I want to know that in any data controls like gridview or form view or details view there is two events
1. GridView1_RowUpdating()
2. GridView1_RowUpdated()
What the difference between them and which is better ?
After i click edit, i will get Update and Cancel buttonWhen I viewsource, I get this
<input type="submit" name="GridView1$ctl07$ctl01" value="Update"
onclick="javascript:WebForm_DoPostBackWithOptions( new
WebForm_PostBackOptions("GridView1$ctl07$ctl0 1",
[code]...

View 2 RepliesI have a requirement something as below.
1. I will click on the EDIT link in one of the grid view row. The row will change to edit mode
2. I will update the values and click update link in edit mode and edit mode closes.
3. At this point I need to capture the datakey of the updated row into some variable
I've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
View 4 RepliesSeems I can't find a way to get row index (or id) for the row just updated in gridview1_RowUpdated()
(in RowUpdating, I can use: for example:
txtActivityID = CType(gridview1.Rows(e.RowIndex).FindControl("txtActivityID"), TextBox)
)
I am working on object data source and datagridview. I have given object data source to the grid view as the data source of grid. The issue which i m facing is that whenever i click on next page(like 2 or 3 or 1) it takes lot of time to fire. although it is fired but I have to wait a minute or two and then it fired.
Whenever I click any event(e.g. next page , page 5 ,3 or edit etc) of gridview it does not give response. If I wait for a minute then click one of event then it performs, and then again I have to wait to fire other event.
I'm currently facing an annoying problem that i can't seem to figure out. I have a gridview in my page, and i wanted to add a second header row to it. Well, i did that without any problems using the code below.
No problems so far. I then intended to add some filter to my gridview and so added a dropdown list in this second header i had created.
I simply added the control i previously had to my cell of the header.
[Code]....
The problem is that now, the SelectedValueChanged event is not firing when i change the value on my dropdown list. If i place her out of the gridview, the event fires normally, when placed inside the gridview the event apparently stops firing.
I have tried this with and without AutoPostback ON, though the final goal would be to have that option on OFF. (The postback would be caused by some other button on the same second header row, allowing the user to combine multiple filters simultaneosly)
what are the events fired during gridview loading,,,,,,,,,,?
View 1 RepliesIs there a way I ignore all gridviews events (sorting, paginating) when using the back command (history.back)?
For example:
The user is sorting my grid and when he presses the back button or a link with history.back he goes to the previous page, not the previous grid state.
Im not using ajax or update panel, Im not allowed to. It's a regular grid in an aspx.
I would like to display time difference between previous row in GridView.
I prefer creating new Column in SQL, but I can't come up with getting value from "last row" in SQL statement.
The reason is that I would like to have Total hours.
ID | DateTime | Time Difference
1 | 1/1/2010 1:00:00 am |
2 | 1/1/2010 2:00:00 am | 1:00
3 | 1/1/2010 4:00:00 am | 2:00
Total 3:00
I've been reading up on the problems with dynamically created controls and how they have been solved. The posts I have come across are creating the controls in a panel or some other open place. I can't seem to get my checkbox to fire the event from inside a gridview. below is the code behind from inside the GridView PreRender event.
[Code]....
..And the Checked Event..
[Code]....
So after all this, nothing happens. I get the postback flash but my command inside the checked event doesn't fire.I tried putting the dynamic creation of the checkbox in Page Load with no effect.. I think because I can't place the checkbox inside the GridView under page load.
I have a user control called ucTriStateButton. It raises an event when it is clicked, called TriStateButtonClicked. If I put this user control on a page, it works fine. Here is the declaration on the .aspx page:
[Code]....
When the button is clicked the method tsbTest_TriStateButtonClicked executes correctly.
The problem is when I put the user control in template field of a GridView.
[Code]....
There is no way to hook the event handler to the control in Page_Load because I cannot get a reference to tsbMorning. So I did it in the RowDataBound event handler of the GridView, where I also do a bunch of other row-specific stuff. Although this builds and runs, the event is never actually subscribed to and so never gets fired.
So the question is - how can I handle an event from many instances of the same user control within a GridView? I am calling the same bit of code regardless of which user control is actually clicked. I only need to know that one was clicked.

I'm using a standard GridView control inside of a web form. The web form uses a master page. The application is running within sharepoint (wss 3.0) environment. When i attach both the OnRowCommand and OnRowDatabound events to the gridview as shown in the markup below, only the OnRowDataBound event fires. The OnRowCommand never gets hit. When i press a button on a row, it posts back but never hits the onRowCommand event and simply falls through and repaints the page . However if i remove the OnRowDataBound event, the OnRowCommand event starts to fires correctly. I've tried a number of things...1. Hooking up the events in code instead of markup. (inside of PageLoad or PageInit)2. Changing the order in which the events are attached.

View 1 RepliesSo I've got a databound grid view within a UpdatePanel.
the user can change the data within the gridview then click a save button to update the data within the database.

I have a page with 2 Controls, a ListBox and a DropDownList.
In the DropDownList you can select a PLACE.
In the ListBox you can see all DOCUMENTS for the selected PLACE.
If you select a DOCUMENT, the program does a redirect on the selected DOCUMENT.
So, there are an AutoPostBack and an Event (if you select another Item) on both Controls.
The problem is: If I select a PLACE, then I select a DOCUMENT (the pdf document is opened), and then I go back on the page and I want to select another PLACE, the program doesn't select another PLACE, but opens the old DOCUMENT, because there are 2 Events, one to change the PLACE and one to open the DOCUMENTS.
Can I give a priority at the Events?
I am new to asp.net. I need to know the difference between the following 2 methods :
