I have a WebControl that I'm creating and when I'm in the designer...you really can't tell what it is...see Attachment 1 below. See Attachment 2 for what it looks like rendered in the Browser (IE & Firefox). What would cause this. I really can't even throw controls onto the UC looking like this. I have to go into the markup and do the drag and dropping.

I have some webforms in an Asp.Net V2.0 generated using Visual Studio 2005 using Web site technology
Want to import them in to Visual Studio 2008 set to v3.5 (Asp.Net MVC) - where I use Project technology
I'm using Add > Existing Item - Which brings in Whatever.aspx & Whatever.aspx.cs There is no Whatever.aspx.designer.cs to import
How do you force it to be generated ?
How do you delete more than one entity at the same time in the designer Entities list. it seems that the designer interface only allows the selection of 1 entity at a time....
View 1 RepliesI have a combo box that looks great in the designer, the list of choices are perfect. But when I view the ASP code, or the published webpage the choices are seriously garbled. I have tried adding items, but it does not seem to regenerate the code. Any ideas why it happened and what I should do? I do most of my editing through the designer GUI. Note the blank items and even items mixed up together: TVCricket

I have a very unique problem, humm i think. I am using a jquery effect that animate bounce effect, i have a line in my javascript pageLoad function $("#UserBrowserInfoDIV").show('bounce');
- the effects run smoothly but what it does is mess up the bolded text in the div. I have try the items inside the div without bolding and it works fine and no render problem but when bolded the text that are bolded is quite messed up, and barely readable. is there anything else i can do i really would like use this effect.
P.S all the effect have the same render problem, and i am using ie8 under compatibility mode.
I have a page that supports multiple languages (the user can change the language at any time).I update the thread's culture based on the user selection in the Initialize Culture method.
I also update the response object based on the code page for the selected country and set its charset to the WebName of the encoding used (if i don't update the response object based on the code page, then the data bound to controls gets garbled). the resource files are also localized based on the code page.
After doing the above changes, the page is getting displayed correctly in the browser.
However, when the user enters data in one of the Asian languages, the text gets all messed up. The drop down list actually throws the invalid callback or postback argument exception.
On checking the request.contentEncoding i found that it was still UTF-8 (set in web.config).
If I change the request.ContentEncoding during BeginRequest event, the input comes in correctly. But I am not sure of the user selected language this early in the page cycle.
i put this in a grid so that only one of the rows would have the txt box in it, it works ok ie the txtbox only shows up for the row with 1005 as the ID, but for some reason the query string for each row for the last element in the row, ie an AddToCart image button i have at the end of each row in the grid is not coming out right, ie the query string is missing when the page posts back for all but the last row of the grid which coincidently is the row with the 1005 ID, (the rendered code is shown way down, i apologize for the length of it ) here is the problem line. NOTE when i take the code out of the gridview on row data bound event then the page post back fine and the query string is there, but when i put the code back in the row databound event for the grid then the query string vars and values do not get posted back.

Should bar on the HTML designer show the tag name? It sometimes does!
Here's an image of what I referring to.
I thought for sure it must be a bug but considering that I heard that MS was rewriting the editor (designer too?) I am starting to question whether I know how to use it!
Note the "TD" tooltip on the bottom right. Shouldn't this "TD" appear on the bar on the far right where the mouse would be?
I'm using the DataList WebControl for the first time. What I am wanting to do is dynamically load a datalist bound to a datasource with radiobuttons. This datalist control resides within a <div>. In design mode, everything looks great, however, when I run my web app...nothing appears. Do I need to associate the datalist control to the div by chance?
View 10 RepliesI have a ListView control in Asp.Net WebForms which display a set of elements, I have at the end a "More" button like Facebook for example. During the postback I want to get from database another 10 elements (I have already displayed 10 and I don't want to retrieve them again)
Something like this.

1st) Server retrieve an image from Database, in the Database i've only the path, then i encapsulate the image in a XML and i send this XML to the client.
2nd) The client decapsulation the img, so the client has an array of bits with the image. it's not allow send the path for security.
Now i need associate this image with my webcontrol img.
i do something like
ImgUrl = "Handler.ashx?num_doc=13"
and it works, but really i need do something like:
ImgUrl = "Handler.ashx?num_doc=" + num_doc;
where num_doc it's a http parameter recieved from a page. I'll try to put the ImgUrl from code but it doesnt work, just show a path.

I have a page which holds a custom webcontrol and a usercontrol. I need to reference of webcontrol in usercontrol class. So, I make the declaration of webcontrol as public in page class. But, when I do "this.Page.", I don't see the webcontrol listed in list provided by intellisense. Most probably, I am missing something.

I'm using one Sublayout (Sitecore) and have a placeHolder that currently holds 2 webcontrols. I want to access the Label from one Webcontrol to the other Webcontrol.Do i have to find the Label recursively or can i just access the Label on another way? I tried different methods like:
this.Page.Findcontrol
this.Parent.Findcontrol
Label lblSearchTerm = (Label)this.Parent.FindControl("lblSearchTerm");
Label lblResults = (Label)this.Parent.FindControl("lblResults");
any result as being Label lblSearchTerm = null.

I am trying to access a webcontrol (a Textbox) from the EditItemTemplate of a DataList, so I can change it. When I try to do DataList.FindControl("TextboxID") it comes back with null because it doesn't recognize the textbox has rendered. I've tried looking in the DataBinding, DataBound events and those don't work either.
To be more specific, I need to change the value of a textbox when the user uses a Calendar control, so I need to access the control from EditItemTemplate in the Calendar_SelectionChanged event.
Code:
protected void calendar1_SelectionChanged(object sender, EventArgs e)
{
// Access EditItemTemplate Control
}
<asp:DataList ID="DataListMaintenance" runat="server"

I have created a custom web control to act as a button with an image. I would like to be able to set this as the target of the DefaultButton parameter of an ASP.NET Panel control. I have implemented the IButton interface, and no error is generated when loading the page using the control. However, when I press enter in a textbox within that panel, the Click event of the control is not raised. When I replace my control with a standard ASP.NET button, everything works fine.I have a test page with a panel containing a textbox, an instance of my custom button, and a standard asp.net button. The buttons are wired to an event handler which will change the textbox to the ID of the caller.When DefaultButton of the panel is set to the ASP.NET button, hitting enter in the next box works correctly - the page posts back, and the text box is populated with the name of the standard button. When DefaultButton of the panel is set to my button, hitting enter in the textbox causes the page to postback, but the Click event is not fired. Clicking the button manually works correctly.Does anyone know what I have to add to my custom control to make it handle the event coming from the Panel control? I'm looking using Reflector at the source code for Button, but cannot identify what is enabling this behaviour.I have posted the source of the control below, and the relevant source of the test page.Control Source:
public class NewButton : WebControl, IPostBackEventHandler, IButtonControl
{
public NewButton() : base(HtmlTextWriterTag.A) { }
