Asp net gridview rowupdating e oldvalues
Now on clicking update link it fires Row Updating method and there i found e.newvalues.count = 0. Thank you for taking interest in this matter Allen.
I want to validate the user input before my row is updated. Datagrid(1.1) to Grid View(2.0) and using the Row Updating event how to extract the values from the controls.
I have a Grid View control and use old style manual binding with a Data Source property and invoke the Data Bind() method.
If you don't use one of the Data Source controls, you are required to handle the Row Updating event.
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)! Regards, Jenny Dear, Binding the controls in the popup editform (aspx) seems to solve all the issues.
We appreciate your patience while we work to find a solution to your inquiry. If you need any further help on this subject, please feel free to reactivate this ticket. This can become a storage problem when having a lot of simultanous users on the server. 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.
