Avoid sorting of header rows at the time of binding of data to GGC

[Awanish]

Hi,

I am facing one problem in GridGrouping control.When i bind data to GGC, all the header row are sorted by default on the basis of GroupColumn.I don't want this default behaviour. Please help me.

Here is the code I am using to bind the GGC:

grdWbsTask.DataSource = ProjectScopeManager.ScopeSubTaskDT;
grdWbsTask.ChildGroupOptions.CaptionText = "{Category}";

grdWbsTask.TableDescriptor.GroupedColumns.Add("group");
GridColumnDescriptor subTaskName = new GridColumnDescriptor();
subTaskName.Name = "name";
subTaskName.MappingName = "name";
subTaskName.HeaderText = "Name";
grdWbsTask.TableDescriptor.Columns.Add(subTaskName);

GridColumnDescriptor constantHours = new GridColumnDescriptor();
constantHours.Name = "loe_constant_hours";
constantHours.MappingName = "loe_constant_hours";
constantHours.HeaderText = "LOE(Hours)";
grdWbsTask.TableDescriptor.Columns.Add(constantHours);

When i bind data to GGC ,all header rows are sorted by default on the basis of "group" column.


Thanks,

Hi Awanish,

Thank you for your interest in Syncfusion products.

The Grouping is followed by sorting in GridGroupingControl. This is by design. You cannot prevent sorting when the column is grouped. However, it is possible to control the sorting order by adding a custom Comparer to the SortColumnDescriptor. Here is a minimal sample to do this.

You can modify the sorting order by customizing the Comparer method in the way you want.
Here is a forum link that discusses on how to use the custom sort while grouping.
