c# - Method to Find GridView Column Index by Name

Question

I'm trying to write a small method to loop through and find a GridView Column by its Index, since it can change position based on what might be visible.

Here is what I have so far:

private int GetColumnIndexByName(GridView grid, string name)
{
    foreach (DataColumn col in grid.Columns)
    {
        if (col.ColumnName.ToLower().Trim() == name.ToLower().Trim()) return col.Ordinal;
    }

    return -1;
}

In this case, DataColumn doesn't appear to be the right type to use, but I'm kind of lost as to what I should be doing here.

I can only use .NET 2.0 / 3.5. I can't use 4.0.

Answer 1

I figured it out, I needed to be using DataControlField and slightly different syntax.

The working version:

private int GetColumnIndexByName(GridView grid, string name)
    {
        foreach (DataControlField col in grid.Columns)
        {
            if (col.HeaderText.ToLower().Trim() == name.ToLower().Trim())
            {
                return grid.Columns.IndexOf(col);
            }
        }

        return -1;
    }
