Asked On March 22, 2005 03:59 PM UTC

In the following loop of code: foreach(Element theElement in grid.Table.DisplayElements) { if(theElement is CustomCaptionRow) { \\some action} } Is it possible to make that element the current row of the grid (move the grid cursor to that element and highlight the row)? A second question.... How can a user copy the values in a grid cell (either a record row or a summary row) and paste them to either another cell in the grid or another application? Thanks.

Hi Anthony, you should be able to call if(theElement is CustomCaptionRow) { theElement.ParentTable.CurrentRecordManager.NavigateTo(theElement); } Does that not work for you? In order to highlight the row you might need to handle TableControlPrepareViewStyleInfo. There you can check if the style.TableCellIdentity.DisplayElement is the the CurrentElement and then change the back color of the style. I can create a sample if needed. WRT to the copy/paste I''ll create a sample. Should this support pasting accross multiple rows or only multiple cells within one record? Accross multiple rows is much trickier. Do you need that?

Please create samples for all mentioned.

Sorry, my anwser should''ve been clearer... I''d like to copy/paste across both multiple cells and rows. >You didn''t answer my question ... > >>> >>>WRT to the copy/paste I''ll create a sample.

My requirements: 1- To copy a single cell value (detail, summary or group caption cell) to another cell. 2- To copy multiple cell values (one or many whole column''s worth of cells, or multiple rows of cells) and paste them to another app (notepad, textpad, etc...). >You didn''t answer my question ... > >>> >>>WRT to the copy/paste I''ll create a sample.

WRT to the NavigateTo problem. I added these lines to the sample: foreach (Element el in this.gridGroupingControl1.Table.DisplayElements) { if (el is ExtraSection) { el.ParentTable.CurrentRecordManager.NavigateTo(el); break; } } This seems to work find. What are you doing different? Can you modify the attached sample to show the problem? CS.zip I still need to work on a copy/paste sample. I will get back as soon as I have this. Stefan >Hi.

I assume you already implemented IGridTableCellStyleChanged.RaiseTableCellStyleChanged for those caption summary cells that you allow users to modify. The RaiseTableCellStyleChanged will be called after the PasteCellText event was raised. So, you could either save the pasted value in your store in the PasteCellText event or do it in your RaiseTableCellStyleChanged implementation. Stefan this.gridGroupingControl1.TableModel.PasteCellText += new GridPasteCellTextEventHandler(TableModel_PasteCellText); this.gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.Any; private void TableModel_PasteCellText(object sender, GridPasteCellTextEventArgs e) { Console.WriteLine("TableModel_PasteCellText: " + e.ToString()); GridTableCellStyleInfo style = (GridTableCellStyleInfo) e.Style; Element el = style.TableCellIdentity.DisplayElement; if (el is CaptionRow || el is CaptionSection) { Group g = el.ParentGroup; Console.WriteLine("Save text for grop {0} into storage for group summaries that you should have provided when you implemented IGridTableCellStyleChanged.RaiseTableCellStyleChanged", g.ToString()); } } Sample is here: CS.zip Stefan

WRT navigation: The call to el.ParentTable.CurrentRecordManager.NavigateTo(el); doesn''t highlight this display element for me. >WRT to the NavigateTo problem.

Ok, I assume you are using AllowSelection mode. With that mode you can manully force highlight a record by doing this: int rowIndex = el.ParentTable.DisplayElements.IndexOf(el); grid.TableModel.Selections.Add(GridRangeInfo.Row(rowIndex); Now the row should be drawn highlighted.

hi, and many thanks both works really fine !!! ( i was just having a problem activating extrasection ) would you please tell me howto navigate through grid rows to the next extrasection I am using TableControl_QueryNextCurrentCellPosition to handle my movements.

Hi Luis, try to handle the QueryAllowArrowKeyNavigateTo event. In your event handler you can check if e.Element is ExtraSection and in that case set e.AllowNavigateTo = true Stefan >hi, and many thanks both > >works really fine !!!

seems works fine, but iam using enter key to move from one section to another, is it another event to hook?, or am i have to work around this?

Hi Luis, the QueryAllowArrowKeyNavigateTo event still needs to be handled. In addition to that you could handle the CurrentCellKeyDown, e.g. private void gridGroupingControl1_TableControlCurrentCellKeyDown(object sender, GridTableControlKeyEventArgs e) { if (e.Inner.KeyCode == Keys.Enter) { Console.WriteLine("Enter"); e.Inner.Handled = true; Element current = e.TableControl.Table.CurrentElement; int index = e.TableControl.Table.DisplayElements.IndexOf(current); if (index != -1) { int count = e.TableControl.Table.DisplayElements.Count; while (++index < count) { Element el = e.TableControl.Table.DisplayElements[index]; // search for the next CustomSectionRow if (el is CustomSectionRow) { e.TableControl.CurrentCell.MoveTo(index, e.TableControl.CurrentCell.ColIndex); e.TableControl.InvalidateElement(el); return; } } } } } Stefan >seems works fine, but iam using enter key to move from one section to another, is it another event to hook?, or am i have to work around this?
