I'm using a richtextbox and I format the text (color) during keypress.. (like visual basic language: text in black, "dim" in blue, "comments" in green...) I use selection properies to do this, ok, work fine, but I see the selection and unselection.. Ok, is very fast, but it's annoying.. there is a way to format the text and hide the selection?

View 1 RepliesI have a listview that is populated with data. When I select a row the data is added to my textboxes for viewing editing etc. I want the row to stay focused while I am editing a textbox. I have set the property Hide selection to false for my list view but I still lose focus of the row.

I'm writing a standalone application in VB.NET using Visual Studio 2005. I want to display/hide a bunch of Buttons based on the selected value of a ComboBox. Each selection would have a different set of Buttons to display, and I'd like to have them arranged in a nice grid.
Driving a TabControl with the ComboBox value would be the kind of behavior I want, but I don't want it to look like a TabControl to the user because it might be confusing.Is there a way to do this?
Basically, I'd like Selection1 of the ComboBox to show Buttons 1-4, Selection2 to show Buttons 5-11, Selection3 to show (maybe) Buttons 1, 3, 5, 6, and 8, etc., have them arranged nicely, and have the GUI show only the ComboBox and the buttons.
I'm using SelectionMode as Extended (multi select) with WPF DataGrid.The SelectedIndex value always returns the first row that was selected, irrespective of the selection direction. For example, if I start at index 0 and end at 4, I can work with it fine. But if I start from 4 and go to 0, SelectedIndex returns 4 and I don't have a clue to add the number of selected cells or subtract.Is there a way to find the selection direction?
View 1 RepliesIt seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

To change this setting:
1. select the datagrid view tasks
2. Edit columns bound column properties
3. Select Width property
4. Width property will always revert back to the original setting.
I have check the properties settings without any luck.

Our site is developing against a 3rd party API (Wonderware) that returns datasets and datatables from certain calls. The issue we are having with some of the calls is the data returned is more than we want to show to the end users. We are binding the data to a datagrid, and will sometimes get back 20+ columns of data we don't need to show. Is there a way to filter the datatable of columns before binding it to the datagrid? Right now we are using the datagrid to hide the columns, but I think it would be better to strip out the columns of data we don't need before binding to the grid.

I'm having an issue wherein after I run a search filtering a datagrid, the corresponding datadetails will not update anymore when a new item is selected in the datagrid.I would like it so after clicking an item in the datagrid, the details update automatically.

To clarify, the search itself filters the datagrid perfectly as intended....it just seems to stop the details from updating when new items are selected which is my problem.
I am still having issues with the combo box. I have the correct query. I have four tables in MS Access. I need to create a form in Visual Basic that has a combo box and a datagrid. The selection from the combo box will display all relevant information about that person on the datagrid. For example, if I select John Doe (from the combo box) the datagrid should display: [Code] How do I add John Doe to the combo box and link this query to it, when upon being selected, it displays the result in the datagrid?
View 1 RepliesAm using vb.net 08 and i have a datagridview with 3 columns. The first column has a button as the columntype with the name "UserName". Now, i want if the user clicks only on the UserName which is the first column, but not the entire row, it should display the value of the UserName column only. If other columns are clicked are apart from the UserName, nothing should display. So there will be a for loop that will itera te through all the rows of the datagridview.
So i have something like this:
