im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)
View 5 RepliesThere are 2 UserControls UC1 and UC2, and there is one more class C. I want to share the same instance of c in both UserControls. I know that this can be possible with properties in both UC's and by registering UC2 in UC1 or vice versa. But I want the solution to be loosely coupled. Any best possible way without touching the Actual Page (which hosts UC's)? So i need some best possible way between UCs transfering C.
View 5 RepliesI have 2 usercontrol in my .aspx page.
usercontorl1:
<asp:textbox id="txt" runat="server"></asp:textbox>
<asp:button id="btn" runat="server" text="send" />
usercontrol2:
Here I have gridview control with checkbox for selection of one or two records. Have one button and when clicking this , i need to get the selected records values and assign this values to the textbox which is in usercontrol1.
have a webpage that has a button and 2 userControl placed inside the placeHolder with visible set to false.When run and click on the button, userControl1 will set the visible to true. Now userControl1 is visible and there is also a button inside this userControl1 and when click, will set userControl2 visible to true and hide userControl1. The code below is the code behide for the webpage the do the above task.
[Code]....
Is there a way to do so that when click on the button inside userControl1, is does not show userControl2? I want to do this way is because, the button is for submitting data to database and then will pop up userControl2. When there is an error, only a msgBox will pop up and does not show userControl2.
I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.

I have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.

I've got a situation where there is a page with 3 iframes. The first frame contains a TreeView, the second a GridView which is dependent on the selected node of the Treeview in frame 1 and the third frame contains labels with information also dependent on the TreeView in the first frame.
My problem is, how do I pass information from the first frame to the others? Can I access information about the selected node in JavaScript, pass it to another frame and then do a postback with the info as an argument?
I have MainLayout.master that has UC_Menu.ascx on it.
I have a page named Customer.aspx that uses MainLayout.master. Customer.aspx also contains a UserControl named UC_Details.ascx.
How can I have UC_Menu.ascx call a function that is in UC_Details.ascx with this scenario?
I've seen a few similar examples, but none that match this type of layout.
I want to print some data to my usercontrol, but I dont want to do that from my code behind. In GridViews for example I can use the Eval("Property")-keyword. But in my UserControl I cant to that.
Say that I have a UserContol that have the property;
public string Foo { get; set; }
I want to write this string to my UserControl, I have tried everything:
<%# Eval("Foo") %>
<%$ Eval("Foo") %>
<% Foo %>
etc.
Its very hard to google on my problem since Google ignores my special characters #, $, <% etc.
I'm creating an ASP.NET application that needs to get data from database (time consuming) and show some indication (e.g. gif animation) that the application is doing something. After that the data should be send to user that the user can save or open the CSV file.
I'm able to do this with two button click's. One for getting the data from the database in codebehind and using javascript to show the gif animation for user in the meanwhile. Second to use the esponse.write(myData) and response.end() to send the data for user to save in CSV file.
The problem is that I need to do this with one button click. If I combine the code to one button click handler the data is sent correctly but the gif animation is not hidden because the page is not updated. How to do this correctly with one button click?

View 1 RepliesI think I am not a beginner in asp.net, but now maybe I dont see the solution because it must be so easy..I have a simple Repeater on an UserControl(ascx).After a Postback on a button click I would like loop trough allthe Items from the Repeater, but the RepeaterItem-Collection is Empty!!!!!But NOW it comes, when I move the whole code from the UserControlto the Codebehind of an Page, and move the Repeater also to the Page.It works!!!! The Items-Collection are not empty after the Postback!!!Here is the simple Codebehind from the UserControl:
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
