Hello,

You can merge the cells having same values using the following code

C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

for (int rowIndex = RadGrid1.Items.Count - 2; rowIndex >= 0; rowIndex--)

{

GridDataItem row = RadGrid1.Items[rowIndex];

GridDataItem previousRow = RadGrid1.Items[rowIndex + 1];

for (int i = 0; i < row.Cells.Count; i++)

{

if (row.Cells[i].Text == previousRow.Cells[i].Text)

{

row.Cells[i].RowSpan = previousRow.Cells[i].RowSpan < 2 ? 2 : previousRow.Cells[i].RowSpan + 1;

previousRow.Cells[i].Visible = false;

}

}

}

}

In this example, if a cell value is the same as a value in the next (lower) row, then its RowSpan is increased and the lower cell is made invisible.

I wanted to do this same thing, but on a grid that is bound on the client side. Here is the above solution for this case, using an onDataBound client event.

Note that in Shinu's code above, the function checks every column for shared values between rows. In the code below, I have a column with the UniqueName "num" that is the column I want to merge.

function rgDataBound(sender, args) {
    var rows = sender.get_masterTableView().get_dataItems();
    var nRows = rows.length;
    if (nRows > 1) {
      for (var r = nRows - 2; r >= 0; r--) {
        var row = rows[r];
        var prevRow = rows[r + 1];
        if (row.get_dataItem().num == prevRow.get_dataItem().num) {
          row.get_cell("num").rowSpan = prevRow.get_cell("num").rowSpan < 2 ? 2 : prevRow.get_cell("num").rowSpan + 1;
          prevRow.get_cell("num").style.display = "none";
        }
      }
    }
  }

Hello Tom,

Generally, merging rows or cells is not supported by default and thus beyond our support scope. You can try your own custom approaches based on your requirements.
