I wish to access a user control's public property from another user control. But, I am not able to access one user control within another. Even after using the namespace 'ASP', I am only able to see the reference to the current user control. However, in a page I am able to refer to all the user controls with the ASP namespace. Am I missing something or it needs to be that way?
Update:
Here the exact scenario - I have two user controls A and B. Now both of them are being used on a Page Default.aspx. There is a public proprty on control A which holds the name of the control clicked within A. I wish to access this property in control B to make some decisions. With the suggestions gioven by you, I understand reaching to the control by FindControl method of the container page, but how do I cast it to control A to fetch the property value when I cannot get the reference of the control A in B?
I have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
[Code]....
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.

What is the best possible way to achieve this scenario.
how to call a function of user control from the parent page?
I have a user control inside of default.aspx page, And I have a function in the code behind of user control. I need to call that function from a code behind of default.aspx
Can i bind and call the user control directly on click event of link button? instead of binding user control in another aspx page and then call it to the masterpage's link button click?
or else can i bind user control in a page lets say default.aspx and then call it in two different master page and show different functionality of it according to the masterpage its getting shown?
For an Umbraco project, I am trying to make a simple Ajax call.. I can't use PageMethods because I need to make the call from inside a UserControl.. I tried to do it via web service call like this:
Web service method:
[System.Web.Script.Services.ScriptService] public class MapService : System.Web.Services.WebService { [WebMethod]
[Code]...
The problem is, "MapService.GetCities" method doesn't get invoked..
What might be the problem here?
Alternatively, what is there any better way to make these kind of Ajax calls in a User Control?
I have a dynamically created address user control (on a customer administration screen) that is created through the use of a place holder. A customer can have multiple addresses, so they dynamically dropped onto the page.
I have got this far, but now I need to be able to save the updated addresses for the customer but I can't get any event to fire on the user controls. When I check to see run plhAddress.HasControls() it returns false?
The way I am generating the user controls is as follows.. private UserControl LoadControl(string UserControlPath, params object[] constructorParameters)
I have one user control which has 2 gridview first grid has columns (GroupName, Description, chkRemove checkbox) another gridview has columns (GroupName, Description, chkAdd), apart from that i dont have any code on .cs file of usercontrol.
I want to call same user control on 4 aspx pages and datagrid binding, sorting, paging and search functionality i want to do on respective aspx.cs pages not on user control where i am calling this uercontrol because for every aspx page field name is same but when i am binding the data to the grid that logic is different.
For first aspx page i called my usercontrol like this and everything is working fine: -
I have user control. Inside that have some buttons. my page has gridview . I want check grid view rows from user control button. User control is my menu. My grid has column with radio button.
When i click button of user control i want load item page which data which gridview radio button cheked true.
There are two user controls, which are built dynamically.
In the first control, I am adding a link button, and trying to attach a click event on the same. But the event is not fired.
Actually the main goal is, when the link is clicked, based on which one is clicked, I need to show second control (the values on the new controls are based on the first controls link button that is clicked).
If I use javascript, I will need to use ActiveX or is there any other way to instantiate the second control using javascript
I have created a user control and am ready to convert it into a custom control. I am trying to follow:
[URL] the steps mentioned in the link.
I am not seeing Build / Publish Web Site option.
I am using VS 2008. I only see Publish User Control but it doesn't give all the settings mentioned below. When I do publish user control, it just copies the ascx file to the desired location. how can I convert the user control to custom control.
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.
I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
I'm not able to call a service using the scriptmanager and javascript. But when I include the service into the project i call it. but when i seperate it in another project. I'm not able to call.
