 |
|
hi,
i use Version 3.14. The VirtualTree contains 3 Colums (MainColum, SubColumn and CellEditorColumn)
It shoult looks like that
MainColumn
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
MainColumn
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
MainColumn
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
At the beginning all MainColums are collapsed and no CellEditor is visible .. that is right .. MainColums do not neet a CellEditor. If you expand a MainColumn the SubColumn and the assigned CellEditor is displayed.
If you expand a MainColumn which contains a large amount of SubColumns (height of all these SubColumns is larger than control height) than the MainColums get a CellEditor.
It looks like this
MainColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
MainColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
MainColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
+ SubColumn [CellEditorColumn]
| Code: |
protected override void OnGetCellData(Infralution.Controls.VirtualTree.Row row, Infralution.Controls.VirtualTree.Column column, Infralution.Controls.VirtualTree.CellData cellData)
{
base.OnGetCellData(row, column, cellData);
if (column == SubColumn &&
column.CellEditor != null)
{
column.CellEditor = new ComboBoxCellEditor();
}
} |
Any ideas to prevent the CellEditor on MainColumns?
regards

If you could put together a example project that replicates the problem (perhaps by modifying one of the standard sample projects) that would help greatly understanding and tracking this issue down. You can email a zipped copy to support@infralution.com.

Thanks for the sample project - that makes it much easier to see what the issue is. The problem is that your code in OnGetCellData is setting the column.CellEditor. This sets the default CellEditor that the base OnGetCellData method uses for cells. Once you have set this then all cells will then get that CellEditor.
Instead you should be setting the CellData.Editor - this sets the CellEditor for just the cell. Here is the code that works:
| Code: | private ComboBoxCellEditor _cellEditor = new ComboBoxCellEditor();
protected override void OnGetCellData(Infralution.Controls.VirtualTree.Row row, Infralution.Controls.VirtualTree.Column column, Infralution.Controls.VirtualTree.CellData cellData)
{
base.OnGetCellData(row, column, cellData);
if ((row.Item is SP.Adressen.AdressEigenschaftenManager.Eigenschaft))
{
if (column == this.m_ColumnWert)
{
cellData.Editor = _cellEditor;
}
}
} |
Note that you also had some redunant code in your OnGetCellData method that was checking if rows were visible and expanded etc. This is not required because OnGetCellData is only called when the row is visible.
