How to manually adding cell in ultraWebGrid
posted

I want to put some value in the ultraWebGrid. This is my code:

uwg = new UltraWebGrid();

 UltraGridRow ugRow = new UltraGridRow();
 uwg.Rows.Add(ugRow);

UltraGridCell ugCell = new UltraGridCell();
 uwg.Rows[Convert.ToInt32(rowTest["DTC01"])].Cells.Add(ugCell);
                                    uwg.Rows[Convert.ToInt32(rowTest["DTC01"])].Cells[Convert.ToInt32(rowTest["DTC02"])].Value = "allo";
wb.ContentPane.Controls.Add(uwg);

For me, I think this code can display "allo". I receive "no data can be display"

Why? and I want the text "allo" appear like a hyperLinkButton

Anyway Im lost, any help can be good.

    Define columns to add to your grid first.  Thus, when you add a row to the grid, it will get cells defined to match the column definitions - you don't need to create cell objects directly.

    I also recommend a different approahc to creating both your rows and your columns, which will ensure that they'll be stored in ViewState.

    using Infragistics.WebUI.UltraWebGrid;
    ...
    UltraGridColumn ugCol;
    ...
    ugCol = new UltraGridColumn(true); // Create the column and ensure it is stored in ViewState
    // Set other properties on the column here, such as its Key, its DataType, and its Header.Caption
    uwg.Columns.Add(ugCol);
    ...
    UltraGridRow ugRow;
    ...
    ugRow = new UltraGridRow(true); // Create the row and ensure it is stored in ViewState
    uwg.Rows.Add(ugRow); // This adds the row to the grid, and implicitly creates its cells
    // uwg.Cells.FromKey("MyColumn").Value = "allo";
    ugRow.Cells.FromKey("MyColumn").Value = "allo"; // Replace "MyColumn" with the Key property of the corresponding column
    ...
    wb.ContentPane.Controls.Add (uwg);

    EDIT:  Corrected a major typo in my original post.
