.net - ModalPopupExtender + ASP.NET AJAX: Can't Page Grid
Mar 30, 2010
I'm trying to page and sort my DataGrid which is inside a ModalPopupExtender but I can't page it in any way, already tried with <Triggers>, put the UpdatePanel inside, outside, in the middle, and it does NOT work. Modal popup does not get closed but the grid just disappears. Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
BindData()
End If

I have more than 30,000 rows in a table. It takes a lot of time to load all the data in the gridview. So I want to display 100 rows at a time. When I click next page button, another 100 rows should be displayed. When I click previous page button, previous 100 rows should be displayed. If I type page 5 in a text box, then I want to jump over to the 5th lot of rows.
I also want to display how many pages there will be. Can we implement this concept in vb.net [winform] gridview. I am using database PostgreSQL.

For several days now I've been messing around with Ajax calls using different combinations of javascript, ASP controls, and regular controls. I've gotten a bit of understanding about what's going on, but using ASP controls still hides too much of the machinery, and I want to have a deeper understanding. With that aim, can anyone tell me why the following setup doesn't quite work?I have a file "Testy.aspx" with the following:[code].....
So, I hoped to make my .aspx file do double-duty both as the regular-page request handler as well as the Ajax request handler. However, when I click the button ("baroo") to generate the Ajax request, the result that ends up written back to the "testytext" div is the raw html for the entire page, as if under normal request conditions. Clearly, my attempt to override the page request by making the code-behind implement IHttpHandler and supplying an "Overrides Sub ProcessRequest" method is not working. The server is still treating the Ajax request as a normal request, and in fact my own "ProcessRequest" method is never even called.Is it possible to build a page/handler like this? How can I intercept the incoming request from the client and respond accordingly?This is how Ajax works, right? So it must be possible.Again, I'm deliberately doing this as an excercise to avoid the use of "magic" ASP controls like UpdatePanels,

I'm not sure what's wrong with the following setup. I have a View that lists a number of records, and each has a dropdown associated with it to change a value on that record. I had it all working without AJAX, but you had to change a bunch of the dropdowns then click a Submit button. I wanted to change it so that it would save the dropdown choice immediately.
My stripped down View (of type IEnumerable(Of MyTable)):
<script src="../../Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script>
[Code]....
What I would like to happen is for the dropdown change to trigger the Update controller, but probably not return anything - just update the database and let the user move on. What's happening though is that a blank page is displayed with the Content value on it (i.e. "123: ABC"). It's the correct id/code combo, so the Update seems to be firing correctly, it's just choosing to wipe out the html.

I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout.
Here is my code:
<div id="divFileInputs" runat="server">
<input id="file1" name="fileInput" type="file" runat="server" size="50" style="width: 50em"
onfocus="AddFileInput()" class="textbox" /></div>
[code]....
When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded.

I'm trying to call a modal popup extender from javascript. Here's the call:
function MyFunction()
{alert("test");
$find('mdlPassword').show;}
I get the alert when it's called, but the modal popup extender won't show. Here's the aspx stuff:
<!-- Popup Extenders Should Go Here -->
<asp:button id="Button1" runat="server" text="Button" style="display: none;" />
<asp:ModalPopupExtender ID="mdlPassword" runat="server"

I am using the ModalPopupExtender control to display a modal popup dialog when a button is click. The problem is that dragging the dialog results in an 'scrollleft is null or not an object' error. Here's a video demo and here is ALL the code: If possible, I'd like to resolve this problem w/o resorting to modifying the AjaxToolkit scripts themselves.

winforms .net 3.5 Ultrawingrid 9.2 In my subclass of Ultrawingrid.Ultragrid :
[Code]...
This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?
