How to merge the adjacent cells if they have the same value
As a workaround we can achieve the required behavior by hooking QueryCoveredRange event at sample level. Drawing cost will be increased a little as we are merging these at runtime. The following code explains the same.
C#
this.pivotGrid1.InternalGrid.QueryCoveredRange += new GridQueryCoveredRangeEventHandler(InternalGrid_QueryCoveredRange);
//To Merge cells if CellValue is same
void InternalGrid_QueryCoveredRange(object sender, GridQueryCoveredRangeEventArgs e)
{
if (e.CellRowColumnIndex.ColumnIndex > this.pivotGrid1.PivotRows.Count-1 && e.CellRowColumnIndex.RowIndex > this.pivotGrid1.PivotColumns.Count)
{
string cellValue = Convert.ToString(this.pivotGrid1.InternalGrid.Model[e.CellRowColumnIndex.RowIndex, e.CellRowColumnIndex.ColumnIndex].CellValue);
int count = e.CellRowColumnIndex.ColumnIndex + 1;
if (!string.IsNullOrEmpty(cellValue) && count < this.pivotGrid1.InternalGrid.Model.ColumnCount)
{
while (count < this.pivotGrid1.InternalGrid.Model.ColumnCount && cellValue == Convert.ToString(this.pivotGrid1.InternalGrid.Model[e.CellRowColumnIndex.RowIndex, count].CellValue))
{
count++;
}
e.Range = new CoveredCellInfo(e.CellRowColumnIndex.RowIndex, e.CellRowColumnIndex.ColumnIndex, e.CellRowColumnIndex.RowIndex, count);
e.Handled = true;
}
}
}
