Hi,

I have build a server control (a Column within a Grid) that extends from a third-part library, shown as follows:

   public class RequiredGridBoundColumn : Telerik.WebControls.GridBoundColumn
    {
        private bool _isRequiredField = true;

        public bool IsRequiredField {
            get {return _isRequiredField;}
            set {_isRequiredField = value;}
        }    

This class is placed in a App_Code diretory inteasd of a Assembly. 

I found IntelliSense is invalid after register this class in the .aspx so I must remember properties inherited from base class as well as the one defined in RequiredGridBoundColumn.

What further steps do I need to take to let VS enable IntelliSense of my custom server control?
 

Thanks  a million.

Ricky.

You should create a unique library (dll) for those controls, so you can drag and drop to the toolbox

Hi, this server control is within its parent control, Grid.

It is not be added into toolbox in the thirty party library.

Currently I manually insert the markup as follows:

                <radG:RadGrid ID="RadGrid1" >

                <itcacUI:RadGridBoundColumn DataField="CGROUP_RATIO" DataType="System.Double" HeaderText="??????"SortExpression="CGROUP_RATIO" UniqueName="CGROUP_RATIO" IsRequiredField="True" EnableRangeValidation="True" MinValue="0" MaxValue="100" InputType="Integer">
                </itcacUI:RadGridBoundColumn>

                </radG:RadGrid>

So if I put it into a Assembly, and register this Assembly in the .aspx, the IntelliSense will automatically be enabled?

Thanks,

Ricky.

Yes, that's the easiest way, you can do it using the App_Code as you were doing it, but there are more steps to follow, the easiest way is just wrap your Telerik controls inside your own WebControls dll and you got it made.

Thanks, I'll try!

Ricky.

Let me know how it goes.

Hi, Albert.

I try to implement your suggestion (this is my first time to create a library). But I think of a further question.

Scenario:

My custom control extends Telerik's built-in control so I must reference it, say Telerik.dll, but I do not install Telerik.dll as a Global Assembly. Hence, I would reference it somewhere in my file system.

My custom control is intended to be used in a web site, so the assembly containing it should be put into bin directiory in which Telerik.dll redise as well.

Question:

How I specify my assembly to reference the Telerik.dll in the bin directory of the web site?

Thanks a million.

Ricky.

Ricky,

Sorry for the delay. The telerik controls can be install in the GAC or in the bin directory. When creating a library use reference the assembly and they'll be come dependent, so everytime you reference you library, will copy the dll or reference from the GAC, when publish will copy those.

You should removed them from the GAC so you can handle them better

Hi, Albert.

I'll come back to resolve this issue recently.

Thanks again for your kindly reply. If I make further advance, I'll tell you.

Ricky.

As you said, the intellisense works, if my custom controls are made up as Library rather than just placing within App_Code.

Thanks a million.

BTW: I find that original properties of Telerik controls I extends become invisible on VS designer, how do I make them visible? (Properties appended by me are categorized as Misc)

Regards,

Ricky.
