Disabling delete button while editing Gridview

Couldn't you replace the 0 with the row index?

dgUserLevel.SelectedRows[0].FindControl("btnDelete");

Select allOpen in new window

Hello AvinashKN,

Because that is what you have told it to do: (Button)dgUserLevel.Rows[0] <- First row.

Depending on what event you are using this in you have various properties such as e.RowIndex or dgUserLevel.EditIndex which will allow you to specify the current row.

How do I specify the current row?

The SelectedRows property contains a collection of the currently selected rows. Since the user is editing, this will be one row. So, the following row is the current row:

dbUserLevel.Rows[0]

This should always work. Could you try this please?

I cannot specify rowindex either for whatever reason.

    protected void dgUserLevel_RowEditing(object sender, GridViewEditEventArgs e)
    {
        try
        {
            dgUserLevel.EditIndex = e.NewEditIndex;
            PopulateUserLevelDataGrid();
            Button btn = (Button) dgUserLevel.Rows[0].FindControl("btnDelete");
            btn.Enabled = false

Select allOpen in new window

AvinashKN,

Try this:

TimCottee

      protected void dgUserLevel_RowEditing(object sender, GridViewEditEventArgs e)
      {
          try
          {
              dgUserLevel.EditIndex = e.NewEditIndex;
              PopulateUserLevelDataGrid();
              GridViewRow row = (GridViewRow)((Control)e.CommandSource).Parent.Parent;
              Button btn = (Button) row.FindControl("btnDelete");
              btn.Enabled = false

Select allOpen in new window

Thanks for the help.

I'm getting the following error.

'System.Web.UI.WebControls.GridViewEditEventArgs' does not contain a definition for 'CommandSource'

I'm getting the following error:

Cannot apply indexing with [] to an expression of type 'System.Web.UI.WebControls.GridViewRow'

Thanks for the help pvginkel. It works.

I would also like to thank Tim Cotee. Since I'm a complete newbie to asp.net programming, his explanation was very helpful.

Thank you both.
