I'm trying to change the value in an editform before it becomes visible to the user. However the aspxgridview is always overwriting this.
This is my solution:

If (e.RowType = GridViewRowType.EditForm) Then

I have an aspxgridview which groups first by year and then by month. Basically my query returns Month and year as seperate columns. Now if I return month as "January or February" then ASPxGridview does not know how to sort this.
I heard of custom sorting, but even then if I return month column as a number and use dataitem template to convert it to a name...it works but then when exporting it only exports the number not the dataitemtemplate.
I am trying to display an error message in the edit section of a ASPxGridView when a user has tried to submit invalid data.I have been looking around and have found one blog that allows me to place an error message in red once it has filed validation by throwing a New InvalidOperationException.
I am using the rowUpdating method as described in the blog, but the exception forces my code to stop the code in visual studio (like you would at a break point) and displays the message. Once I click play again, the code carries on and the program continues. How do I stop the application from stopping once the exception has been called and carry on.

Any resolution to make the cascading dropdowns work as expected when used inside edit mode of AspxGridview. I am using DevExpress Controls.
My requirement is as follow:
If I select country="United States" then populate the "State" combobox and on selection of "State" populate the "City" combobox.
If I select "country" other then "United States" then populate only "City" combobox with cities of selected "country" and no need to populate the "State" combobox. Also I need to hide the "State" combobox. i.e. like
Country State City
ROW1 united states Alaska Douglas
ROW2 Canada Toronto
ROW3 Australia Sydeny
ROW4 united states California Yuba City
Same is required in Editmode also.
The MaskedEditExtender control that I am using is set up for a MaskType="DateTime" and the AcceptAMPM="true" but I need to know how a user can change the am/pm without having to type in A for AM and P for PM? Is there a way I can add arrows or something to this control so that it is more user-friendly when changing from AM to PM? My users aren't going to know that they need to type out the value for it to change.

I have Excel 2003 and 2007 loaded on my computer. When I open an Excel file, it is defaulting to 2003. How do I check to see what the default program is for opening xls files and change this to 2007 in my code? I have already done the following manually:
1-Open My Computer
2-Go to Tools --Folder options
3-Click the File Types tab
4-Scroll down to the XLS file type and highlight it

However I am not convince that its defaulting to Excel 2007 when I run projects in VB as I am seeing the "File Conversion" prompt when file are open.

I am inheriting my own DataGridView (say MyDataGridView) from the standard DataGridView control. What I want is that certain properties of MyDataGridView should have a different default value than what its base have. For example, AllowUserToAddRows, AllowUserToDeleteRows, AllowUserToResizeRows properties should have the default values of False; so that when I drag MyDataGridView into a form in the IDE, the default values shown in the properties grid should be False. Later on, if I want to change them to True from the grid, they will be set accordingly.

I feel as if it would work greatly with the amount of time taken to layout my programs.
