Hello Nikifor,

We are facing the same issue in the infragistics web 13.2.2.20132.2294. Rowspan we are acheive in the intialize event

function igrPaymentRequestForMedical_Grid_Initialize(sender, eventArgs) {
debugger;
var grid = $find("<%= igrPaymentRequestForMedical.ClientID %>");
var rows = grid.get_rows();
var totalRows = grid.get_rows().get_length();
var rowSpan = 0;
for (var count = 0; count < totalRows; count++) {
var currentRow = rows.get_row(count);
var CurrentCellElement = currentRow.get_cellByColumnKey('ConsultantName').get_element();
var RowspanValueElement = currentRow.get_cellByColumnKey('RowspanValue').get_element();

if (RowspanValueElement.outerText.trim() == "1") {
CurrentCellElement.rowSpan = 1;

}
else if (parseInt(RowspanValueElement.outerText) > 1) {
var rowspan = parseInt(RowspanValueElement.outerText);
for (i = rowspan - 1; i > 0; i--) {
var previousRow = rows.get_row(count + i);
var PreviousCellElement = previousRow.get_cellByColumnKey('ConsultantName').get_element();
PreviousCellElement.style.display = "none";
}
CurrentCellElement.rowSpan = parseInt(RowspanValueElement.outerText);
CurrentCellElement.ColSpan = 4;
}
}
}

When we set for Colspan is not working. Please help me how to proceed
