Binder in GridGroupingControl

[Administrator]

I''m using the GridGroupingControl the first time and looking for the Binder property. Exists an equivalent class or do we have to use the BindingContext directly? I''m often using the Binder.Suspend/ResumeBinding() methods in the GDBG and I''ll port the code to the GridGroupingControl.

Thanks

Hi Thomas,

grouping control has no Binder property.

To achieve similar results to Binder.Suspend/ResumeBinding() you should set
groupingControl.Table.TableDirty = true.

This tells the grid that the table is dirty and subsequent ListChanged events can be ignored.

Once the grid gets displayed or you access records (e.g. call Record.SetCurrent) the table will be categorized.

Hi Stefan

Thanks for you response.

In the GDBG, I''m using the following code when I replace the data in the grid:

this.grdData.BeginUpdate()
this.grdData.Binder.SuspendBinding()

-- replace the data by merge into the DataSet

this.grdData.Model.ResetVolatileData()
this.grdData.Binder.ResumeBinding()
this.grdData.EndUpdate()
this.grdData.Refresh()

What is the correct way in the GroupingControl when I''m updating the whole data.

Thanks
Thomas

Try this:

this.grdData.BeginUpdate()
this.grdData.Table.TableDirty = true

-- replace the data by merge into the DataSet

this.grdData.EndUpdate(false)
this.grdData.Refresh()

In earlier versions there was no BeginUpdate / EndUpdate methods on GridGroupingControl. You can then just call this.grdData.TableControl.BeginUpdate() instead.
