I've discovered the following methods for resetting the grouped columns, filters, and sorted columns, but I haven't found one for resetting the original column order. What's the easiest way to do this? I really don't want to persist the original grid state to disk.

DealGridControl.GroupedColumns.Clear();
DealGridControl.ShowFilters = false;
DealGridControl.SortColumns.Clear();

Thanks in advance,
Will.

Hi Will,

 

We have analyzed your requirement and we have achieve your requirement by using the following code snippet.

 

Code Snippet[C#]:

private void Order_Click(object sender, RoutedEventArgs e)

{

    foreach (KeyValuePair<int,string> it in Vcolorder)

    {

        int fromindex = this.SyncGrid.VisibleColumns.IndexOf(this.SyncGrid.VisibleColumns[it.Value]);

        this.SyncGrid.VisibleColumns.Move(fromindex,it.Key);                        

    }

}

 

We have prepared a sample based on this and it can be download from the following location.

 

Sample Location: GridDataControl_VisibleColumn.zip

 

Note:

·         Run the sample .

·         Re arrange the column by Column drag and drop.

·         Click the button Arrange order to rearrange the visiblecolumn

 

Please let us know if you have any questions.

 

Regards,

Raja sekar.G

Thank you. I will give this a try when I am next able to work on this.

Thanks, that method worked but is sub-optimal from a user standpoint. It would be really nice if you just exposed a Reset() method on the GridDataControl that resets the sorting, grouping, ordering, and filtering. How do I go about formally requesting that feature?

If you don't mind a related follow up, I'm now having trouble resetting the Filters on the VisibleColumns. I'm trying to do this:

for (int i = 0; i < gridDataControl.VisibleColumns.Count; i++)
{                                                                      gridDataControl.VisibleColumns[i].Filters.Clear();
}

But at certain points in my app the VisibleColumns.TableModel is null and the operation blows up with a null ref exception during your call to ApplyFilter().

Any suggestions?
