Forms Data Controls :: Dynamic GridView RowUpdating Event Handler Will Not Run?
Feb 1, 2010I'm creating a GridView in code. I can successfully attach handlers for Editing, and CancelEditing. RowUpdating never runs, however. Instead, if the GridView is in a Panel, the Edit handler is called when Update is clicked (and this is the command name I get back on the Update click, too). If the GridView is not in a panel, then the Cancel handler is called when Update is clicked (again, this is the command name I get back from clicking Update). I've searched high and low for a reason why the RowUpdating event is not getting called, and I can't find one. Does anyone out there haveHere is my code (My actual code is much more involved than this, but for testing purposes, I extracted the following code and stuck it in a new project to isolate my problem):
protected void Page_Init(object sender, EventArgs e)
{
if (!IsPostBack)

Forms Data Controls :: Update Gridview Command With Customized Parameters?
Mar 22, 2011I have a asp.net gridview control on my page with several fields and a couple of command fields. However, the update command is giving me problems.
Here is what works. The update command works provided I put straight text into the textboxes that appear. I even have one field that contains a dropdown list which works fine.
Here's the problem. I have two fields that need to access their value programmatically. These fields will reflect the current datetime and the current loggedin user from active directory. I have already created public strings in the C# code.
When I run the edit command on the asp form the grid uses one "DataKeyNames" element. With this the grid can update the selectedrow. However, I haven't been able to access it programmatically in the C# code. I can access the selectedrow in the "selectedindexchanged" event but then I am not able to update my fields in the gridview itself. So, part one of my question is how to I access the "DataKeyNames" properties of a gridview control.
if I can't access the "DataKeyName" property perhaps I could set the label nested within the gridview to the "myCurrentUser()" public string. I am inserting my code to hopefully make this clearer.
Forms Data Controls :: Gridview Readonly Colums?

View 6 RepliesForms Data Controls :: GridView Update And Delete Command Button Does Not Trigger
Apr 3, 2010I have 3 gridviews in one of my web page, each of which will display different data based on the typeid. I have simplified the system structure in the image below(further description will be stated below the image):
As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews.
During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.

However, the Update(command button) and Delete(template field) doesn't work,the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource.

Forms Data Controls :: Insidious Bug Found For A Bound Gridview With UPDATE Command?
Feb 17, 2010Bug: UPDATE command Does NOT Work as Expected on a DataBound GridView This was tested in VS2005 and VS2008
Took a while to figure this out - A simple recurse thru Page Controls Makes UPDATE Not Work as expected.
To Recreate this bug:
A simple Gridview bound to an Objectdatasource on a page with ALLOWEDIT ALLOWDELETE
If one inserts some code (a function call in my example) that just recurses the PAGE controls in either the PAGE_PREINIT, PAGE_INIT, PAGE_INITCOMPLETE events,
Then the UPDATE does not FIRE! and After Pressing UPDATE the GRID does not BIND! You Get A Blank Page - Funny thing tought it's only the UPDATE Functionality that gets affected by this - Everything else works fine including EDIT & DELETE.
If the same function call (recurse thru page controls) is added in the PAGE_PRELOAD, PAGE_LOAD -- Then the UPDATE starts working again as expected.
BELOW Is SAMPLE Code using the NORTHWIND DB Products Table and a Typed DATASET.XSD - You can use your own datasource for the ObjectDatasource - (Note I took out the Foreingkey constraint in products table from Nortwind for delete to work)
NOTE: One should be able to just cut and paste the function PAGECONTROLS_RECURSETEST on any working form that has a bound Gridview with Update functionality and you should be able recreate the bug that way by calling the function from the different page_events

Event Handler - Obtain Selected Data From GridView Control
Jan 26, 2016I use this code to obtain a selected data from GridView control. I created a user control and reference it to ASPX page. However, for some reason I can not access public methods IndexChanged to retrieve information of selected line.
*
User controls:
*
Public gridRow As GridViewRow
Public Event IndexChanged As GridViewSelectEventHandler
*
Protected Sub GridView_SelectedIndexChanged (sender As Object, e As EventArgs) Handles gv.SelectedIndexChanged
******* gridRow = Grid.SelectedRow
******* RaiseEvent IndexChanged (sender, e)
End Sub
*
ASPX page:
*
*
grid.IndexChanged - there is no such event in the selection (the grid is the name of the user control)
