problem with GridView and PostBack

hi

asp.net 2.0

I have a GridView on a custom web control. This GridView has a Template
field containing among others a ButtonLink. When I click on that link the
data in that row is modified in the database. This field is a counter, it
increasing with 1 each time clicked

Okay, but after I clicked on that buttonlink and made that modification to
the database, I can then click Refresh in the internet browser and the field
in the database is updated again. This is not something I want....

So I went about to place the code inside an if-test:
protected void lbTest_Command( object sender, CommandEventArg s e)
{
if (!Page.IsPostBa ck)
{
//logic here
}
}

But now the code isn't even executed when I click on that button...

any suggestions?

Hi, Jeff

The problem is more basic.

It happens because when you refresh the page the broswer sends another
request to the page, causing another PostBack.

And the click event occurs only during the PostBack event.

Hi group, my setup: I have a GridView that extracts data from my table (a SqlDataSource). For each row, I have an 'edit' button and a 'delete' button. The 'edit' button opens a popup, through which one can insert and edit the table. The 'delete' button deletes the row.

I'm setting the column with for a gridview (25+- columns) and have paging turned on. When the gridview is first displayed, the column widths are all set to the default. But after paging to another page, the widths are set as they should be. Going back to page one, the widths are still correct. Not a clue what's going on here!

Hello, I have a GridView bound to a custom object. I set the DataKeyNames property along with the column DataField properties at design time, and bind the GridView to my object at run-time. In the RowDeleting event, I try to access the DataKeys property, but it contains no elements. This is the first time I'm trying to use DatKeyNames and DataKeys. What am I missing here?

ASP.NET 2.0 I've got problems with the right column in my GridView. The GridView consist of 2 columns, the problem column is the column on the right side. The problem is that it looks like there is a huge space between the 2 columns, see the huge grey space between the 2 columns. I want the columns to be very close to each other with only 10px open space between the columns. Now it looks like there is a 160px margin between them

I'm moving from years with the datagrid to a new project, .net 2.0, using GridView controls. Per past practice, it is often a lot easier to inject controls (or special formatting) in RowDataBound (formerly ItemDataBound) than to mess with complicated templates, especially for things that are consistent across grids or columns. GridView is dumping all the nice stuff put there during a RowDataBound event. Ex: those "!" icons in outlook or...

I have unbound checkboxes in a nested gridview to allow multi-selection of "child" rows.

Everything displays properly, including the checkboxes for each child row (each...

I have a problem at the moment with a web project. I have two Panels within an UpdatePanel on an aspx page (using Masterpages). I'm using ASP.Net 2.0 with an AJAX enabled website.

It seems that a gridview allows us to delete only a single row at a time. How to extend this functionality to select multiple rows and delete all of the selected rows in a single stroke? just like what hotmail web UI is doing now (having the option of selecting multiple rows (using the checkbox provided) and perform a set of operations on them)

Hello, I have a Gridview control (.net 2.0) that I'm having trouble getting the Update button to fire any kind of event or preforming the update. The datatable is based on a join so I don't know if that's what's causing the behavior or not. It seems like the Update button should at least do something. When the Edit button is clicked, the grid goes into Edit mode and the Cancel button takes the grid out of Edit mode. So, I don't get what...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
