DeleteRecordById(SequenceId,EmployeeId);

推荐答案

现在我希望其他人禁用该按钮，否则该按钮将无法查看.
只需在行数据绑定事件中将其禁用或隐藏即可.看来您已经做到了.

现在吗?

如果您要确认，那就可以了.看起来不错.

now i want that button to be disable for others or it should not be able to view.
Just disable or hide it in the row data bound event. Looks like you have already done that.

Now?

If you are confirming, then that''s ok. It looks good.

if (e.Row.RowType == DataControlRowType.DataRow)
{

//Check if user can delete it
string EmployeeId = Session["EmployeeId"].ToString();
//Get the Employee Object
//Check if user can delete this row

Button b = (Button)e.Row.FindControl("btnDelete");
if (user can delete the row)
{
  b.Visible = true;
  b.Attributes.Add("onclick", "javascript:return " +
  "confirm('Are you sure you want to delete this record " +
  DataBinder.Eval(e.Row.DataItem, "SequenceId")+ "')");
}
else
{
  b.Visible = false;
}
}

您不需要检查用户是否可以删除项目吗?我只会让那些有权删除它的用户看到它.

Don''t you need to check if the user can delete the item? I would only make it visible for those users who are authorized to delete it.
