I mean, it's easy to add a Button programmactically to an aspx page, but a server control's event handler probably has to be set early in the page life cycle (maybe before Control.Load event). As a result in reality, are dynamic controls rarely added to apsx pages?I wish there is a way to call postback at the server, so that a event is never too late.

I am programatically adding a control to an aspx page and binding a server side event to an index changed event inside the control. (It's a RadListBox from Telerik's ASP.NET controls) The problem is that on the postback triggered from the control, the event doesn't hit its eventhandler because on the postback the control isn't defined. Is there a way to handle this without having to retrace the logic taken before and rebuild the controls so the events that stem from it are processed?
View 1 RepliesI've looked all over for a solution to my problem and i haven't come across a solution that works for me, at least i can't figure out how to make them work for me.I am creating a group of rating controls and adding them to a placeholder. I want to retrieve all ratings and update my database after a button clickall worked wonderfully, i thought i was making some real progress but then i noticed i could not get the value on the server side no matter what i tried... i noticed it's overwriting the value on a postback(i am assuming) i tried adding a if not isPostback statement but then it threw a callback error. anyway here is some code:
Sub Page_Load(sender as object, e as eventArgs) Handles Me.Load
For Each DataRow As Row In DataTable
Dim r As New AjaxControltoolkit.Rating
r.MaxRating = "5"
r.CurrentValue = "0"

In my table I have 3 fields:
[inFrmDate] (this is the key field), [inFrmData], [totFrmData] (this accepts nulls)When I try to add [inFrmDate], [inFrmData] to the GridView I get the messageto the effect that the:
@inFrmDate scalar is not declared.
But as you can see from below it is declared:

I am working on the migration of the server. Our new server is Windows server 2008 with IIS7.0 I have a great difficulty in browsing the pages hosted in virtual directories. I have followed the proper steps of creating a virtual directories and converting them into applications. But when i try to browsing the pages of the virtual directory, i get the 404 error. Note: The .Net Framework 4.0 is installed on the server and the web applications which i am trying to configure in the virtual directories are developed in Visual Studio 3.0. Even the http://localhost also don't work.

I have to maintain a very old application. What I am doing right now is I have a dev machine where I have the solution for the old web app (1.1) usually if i have to add new pages to the app what I used to do is add .aspx pages in the dev mechine and compile the solution generate new dll's and copy the .dlls and .aspx pages to the server used to work fine.
Now I needed to add a page. I did the same thing some how the server is not reconizing the new page I have created. what Should i do to make the server recognize the new page?
I did IISRESET it did n't work.
I have a div runing on server in which i programmatically add images. On post back, id like to get some attributtes from those images, but they are nowhere to be found. What am i doing wrong?

I have hosted my project in the remote server. i pasted all the dlls & all the necessary files into inetpub->wwwroot ->httpdocs->(pasted all files). In the server we have .net framework 3.5 and IIS 6.0
Now I just want to check whether my files are running locally on the server. So I did the following. Just opened the IIS, made the httpdocs folder as a virtual directory. And then I clicked the httpdocs.It displayed all the files it has in the right side pane. Then I right clicked the default.aspx and then I clicked browse. Now the browser opened with the URL http://localhost/httpdocs/default.aspx. But I could not able to see the aspx page.It just shows "The page is not found"
But when I tried the same steps for opening a .html page it works fine (http://localhost/httpdocs/test.html) I can able to view the html pages.
Whether I need to configure anything on the IIS.... What should I do to view the .aspx files
I am a total novice to VB so bear with me.In my web-based project, I pass an ID field as a parameter in my URL and go through each row in my gridview to find the correct row that matches the ID parameter, like so:
[Code]....
[Code]....
The problem is that this code only works if the corresponding ID is in a row displayed on the first page. I want to loop through each page in the gridview's rows until either the correct ID is found or it reaches the end of the data set. How do I do this? I assume I need another For loop that looks something like...
[Code]....
...that will go right before my other for loop, and one will loop through each page in the gridview. But obviously I've got that For Loop completely wrong. How do I do this correctly?

I wrote a test page that does a bunch of busy work in a method called at page load. This process as I have it now takes around 12 seconds.
If I try to load another page while the first long running page is loading, this second page doing nothing except writing out a world, it doesn't load until the first long running page is finished.
Why is this the case? I would think IIS would be able to handle multiple concurrent connections, it seems crazy that one long running page would stop every other page in the application from loading. I must be missing something or not understand how IIS works.
I would think multiple independent requests would be spawned on different threads. Is this only the case if the requests are from different sessions entirely? Are all requests from a single session bound to a single thread?

i want to save user's doc,docx file in database and show the uploaded user doc ,docx file in asp page
I have 2 user controls that is hosted by 2 different aspx pages.
example:
srcpage.aspx --> hosts the --> sourceusercontrol.ascx
and
destpage.aspx --> hosts the --> destinationusercontrol.ascx
I would like the values in the text fields of the sourceusercontrol.ascx to be passed on to the labels in the destinationusercontrol.ascx.
I have gone through the MSDN ASP.Net examples and i was able to successfully pass values between two aspx page using the postback URL functionality, but cannot do the same thing with the usercontrols on 2 different aspx pages.
I have an asp page "A" and I've created a user control "B"
When I do A.Controls.Add(B), I would like to make an element, say a TableRow which is defined inside control "B", invisible via code behind.
When looking through Controls of "A", I cannot seem to find that table row.
I've created a wallboard application to display outstanding support calls for my ICT department. I've bound a number of gridviews to sqldatasources which execute a stored procedure. This is automated via asp.net ajax controls and partially refreshes the page/data every 30 seconds.
At the moment, when the number of records in the gridview goes over 9, the gridview automatically pages and shows the number of pages in the bottom right hand corner. The helpdesk can then VNC to the box which controls the screen and manually click to see what's on the next page.
What I am after is a way to programmatically (using the c# code-behind file) changing the current displayed page after 10/15 seconds or so, obviously if this is possible in the scope of the gridview. I trailed using javascript (and failed at jquery) of scrolling the gridview within a div, however this didn't work as expected.
Can anyone point me in the right example. I can't find anyone else querying this functionality via a quick Google.
Gridview Code:
<asp:GridView ID="GridView1" ShowHeader="False" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"
GridLines="None" CellPadding="2" Font-Size="35pt" AllowPaging="True" PageSize="9">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" SortExpression="ID">
<ItemStyle Width="15%" />
</asp:BoundField>
<asp:BoundField DataField="ASSIGNEES" HeaderText="ASSIGNEES" SortExpression="ASSIGNEES">
<ItemStyle Width="32%" Wrap="false"/>
</asp:BoundField>
<asp:BoundField DataField="title" HeaderText="title" SortExpression="title">
<ItemStyle Width="53%" Wrap="false"/>
</asp:BoundField>
</Columns>
</asp:GridView>
SqlDataSource Code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FPConnectionString %>" SelectCommand="HDMonitoringOutstandingToday" SelectCommandType="StoredProcedure"></asp:SqlDataSource>

.NET 4.0 has been installed on the server, and is selected for the project. All of this, and I still get HTTP Error 404 -
If I drag a control from the toolbox in Visual Studio (2008+SP1) into an ASPX page I get a proposal for an ID: <asp:Button ID="Button1" runat="server" Text="Button" /> That's nice and helps not to forget to assign an ID. Most of the time I rename the ID like: <asp:Button ID="MySpecialButtonForSpecialTask1" runat="server" Text="Button" />
Now I have a task 2 (3, 4, ..., n) and need a button "MySpecialButtonForSpecialTask2". So I copy and paste the first one with ID="MySpecialButtonForSpecialTask1". That's the result: <asp:Button ID="Button1" runat="server" Text="Button" /> That's not nice since I need to change now "Button1" to "MySpecialButtonForSpecialTask2" but I would prefer to change "MySpecialButtonForSpecialTask1" to "MySpecialButtonForSpecialTask2". Is there any setting or trick in VS to prevent assigning new IDs after copy and paste?
I'm not looking for the option "Tools > Options > Text Editor > HTML> Miscellaneous > Auto ID elements on paste in Source view" since it also turns off creating IDs for controls inserted from the toolbox. I only would like to switch off this when copy & paste.
I need to programmatically parse and transform ASP.NET webform pages. It's a requirement that I have =(.
Anyone know any tools or frameworks?

Apropos MSDN link: [URL] [.NET Framework 4 - ASP.NET] Implementing Client Callbacks Programmatically Without Postbacks in ASP.NET Web Pages Using the code from the above link in the following code snippet, if you keep a break point on the statement "if (IsPostBack)" in the Page_Load event. The control moves into the "if (IsPostBack)" block after the alert, which mean that it is a Postback. Then, how come you say "...Without Postbacks"? I am getting confused here.
