I have done the following in codebehind of a master page trying to use codebehind to dynamically declare a variable (TextBox1) that exists on my content page. I can't declare it in the html because it is on the content page and unless I am viewing that particular content page, I get an error. So I am trying to create it here when needed.
I don't get an error, but my value for TxtBox1 in the end is "null". I have selected onPreRender to make sure that it is the last thing to take place.
We have an web application which has been working fine on XP but which fails on Windows 7.I have a page where I'm executing several procedures on server-side and then must execute a vbscript function on client-side which I'm registering from my server code.The problem is after postback completed vbScript function is not executed at all.... even a simple "Alert" statement is not executed but only using Windows 7.... same code works fine on windows XP...
I'm using ClientScript.GetPostBackClientHyperlink in the OnRowCreated event of the GridView to postback when you select a row. I put a column of checkboxes in now and when 1 or many checkboxes in the row are selected I don't want the page to postback. I'm having trouble with this.This is my code:
i am facing a strange problem putting it in short .... i have two grids... i have grid1 and grid2... now based on row click of firstgrid..i wd take d id from cell(0) of first grid and then fill up the 2nd grid based on tht info selected (id) from the 1st grid .... here is the code snippet :
and here is the codebehind :
now the problem is that : when i click the row for first time it shows into the 2nd grid all fine ...
Is it possible to use ClientScript.RegisterStartupScript and have it execute immediately after a postback?
I have aspx page where there is no code behind. Server side Code written inside tag with runat server attribute.
The ClientScriptManager seems to require a form with runat=server in order to successfully render scripts. Is everyone just doing this manually, or if dynamic support is required (to avoid registering scripts multiple times), using Placeholders?
I know how to register a client script that is on my web page, but I would like to know how to register my script when the script is in another file. Does anyone know how to register a file containing java script file. This is my code for calling the function when it's in the page.
I created a simple version of what I am trying to do. I have the animation ib a usercontrol that is place in an aspx page. If i click on the button that triggers the animation everything works fine. but what I want is to trigger the animation from ClientScript and I ahve not been able to do that. here is what I have
I use AlwaysVisibleControl in a page and show a result of data access in popup with ClientScript(or
The problem i have noticed is that sometimes after a clientscript alert() the page will not post back properly and kind of "hang". The page will only show the background and will not do anything until the browser is refreshed.
I call clientscripts withing button click events, after the code has succeded or failed(try catch). So i will write to database/upload file/send email and then depending on the restult run a clientscript alert to notify the user. However sometimes after you "Ok" the alert the page does not finish posting back and "hangs" half loaded.
how to fix it? would adding return false; after the alert in the client script at all? (i have seen this in a online code example but they did not explain why they put it there).
Source: <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> Code behind is: Label1.Text = "Thank you for your interest! Your information request is registered on " & Now() & " and will be answered as soon as possible."
When I run the code, I got a error message like this: "Name Label1 is not declared". But the Label1 is filled like in the code behind.What is the problem?
sometimes if i edit my sourcecode i recieve the error that my textbox1 is not declared in my codebehind file. I found only one issue but if i try to solve it i recieve the same error. My issue is that i have to contraols with id=textbox1 so i edit the last one in my apsx site to textbox81 and of course i edit also the codebehind file, but i still have the same error in my VWD2008 I also tried to delete the .net cache files. That is my aspx site(look for textbox1 in the last lines):
I get the above error while compiling and the name is in my .aspx file while i try to assign it in my .vb file like this IN .aspx file:

I am having a button in Update panel. I want to call "ClientScript.RegisterStartupScript" method onClick event of button. when I debug my code. Button onClick Event is fired and also the code is executed.
I am trying to write some code that loads a text box with data from a database every time a page loads. I want to reference the connection as held in the web.config but am struggling to read it. From what I can see I need to use the Configurationmanager.appsettings to read in the connection string but am getting an error:ConfigurationManager.AppSettings("Personal") ConfigurationManager.AppSettings' is not declared or the module containing it is not loaded in the debugging session.
The code is: -
I came across an article that said you need to add a reference to the system.config dll under the .NET tab so did that but it has made no difference. Can anyone tell me how to reference the web.config connection strings in VB?
Compiler Error Message: BC30451: Name 'ModalPopupExtender1' is not declared.
For example, the following is contained in Main.Master:
var modal = $find('<%=ModalPopupExtender1.ClientID%>'); document.getElementById("<%=Image1.ClientID%>").src = imageList[imageIndex];
However, ModalPopupExtender1 and Image1 are contained in Search.aspx.
I have an application which I have worked on several times, but this week I've been trying to get the application to work on a new laptop and failed. First there were was some dependency issues with some controls like the AJAX Control Toolkit and AJAX Extensions, but now that I have everything I'm still getting errors. The errors that I'm getting are only in the App_Code classes. For Example I have the following references in the web.config
When I go to build the page no errors occur, but if I start debugging I get a BC30451: Name is not declared build error, for a label and radio button which are both declared.
The error doesn't show in the error list, and if I press 'Yes' on the 'Would you like to continue and run the last successful build' dialog, I am able to run the most up to date version of the page & debug properly.
