Question

I’ve never personally used any of the Data controls within Visual Studio. I need to view and edit a two-dimensional byte array, 16×15 objects. Is there any control capable of editing this information?

I’ve tried to access data with the DataViewGrid, but am not sure how to use it.

It would be great to edit this information via rows and columns, like how you can in Excel.

Thank you!

Times like this I wish I could just use multiple text boxes and assign them each an index value. Oh VB6 how I miss you 😛

Following is part of my Array debug visualizer (ftp://missico.net/ArrayVisualizer.zip)

        //' x is columns
        //' y is rows

        //' x is first dimension
        //' y is second dimension

        //'create data table
        DataTable oData = new DataTable("Array");

        //'handle columns
        for (int x = 0; x <= _array.GetUpperBound(0); x++) {
            oData.Columns.Add(x.ToString(), typeof(string));
        }

        //'populate data
        for (int iRow = 0; iRow <= _array.GetUpperBound(1); iRow++) {
            DataRow oRow = oData.NewRow();
            for (int iCol = 0; iCol <= _array.GetUpperBound(0); iCol++) {
                oRow[iCol] = _array.GetValue(iCol, iRow);
            }
            oData.Rows.Add(oRow);
        }
        oData.AcceptChanges();

        //'data source
        __grid.DataSource = oData;

        //'handle row index
        int j = 0;
        foreach (DataGridViewRow oRow in __grid.Rows) {
            oRow.HeaderCell.Value = j.ToString();
            j += 1;
        }

        //'disallow sorting
        foreach (DataGridViewColumn oCol in __grid.Columns) {
            oCol.SortMode = DataGridViewColumnSortMode.NotSortable;
        }

        //'resize everything
        __grid.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.AllCells);
        __grid.AutoResizeRows(DataGridViewAutoSizeRowsMode.AllCells);
