i'm trying to develop a ASP.Net control. If it based on System.Web.UI.Control id doesn't work correctly with Ajax.Net updatePanel. If I change it to System.Web.UI.WebControls.WebControl the it works fine with Ajax controls. What is the difference between them and how I implement it on Control based Control?
View 2 RepliesI have a .aspx page in c#. There is an ajax control that shows the data company names from the xml file when the city is selected.
There is also a bing search control on the page.
The issue is that the Ajax control stops populating the data when the search control is present on the page.
The ajax control works absolutely fine when the search control is removed
I am attempting to show/hide a control (txtInpatientType) when a user views individual records on a FormView (frmData) depending on the value stored in another control (txtPatientType). For example, if txtPatientType.Text = "Inpatient" then txtInpatientType.Visible needs to be True. Very simple code follows.

txtPatietType and txtInpatientType are both ReadOnly. txtInpatientType.Visible = false by default.
I have a webdayview control (Infragistics proprietary ASP.net control) on my page. On the aspx source I've inserted some javascript (webdayview_click - clientside click event) that calls a webmethod in the codebehind. This seems to work fine, but when I
insert this webdayview control into a user control and move the corresponding javascript into the aspx of the user control, it doesn't work. I can't even insert a breakpoint into the javascript function to debug it. Is there a way to make it work? I want to enable the click event of the webdayview control so that when I click on it, the javascript function calls the webmethod. Here's my code (remember it is inside a user control):

I posted this question on the Infragistics forum but didn't get any replies. Hopefully I'll get some here. :)
What I'm trying to do is take an instance of a control, and figure out what the markup would look like based on the property values set in the code behind. We've built a web-based web form designer. At the end of the design process we save the markup. For simple controls with supported types, generating the markup was easy. For complex controls with nested properties or unsupported types, we're faced with creating a custom markup generator for each custom control. I was hoping to find info out there that would jump start this development effort.
In simple terms, I have this:
Dim Ctl as Control = CType(Asm.CreateInstance("MyNameSpace.MyControl"), Control)
Ctl.Name = "Name of my control"
And I want to end up with this:
<cc1:MyControl ID="MyControl1" runat="server" Name="Name of my control" />
I have a datagrid view, in that I have a templete column ,inside that I have Image control and label control.

i am using VS2008, 3.5 .net and have installed ajax control toolkit and added controls into toolbox, that was fine. But, i can't get any of control to work, nor it renders in design view on my page. Control source is created, page builds without errors but controls don't work. For example:
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
Below is House_info table
id name behcode
1 Neda 1111
2 Jack 2222

2 iron 1111
3 scarf 2222
and below is SP
ALTER procedure [dbo].[storeinfo1]
@Behcode nvarchar(10)
as
begin
select behcode,Name
,(select Behcode from House_p where BehCode=@Behcode) behcodeP
from House_Info
where BehCode=@Behcode
end
I have image=>Productimage in product.aspx page I want if in House_p table there be my users behcode it do Productimage.visible=true
i.e
In House_info table exist user Sara with behcode=3333 her behcode isn't in House_p table so I want in product.aspx page ProductImage.visible=true
How I can do it?
I'm using the following function (found on this forum) to display a popup control from the server-side:
on the server:
ScriptManager.RegisterStartupScript(this, GetType(), "userInfoPopScript",
string.Format("showPopup('{0}', 2);", targetControlClientId)
, true);
on the client:
[code]....
this works great for explorer 8 , firefox, chrome but on explorer 7 my page just jumps to the left and doesn't show the popup at all.
If I remove the set__parentElementID call, then the popup is displayed but in the wrong position (of course).
Absolute positioning doesnt work for label control in asp.net ajax web form I have tried in VS 2008 as well as Visual Web Developer 2005 as well?

public partial class AjaxUC : System.Web.UI.UserControl { private ITemplate _content = null; [TemplateInstance(TemplateInstance.Single)] [TemplateContainer(typeof(Container))] [PersistenceMode(PersistenceMode.InnerProperty)] public ITemplate Content { get

This control when used on any aspx page will popup the control placed inside the template "divContent" as modalpopup.

I created a .NET user control to work as a DropdownCheckbox and added Jquery to give the sliding and hide effects. The code is as below:

This control works fine in a normal page, but once I put it inside an update panel it doesn't work. Is there a work around or simply I can't use JQuery inside update panel?
If i use signs like ë in the HTML Editor, in IE, its ok, and works. But if i use ë in firefox in the same page with the HTML Editor. If i press safe the ë is converted to: � (copy past doesnt work well, but its a square if you put [] to each other). But how is this possible? And how can i solve this problem? In IE its working well, but 50% of the users of the system i build are using Firefox. So it should work in all editors.

View 5 RepliesWhen using the Telerik ReportViewer control from inside a user control, the control bar (bar with navigation & exports buttons etc) doesn't appear to display correctly. Only the navigation buttons appear in the control bar itself. The other buttons (Export, Refresh, Print, & Close Parameters) all appear below the control bar, each on a new line.
If I do the exact same in a normal page (rather than user contorl), it appears fine.
P.S. I'm using IE 7 and the Telerik 2009 Q3 ASP.NET AJAX suite.

In our company we are building a project, that have maximum flexibility (the boss is not always right, but he is always the boss), by website we are building have a configuration page that can set the type of control(by giving it a name or somthing) the page will create...by example on an email page, we have the "To" field which is a textbox... when the email page is loaded, we have to check how many textboxes are there in the database, and then create the control dynamically when the page loads... what is the best approach for this? is it wise to save the c# code for each control in the database? or just a flag the indicate what type of control i wanna create is enough ?
This may be very simple but I can not figure it out. I am using ASP.Net 3.5/Visual Studio 2010. I have placed a LoginName Control on the page and the login name is properly displaying. I am using forms Authentication and it is set up properly in the web config file. I simply want to insert the logged in username value into the database table so I can track who created the records. I am happy to be able to insert the UserID value. I assume the values are derived out of the aspnet_Users table. Hopefully someone can provide a way to do either. I am not a coder so giving me a quick try this answer won't help me much. I would need to really see the entire solution and code.

I'm migrating the site to a new server running Windows 2008 R2. When I tested the site, I fould that the BetterImage control doesn't work. I use the BetterImage control liberally throughout the site, so this is a real problem for me. I emailed the developer and he responded that I have to change the location in the web.config where I register my custom handlers. How do I do that? And are there any other changes I need to be aware of? How different is the web.config between the two Windows versions?
