I am currently using a DataGridView coupled with a subform to implement a master/detail setup. The DataGridView only supports row selection and deletion events - editing/adding items is entirely handled in the subform. As such, I maintain a list of entities that I make changes to, while binding the DataGridView to a list of anonymous ty...
Is there a way to complex databind to a column's header text? Or is the only way to manually set the values and listen for change events from the source? For the record, I've tried both MyDataGrid.DataBindings.Add("Columns[<columnIndex>].HeaderText",MySource,"MyProperty"); and MyDataGrid.DataBindings.Add("Columns[\"ColumnName\"].Hea...
Hi Guys, I have two Datagridviews in a tab and the datasource of the second grid is based on the row selection in first grid. The problem is I cannot get the grid to refresh after some values have been inserted or updated in the prior tabs. It works fine if I click on the row but it is not working if I select the row programmatically (i...
I have a DataGridView, and I'm listening to its Scroll event. This gives me a ScrollEventArgs object whose Type member is supposed to tell me the type of scroll event that has occurred. On the MSDN documentation page it says I should be able to detect movement of the scroll box by listening for events with types ThumbPosition, ThumbTra...

These are fixed width, exept one that I have set up to take whatever space is left and fill the width of the view. The winform is resizeable in all directions.

Hello all, I'm used to using Telerik Grids and I'm able to display them in an outlook style, i.e. a picture on the far left, a bold title and a few other lines of text under the main title. Is there a way do this using a standard .Net2.0 Windows control? Either with a cheap control, or the existing datagridview or listview? Basically,...

I have a problem with binding data using BindingSource, typed dataset and DataGridView. My problem is: BindingSource, therefore grid, is empty after binding data (bindingSource.Count is 0). I couldn't figure out what I'm doing wrong and I'd be very happy if anyone could help me with this. My application structure is like this: I have two...
I need to apply formatting - specifically, bold text - to the tooltip used by a DataGridView in virtual mode. I can set the text in the CellToolTipTextNeeded event, but it doesn't support HTML tags; is there some other syntax I should be using? I don't want to have to reimplement tooltip support myself. ...
Hi there I can't quite work out how to allow a DataGridView populated at runtime to sort (when users click on the column headers) where a LINQ from XML query is the DataSource, via a BindingSource. Dim QueryReOrder = From Q In Query _ Where ((0 - Q.Qualifier) / cmbTSStakeValue.Text) <= 0.1 _ ...

MyObject has a public string property "MyProp". I want to display 1 column in the grid: showing the string values of the property MyProp of the MyObjec...
I have a DataTable which is populated from a CSV file then, using a DataGridView the data is edited in memory. As far as I understand the programmatic editing of the data should be done on the DataTable where the user editing is done via. the DataGridView. However when I add columns programmatically to the DataTable, it is not reflected...
I'm facing the need to enter "ragged" data in a WinForms application. Some columns are required for some types of entry lines and are not permitted on other entry lines, and the combo box data in later columns needs to vary based on the earlier columns. My question is: is there a better way to handle data that isn't quite as regular as ...
When the application is run, the DataGridView is bound to a DataTable. Later I add more columns to the DataTable programmatically and it is reflected in the underlying data - i.e. the column Ordinals are as they should be. However this is not reflected in the DataGridView. Instead columns are appended onto the originally generated set. ...

One user has half the updated / correct information (the other half is outdated) and the other user has half the information (the other half is outdated). User1: 25% + 25% = 50% current information needed the other 50% is ...
I have a table with say 1640 items. I set bindingSource.Filter = "some filter query string"; and most of the rows disappear, leaving, say, 400 rows. I'd like to be able to tell the user "Showing 400 of 1640 items" as they click some textboxes which change the filter string and hence which rows are visible in the dataGridView object (m...

I've got a DataGridView with a DataGridViewComboBoxColumn bound to a generic IList of CustomObjects. Here's a rough code sample of how I setup the column.
