Hello ,

Lets see If column "CategoryName" is the first column ,
So , first I'm writing :

radGridView1.DataSource = dtDataTable;

after this line goes code:

radGridView1.Columns.Remove("CategoryName");

GridViewMultiComboBoxColumn column = new GridViewMultiComboBoxColumn();

column.FieldName = "CategoryName";

radGridView1.Columns.Add(column);

the new column appears at the end , so I have to move it at the right place:

radGridView1.Columns.Move(radGridView1.Columns.Count - 1, 0);

But what happened with retrieved values of this column?
The column is empty.
So do I have to loop through and copy all the values from the removed column and assign them to the new one or there is a solution that all originally retrieved values are reflected in a new MultiComboBoxColumn?

In a case when I'm trying to assign the values .. it does not work because the cells after this assignment still empty...???? :

if (dtSource.Rows.Count > 0)

{

for (int i = 0; i < radGridView1.Rows.Count; i++)

{

radGridView1.Rows[i].Cells["c_price_lob"].BeginEdit();

radGridView1.Rows[i].Cells["c_price_lob"].Value = dtSource.Rows[i][3].ToString();

radGridView1.Rows[i].Cells["c_price_lob"].EndEdit();

}

Thank you ,
Victoria.

Actually , I'm waiting for the answer on the important question (second part of my previous post) : WHY the column which is bind to the datasource is empty?

The column in the gridview is empty. All other columns are populated from the datasource exept this one...
Please , see the picture attached...
The values are in the GridViewMultiComboBoxColumn. So when I open dropdown box the values are there.
In debugger I see that the column #3 HAS values, but why those values are not displayed in the gridview?
radGridView1.Rows[i].Cells[3].Value = "PO_1", but on the screen it's empty...?????

Please , I need an answer in C#.

Thank you,
Victoria.
