How To Map A User Control Property To A Server Control Within It
Jun 2, 2010I have a user control with a WebDateTimeEdit server control on it (essentially a TextBox). I'd like to be able to set some of the server control's properties by way of the user control's markup or programatically. for example I have this defined on my user control:
[code]....
this blows up because WebDateTimeEdit1 is null.
is there any way I can make this happen? also can do I do this
myControl2 .Font.Size = FontUnit.Point(8);
where the Font property is read only on the server control?

C# - Invoke A Control To Set A Property?
Mar 23, 2010ASP.net can't update page from event handler
and it's been answered! My only problem is I don't really understand the solution. How does one Invoke the control when setting the property.
I have a label control but there doesn't seem to be an Invoke property/method on it.
I tried this...
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(Label1);
PropertyDescriptor myProperty = properties.Find("Text", false);
myProperty.SetValue(Label1, "my value");
but that seemed to be the same as
label1.text = "my value"
which didn't work

I want to set Value with textbox1.Text, but Value is an Int32. I am looking for something like this:

Can Declaratively Set The Style Property Of A Web Control
Jan 11, 2010I've noticed that on aspx page IntelliSense doesn't display the Style property of a web control, even thought the control does have a Style property. Does that mean we shouldn't declaratively set the Style property:

Web Forms :: Get The Height Property Of Control?
Jan 17, 2011In a Windows App this is considerably easy to get the property value of height or width. However in ASP.Net App it seems rather challenging to get the value. Something like...
Debug.Print(TextBox1.Height) this does not work because cannot be converted to string
Debug.Print(TextBox1.Height.Value) it ends up at 0.0 even though it is really set to 25px
Debug.print(Unit.Pixel(TextBox1.Height).ToString) doesn't work either

View 1 RepliesFont Property For Label Control
Jul 28, 2010I'm trying to learn ASP.NET 3.5 from a book using Visual Web Developer 2008 Express. I've come across a curiosity. The book had me create a Label control and wanted me to change some of the Font properties. I went to the Properties window and saw a heading for Font with a plus sign next to it. I click on the plus sign and the sub-properties for font appear. So far, so good.
When I did the next exercise in the book, it had me create a new Web page with another Label control, and it wanted me to change the Font property again. But, this time when I went to the Properties window, I did not see a Font heading with a plus sign. I simply saw all of the Font sub-properties.

Accessing Property Value Of A Custom Control By Another Custom Control In Design-time
Oct 18, 2010I created an Extender which has a custom property that drills down a list XML elements from an xml file, where users can select xml elements during design-time. This works perfectly fine. However, my code only has a hardcoded xml filename (source of the xml elements list) and I need to change this by maxing the xml file user-specified.
What I did is that I created another control (panel) which has a custom property that when clicked (through the ellipsis), it will allow a developer to select the xml file which is supposed to be the source xml file that the Extenders shall use. The filedialog from custom panel's property works perfectly fine.
However, my problem now is that when I drag-drop my Extender, I cannot find a way to get the property value of the custom Panel Control which contains the xml filename. I tried creating a static variable which I thought the custom controls can share but VS2010 is breaking.
