According to your project, Edit Form template controls are not bound to Data Source. (2) How do you add validation to this pop Up Edit Form approach? Please take a look at the Grid Editing - Validation online demo, illustrating the manual validation. Disclaimer: The information provided on Dev and its affiliated web properties is provided "as is" without warranty of any kind.Otherwise missing cells will be nulled out by the auto update operation. The dictionary consists of the new values to be set on the row's unbound cells.The hash key is the key of corresponding column and the value is the new value to be set.- How can I my attached example working with a custom edit template using this Enable Callback = false with Pop Up Edit Form mode and edit-visible-only columns ? Get Row Values method and set initial value template controls. To get the desired result, perform the following steps: 1) Handle the ASPx Grid View. We have reproduced the issue and our developers are presently working on it. Load Post Data Recursive method to prevent the mentioned behavior. Hopefully, these hints will help you achieve the desired result. I would rather not use the Session to store the data for 2 reasons: - If user closes browser or browser tab with this page, the data stays in the session. My current workaround is getting old Values from the aspxgrdiview using Get Row Values for the Editing Row Visible Index and getting new Values from the editformtemplatecontrol after using Render Utils. Columns["Category Name"], "Category Name is too long."), the Row Updating event is not called and the Pop Up Edit Form stays displayed on screen. - However, after this validation with error, the Pop Up Edit Form shows the original values instead of the modified values (that contain the error)!

Load Post Data Recursive for it (as you specified in your answer). If equal, then no db update is needed (values are not dirty).2) How do you add validation to this pop Up Edit Form approach? I can get the new Values from the editformtemplatecontrol and validate it's value. I do not need to load Post Data to the required controls explicitly via the Dev Express.
The hashtable contains former values of the row's cells.
If the grid contains templated columns or is bound to some of the fields from the data source, the Values and Old Values must be updated to add those missing values.
I have modified our project according to the information above and handled the ASPx Grid View. Please let us know whether this approach suits your needs. Load Post Data Recursive (as mentioned in your previous post) anymore which makes code much shorter and easier to understand.

If the values are alternated in the dictionary they are applied to the grid. The hashtable consists of the new values to be set on the row cells.If the values are alternated in the hashtable they are applied to the grid and carried over to the data source as well.
