I have a DataGridView with SelectionMode = "CellSelect". I do this because I want the user to be able to click the Column Header and drag the column to a different DisplayIndex. They move the column by clicking and holding down the left mouse button, then moving the column. I also want the user to be able to click the column header and all the cells in the column would be selected. But if I change the SelectionMode property to "FullColumnSelect" or "ColumnHeaderSelect" the user can no longer move the column.In the code below, I can select all the cells in the DataGridView just fine, but I can't select all cells in a particular Column or Row.

I'm trying to dynamically create a listview. on reports.aspx user selects a bunch of checkboxes. On the next page, user sees reports.aspx, and should see a table with columns of the checkboxes he selected. My idea was to create a listview, then dynamically change the header row of the LayoutTemplate, then change the select statement depending on which columns selected. This is what I have:
<asp:ListView runat="server" ID="ReportListView" DataSourceID="ReportListViewSDS">
<LayoutTemplate runat="server">
<table runat="server">
[Code]....
Problem is that this doesn't work because i can't put a code block (<%%>) inside the LayoutTemplate. Is there a way in the code behind to edit the LayoutTemplate, or another way to cycle through the Request.Form vars and build the table header row with it?

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?

I need to render a datagrid with different kinds of cells in the same column. For example, I have a datagrid with a column "name" and a colmun "value". Depending on the "type" of my record, I would have different cells in the column "value" like a combobox or a simple textfield. and I don't really see how to do that programmatically... I don't know if the datagrid is the best choice. I'm using asp.net/vb.net with framework 3.5

I have a DataGridView binded to a DataSet that I created using the Visual Studio Data Source Configuration Wizard. Everything works good except for one problem.I have two columns, Modified_By and Date_Modified that should be inserted or updated as the user and the current date, respectively. So every row in the DataGridView should have the same value for these two columns.So far, I have thought of two ways to get this working, but neither one seems very clean. The first idea is to make a custom Fill method that takes as parameters the user and the current date and then add them as extra columns in the select method. For example

I am currently working on my own listview control, and I was wondering if it was possible to get it to not draw the text for the listviewitem when the listview is in report mode? What I have been doing is putting all of my information in the tag and leaving the text property blank so it doesn't paint. Andis there a way to paint the background of the column headers? Because It only allows me to paint the actual column header? Here is what im talking about for the background of the column headers.

View 3 RepliesI have a windows application with many forms. We use the DataGridView control on most of the forms, but on a new form that I designed I have four DataGridViews. All of the DataGridViews on this form do not dipaly the Column Header Text when the form is displayed when running in the IDE. I do not receive any errors or messages. The other DataGridVeiws on other forms display their column header text just fine. I am at a loss as to why this is happining on this form.
UPDATE: If I add the desired text to the column.HeaderText property at the end of the form load event it displays the column header text. For example AssignedAmountColumn.HeaderText = "Amount" it displays Amount in the column when run from the IDE.... However it dosn't display when the property is set though the Columns property at design time.
Looking at deleting columns in excel and have found several threads that show how to delete an entire column which I have tested and done successfully. These columns were all identified by "A", "B", "C" and so on...
I was wondering if it was possible to do the same thing using the column headers. When deleting the columns in excel, one has to keep in mind that columns deleted from the left will shift the entire sheet to the left and if one is not careful, the next column[code]...
Let's say a user wants to delete the 'Middle' column (assume as column B in excel) and then delete the 'Suffix' column (assums as column D in excel). If they don't know to work from right to left when deleting columns, they would write code that would delete Column B and then repeat that code for Column D. However, once column B is deleted, all columns will shift left, which will result in the 'Phone' column (formerly column E now column D) being deleted instead of the 'Suffix' column (formerly column D now column C).
If there was a way to delete the columns by their headers (i.e. Middle, Suffix...) this would eliminate the problem; to me it seems a bit more intuitive as well.
I have a DGV that is populated at run time from a db query. One of the columns is sorted ascending and the column header for this column displays the little "up arrow" thing to signify it is sorted. I do not want the user to be able to click this (or any other column header) in this datagridview.
How can I maintain the column's visibility but disable the click function?
