    Hi,
    I don't know how i can assign a field of datatable as row caption.

    now after set Datasource do like this.

    for (int i = 0; i < Rows.Count; i++)
    {
    if (Rows[i].DataSource != null)
    Rows[i].Caption = ((DataRowView)Rows[i].DataSource).Row.ItemArray[1].ToString();
    }


    I need show a field value as row caption, this method is a bit slow.
    I forgot to day I need Merge the caption too.

    Thanks.

    Hi,

    There is no method to directly set Row Caption for the Grid. The code you've posted is currently the best way to do this.

    Hi,
    Thanks but it is slow when we have a lot of row in datasource
    I show the 50,000 record in grid it's have good speed but for caption make 3-4 times more.

    Regards.

    Hi,

    You can set your DataTable as DataSource for the grid, and set the style of the column having Row Caption field to Fixed style to make it look like a Fixed column.

    You can refer to the attached sample which makes column "OrderID" as fixed column and uses merging on that column.

    Regards.
