Checking if column exists in GridDataItem

[Eliyahu Goldin]

This code will throw an exception:

                        GridDataItem dItem = e.Item as GridDataItem;
                        // rename edit button
                        TableCell cell = dItem["cmdEdit"];
                        if (cell != null)
                        {
                            Control control = cell.Controls[0];
                            if (control != null)
                            {
                                LinkButton cmdEdit = control as LinkButton;
                                cmdEdit.Text = "View";
                            }
                        }

Instead of handling exceptions, I would rather prefer to check if the column exists prior to accessing it. I couldn't find any simple way of checking column existense by unique name.

Why don't you introduce a method GridDataItem.ContainsColumn(uniqueName) ?

Hello Eliyahu,

You can use RadGrid1.MasterTableView.GetColumnSafe(); in order to check if the given column exist.

Also you to modify your code a bit:

if (cell.HasControls())
{
    Control control = cell.Controls[0];

This will prevent exceptions when there are no controls in the current cell.
