Check if column unique name exists in dynamic radgrid

[Jason]

Hi,

I use a dynamically created RadGrid which means the column unique names are not always the same. I perform some data modification on ItemDataBound based on a columns unique name which works as expected if the column exists.

    protected void grvReport_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = ((GridDataItem)e.Item);
            item["coltrainerList"].Text = item["coltrainerList"].Text.Replace(",", "<br/>");
        }
        // Other unrelated stuff
    }

Of course, if the column does not exist I get an error alert "Cannot find a cell bound to column name 'coltrainerList'". I expected this also - but I am unsure of how to determine if it exists or not. I tried the following:

if (item["coltrainerList"] != null) item["coltrainerList"].Text = item["coltrainerList"].Text.Replace(",", "<br/>");

Unfortunately, I still get the error alert. I have looked through the GridDataItem functions and not found one that can check if a unique column name exists in order to avoid this error.

Have I missed something?

Cheers.

I found a solution. I just need to use the FindByUniqueNameSafe function of the Item's OwnerTableView.Columns collection:

if (e.Item is GridDataItem)
{
     if (e.Item.OwnerTableView.Columns.FindByUniqueNameSafe("coltrainerList") != null)
     {
          GridDataItem item = ((GridDataItem)e.Item);
          item["coltrainerList"].Text = item["coltrainerList"].Text.Replace(",", "<br/>");
     }
}

No problems. It is always annoying when someone says "Never mind I found the answer" and doesn't bother posting it :)

Would you mind marking the post as answer just for completeness?
