Hi all, I have a DataGridView binded to a DataTable.
I want to insert a DataGridViewLinkColumn not binded to a Datatable's field but I'm not able to display different values in that column's cells.

If I set UseColumnTextForLinkValue = true it displays the same value in each cell (the value I specified in Text property).

If I set UseColumnTextForLinkValue = false it displays nothing even though I set my own values in each cell.

What should I do to display different values?

TIA.

I've linked my DataGridView to a DataSource.
After I've added a new column (a DataGridViewLinkColumn) not included in the Datasource, I want to write different links in that column, but I can't.
If I specify UseColumnTextForLinkValue = true in the cell's column appears the same value; If I specify UseColumnTextForLinkValue = false in the cell's column appears no value.

Below my code:

DataGridViewLinkColumn l_Warning_Agente = new DataGridViewLinkColumn();
l_Warning_Agente.Name = WARNING_COLUMN_NAME;
l_Warning_Agente.HeaderText = "Warning Agent";
l_Warning_Agente.Width = 100;
l_Warning_Agente.ReadOnly = false;
l_Warning_Agente.FillWeight = 10;
l_Warning_Agente.ValueType = Type.GetType("System.String");
l_Warning_Agente.UseColumnTextForLinkValue = true;
//l_Warning_Agente.DataPropertyName = ObjSimPaz.CAMPO_AGENTE_DESCRIZIONE_AGENTIPROPOSTA_TSP24;
l_Warning_Agente.Text = "Warning";
l_Warning_Agente.LinkBehavior = LinkBehavior.SystemDefault;
l_Warning_Agente.LinkColor = Color.Blue;
l_Warning_Agente.TrackVisitedState = true;
dgvTable.Columns.Add(l_Warning_Agente);

foreach (DataGridViewRow dRow in dgvTable.Rows)
{
dRow.Cells["SP24_WARNING"].Value = "
}

I've solved my question. I set different values in DataGridViewLinkColumn in the form's load event. It was my fault...

Hello,

You can add TableCell by implementing the handler of a GridView RowDataBound event.

For example:

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                TableCell newcell = new TableCell();
                newcell.Text = "123";
                e.Row.Cells.Add(newcell);
            }
        }

To access cells in specific columns use this example:

C#

string Contract = DataBinder.Eval(e.Row.DataItem, "Contract").ToString();

Hope it helps.
