I want to refresh my asp.net page after someone clicks an "Add" button. However, the "Add" button is part of user control inside another user control and the child control and parent control are both wrapped in Update Panels: Code below is cut short for display, there's a reason the user control is inside another user control
Inside first control:

I have a page and on that page i have a button and a user control. I want to refresh the user control without refreshing the page.
I know i cannot do it otherwise so i did is...
(wrapped my user control inside the Update Panel.)
<asp:TextBox ID="txtName" runat="server"></asp:TextBox><br />
<asp:Button ID="btnAdd" runat="server" Text="Add name to list" OnClick="btnAdd_Click" /><br /><br />
<asp:UpdatePanel ID="upShowNames" runat="server">
<ContentTemplate>
<uc1:ShowNames ID="ucShowNames" runat="server" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnAdd" />
</Triggers>
</asp:UpdatePanel>
but i still the control wont refresh. i also tried calling the update panels .Update() method by changing its UpdateMode to Conditional but that does not work either...does any one know how can we do it then..
I have a label control. I added table dynamically into the label. and dynamically buttons into table cells. On button click of each cell raises a popup where I can add a item. Now I have a problem, My table is not refreshing when I added the items and closed the popup. But they are adding on the next event raise.

I am having problems finding my UserControls inside the Controls collection of a Placeholder control.
I have a ListView control with a PlaceHolder control in its ItemTemplate. OnItemdataBound for the ListView control I am adding a custom UserControl to the Controls collection of the Placeholder control. It all renders fine. My problem is when I try to find my user controls in the Placeholder. I just can't get it back. My code is below.
My objective here is to get to the input controls within my UserControl and call the save method of this.
PlaceHolder intakeBenefitHolder = null;
protected void lvIntakeBenefits_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
using (ListViewDataItem item = (ListViewDataItem)e.Item)

1)How I can read a value of a text control in javascript on the usercontrol ?
2)also how I can assing a value of a control to another control via javascript function .
Part of a web application we have uses an in-house web control assembly. This assembly contains several web user controls where several of these are used by other web controls within the same assembly.
The assembly is built as a website with a web deployment project.
The main web application's pages are dynamically compiled through a service into a single assembly and placed into the appropriate bin folder. In our development server the old assemblies aren't always tidied up and removed, meaning the folder gets full of old assemblies.
When the page that uses the in-house web control assembly (mentioned above) runs, the asp.net instance throws an out of memory as it loads all the old assemblies in an attempt to determine which assembly houses the reference to the user control being used by the other user control inside the same assembly.
We've been using the following inside the top level user controls to register the other controls
<%@ Register Src="~/....ascx" TagPrefix="UC" TagName="...." %>
Of course when the application runs this gives no information as to which assembly it can find it in.
Is there anyone that's come across this problem before? It's not really a problem as our live servers use a clean up tool to remove old assemblies, but there are still potential situations where we could get out of memory caused by this (for example the tool stops working!), so it would be nice to resolve this problem.
Here is the stack trace

I got 15 tabs and 15 user controls assigned to each tab.All are loading at once which id delaying the process.
I want to load one user control on selection of a tab in tab container.
I'm doing a menu that loads levels dynamicly, when you click on a item the next level is loaded asynchronously. For each menu item I have a user control. Every user control is declared in its parent, for example, the "secondlevelcontrol" has the reference to "thirdlevelcontrol".With this level of nesting, I want to manage the asynchronous calls on every user control so, when the first level is loaded the javascript to load the second is loaded too. When the second level is loaded the javascript to load the third is loaded too.
To do asynchronous calls I'm implementing ICallbackEventHandler interface. As you can see in the examples, controls are added to the page as plain html. The method "ProcessOnLoadEvent" executes all lines of the "OnLoad" event of the user control.An example of the implementation is this for the user control of fourth level:
public string GetCallbackResult()
{
return _callbackRendering;
}

I am looking at somebody else's code and in it there is a user control:
<UserControl:Comments ID="Comments1" runat="server" ObjectID="4" ObjectRecordID='<%#((Alert)Container.DataItem).AlertId %>'></UserControl:Comments>
What I don't quite understand is how the value for ObjectRecordID gets assigned. I
understand by looking at the code that AlerId is getting assigned to ObjectRecordID
but how is ((Alert)Container.DataItem).AlertId grabbing its value?
I'm in the process of converting an ASP.Net webform into a User control and there an event that now says
no suitable method found to override
the event code causing the compile error
protected override void OnPreInit(EventArgs e)
{
//do some stuff
base.OnPreInit(e);
}
Is there any equivalent for a user control?
I have a requirement where a user logs on to a server where exists a website. The user bring up the site on a browser on that server and loads a power point presentation slide. At that time, users using their laptop clicks on the link to that site and sees that particular PPT slide loaded on the server. Then the operator/user on the server clicks on the second slide and the laptop would now see the second slide. Is this possible to do? If yes, then what technology to use? DHTML? or something else.

