linkbutton oncommand, onClick, RowCommand in grid view not firing

Question

I've read tens of posts about this issue and tried them all but with no luck, I'm not sure what am I missing this is gridview code:

<asp:GridView ID="recentJobsGridView" runat="server" CellPadding="4" ForeColor="#333333"
                            GridLines="None" Height="151px" Width="541px" Visible="False" AutoGenerateColumns="False"
                            PageSize="5" AllowPaging="True" OnPageIndexChanging="recentJobsGridView_PageIndexChanging"
                            DataKeyNames="orderItemId">
                            <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
                            <Columns>
                                <asp:TemplateField HeaderText="Order Date" Visible="true">
                                    <ItemTemplate>
                                        <asp:Label ID="Label1" runat="server" Text='<%# Bind("orderItemId") %>'></asp:Label>
                                    </ItemTemplate>
                                </asp:TemplateField>

                                    </ItemTemplate>
                                </asp:TemplateField>

                                        <asp:LinkButton ID="btAdd" runat="server" OnCommand="btAdd_Command"  Text="Add"

                                    </ItemTemplate>

                            <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
                            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
                            <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
                            <SortedAscendingCellStyle BackColor="#E9E7E2" />
                            <SortedAscendingHeaderStyle BackColor="#506C8C" />
                            <SortedDescendingCellStyle BackColor="#FFFDF8" />
                            <SortedDescendingHeaderStyle BackColor="#6F8DAE" />
                            <SortedAscendingCellStyle BackColor="#E9E7E2" />
                            <SortedAscendingHeaderStyle BackColor="#506C8C" />
                            <SortedDescendingCellStyle BackColor="#FFFDF8" />
                            <SortedDescendingHeaderStyle BackColor="#6F8DAE" />
                        </asp:GridView>

here is where I bind the grid view:

 protected void custGridView_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (custGridView.SelectedDataKey != null)
        {
            selectCustomer = (int)custGridView.SelectedDataKey.Value;
            recentJobsGridView.Visible = true;
            recentJobsGridView.DataSource = ViewDataSource(selectCustomer);
            recentJobsGridView.DataBind();
        }

    }

and this is the code of the LinkButton:

 protected void btAdd_Command(object sender, CommandEventArgs e)
    {
        if (e.CommandName == "Add")
        {
            StatusLbl.Text = "Hellooooooo";
        }
    }

I removed everything I just want this message to be displayed but NOTHING is responding Help please...

If you dont have the !Ispostback at the page load, the event from the gridview does not fire. — Wilfredo P

I had this issue. I was binding the data for the grid in the Page_PreRender, needed to do so in the page_load. — Jono

I see you are missing the onrowcommand in your gridview. Try this

asp:GridView ID="recentJobsGridView" runat="server" CellPadding="4" ForeColor="#333333"
                            GridLines="None" Height="151px" Width="541px" Visible="False" AutoGenerateColumns="False"
                            PageSize="5" AllowPaging="True" OnPageIndexChanging="recentJobsGridView_PageIndexChanging"
                            DataKeyNames="orderItemId"  onrowcommand="recentJobsGridView_RowCommand">

then add this to your codeFile

 protected void recentJobsGridView_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName.Equals("Add")) 
            {
              StatusLbl.Text = "Hellooooooo";
            }
        }

Try using the GridView's RowCommand event, which should fire on clicking the link button, with the command name/arg.

I think the problem is with binding the grid view when selecting a record from another gridview...what is the solution in this case??

Tadit Dash · Accepted Answer · 2013-10-01 12:37:01Z

Remove OnCommand="btAdd_Command", so LinkButton will be...

<asp:LinkButton ID="btAdd" runat="server" Text="Add" 
                CommandArgument='<%# Container.DataItem %>' 
                CommandName="Add">
</asp:LinkButton>

And add OnRowCommand="btAdd_Command" inside GridView.

<asp:GridView ID="recentJobsGridView" runat="server" CellPadding="4" 
              ForeColor="#333333" GridLines="None" Height="151px" Width="541px" 
              Visible="False" AutoGenerateColumns="False"
              PageSize="5" AllowPaging="True" 
              OnPageIndexChanging="recentJobsGridView_PageIndexChanging"
              DataKeyNames="orderItemId"
              OnRowCommand="btAdd_Command">

Now on Code Behind, modify the Button's definition like below...

protected void btAdd_Command(Object sender, GridViewCommandEventArgs e)
{
    // If multiple buttons are used in a GridView control, use the
    // CommandName property to determine which button was clicked.
    if (e.CommandName == "Add")
    {
        StatusLbl.Text = "Hellooooooo";
    }
}

Mark that you have to use GridViewCommandEventArgs, not CommandEventArgs.
