How to Validate textbox in grid on button click also in the grid

[Brendan]

So i have a textbox field that needs a few alerts and a confirm when a value is entered and the button in the grid is clicked to save the value of the textbox to the database.  How would this be achieved?

<telerik:GridTemplateColumn HeaderText="New Price" UniqueName="newprice">
<ItemTemplate> <asp:TextBox ID="txtNewPrice" runat="server" ></asp:TextBox> </ItemTemplate>
</telerik:GridTemplateColumn>
 <telerik:GridTemplateColumn HeaderText="Action" UniqueName="Action"> <ItemTemplate> <asp:Button ID="btnOverride" Text="Override" runat="server" OnClientClick="return Validate();" OnClick="Override_Click"></asp:Button> </ItemTemplate>  </telerik:GridTemplateColumn>

Hello Brendan,

 

Generally, RadGrid provides build-in validation capabilities:
https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/data-editing/validation

For this specific requirement, you can use the following approach:
Pass the button to the function:

OnClientClick="return Validate(this);"

function Validate(buttonEl){
  var button = $(buttonEl);
  var row = button.parents("tr").first();
  
  var textBox = row.find("#txtNewPrice");
  return textBox().val() == "";
}

Or .text();

I hope this will prove helpful.

Eyup
