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.

When i rendered more than one control in the aspx page, the css will loaded the number of times the controls in the page. I want to load the css file only one time. How to check the webresource css file on rendering whether it is loaded or not.
View 1 RepliesI 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.
In my AssemblyInfo I have the following:
<Assembly: AssemblyVersion("1.0.*")>
I hope this is the right place to ask this question. I'm trying to make a control class library. I want to have a GenericHandler as a WebResource so I could call it from the web project that will use that control.
I need this handler will get parameters from the query string and return JSON data acourding to what it get in the QS.
I know how to create JS and images WebResources, so I tried the same on a generic handler I added to the class library project but all it does is return the source of the handler file and not the result.
I try to mak a custom textbox. Something pretty easy to do but I can't figure out one thing. When I write my textbox in designmode I have this <custom:Textbox runat="server" ID="Textbox1">Test</custom:Textbox> The problem is The textbox is a webcontrol I added to my class [Parsechildren(false)] like this [Parsechildren(false)]
public class Textbox : WebControl
{
}
now the problem is I want to able to write the Text from the textbox between the beginningtag and andingtag but I want to disable every other control in designmode. When I add < between the tags then you can see you can write all tags between it. disable all controls except literal between the tage in designmode?
i registered an image in AssemblyInfo.cs like this:

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.
<%@ Register TagPrefix="cc1" Namespace="CustomServerControls" %>
...
<cc1:MyMsgBox ID="msgBox1" runat="server" />
Task.aspx.cs
...
Using CustomServerControls;
...
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'm creating an ASP.NET Control which has a property collection for Columns which the user can edit in the Property Collection Editor..
In most circumstances this works fine, the collection can be edited in the designer and the appropriate tags are added inside the control in the ASPX file.
It works fine when
My control is added to the form
[Code]....
My control is added inside an Update Panel
[Code]....
[Code]....
However, if My control is inside a Content Placeholder which is inside an Update Panel, it fails to work as it should. In this scenario, when the Columns collection is edited in the designer, if you then switch back to Source view, the Columns collection is emptied. I have to save the aspx page before switching back to Source view for the changes to be kept.
[Code]....
how to get around this problem? Is there something I may have missed?
Here's the code for the Control

I want to write own control which can contain other. And I want to define content of the control in the .aspx file where the control is defined. I have written such control. But now I have issue with ViewState of inner controls of my control. The following samle illustrates the issue: I defined two asp:DropDownList ID="ddl1" and ID="ddl2" One of them is inside of my control and other is outside. When posback is occurred asp:DropDownList ID="ddl1 loses state and becomes empty. How to say ASP.net to store state of inner controls defined by this way?

View 2 RepliesThere is a lot of discussion about todays fix for ASP.NET to prevent an attack that can be used to get the encryption keys from an application. In one discussion I read that it could also be used to make the WebResource.axd handler return any file in the application by forging the request parameters to point to a known file location (where /web.config would be the most obvious choice).

View 6 RepliesI wish to execute a javascript function in HTML Editor content. Hower, I give me the error "object expected". It seems like the browser cannot locate my javascript file.
Here is my setup:
- I have an external javascript file, "myscript.js" under "script" folder which has "test" function which contains a single "alert()" command.
- I referenced to "myscript.js" via <script src=....> tag (and also tried using Script manager's ScriptReference Path, same result).
- In my default.aspx page, I have a button which call "test" on mouseover event, which works call "test" correctly whenever I mouseover.
- In my default.aspx, I have the HTML Editor, with the this HTML content:
<span id="0001" onmouseover="alert('ok');">OK</span>
<span id="0002" onmouseover="test('not ok');">Not OK</span>
When I mouseover "ok" alert() script executed, but it give "object expected" error on I mouse over "not ok", it look like the browser cannot find "test" in myscript.js.
How do I reference this a script file inside the HTML Editor content?

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 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.
