Custom Server Controls :: Embedded Javascript File In Custom Server Control?
Oct 19, 2010
I am creating a custom server control, and I am wanting to include a JavaScript file in the dll file when the control is built. I have tried suggestions from the following websites:[URL] But after following the directions, If I use firebug to see what errors show up, the JavaScript functions that are being called all say "goNext is not defined" which leads me to believe the JavaScript file is not being added correctly.
Some information on what my control looks like
I have the JavaScript File in a folder called Script. The namespace of the project is CustomControl, and the Name of the project is MaskedDateTextbox.
I currently have a file "abc.htm" in my Custom Server Control Project and it's Build Action is set to Embedded Resource.Now in the RenderContents(HtmlTextWriter output) method, I need to read that file and render it on the website.I am trying the following but it's to no avail:
protected override void RenderContents(HtmlTextWriter output) { var providersURL = Page.ClientScript.GetWebResourceUrl(typeof (OpenIDSel), "OpenIDSelector.Providers.htm"); var fi = new FileInfo(providersURL); // <- exception here //the remaining code is to possibly render the file }
I'm having a dumb problem that is killing me. I have created the simpelest custom server control in VS 2008 c# called MyMsgBox. On the ASP page I put it in and register it. But, in the .cs file, when I try to call one of its functions I get the compile error that it is not found. The funny thing is that intellesense has it in the list and all of the functions with their given arguements. At the top of the .cs file I am using the namespace. The code for the custom server control is in the App_Code folder. Also when I remove all refrences to its functions, the code compiles and when debugging the constructor for the class MyMsgBox gets hit.
this.msgBox1.confirm("Would You Like to add a new Task for this PO/Contract? ", "hid_f"); Error Message: 'Tasks' does not contain a definition for 'msgBox1' and no extension method 'msgBox1' accepting a first argument of type 'Tasks' could be found (are you missing a using directive or an assembly reference?)

I am creating custom server control. I have two classes in project. One is main class that render control and another will be used to render content based on condition.I just want to know how to render content from other classes in main class.For example. This isjust an example.My main class code
[Code]....
My TopLeftPane class
[Code]....
My page code on page load event
[Code]....
When I run the page, Header title always getting null. This is a just sample code. I will have more than 20 classes so I dont want to write a code in main class to render whole control.I hope all of you understand my problem.
I have to use inline code for an aspx page and I need to use a custom server control that is defined in the same aspx page but the control does not get processed as a server control. it gets returned as is as static html tag.
is it posible to add client side functionality to a custom server control in vb.net?i am looking at msdn library and there is no code for vb :/ http://msdn.microsoft.com/en-us/library/aa719700%28v=VS.71%29.aspxI fount this on MSDN Library Adding Client Capabilities to a Web Server ControlWhat i'm trying to do is to add some client functionality to my control, so that you can get or set some properties/values on client side. From the above link i see that this is doable with Ajax Server Control, but i don't have it, i have Custom Server Control. Can i do this with Custom Server Control and how?
I've build a custom server control inheriting from WebControl. Basically it is a kind of button. All is working perfectly except one thing: the PostBackUrl is inoperative.
I probably forgot to implement something. Actually I just added the property PostBackUrl. Probably I should also implement an interface of call something.
I have a custom server control inheriting from CompositeControl. It consists of two RadioButtonlist controls that are rendered side by side in an html table. The number of ListItems in each RadioButtonList is not known until runtime. Depending on how many items each list contains, the RepeatColumns property of each list is set differently. To do this in the handler for the ItemDataBound event I need to get the count of ListItems in each RadioButtonList. How do I expose the Items.Count property of each internal RadioButtonList as a top-level property? I tried using a getter to return the count but this generates a compile-time error to the effect that the count cannot be assigned to--even though I have not created a setter.
Similarly, in the handler for the Submit event, I need to get the ClientID of each internal RadioButtonList to pass to a method that checks for data changes. How do I expose the ClientID of each component RadioButtonList as a top-level property?
I can of course index the Controls collection of the composite control to access the child control and read its properties--but that defeats the whole point of making a complex, independent custom server control.
I have a control inherited from datalist because I want all the same functionality but with a couple of extra properties.
I have a method that goes off and gets the data inside the control (instead of using a separate datasource ID). It's reading it from XML into a datatable.
If on the code behind of the aspx page I put the control on I put a thecontrol.databind() in the page load, all works well.
However I'd rather not have to do this, instead the control should bind itself.
I gather it's something to do with the order of events but I'm not sure what to do about it.
I don't want to reinvent the datalist wheel, just add a couple of properties and get it's own data
i am making a custom server control. I have embedded images and javascript in class library.But images are not displaying when i use that control in aspx page.my code is
Am building a custom controls that requires a jQuery plugin. It's related JS file is supposed to be registered just before </body> tag. I have this JS file as an embedded resource. So i tried RegisterClientScriptResource method of ClientScriptManager but there is no way of specifying where to register the script. Is there anyway i can achieve it.
I am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:
[Code]....
I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:
[Code]....
I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.
I have created a custom required textbox control. In this control's preinit event i load a css file. Alle css and images are inside the assambly. When i use my custom control on a page the control loads fine and also the css and images are loaded. Validation of the control occures when i click the validate button. So this works perfect. But now i want to use my control in the following senario: I have a grid in an update panel. When i select a record in the datagrid i show a panel in a second updatepanel. Inside this panel i have my custom required textbox control.
The following is happening: I select a record and the panel will be made visible. The custom required textbox control is visible, but the build-in css is not loaded. As a test i have created a new testpage. On this testpage i have put my custom required textboxes in an updatepanel the css is loaded fine. So when my controls are in a panel inside a updatepanel and i set the panel to visible, the css is not loaded.
I'm trying to create a web server control with a css embedded in the assembly.
I marked it as an embedded resource, add assembly attribute to reference it and use the proper methods to include the link to that
css in html code... my page renders ok witk something like <link href='/WebResources.axd?....' />
That's when the problem appears! My control isn't using the css as it appears to not found webResources.axd
I tried directly in web browser to locate http://locahost/mysite/WebResources.axd and it came with http code 404 NOT FOUND
In my IIS i have uncheked "Verify if file exists" on my extensions mapping related to .axd I add HEAD verb in Web.Config to path WebResources.axd and the result is always the same
I have a web control and it needs to inject JavaScript content into ASPX page using RegisterStartupScript. But I don't see a way of doing so. If I use this.Page.ClientScript.GetWebResourceUrl it will return URL which can be used for RegisterClientScriptInclude, but I need the content of the file injected and not reference.
This control may contain some other web server controls such as GridView.I need explanation of experienced developers, how to do that - take me to the right way
