Equivalent of DataGridTableStyle for DataGridView?DataGridView? If not, is there an easy way to duplicate the DataGridTableStyle's functionality for the DataGridView? Here's the background for my question... Before I switched my application over to the Fx 2.0, I used a DataGrid to display my data. I would store different DataGridTableStyles (each one with a custom set of columns) in the DataGrid.TableStyles property and would use the DataGrid's ability to switch between these sets of columns depending on the source data. You could say that the DataGrid's DataGridTableStyle allowed you to have a set of "context sensitive" columns. If the data changed, so too did the columns used to view the data. But when I switched over to the Fx 2.0's DataGridView, I couldn't find an analog to the DataGridTableStyle. To get the same functionality, whenever I switch the data source of my DataGridView, I have to clear out the DataGridView.Columns and add the appropriate columns back. This method works, but is far less elegant than the way that the old DataGrid works. My initial idea was to store my sets of custom columns in different DataGridViewColumnCollection instances and set the DataGridView.Columns property as appropriate, but the DataGridView.Columns is read-only, so I couldn't do that. So, is there an easy way to assign a DataGridView columns in one step or am I stuck with my current method of clearing and reloading the columns every time? Thanks, - Mitchell S. Honnert PS: In the MSDN page "Differences Between the Windows Forms DataGridView and DataGrid Controls" (http://msdn2.microsoft.com/en-us/library/ms171628.aspx), it says this... "The only feature that is available in the DataGrid control that is not available in the DataGridView control is the hierarchical display of information from two related tables in a single control." I'm hoping that this statement is true and that I'm just overlooking the functionality in the DataGridView that equates to the DataGrid's DataGridTableStyle. Hi,
Setting the Datagridview's AutoGenerateColumns property to false will prevent the framework from adding the columns for you. There is not any tablestyle property for the datagridview. http://msdn2.microsoft.com/en-us/library/system.windows.forms.datagridview.autogeneratecolumns.aspx Ken ------------------- Show quoteHide quote "Mitchell S.

loading, but my question was intended to focus more on the setting of custom columns, especially on the possibility of switching between a predefined set of custom columns in the DataGridView. I understand that there is no DataGridViewTableStyle class which directly corresponds to the DataGridTableStyle, but I was hoping there might be a roughly similar feature in the DataGridView, albeit one that was implemented using a different approach. The quote in the Microsoft documentation about the DataGridView having all but one off the features of the DataGrid (see my original post) made me think that the "switch between predefined set of columns" feature was in the DataGridView *somewhere*; I just had to find it.

The DataGrid is still available in VS2005, why not continue to use it? Kerry Moorman Show quoteHide quote "Mitchell S.

DataGridView to warrant staying with the DataGrid. All in all, it's a good trade-off. There's only one thing that I ran across that the DataGridView can't do, and I have a workaround for that, so I don't regret the switch. I just wanted to make sure I wasn't missing a "DataGridView way" of switching between predefined column sets. - Mitchell S.

DataGridView it is associated with. So, it cannot be held as instances. However, as you are doing it, it can be cleared and refilled. Or, more than one DataGridView can be used, Hide()ing and Show()ing them as required. B.

DataGridViews, but one thing I didn't mention is that the underlying DataTable is the same for each of my custom column sets. It just seemed like overkill to have multiple DataGridViews just to support my different column sets. So, basically, it looks like I'll stick with my current solution of reloading the columns when I need to switch the column set. I was hoping that the DataGridView would have duplicated the DataGrid's DataGridTableStyle functionality somehow, but it certainly looks like this is not the case. Thanks again, - Mitchell S.

Honnert DataView. So, clearing the DataGridView and Fill()ing it again from the other DataView should (i'm guessing) be enough. Personally, i have Subs set my Column Collections (because other DataGridViews on other forms may use the same collection), by accepting a DataGridView as an input parameter. If i was handling your case, i'd most likely just recall the appropriate function using the same DataGridView, much like you expressed. B. |
