Radgrid Filtering problem..

[Lokesh]

Hi Team,
Greetings for the day..!!

I have a rad-grid with some template columns and some bound columns..
One column holds Amount .
If user enters some garbage value like ANVDSfdsfvgds@#$%  ..  in Amount column filter, I get some run-time error.
Same thing happens when garbage value is entered in Date column.
Is it possible to overcome this? Is there any way which can prevent user from entering such garbage values ??
Can we show some message to user saying "Please enter valid ....date or amount ..."

My tester is literally harassing me on this.. 

Any help appreciated.

Thanks, 
Lok..

Hello,

You can access the filtering item as shown below and apply validation as explained in this documentation.
C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
  if (e.Item is GridFilteringItem)
  {
   GridFilteringItem item = (GridFilteringItem)e.Item;
  }
}

Thanks,
Princy.

Lokesh:

You could use the approach that is covered in the following forum post to attach an "onkeyup" event to the textbox of the filter item for each column, associating it with a JavaScript client-side function that uses regular expressions to determine if the entry is valid.

Filtering Grid on ";" Character Causes Error

The difficult part of this will be to write the regular expressions required to validate for acceptable entries.

Hope this helps!
