Is There A Way To Force Specific Order On Extenders Added To The Same Control
Jul 21, 2010
I wrote two control extenders that need to be placed always in the same order. Is there any way to make VS always place them in the correct order?
The only solution i found was to place them in a central repository keyed on the target control ID on their init stage - and then have each of them perform its work through that repository rather then directly. but this looks like an overly complex solution for me.
However, my issue is if the startup.png or any of the apple-touch-icon image files are updated on the webserver, it doesn't seem like a user's iphone or ipod will retreive the updated file once it has been saved to their home screen (I'm guessing it's cached somehow or something). It works to remove the webapp from the home screen and re-add it. But is there a way to let the application know it needs to refresh these images without requiring the user to delete and re-add it?
Two 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 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.
If I have a specific order that I want to sort my List by, how do I do that? For instance, I have a list of items (coming from a database), with ID's ... and they come in order, i.e 1, 2, 3, 4. After receiving this list, I'd like to reorder the list above based on a specific order, e.g. 2, 4, 1, 3. How do I do this without complicate it too much?
I have a FormView with an EditTemplate.And the EditTemplate contains an ascx control:
<asp:FormView ID="fvTicketUpdate" runat="server"
[code]...
The contents of the ascx control has TextBox and DropDownList controls binding to the results of the FormView's ObjectDataSource through Text='<%# Eval("field1") %>'and SelectedValue='<%# Eval("field2") %>'.This works fine and I have been building all of my front end pieces like this as <asp:Panels> rendering as FieldSets that go 100% across the screen.And we call these areas "strips" accross the screen.But now I've run into a problem.One TextBox and one DropDown bind fine to a Ticket Object.But the DropDownList that works has its <asp:ListItems> hardcoded before hand.Now I have DropDownList that gets populated through a WebService in the ascx's code behind like this:
public partial class UserControls_FormControls_PntipUpdtFaaInfo : System.Web.UI.UserControl { protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack)
[code]...
The Problem I think is the FormView is trying to do its Bind to the objectDataSource before its child ascx control is loaded in the Edit Template.And I am getting this error:
Databinding methods such as Eval(),XPath(),and Bind() can only be used in the context of a databound control.Meaning that the control must already be databound to bind the selectedValue to a Property of the TicketObject.Is there an easy way to force the order of loading to make the PntipUpdtFaaInfo control load and have its Page_Load execute and bind ddlEquip before the FormView does its first dataBind and executing its Evals?Otherwise I have to take out the eval on the ddlEquip SelectedValue attribute and go to the Parent Page and hack and force everything to happen when it needs to.This layout has worked out well for me.All of the ascx area strips across the screen share the same Validation Summary for example.It allows me to think about one section at a time and the Properties to the Business Obect and CRUD methods as I go.But this is a big brick wall I've hit.
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 data in mydatabase. My AnswerText in the database is test1,test2,test3 While retrieving it is displaying as test3,test1,test2. I am using the below code to display the data.
Dictionary<string, string> dicKeyValues = new Dictionary<string, string>(); for (int i = 0; i < cnstsData.Answer.Count; i++) { dicKeyValues.Add(AnswerText, AnswerImage); } DataList.DataSource = dicKeyValues; DataList.DataBind();
I want to display the AnswetText as test1,test2,test3. Basically i want the same order which i added to the database while retrieving also.
I have a client request that all times be displayed in Pacific Time Zone, regardless of client settings. I'd like to avoid a scenario where I have to call a function for every time display and instead have a single point where I can make the switch.
I'm thinking a custom culture might do the trick, but I wanted to ask before I set off down a potentially blind alley (or miss something trivially easy).
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?
MSDN documentation says that the ScriptManager class is part of the System.Web.UI namespace and I see that I can create a ScriptManager object programmatically. However, I don't see the ScriptManager control on the front-end. Do I need to reference the Ajax Control Toolkit dll in order to have access to control?
What is the best practice to force the postback Data and ViewState data to be re-loaded on the code behind?
The reason I ask this is, i have one gridview which is generated dynamically and I when it is structure is generated the postback data is already loaded and I want to forse asp.net to reload the postback data once I have my gridView structure is generated.
I have 5 hard corded texboxes in a page in a sequence with sequence Number . Now i want to add re-order /re-arraning functionaly .. but i can't use ajax reorder list because i have 5 hard corded texbox. how can i maintain the order in Insert/Update cases. And also suggest me control that i can use, another than ajax re-order list. coz i not using any list items i have hard corded items on the page.
The AjaxToolkit has a ReorderList. I'm searching for a jQuery solution that does the same and found this page. I would like to change the order of divs (vertically) and upload the new order to the database (ajax).
I know there is another question asking the same thing, but it hasn't gotten any attention for months now:
How to force Ajax Control Toolkit scripts loading from CDN?
I've upgraded my website to .NET4, and I'm now using the scriptManager's EnableCDN="true" tag. My Ajax scripts are being referenced from the Microsoft CDN just how I expected, but I can't seem to get my AjaxControlToolkit scripts to load from the CDN. Instead they all load locally through ScriptResource.axd.
I know where the CDN files are located, and I know that I could reference those files every time I use a control, but I've got a lot of legacy code that loads on its own from the scriptmanager, just pulling ScriptResource.axd files.
how to get the control toolkit scripts to load from the CDN? I already have the standard WebForms.js, etc.
Let me know if there is anything I can clear up, here is the script manager that I'm using: (I have tried the toolkitscriptmanager)
What i need is i need to bind last 10 Order in Gridview/details view with paging, and the same order detail also fetch from database and shown in another gridview.. if user click any oderNo in first Gridview/DetailView then i need to show Respective order detail in anther gridview..
without postback coz we already fetch 10 order with orderdetails from the database..and if user click next 10 orderNo using paging then again we need to load 10 orderNo with respective orderdeatils from database like this going on....as well as let me know how to take print of particular oder and order detail....?
I've created a UserControl that is dynamically placed onto my page during the Init event. It populates and works great, but I'm left scratching my head at how to retrieve data from it during a postback.
It's effectively a multipick combobox that is manipulated entirely using clientside JavaScript (I'm using jQuery heavily). Inside the control container element, I render an empty DIV element that contains all of the selected items. As the user selects items, I generate DIVs within that container DIV that includes some markup. Of interest to me on the server side are the contents of a couple of INPUT fields.
After selecting an item, the rendered HTML looks something like:
[code]....
I may be completely off track and this may actually be impossible (or a stupid idea). The only alternative I can think of is to emit actual ASP.NET controls and hook the built-in event handlers.
From my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
Currently the ListView control displays data horizontally when there are two to three columns. How do I get the ListView control to display data from top to bottom if there are two two to three columns?
