I have a UserControl that is Added dynamicatlly into the page using UpdatePanel. That user control has an extender that does not work.
View 4 RepliesTwo separate questions, but sufficiently intertwined that I'm going to try the two together....
Firstly - User Controls and Behaviours
I have a User Control which contains a few visual controls. I am attaching some behaviours by using GetScriptDescriptors and am passing some JavaScript to the browser using GetScriptReferences. That is all rock solid and working well. However, when developing, I did discover that I couldn't attach the ehaviours to the User Control itself - not surprising as rendering a User Control does not create a DOM element which represents the actual control. So, I have attached my behaviours to a "random" TextBox within the User Control.
So - first question, is there a better way to do that? For example, should I always be rendering a SPAN as an element to surround the control? Not sure what that would do to the robustness of the rendering. What is the right way to attach a behaviour to a User Control.
Secondly - Accessing those same Behaviours later
Assume I have placed a User Control on the page. That User Control exposes a Property (actually a Javascript Function of course) which does "something" to the control - for the sake of example we'll say that the function is set_Border(colour). I then have a behaviour on the same page (actually an Extender on a different control) which needs to call the function. I have a reference to the User Control in my script, so I have tried TheControlReference.set_Border('red') and find that my control doesn't support the set_Border method.
I guess this is probably because the behaviours are not attached to the User Control itself, but to a GUI element within it. Hence, I suspect that the answer to the second question lies within the answer to the first.
I often use Placeholder control to dynamic load the UserControl. However there is a problem when i use, AJAX Control Toolkit not work on UserControl.
I would like for example a specific example as follows:
- This Project has 2 folder as "not use placeholder" and "Use placeholder". In folders have 2 file, default.aspx and uc1.ascx have the same content.
- In the folder "not use placeholder", I add CalendarExtender in uc1.ascx and run normally and in the folder "use placeholder" then CalendarExtender is not working.
I have a FileUpload Control on the page with validation and it is working smoothly.
Later there is an important demand to have it partially updated so we enclose it with UpdatePanel.
Then problem comes up when user browse file and press upload button, no file is uploaded.
Is it we cannot do partial rendering with FileUploader ?
I download Ajax control toolkit to use it in my website. I readed "Using AJAX Control Toolkit Controls and Control Extenders (C#)" to known how i can use them. In the Control extenders when i added a button to My Webpage, How can i find "Add Extender task option" ? because i should click on it to set the options.The Add Extender task option is not appear...! I was reading the page [URL] that i encountered this problem.
View 4 RepliesI am quite new to asp.net. I would like to ask for some advice on how this scenario can be achieved. Here is the problem:
I have a 5 gridviews on my page. In each gridview, I have two important columns. They are SellerID and BuyerID. Because I already have too many gridviews on the page, I want to load a webuser control with a modalPopupExtender when either SellerID or BuyerID is clicked. That is to say if a user select a SellerID, the details information about that SellerID should be loaded with DetailView from the user control and if the buyerID is click, the details information about that buyer should be loaded with another detailview
from the user control as well.
My problem is I do not know how to get the Selected Value from the gridView since the DetailView is in the WebUserControl. One more thing, both SellerID and BuyerID are in the same GridView, so how can we distinguish when a user select a SellerID or vice versa.

I am try to migrate an asp.net web application to mvc. The problem im having is that it uses all asp controls and a ton of ajax control extenders like filtered textbox, masked textboxes, confirm extender, modal popup, the calander, ect...