View 5 RepliesI have a page with lots of panels on it. Some of the panels are user controls and some are just on the page. I have a form on the page where you can add users and a gridview which is a user control showing a list of users.When a new user is added on the form I want to do gridview.databind() for the gridview in the user control. Does anyone know how to do this?
View 3 RepliesI have written a user control that captures some user input and has a Save button to save it to the DB. I use a repeater to render a number of these controls on the page - imagine a list of multiple choice questions with a Save button by each question.
I am loading the user control inside the repeater's ItemDataBound event like this (code simplified):
[code]....
The problem is that when the Save button is clicked, the page posts back, but lbnUpdate_Click is not called. The Page_Load event of the page itself is called however.
I should mention that the repeater is part of a user control, and that user control is loaded inside another user control (this is a DotNetNuke site which makes heavy use of user controls). The Save button link looks like this:
javascript:__doPostBack('dnn$ctr498$AssignmentsList$rptAssignments$ctl04$ctl00$lbnUpdate','')
I'm trying to find a TextBox in the code-behind page, it's inside a nested master page and also then inside another control container (it's inside ctrlCheckoutShippingAddress also) .

I am writing an ASP.NET custom control.In my custom control code, I find a PlaceHolder control in the page like so:this.myPlaceholder = Page.FindControl("placeholder1") as PlaceHolder Then, I render the placeholder as the output of the custom control:
protected override void Render(HtmlTextWriter output)
if (this.myPlaceholder != null)
this.myPlaceholder.RenderControl(output);
However, this causes the placeholder to be rendered in two places - in the custom control output (good) and in the original location in the page (bad).
I am trying to set the active view in a multiview control from a different page using a linkbutton control. It does not seem to work for me.

I 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 have a Web Site project, and within it I have a user Web Control defined in an ascx file.The control is added to the Site.Master, and it shows up correctly on the page and everything is fine.I need to override some of the control's fields on one of the pages that derive from Site.Master.
// In OnLoad:
MyControlName control = (MyControlName) Page.Master.GetBaseMasterPage().FindControl("controlID"));
The issue is that MyControlName doesn't register as a valid Type on the child page. If I add a second instance of the control to the child page directly, the above works as needed, but if the control isn't placed directly on the page, and instead is only defined in the master page, the type is undefined. The control is not in a namespace, and is defined within the project, so I don't know why it is having such an issue location the appropriate type.If I put a breakpoint in the OnLoad, the type listed for the control is ASP.my_control_name_ascx, but using that does not work either. Why can't the child class reference the correct type? Can I fix this?
how can i store a whole page in view state and retrieve each control usiing view state findcontrol on

In my default.aspx page I have a PlaceHolder control within an UpdatePanel. In this placeholder control I will dynamically load a web user control, which is just a form with a submit button. On this user control, I have the form within an update panel and I have the "Submit" button's Click Event added to the triggers.
When I submit the form, the UpdatePanel on the web user control nor the update panel on the default.aspx page are capturing the post back, thus causing a full post back which refreshes my page.
how to capture this post so its rendered in Ajax and not a full post back?
I have on dropdown that show hide user control. In the user control i have Ok and Cancel button.
When the dropdown change i want to apply ValidationGroup on the Ok button that is inside UserControl.
I have a label on my master page (called mainMenu) that shows the number of items in a cart. The label wasn't getting updated when the cart was cleared until after an additional postback or redirect so I created a method on the master page called UpdateNumberOfItemsInCart to update the label text.
Using the MasterType directive on the Cart page allowing me to strongly type the master page, I can access the update method from the Cart page. There is a user control also named Cart that actually contains the 'clear cart' button so I setup an event on the user control also called UpdateNumberOfItemsInCart. I wire up the Cart control's event on the Cart page which then makes a call to Master.UpdateNumberOfItemsInCart();
So far so good except when I wrap the Cart control with an update panel the update to the cart count label doesn't happen.

Im wondering how to get a label control that is in a header template in a datalist on an aspx page. I need the control text to change when the user checks a checkbox outside of the list on the page somewhere. I tried Itemdatabound, but I dont want to have to rebind the list everytime the user checks the box (lots of slow reaction time)
