Hi,

I am validating a GridDateTimeColumn client side. Here is my code:

Protected Sub gridRemarques_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles gridRemarques.ItemCreated

If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then

Dim eItem = CType(e.Item, GridEditableItem)

Dim lnkInsert As linkButton = eItem.FindControl("PerformInsertButton")

Dim lnkUpdate As linkButton = eItem.FindControl("UpdateButton")

If lnkInsert IsNot Nothing AndAlso e.Item.OwnerTableView.IsItemInserted Then

lnkInsert.OnClientClick = "return Validate()"

Else

lnkUpdate.OnClientClick = "return Validate()"

End If

End Sub

This was working. I just change my linkButton for PushButton and even though the return is true or false, UpdateCommand/InserCommand is never fired... I tried some solutions on the forum, but I had no result.

My JS Validate() is simply like that for the moment:

function Validate()

{

return true;

}

Thanks.

Hello,

I tried the same scenario with PushButton which worked as expected. Here is the sample code.
aspx:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" DataSourceID="SqlDataSource1" OnInsertCommand="RadGrid1_InsertCommand" OnItemDataBound="RadGrid1_ItemDataBound" OnUpdateCommand="RadGrid1_UpdateCommand">

<MasterTableView CommandItemDisplay="Top">

<editcolumn buttontype="PushButton"></editcolumn>

<Columns>

<telerik:GridEditCommandColumn ButtonType="PushButton"></telerik:GridEditCommandColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

VB:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs)

If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then

Dim itm As GridEditableItem = DirectCast(e.Item, GridEditableItem)

Dim btn As Button = DirectCast(itm.FindControl("UpdateButtonButton"), Button)

btn.OnClientClick = "return validate()"

End If

End Sub

Please provide your complete code if it doesn't help.

I tried a sample project and it worked on 2011.3.1305.35, but on 2012.1.215.35 it's not working anymore...

Edit: I just went back to 2011.3.1305.35 and still not working.

Is that a known issue?
