View 1 RepliesI'm working on an ASP.net application.I had a problem with a user control I'd designed called LocationSelector. It worked great, but I couldn't use it within an ASP:UpdatePanel. I learned, by browsing SO, that I needed to put my in-line javascript in an external file and register it with ScriptManager so that there are no Response.Write calls in the Javascript.Next, I discovered that the control worked at first, but when I enclosed it within the ASP:UpdatePanel, it would stop functioning after the first AJAX postback. I read that to fix that, I needed to replace my $(document).ready call with function pageLoad() which is automatically executed with each ASP.net page load.
Several of my pages in my ASP.net application work fine (and I was really impressed with how well the framework seemed to drive the application). However, to my dismay, I discovered that my LocationSelector control no longer works at all on three of my pages. The HTML renders, but the pageLoad (which uses jQuery to bind events on control elements) does not fire.I verified this but putting alert('pageLoad'); as the first line of my pageLoad function. On the pages that work, I see the alert. On the pages that don't work, I never see the alert, even on the initial page load.What kind of problem could be causing the pageLoad function on my user control LocationSelector to execute on some pages, but not others?
I have a need to improve the asthetics of the standard buttons .net churns out. I am fully aware of how to do this using css but I can only really style the button if I add a span element inside the button. Luckily the link button allows this so I have got the following which for usability i have put inside a user control.
<linkbutton><label>button text</label></linkbutton>
I have exposed elements so that I can set values from within my aspx.cs page, these are text, command name, command argument, ccc class etc.
As it is a generic control, I have added OnCommand='Button_Click" which fires the event in the control itself. The Button_Click event calls a method ButtonControls passing associated command name and arguments across. ButtonControls uses the name to call the appropriate function.
As these are all very generic buttons, so far so good, but I have a need to trigger button events that may not be generic i.e on a control I have buttons that do something very specific to that control. I also have a requirement to call functions which relate to specific controls on the aspx page. I have created a user control which encapsulates the link button control.
Click triggers > Button_Click > ButtonControls > MethodToCall
sometimes I don't want to call Button_Click just an event on the aspx page itself rather than my generic button handler.
I have a 2 part question for web user controls: 1. I want to have an event fire in my user control, but have it be consumed by the parent page, like:
<asp1:Object id="objectMain" runat="server" OnClick="Click" />
Is it possible to do this? Or do I need to make a server control for this functionality? I have it being able to be set in the Page_Init, but I'd like to make it as similar to actual controls as possible. Also, if it is possible to access via the Events section under Properties, that would be good and 2. I am trying to register the web user control as an AsyncPostbackTrigger for another UpdatePanel. With the previous question in mind, is it also possible to set this via the GUI, or does this need to be set programmatically as well?
I've created a User Control (.ascx), which has a dropdown. When an item is selected, it uses some model classes to pull back a set of data which it then dynamically displays as a list of checkboxes in a panel control.
When I add one to the page, it works very well indeed.
However, when I add another I get this behaviour:
1. Select an item from the first dropdown, the checkboxes appear underneath ok.
2. Select an item from the second dropdown, the new lot of checkboxes appear ok, but the first lot disappear.
It's rather frustrating, they both have different IDs on the page, so they shouldn't interfere with each other should they? There is some Javascript that I've added but I use the Panel.ClientControlID to separate these out (I've already thought of that one).
I have a masterPage on that i am using AjaxModalPopup for login purpose.My requirement is when i login via Master page then it should show the Logged-in User details on the current Content Page that is using same master page.
Here i am using following code to get it back to the same content page after succesful login but it does not show the user details on the same content page rather when i go to next page then it appears.
if (Session["SignedIn"] == null)
{
ValidateUser();
ModalPopupExtenderMaster1.Hide();
string currentPageUrl = System.IO.Path.GetFileName(Request.Url.AbsolutePath);
Server.Transfer(currentPageUrl);
}
But it does not gives user-details on the same content page.
In my page without using updatepanel page open firsttime it fires only single time, after using updatepanel page load fires twice firsttime page open.. how to solve it.
View 1 RepliesI have a user control (form) inside a user control (grid) with a Validator in the form. A snippet from the code is below
<asp:tablerow>
<asp:tablecell HorizontalAlign="center" columnspan="2" >
<asp:ValidationSummary runat="server" id="ValidationSummary1" />
[code]...
This code is identical to code in another user control where the parent is not a user control and that page works fine, but on this page the Validator doesn't fire and the Foo_ItemCommand method fires instead. I tried searching Google and StackOverFlow but haven't been able to find anything that helps.
I created two instances in a page. The first instance fired up imgMensaje_Click without a problem, but the second one event doesn't fired up at all.

