Grid control buttons

I have a gridview control that displays data returned from a DB. Datakey gridview property bound to db id column

Each entry in the GV had 2 buttons and one checkbox. When one of these controls is clicked, I want to get the row that the button was clicked on and take an action based on which control was clicked.

I was hoping I could use an event row_command

to capture which control was clicked, but that didn't do the trick unless I missed something.

You assign a button " CommandName

and CommandArgument

?

Also, the problem may lie in the wrong sequence of life cycle events. You should restore the data to your grid as soon as possible. Try to move the data binding to the eventPage_Init

Code for:

protected void gvCustomers_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName.Equals("RowSelected"))
    {
        GridViewRow row = (((e.CommandSource) as Button).NamingContainer) as GridViewRow;
        Label label = row.FindControl("lblFirstName") as Label;

        Response.Write(label.Text);
    }
}

And here's the ASPX View:

<asp:GridView AutoGenerateColumns="false" ID="gvCustomers" runat="server" OnRowCommand="gvCustomers_RowCommand" >

    <Columns>

        <asp:TemplateField>
            <ItemTemplate>

                <asp:Label ID="lblFirstName" runat="server" Text ='<%# Eval("FirstName") %>' />

           </ItemTemplate>
       </asp:TemplateField>

       <asp:TemplateField>
           <ItemTemplate>
               <asp:Button Text="Select" ID="btn1" runat="server" CommandArgument ='<%# Eval("FirstName") %>' CommandName="RowSelected" />
           </ItemTemplate>
       </asp:TemplateField>

    </Columns>

</asp:GridView>

<asp:GridView ID="gvProduct" runat="server" AutoGenerateColumns="False" DataKeyNames="ID"OnRowCommand="gvProduct_RowCommand" >
    <Columns>
       <asp:TemplateField>
           <ItemTemplate>
               <asp:ImageButton ID="btnEdit" runat="server" CommandName="EditCommand" Text="Edit" />
           </ItemTemplate>                                         
       </asp:TemplateField>
       <asp:BoundField DataField="ProjectNo" HeaderText="ProjectNo" />
       <asp:BoundField DataField="Date" HeaderText="Date" />
       <asp:BoundField DataField="Shift" HeaderText="شیفت" />
    </Columns>         
</asp:GridView>

and this code:

protected void gvProduct_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "EditCommand")
    {
        GridViewRow Row = (GridViewRow)((Control)e.CommandSource).NamingContainer;
        int productID = Convert.ToInt32(gvProduct.DataKeys[Row.RowIndex].Value);

        EditFunction(productID);
    }
}

EditFunction

is the function you set for the selected row and I removed it here.

Do you need something like this?
