Asp.Net GridView get current row on TemplateField

I found out how to do it. You set the commandName property to whatever you want to call it inside the properties.

Then if you double click on the button after creating it in design view, it should pop up a function in the code behind page. You can then access the row by doing the following.

protected void gvUsers_RowCommand(object sender, GridViewCommandEventArgs e) {

 int rowNum = int.Parse(e.CommandArgument.ToString());

}

from there you can use the row number to access specific column data.

If you use a global variable to store the index of the row that is being selected, you can change that row back to the original color whenever a new row is selected.

Dim previousSelected As Integer 'global variable to store the last selected index
Protected Sub gvTransferOwner_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvTransferOwner.RowCommand
    If e.CommandName = "Select" Then
        Dim index As Integer = Convert.ToInt32(e.CommandArgument)
        Dim selectedRow As GridViewRow = gvTransferOwner.Rows(previousSelected)
        selectedRow.Style.Add("background-color", "#ffffff") 'change it back to original color
        selectedRow = gvTransferOwner.Rows(index)
        selectedRow.Style.Add("background-color", "#ffcccc") 'change the color of the new row
        previousSelected = index
    End If
End Sub
