Forms Data Controls :: GridView Delete Command Fires Error When Using Template Fields Inside
Mar 6, 2011I have visual 2010 with net 3.5 web app. I was implementing EntityFramework in my project and added a gridview to a entity source control. It worked ok, with select, update, and delete buttons enabled on the grid. But then, i needed to add a template field bound to a Foreign table, so my users select value from a list instead of writing the code. After that, my app fires error when i delete. I tried everything, inclue dakeyNames, write code on my RowDeleting, RowDeleted, RowCommand, but error persists.
Now, i can delete the row, but it then i get the error Object reference not set to an instance of an object If i implemente delete code on RowCommand i get the error: Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries.

Forms Data Controls :: Error On Pressing Button In Gridview Template Field?
Feb 1, 2010I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Below is my code

Forms Data Controls :: EditItem Template Of Gridview - Template Field With Dropdown List - How To Make Current Value Sel
Dec 4, 2010Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.
View 3 RepliesForms Data Controls :: How To Navigate To The Last Page In Gridview
Aug 25, 2010I have a gridview which has paging enabled in it.
In my gridview I have a button which adds a new row to the grid. The problem i am having is that when the user clicks this add row button, it needs to go to the last page and add a new row there.
At the moment when I click the button i get an error saying - Index was out of range.
I'm sure this is because the method i am using doesn't know how to get to the last page... it needs to do this no matter what page the user is on
The method i use to add a new row is as follows: how i can adapt it to recognise the last page and row position in the gridview?
