Hi,

I would like to know how to implement client side validation on controls in edit mode of any row. LIke on clicking edit button we get the edit template dispalyed. Now let us say i have a text box which should take input as integer, if the user enters any value other integet i should give a error message. And this validation should happen on the client side itself may on text changed or on last focus and when the user clicks update button it should not allow the user to submit. Any help would be appreciated./

Hi Prasad,

I would suggest you to use a CustomValidator. You can place the CustomValidator in the EditItemTemplate and and you can perform the validation logic on the client side.

ASPX:
<EditItemTemplate> 
       <asp:TextBox id="TextBox1" runat="server" Text='<%# Bind("ContactName") %>'></asp:TextBox> 
       <asp:RequiredFieldValidator id="RequiredFieldValidator1" runat="server" ErrorMessage="*" 
        ControlToValidate"TextBox1"></asp:RequiredFieldValidator> 
     
 <asp:CustomValidator runat="server" id="CustomValidator1" 
        ControlToValidate="TextBox1" 
        ClientValidationFunction="CheckIntigers" 
        ErrorMessage="Invalid Input" /> 
 
 </EditItemTemplate> 


JS:
<script language="JavaScript"
  
    function CheckIntigers(sender, args) 
    { 
       
       
    } 
   
  </script> 


You can refer the following links to get more information regarding validation .

Hello Support Team,

I am using telerik Radgrid. In EditItemTemplate I have asp.net textboxes and for there validation I have asp:RequiredFieldValidator contols. these validation were working fine but I have need to use OnCommand client side event for edit case in my grid. When I implemented this event then validations are not working now by asp:RequiredFieldValidator as working before.its posting back to server code on OnItemCommand event without validating the fields.

 

I am sending my code example in attachment. Please provide my any solution.
