I have a gridview control on my asp.net page(vb.net). I also have a "cancel" button, that when pressed, is supposed to clear the gridview of it's current contents.
However whenever the cancel button is pressed, it just reloads the page and the gridview is still there with the same data that I wanted clear.[code]...

I have a listbox, a textbox, and a button. The button populates the textbox with the selected item & value of the listbox. As below:
Protected Sub GetVariables_Click(ByVal sender As Object, ByVal e As EventArgs) Handles GetVariables.Click

End Sub
The problem I have, is that when doing this it reloads the page each time. Any way around this?

I have a parent page and child page, both aspx. All is working, but now I would like to close child page, if user leaves child popup page and goes back to parent page and clicks on something else like page index of Gridview. I CANNOT close popup child page if user goes to another app, or some other location, I only want to close if something on parent page is changed.
I have the PageIndexChange Event set up for other purposes, I would just like to add some functionality, perhaps a script manager to close the child popup page if the Gridview index is changed, java or another way which ever works best.I think I might also need to check if the child page is even open.

how a gridview in Visual Studio would change a page title on a web page. When the page is first opened, the title is fine. When you start scrolling the grid, the title changes to a number that appears to be the number of pixels moved. Numbers are 0, 14, 28, 42, etc.

View 2 RepliesIs it possible to loop through a gridview with more than one page, the gridview I'm looking at has a pageSize of 20, there are say 26 records (over two pages) and I want to be able to loop though all the records.
For Each row As GridViewRow In GridView.Rows The count of the above is only 20 as the pageSize is set to 20, I can see that the pagecount is 2 but how do you loop through the next page in a gridview? Or would I have to just iterate through the orginal datasource?

I have a gridview and use a session to pass the variables from the page to an edit page. This works perfectly, until you search for a number. When you search the correct record displays in gridview, but when you click edit, it passes the wrong record.
Private Sub gridview1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing
Session("wr_id") = GridView1.Rows(e.NewEditIndex).Cells(2).Text & "~/~" & _
GridView1.Rows(e.NewEditIndex).Cells(3).Text & "~/~" & _
GridView1.Rows(e.NewEditIndex).Cells(4).Text & "~/~" & _
[Code] .....
I realize not all of the code is pasted in here, because it would take too much space. Any Ideas? I'm guessing it has something to do with e.NewEditIndex
Apparently, part of the problem is that while an ASP:GridView has an OnDataBound() event (which you can use in the code-behind), the corresponding HTML table that is produced does NOT, so you can attach that event to JavaScript. (Did I get that right?) So, that's why I'm having trouble with that bit of the issue. Back to the drawing board. I'm a desktop developer (WinForms with VB.NET) transitioning into ASP.NET development. My mind is really bending around the DOM and JavaScript and Session State and all of the stuff that goes along with web development. I'm not stupid, and I've done research (including hours of video watching and hundreds of pages of "Intro to ASP.NET" reading), but I keep hitting the wall with what seem to be fairly straightforward problems.
Basically, my current situation can be summed up as follows:
I have a page that runs a very long process initiated by the user. The long process can take up to a few minutes , so I want to indicate to the user that SOMETHING is happening.When the process has completed, I either have:
a. Results to show in a GridView
b. No results to show
If I have results to show, I want to display them. If I have no results to show, I want to show a label to the user that says "No results to show."

I am currently working with a gridviews in asp.net(vb). I have it where I am able to pass information from gridview1 to gridview2 on the next page. However, what I need to do now is pass a variable from a column in gridview2 to the header of that page. i.e. in Gridview2 we have a column and all results are the same, the column header is StoreName and all the data for column is Sears. I know how to make the entire column invisible, but at the top of the page I need a sentence that looks like this:
Store Information for Sears
I am having trouble with what the code would look like for that line, all the thing I have tried have resulting in using a variable before it is declared. I need this line to be dynamic as the results will not always be for Sears.
I have three dropdown list boxes and a gridview. The gridview shows data based on what is entered in the dropdown list boxes. I have added a button that allows the user to insert a record into the database and then the page refreshes. The problem is that when the page refreshes the gridview goes back to whatever was initially in the dropdown list boxes when I first brought up the page. Is there a way to refresh and maintain the data in the list boxes so the gridview shows the same data? My code is below.

I'm using ASP.net; I have a popup browser window that contains an databound gridview with textboxes. It has an "Add to Order" button which takes the values entered and updates the database, then closes the popup and refreshes the parent. This currently works perfectly using window.opener.document.forms[0].submit();self.close(); in a RegisterScriptBlock
I now need to update the database on gridview page chage so that textbox values are not lost. I put window.opener.document.forms[0].submit(); into the PageIndexChanging event of the datagrid, but it does not refresh the parent window. Refreshing the parent window with the order lines helps the user see what they have already ordered. My update database method runs fine, just not the parent browser refresh. I also tried "window.opener.location.href = window.opener.location.href" to no avail.Refresh parent browser window on GridView page change?
