[Solved] Trap ItemCommand of Hyperlink radgrid column

[Kerry]

Hello, I'd like to trap the click event of a RadGrid column that is defined as asp:HyperLink.  I need to set some server-side variables before redirecting the user to another webpage.  THis was very easy when the column was a ButtonColumn but I had to change to a Hyperlink , I would trap the ItemCommand event then test the e.CommandName arguement then set my variables and redirect the user, but it seems the ItemCommand event is not fired when I click the hyperlink.

Thanks

Hi Kerry,

One suggestion would be using LinkButton instead of HyperLink and set the CommandName for LinkButton, then in ItemCommand event check for e.CommandName to redirect the page explicitly.

ASPX:

<telerik:GridTemplateColumn UniqueName="TemplateColumn2">
    <ItemTemplate>
        <asp:LinkButton ID="LinkButton1" CommandName="Redirect" Text="Click button" runat="server"></asp:LinkButton>
    </ItemTemplate>
</telerik:GridTemplateColumn>

C#:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
    if(e.CommandName == "Redirect")
    {
        Response.Redirect("http://www.google.com");
    }
}

Thanks,
Princy.

Yes I see now, thanks..... I also notice that the ItemCommand event will not fire if I also set [onclick] attribute for the LinkButton....is there a way to have the ItemCommand event fire when there is a Javascript call on the [onclick] event.  I set a call to a Javascript fucntion on the ItemDataBound event.

Thanks

Hi Kerry,

I tried calling a JavaScript function on the clicking the linkbutton and it was firing the the ItemCommand event once the client side function returns true. Here is the sample code:

ASPX:

<telerik:GridTemplateColumn UniqueName="TempCol" HeaderText="TempCol" >
                         <ItemTemplate>
                          <asp:LinkButton ID="LinkButton1" CommandName="Redirect" Text="Click button" runat="server"  ></asp:LinkButton>
                         </ItemTemplate>
                        </telerik:GridTemplateColumn>

CS:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            LinkButton lnkbtn = (LinkButton)item["TempCol"].FindControl("LinkButton1");
            lnkbtn.Attributes.Add("onclick"," return Show();");
        }
    }

JS:

<script type="text/javascript" >
 function Show()
 {
  if(confirm("You want to proceed?"))
    return true;
    else
    return false;
 }
</script>
