Programatically Navigating a Grid Grouping Countrol

[Bill Langlais]

Hi,

I have a Grid Grouping Control bound to 5 DataTables which are nested from level 1 though 5. The data in the grid is also displayed in tab control graphically where there is a tab for each row at the third level and the data at the 4th and 5th level are drawn on the tab page.

I want to be able to programatlically position the correct rows in the grouping grid, expanding where necessary, so that a user can select something in a particular tab page and have the coresponding row at either the 4 or 5 level positioned and selected so the user can see the coresponding data.

I have two questions:

How do I locate data in the grid using the data in the DataTable regardless of how the user may have sorted the rows at a particular level.

How do I position and select the apropriate rows in the grid so that they are visable.

Thanks for your help

Hi Bill,

Issue 1:

Use the SortedColumns property in GridTableDescriptor to sort the table in a grid. Below is a code snippet

GridTableDescriptor gd = this.gridGroupingControl1.GetTableDescriptor("ChildTable");
if( !gd.SortedColumns.Contains("childID") )
gd.SortedColumns.Add("childID",ListSortDirection.Descending);

Issue 2:

To make a record as SelectedRecord, you can call the SelectedRecords.Add method. Here is a code snippet,

GridTable gt = this.gridGroupingControl1.GetTable("ChildTable");
this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.One;

//Add the record to the selection.....
gt.SelectedRecords.Add(gt.Records[0]);

To set the record as current record, you need to call the SetCurrent() method.
gt.Records[0].SetCurrent();

Let me know if this helps.
Best Regards,

Hi,

Thanks for your response.

On Issue 1:

I want to find a record in the grid programatically without effecting the way the grid is sorted or apears to the user so that I can highlight it in issue 2.

Hi Bill,

Sorry for the inconvenience caused.

To find the record index, you can use the IndexOf method in UnsortedRecords collection. Below is a code snippet

int unsortedIndex = this.gridGroupingControl1.Table.UnsortedRecords.IndexOf(record);

int sortedIndex = this.gridGroupingControl1.Table.Records.IndexOf(record);

Thanks,
