I have a custom control. Some properties throw a custom error message when no value is supplied. The message shows up fine, but also does the code. For example ...
Custom Message Here
... and then in the yellow box the code ...
throw new Exception("Custom Message Here");
How can I hide the code portion?
I am creating a custom control by inheriting a server control, say LinkButton. There are properties like "BorderColor" available in LinkButton. Let's say, I don't want this particular property to be available when I create an instance of the custom control.
I want to completely hide this particular property (I don't want to override it but disable it.)
My code is as follows:

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.

i have this application structure:
1. Presentation Layer which calls
2. Business Logic Layer which in turn calls
3. Data Access Layer to do the dealing with the database.
Now i have a Contacts page from where i can add a new contact to the database.So to add a New Contact i fill in all the required details and then call a Add Method (residing in the BLL) from the page, which in turn call a Add Method residing in the DAL.this method in the DAL returns the Current Identity of the record which is then return back to the BLL method and finally delivered on the page.this is fine. but what if a get an exception how do i handle it properly because the method in DAL has a return type of int and i dont want to throw another error!! coz other wise i will have to write try catch in almost all the methods.
//something like this
public int AddMethod(ContactClass contactObj)
{
int result = 0;[code]...
rather i want to show the user a user-friendly message which they can easily understand and in the mean while i will send a mail to myself documenting the Error that just occurred.how can i implement my custom exception classes.
I have created a custom control that implements Templates (based on Panel controls) ... I can do a FindControl to locate imbedded controls. This allows me to get and set values in the imbedded controls, but I want to be able to reference the imbedded controls like they are properties of the associated panel. Here is a sample of how my custom control now works:
<cc:CustomControl ID="myCustomControl" runat="server">
<PanelTemplate>
<asp:TextBox ID="myTextBox" runat="server"></asp:TextBox>
</PanelTemplate>
</cc:CustomControl>
I can do the following (where my custom control has given the panel hosting the template the name "myPanel"):
Dim txt As TextBox = myCustomControl.myPanel.FindControl("myTextBox")
txt.Text = "Some text to put in TextBox"
What I want to do is:
myCustomControl.myPanel.myTextBox.Text = "Some text to put in TextBox"
when I add a custom usercontrol by code like this:
[Code]....
the compiler doesn't accept it at all...
how to access "custom usercontrol's properties" while the usercontrol itsef has been added programaticly by code.

In ASP .NET 2.0, I've created a user control which is meant to work as a dropdown or popup by using an <input type="button" id="btnTogglePopup" runat="server" style="display:inline"... /> and <div id="divPopup" runat="server" style="display:none" ... /> the rest of the controls are contained inside this div, and they do mantain their values between posts, etc. This button 'runs at server' but it's not intended to post back or submit.It just toggles the popup (div) visible/hidden using Javascript client code by setting the div's style display property to "none" or "block" The problem I'm having is that when a page containing this control posts back, the state visible/hidden of the div is not maintained. If the user had the popup open, after the postback, it will display closed.I've read a bunch by now about ViewState & ControlState, and have the save and load contol state methods working, but when I step thru them they load old values (setting the popup to hidden all the time),and the popup doesn't work! I've come to think that b/c when the button is clicked,the visible state of the div is changed in client code w/o a postback, maybe I have to maintain this state info in a hidden fiel or something like that?At the same time I don't want to have a hidden field if it's unnecessary,and I may just doing something wrong.

I've created a web user control for my site's footer. In my web.config I have it registered like this:
[Code]....
Then, within the pages on my site, I simply insert it like this:
[Code]....
But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)
So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.
I'm encountering the following exception everytime i try and install any of the following.

Also, when I'm trying to udpdate SQL Server 2008 R2 products using SQL Server Installation Center, it's throwing the following error.

Is there any compatibility issues with the SQL Server 2008 with 64bit Windows 7 OS ?
I have developed a User Control in inline code model and convert this into dll and try to add it into Visual Studio ToolBox. It shows error "There is no component found in the object.". It is showing actually because i have not added ToolBoxData attribute just before the class declaration, because there is no class declaration in the inline code model. I don't know where i have to add ToolBoxData attribute.
View 1 RepliesI 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.

when a user enters a bad email I am doing a check on this and throwing an exception message as follows, this works fine on the test site but for some reason the same code on the live site gives a "internal server error" (http code 500). The code below:
[Code]....
not certain why this is happening, I assume that it's some server or config difference between the test and live sites. has anyone seen this before? For a quick fix i'm registering javascript alert and showing the same text so it works but I would like to figure out why the code above is not working.
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 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.

View 16 RepliesI'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.
