Hi,
I would like to loop through each column of a datagridview control.
If the header contains the word "hello" i.e. "you hello", then it is to be replaced with a new word such as "great"
This is what I have but not sure how to replace

C#

foreach (DataGridViewColumn col in dgv.Columns)
            {
                string strColumn = col.HeaderText.ToString();
                
                if (strColumn.ToLower().Contains("hello"))
                {
			//col.HeaderCell.Value = ""

Any suggestions please?
Thanks

Why? Why not putting it right in first place?

The property System.Windows.Forms.DataGridViewColumn.HeaderText has the type string, so HeaderText.ToString() in your code is pointless.

Also, this property is read-write; and it makes the whole question pointless. You can assign a string value to it, not just read. This is the solution you wanted.

Please see: http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcolumn.headertext.aspx[^].

Finally, think at my comment to the question: why? This is a rhetorical question; just think about it. :-)

Solution 2

Try:

C#

foreach (DataGridViewColumn col in dgv.Columns)
{
   col.HeaderText = col.HeaderText.Replace("hello", "great");
}