I have a custom control created to autofill the box as typed in. Its working great. But if I put the control inside an Update Panel, it works for the full postback but if partial postback happens (because of the update panel), it does not work.
View 7 RepliesI'm new in developing and i'm in trouble with update a UpdatePanel inside a User Control from a Repeater inside another User Control.
View 3 RepliesI have an ASP.NET page with the following controls on it.
<asp:UpdatePanel ID="UpdatePanel3" UpdateMode="Conditional" runat="server">
Wasn't quite sure where to post this, seems like the issues could be any number of things, so I'm trying to keep it general... mods, feel free to relocate appropriately.
I am trying to build a page which will load various web user controls dynamically in response to menu selections made by the user, and then allow other interactions inside those controls (such as gridview manipulation and updates). The content page simply has a loginview, an ASP:Menu control, and an ASP:Placeholder. The placeholder is filled by the appropriate user control in response to the menu selection. Selecting a menu item causes a postback and the correct control is loaded as expected.
I realized that using dynamic loading with interactive controls would be a problem with respect to postbacks, so I added a ScriptManager to the content page and enclosed the gridview controls in the web user controls within UpdatePanels, thinking that all postbacks required by the GridView would be handled inside the UpdatePanel and not cause the parent page to refresh (which would then wipe out the dynamically loaded control). However, it does not seem to work this way. Instead, although the control containing the GridView loads correctly and displays data, when I attempt to page, edit, or select any item on the GridView, nothing happens on the first click. If I click on any item inside the control a second time, the entire page refreshes and the control and its contents disappear.
I have removed all the code inside the web user control and placed it directly into the content page to test, and everything functions correctly in that case. I think therefore that I must be missing something with how the user control is working, particularly with respect to the UpdatePanel. Is it just not possible to use an UpdatePanel to confine actions inside a user control that would otherwise cause the entire page to postback, or am I missing something somewhere?

ScriptManager exist in MasterPage. I registered trigger by timer.I want to update color of rectangle in Map.aspx. but It is not update. If use Label instead of Image Control, update is done. - structureDefault.aspx have table. table have cell. cell have usercontrol. usercontrol have updatepanel.updatepanel have image control. image control have Draw.aspx in ImageUrl.- Code Sample1. MasterPage behind Code
protected void Page_Load(object sender, EventArgs e) { ToolkitScriptManager1.RegisterAsyncPostBackControl(Timer1); }
protected void Page_Load(object sender, EventArgs e)

I have a user control 'UserControl1'.
Which is in update panel of ajax.
Now i want to use trigger in update panel.
Then what should i write in eventname of trigger
<Triggers>
<asp:AsyncPostBackTrigger controlid=" UserControl1 " eventname="????" />
</Triggers>
I thought the whole idea of allowing user to create their own custom controls was to built pages in small parts, share the control with other etc. But that doesn seem like the case. I was trying to organize a very heavy page into user controls and thats when i faced this problem.
here is the architecture that i have
Main Page: AjaxExtension Script Manager
Usercontrol1 (uc1): Script Manager Proxy, Reference to Ajax Toolkit Assembly, Autocomplete Extender, Webservice Method in uc1.cs
Usercontrol2 (uc2): Script Manager Proxy, Reference to Ajax Toolkit Assembly, Autocomplete Extender, Webservice Method in uc2.cs
It doesnt work. But when i placed that webservice method in the MainPage.cs it starts working. If this is how its suppose to work then that means to me that user control only supports full designing features however programing screws are missing in it.
In my web page, i have user control inside update panel, user control refreshed every time update by update panel.
View 3 Repliesmy problem is it that i when loaded usercontrol in Updatepanel dynamically,so can not execute javascript or jquery code in second usercontrol.
"EconomicBongah.ascx" UserControl work correctly, because that this usercontrol loaded in Page_Load Event for the first time.
when i click on the btn_Article,"EconomicArticleMarket.ascx" UserControl Get loaded, but with the first user control code will interfere,and therefor Javascript or jquery code in second usercontrol can not execute, and encounter with error in Jquery-1.4.4.js file.
i loaded usercontrol dynamically in this case:

Using ASP.NET 3.5 / C#. Have a page with a UpdatePanel, and a UserControl inside the UpdatePanel. When calling ScriptManager.RegisterClientScriptBlock(this, typeof(UpdatePanel), Guid.NewGuid().ToString(), script, false); the script appears to fire (have tried it with a JS alert), but the resulting script also disappears immediately afterword. I am trying to create a JS function via the script, and it is not in the Page Source after the Page is rendered. i have tried many variationsRegisterClientScriptBlock with no luck.

I have calendar extender in asp panel which is in updatepanel. These asp panels are switched through two radio buttons.First time calendar displays well, but if we switch to other panel and come back to same, the format changes.I have analysed that CalendarExtender renders class="bgcolor_weekend" properly on page load first time, but when some action is done (check box switched to show one panel and hide another) while being in updatepanel, it simply does not enderlass="bgcolor_weekend" on weekend column.

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.

when put the calendar extender in bodt tag with dir="rtl", the web page not work currectly and hang web page and lock page.
