NET Grid View markup and associated code lets first enumerate the important code pieces of this tutorial.
Data Bind() in Row Editing, I said nothing about what might happen if you removed it. Then set your breakpoints in Row Command, Row Editing, and Row Updating and we'll see what happens. David OK, I'm offically out of bullets, at least for now. If I get some time, I'll see if I can duplicate this, but I'm suspecting there's something out there that neither of us have looked at yet.
I subsequently changed the code behind to explicitly bind to the product table during Row Cancel and Row Edit events.
On Row Data Bound by using `Find Control` will get the dropdown list and then bind it with our Data Table.
Bonus : Now in edit mode we will set gridview dropdown list selected value as it displays before edit mode.
I am confused at this point on why my markup and code behind is not touching the Row Updating event when Update button is clicked. The routine loading of the product table now happens only on the first pass through the code behind.
I also don't understand when I select the grid View control and look at the events in the Properties window of Visual Studio 2010 why I see all the proper event procedures listed for each event I expect to use. Data Bind in the Row Command when the Edit Command is invoked and removed it from Row Editing. The code works as I intended it to (and is listed below).
Now we want to edit the department for selected employee.
So now we added a drop-down list under edit template, which will display only on edit mode. This is a simple task, we made a common function `gv Bind()` which binds our Gridview control with data.
The visitors to a web site can typically be divided into two groups: the users and the administrators.
In data driven web sites, users are normally allowed to view data and administrators are allowed to add, edit or delete data.
By Default, Grid View control displays Item Template which directly shows the Product Name and Unit Price columns but when user clicks Edit button Grid View automatically switches to Edit Item Template and display the control available inside Edit Item Template for user editing.
