Hi,

I am having a problem with the combination of gridview's select command and controls validation.

I have enabled (row) selection for a gridview which automatically generates a (select) link control. I have also a textbox control contained in the gridview's template field with a validation control attached to it.

The problem is that validation is not performed on the client side when the row selection link is clicked and a postback occurs even though CausesValidation property for the link is set to True by default and I set it to True explicitly <asp:CommandField ShowSelectButton="True" CausesValidation="True"/>.

I also have <asp:ButtonField CausesValidation="True" Text="Button" /> in my gridview that really causes validation on the client side before a postback but I would like to keep the row selection command to access the gridview's SelectedValue property. On the other hand, I need validation as well.

When moving the mouse over the two mentioned links I see that they call two different JavaScript functions, with <asp:CommandField ShowSelectButton="True" CausesValidation="True"/> calling _doPostBack apparently without validation on the client side. Maybe there is a way to force validation on the client side before all postbacks? Otherwise, to keep validation, I will probably have to extract which row was selected from the request object.

Sorted it out.

1.  Added a template field with a linkbutton to the gridview.

<asp:TemplateField>

<ItemTemplate>

<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click">LinkButton</asp:LinkButton>

</ItemTemplate>

</asp:TemplateField>

2.  Added the following code to handle the linkbutton's click event to extract the value ("SelectedValue") of the gridview's row linkbutton of which was clicked.

End Sub

 3. CausesValidation property of the linkbutton is True by default and client side validation works.