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?
A little confused on something. I have a User Control in a master page. In the User Control there are image buttons. when I try to wire any click event even to say update a label in the User Control itself, nothing gets updated.
It is as if the postback is not handled at all.
What I want to do is click the image button in the User Control and then change a value in the master page. This could happen a few ways but for example it could update a public property or a control itself like a textbox or label.
I have a time on user control, and button on the web page. On perticular time I want to fire button click event.
View 2 RepliesI have a user control with two drop down, on selection change of first dropdown second dropdown should get populated. Now when I place this user control in a aspx file, I need to access the second dropdown value on change of send dropdown .
eg: in ascx file
Department drop down and employee dropdown. on change of department dropdown, employee dropdown should populate. (which is working fine for me)
in aspx.cs file
on change of employee dropdown, I need to get the employee id and so some other operation. (I am struggling here)
Is there any way where I can fire usercontrol event from aspx.cs file?
I've run into a problem with one of my web sites and I am having trouble figuring out the problem and a good solution. This is my scenario: I have a user control that displays a slideshow with images and some text that changes every fifteen seconds. To do this, I have an update panel that contains a timer control with an interval of 15000. It calls a method called slideshowTimer_Tick in the codebehind. The web page that contains this user control is a relatively simple page; no update panels or timers, just divs.
The problem I have is that if I have two of these user controls on the page, the tick event only fires for the first control. It never fires for the second control, although the control is full initialized otherwise.
I am fairly new to the asp.net and experimenting with it to learn the page life cycle. Here is a problem that I have been unable to resolve for past few days.
I have a hosting page (.aspx). Then I have two user controls (.ascx). The page has a place holder control in which it loads the user controls one at a time based on the application flow. First user control is loaded on application start up. It has a "continue" button. Continue button click loads the Second user control that has two buttons - "Back" and "Submit". Obviously the "Back" button should load the first user control again and Submit button should submit the form data. Pretty simple.
The problem is that the command button event handler that I have on the second user control is not firing the first time. (I have one event handler for both buttons). The load event of the user control fires but then it ignores the button click. If I click it again, then it fires. I re-load the controls on the page in every page_load. Here is some relevent code:
AddPlayer.aspx:
[Code]....
The page_Load fires every time but "CommandBtn_Click" doesn't fire after the first click. I have to do it click it again. It doesn't matter which order I click the buttons.
I have a datalist that loops thru cart items. Within the datalist template I call a user control that has a small form that gets repeated for each item. When this control is called outside of the datalist, the form submits fine, but when called within the datalist the button has no event action. I've tried adding an event handler to ItemDataBound of the datalist, but still no event action. How can I get my form to submit?

View 3 RepliesI have a user control that is not visible on the page when the page is first loaded. I have a textbox and on the textchanged event I'm making the control visible, however the control does not reload. Is there a way to refresh the control?
View 1 Repliesi would like to ask about how can i open user control page when i click a button on parent page, also, can i call parent's method from user control page and then refresh parent page?
View 8 RepliesI have a user control that I am explicitely calling from an aspx page. In page_load of hte aspx page I have the following, myControl = (DynamicTable)Page.LoadControl("../inc/DynamicTable.ascx"); Then in my code where I want it to execute the control, I have this pnlESDDEnrolled.Controls.Add(myControl); where pnlESDDEnrolled is the panel I am loading it into for display. So, I execute the aspx page, it links off to the user control, populates the control, returns back to the aspx page and the page dispalys with the user control in the middle of it. All is well.
The problem comes in when updates are made on the user control. Keep in mind, that other data is updated on the page as well, and the update button resides on the page, not the control. Anyway, when the update button is pushed, the button_click event is fired on the page, but the updates that I made on the user control are lost. Since the page loaded the user control and then the usercontrol executed the page unload method, the page has no knowledge of the user control anymore. Thus, when the update button on the page is pushed, I guess I am not really sure what happens with the updated data on the user control. All's I know, it is lost.
Is there a way by which i can achieve functionality of page method inside a user control.

this is my method in aspx.page:
public void MesajlariGetir()

I have an accordian panel that runs fine when the user clicks on the header text. The problem now is I need to have the tab event fire the event that opens the accordian panel.

I have an update panel on the parent page into which I load and remove a set of user controls.
Now, when a button is pressed on the user control, the events are fired but there are no changes in the page. For example:
Main Page
<updatePanelMain>
<childcontrol1>
<childcontrol2>
etc
ChildControl.ascx
<update panel 1>
<panel1/>
<panel2/>
<btn1/>
etc
So, if I want to hide panel 1 when btn1 is clicked etc, I simple use code such as panel1.visible = false.
All this gets executed but nothing happens to the page.
<asp:UpdatePanel ChildrenAsTriggers="false" UpdateMode="Conditional" ID="updatePanel"
runat="server" EnableViewState="true">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
</Triggers>
<ContentTemplate>
However, when I use placeholders instead of update panels in the child controls, I dont face any such problems.
<asp:PlaceHolder ID="placeholderTypeOfInvestor" runat="server">
