Two separate questions, but sufficiently intertwined that I'm going to try the two together....
Firstly - User Controls and Behaviours
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
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 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.
I 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...
How can I implement these extenders with the Html.Textbox controls?
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.
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
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.
"EconomicBongah.ascx" UserControl work correctly, because that this usercontrol loaded in Page_Load Event for the first time.
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 have had this exact sample a month ago and it was working perfectly, but for some reason now when I click on the "Next", the page reloads and everything resets, I have an updatepanel in there so it shouldn't be reloading.. Here is my code:
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.
