RadGrid Clientside event Issue

[john]

Hi

I am using form edit in RadGrid. And am using following code.

<asp:Button ID="Button1" Text='<%# (Container is GridEditFormInsertItem) ? "Insert" : "Update" %>'
runat="server" CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>'>
</asp:Button>&nbsp;
<asp:Button ID="Button2" Text="Cancel" runat="server" CausesValidation="False" CommandName="Cancel">
</asp:Button>

But the problem is, it not at all firing the client side OnCommand event.

Please help me.


Thanks,
John.

Hello John,

As far as I know the grid can raise client Command event only from default grid controls. If you want to raise this from a button inside grid template you can use fireCommand() client side-method:
fireCommand.

Thank you very much shinu.

Fire command is working.

In my grid i used fire command to fire insert and update command.In that am validating few mandatory fields and showing alert message.

Message is displaying,but after clicking on ok. It is Posting back. I want to stop that post back.
Even i have given args.set_cancel(true) and return false.


Please help me to stop that post back.

Thanks,
John.

Hi John,

Normally in this case you should cancel the event and return from the function before calling fireCommand. The ASP button adds a standard __doPostBack call at the end, so you also need to return false after the client side call of the function if you are using such approach. Here is what worked on my end:

<asp:Button ID="Button1" Text='<%# (Container is GridEditFormInsertItem) ? "Insert" : "Update" %>' runat="server" OnClientClick="btnClick();return false;" CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>'>

function btnClick()
            {
                if (...something is wrong...)
                {
                    alert("message");
                }
                else
                {
                    //fireCommand(...)
                }
            }

All the best,
