GGC Sorting Header Row

[samanvay Gupta]

Hi,

Can you please help me to sort header row of GGC.
I want to sort header row using a field which is in the same datasource but not binded to the header or child row.

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);

Thanks
Saman

Hi Samanvay,

Thank you for your interest in Syncfusion product.

I am unable to reproduce the issue in sorting, when the column has been added manually in GridGroupingControl. I have created the sample with specified your code in GridGroupingControl, the header sorting had performed in GridGroupingControl. Also I have attached the sample in below link:
http://files.syncfusion.com/support/samples/Grid.Windows/Forums/GGCBindColumn.zip

This sample shows the sorting in GridGroupingControl.

Please try this sample, let me know if I misunderstood the query.

Regards,
Lingaraj S.

Hi Lingaraj,

Thanks for your quick comment on this. I probably could not explain the problem correctly.

Attached is the sample which I have created to explain the problem. In this sample I would like to sort header row (currently 3 rows) programmatically by "task index" field. Currently header rows are sorted based on thier caption.

task index field is associated with child rows but it will remain same for all the rows of that group

Thanks
Saman

Hi Samanvay,

Thank you for the update.

If you want to sort grouped column by clicking another column, then please try using ListSortSortDirection property in GroupedColumns by applying in TableControlCellClick event to achieve this behavior.

Refer the code below:

void gridGroupingControl1_TableControlCellClick(object sender, GridTableControlCellClickEventArgs e)
{
GridTableCellStyleInfo sty = this.gridGroupingControl1.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex);
if (sty.TableCellIdentity.TableCellType == GridTableCellType.ColumnHeaderCell && sty.TableCellIdentity.Column.Name == "task_index")
{
System.ComponentModel.ListSortDirection sort= this.gridGroupingControl1.TableDescriptor.GroupedColumns["group"].SortDirection;
if (sort == ListSortDirection.Ascending)
{
sort = ListSortDirection.Descending;
this.gridGroupingControl1.TableDescriptor.GroupedColumns["group"].SortDirection = sort;
}
else
{
sort = ListSortDirection.Ascending;
this.gridGroupingControl1.TableDescriptor.GroupedColumns["group"].SortDirection = sort;
}
e.Inner.Cancel = true;
}
}

Refer the modified sample in below link:

Please let me know if you have any queries.
