridPagerItem)e.Item;
         pageritm.Attributes.Add("OnClick", "return  confirm('Move to Next Page ?')");

        }
    }

Thanks
Princy.
