How to Set a DataItemIndex for a devexpress ASPxGridView

To Get a DataItemIndex in an ASPxGridView I suggest you add an unbound column to your ASPxGridView that will contain the row datasource index. Handle the server-side ASPxGridView.CustomUnboundColumnData event to provide data to this column. Use the ASPxGridViewColumnDataEventArgs.ListSourceRowIndex property to get the processed row's datasource index. Then, you can get data from this unbound column by using the server-side ASPxGridView.GetRowValues method. You can use this code to implement this task: After that, use this code to get the row's datasource index by its visible index:

Select distinct on one column but return all rows

ASPxPage Control Cannot unregister UpdatePanel - Post 2

Just had this issue again, this time without using tab pages. it looks like there are issues redirecting from an ASPxGridView row command. The only hack Devxpress can provide so far is re-registering the controls when they are unloaded. this obviously relies on microsoft never changing their code. To sort, all update panels need to reregister when unloaded! I added a method to my base page as follows: then this can be called on ALL updatepanel unloads

Intelliesense not working in Visual Studio

Hi Just a quick not to say about issues with intellisense not working in Visual Studio. I had controls registered in the web.config but intellisense was not picking them up.

It seems if there are any problems in the web.config file then intellisense wont work.

ASPxPage Control Cannot unregister UpdatePanel

I recently had a problem when using the Devexpress Page control wiht update panels in the pages. I have code to hide/show tabs based on certain settings, but the error: Cannot unregister UpdatePanel with ID 'upLoginActivityGrid' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported. Parameter name: updatePanel was shown by the .net runtime. after a little investigation this can easily be solved by hiding the tabs client side rather than server side. so changing the code from this: to this: solves the problem

Devexpress combobox datasource lost after postback

If you are using devexpress comboboxs and the datasource is null after postback. this may be becuase the combobox is set up to use multiple columns. If this is the case then multi column comboboxes need to be rebound on each postback to ensure the items still exist.

ASPxButton in RoundPanel used as an Update Panel trigger

If this does not work then you can register the control for postback directly with the current Script Manager

To fix this issue use the code below: Code Behind:

jqGrid Ensure last edited cell is saved when save button clicked

I had a jqGRid that is shown in a jQuery dialog. The dialog has a save and cancel button. A problem occured where the last column in the grid was edited, but as the user did not press enter to commit the cell value, the last value entered in the grid was not saved when the 'Save' button was clicked. To get around this, I saved the current row and column indexes in the afterEditCell Method, then called my custom save cell method (saveCurrentCell) when the OK button is clicked on the jQuery dialog. This ensures that the last cell being edited is saved before the dialog is closed. Markup: Javascript:

Error: Sys.ParameterCountException: Parameter count mismatch.

I had a gridview inside an update panel with a checkbox set to auto postback but every time it was clicked the parameter count mismatch error was being thrown by the ajax framework.
