I want to use Javascript Alert to show errors and warnings to my users so I wrote a method for this purpose which is part of a class. The code is as follows:
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.
[Code]....
[Code]....
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.
I added 'Imports System.Web.UI' to the code behind for a user control so that I could dynamically create JavaScript usingClientScript.RegisterClientScriptBlock. However when I declared the variable, I got the following error message'System.Web.UI.ClientScriptManager.Friend Sub New(owner As System.Web.UI.Page)' is not accessible in this context because it is 'Friend'.
I am new to .Net and webpart. What I try to do is to create a griedview webpart with a functionality of export to excel. The gridview also can drildown another gridview. The drilldown work as expected. When click export to excel link button it works ok, too. The problem is when comeing back to the gridview to click any row, it stops to drilldown. If I want to use export to excel link it stop working also. Only refresh page can make it work again. I did research and found a solution, that is, to implement a javascript to solve the problem. I follow references from microsoft site as shown below.
Looking at the blogs on using the Register.ClientScript for a javascript file, it wasn't obvious where the best place is to put it. Do you put it in the HTML file , do you put it in codebehind in the Page_Load subroutine
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 have aspx page where there is no code behind. Server side Code written inside tag with runat server attribute.
ClientScript.RegisterClientScriptBlock(this.GetType(), "Email", "GetEmail();"); in page_load() event, it just print GetEmail(); when page load html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript" language="javascript"> function GetEmail() [code]...
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 m using web user control for java script calendar when i use ScriptManager on aspx page then value of calendar input type is not showing without ScriptManager is showing..
I m using this code on Test.aspx page -
<uc1:CalendarUserControl ID="CalendarUserControl1" runat="server" OnLoad="CalendarUserControl1_Load"/> And I m using code on CalendarUserControl.ascx- <input type="text" name="showdia" id="showdia" size="9"/><input onclick="return showCalendar('showdia', 'mm/dd/yyyy');" type="image" src="images/cal.gif" name="reset" style="cursor:pointer"/> <input id="Button1" type="button" onclick="loadimages(showdia.value)" style="background-image: url(images/language/english/view.gif); width: 57px; height: 24px; background-color: transparent;"/> And code on Test.aspx.cs file - protected void Page_Load(object sender, EventArgs e) { string myscript1 = "document.getElementById('showdia').value='" + System.DateTime.Now.ToString("d") + "'"; ClientScript.RegisterStartupScript(typeof(Test.aspx), "myscript1", myscript1, true); } when I use ScriptManager then value of <input type="text" name="showdia" id="showdia" /> is not showing
I use AlwaysVisibleControl in a page and show a result of data access in popup with ClientScript(or
ScriptManager). RegisterStartupScript. ScriptManager.RegisterStartupScript(this, this.GetType(), "error", "<script language=javascript> alert('* Saved well.');</script>", true); When popup window appears after postback, alwaysvisiblecontrol is on wrong location. (Initial html coded place not the alwaysvisible targeted place) After I click OK button of poput, alwaysvisiblecontrol locates at target place. I want this popup locates target place before popup window popups up.
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.
[Code]....
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).
if anyone has encountered this before and knows a way to work around it? The app is ASP.NET 3.5. Some of the markup on the page in question is wrapped in an UpdatePanel, including a checkbox. The checkbox is set to AutoPostBack. When the CheckedChanged event fires, information is gathered from screen elements and dropped into a stringbuilder that becomes part of a window.open javascript that is called from this ClientScript block:
[Code]....
I put in a breakpoint and followed the execution. No errors but the javascript doesn't open the new window. Comment out the UpdatePanel and the javascript executes and the window pops up like it should. Has anyone encountered this before? Is there a way to make the UpdatePanel play nice and let the javascript execute?
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:

At a bit of a loss here. As the subject says, I have a repeater control that uses the variable xmlN which is declared in my Sub Page_Load. Posted code below.
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: BC30451: Name 'txtUser' is not declared.
I have a Master file and an .aspx page which makes use of the Master file. I am currently working through implementing a new feature (see [URL] if interested), but essentially the problem has arisen after added Javascript code to my Main.Master page. Whenever there is a <%= %> in the Javascript code pointing to an object in the .aspx page, an new compilation error occurs:
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.
