GridView control with two asp:Command columns using the same command

Question

I have an ASP.NET GridView control with two asp:CommandField columns that are both using the Select command to perform different tasks. How do I distinguish which column was selected in the OnRowCommand event when both return "Select" when I check the CommandName property of the GridViewCommandEventArgs object?

Here is my source code:

ASPX page:

<asp:GridView ID="MyGridView" runat="server" AutoGenerateColumns="false" OnRowCommand="MyGridView_OnRowCommand">
    <Columns>
        <asp:CommandField ButtonType="Link" ShowSelectButton="true" SelectText="Click Me!" />
        <asp:CommandField ButtonType="Link" ShowSelectButton="true" SelectText="No Click Me!" />
    </Columns>
</asp:GridView>

Code behind:

protected void MyGridView_OnRowCommand(object sender, GridViewCommandEventArgs e)
{
    string x = e.CommandName //returns "Select" for both asp:CommandField columns
}

Answer 1

Use the GridViewCommandEventArgs.CommandArgument property !

Answer 2

Use a button column instead that way you can specify the specific command names and work with it from there

<asp:ButtonField ButtonType="Link" Text="Click Me" CommandName="MyCommand1" />
<asp:ButtonField ButtonType="Link" Text="No Click Me" CommandName="MyCommand2" />

Then you can take action based on e.CommandName

Answer 3

Well, first do you HAVE to use SELECt as the command? You could set that to something else that makes more sense.

Secondly, you could set the CommandArgument property to different values so you know which one is being clicked.

Answer 4

use the command argument property.

e.commandargument

Or you can dynamically create the button in the command field and set the commandName to anything you want.

in gridview_Load

for (int i = 0; i <= GridView1.Rows.Count - 1; i++) {

    linkbutton btnedit = new linkbutton();


    GridView1.Rows(i).Cells(3).Controls.Add(btnedit);
   //the above is where you want the button to be on the grid
    btndel.CommandName = "Select2";
    btndel.CommandArgument = "whatever you want";
}

Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
    If e.CommandName = "Select1" Then 

       //do stuff
End Sub
