Help with Customized TextBox control.

[Sanjay Pais]

Hi,

I have successfully added my TextBox control that inherits from the
TextBox. I have added a property called ApplySecurity that can be changed in
the designer and is reflected in the source HTML.

I want to add the TextBox icon in the toolbox and want the value to toggle
in the property window in design mode. The values allowed are True & False.
How can I achieve this?

We are using VS 2005 Beta 2

Cheers

Sanjay

using System.Collections.Generic;

using System.Text;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.ComponentModel;

using System.Drawing;

using System.Diagnostics;

using System.Design;



[ToolboxData("<{0}:ATextBox runat=server
ApplySecurity=False></{0}:ATextBox>")]

public class ATextBox : System.Web.UI.WebControls.TextBox

{

[Bindable(true),

Description("A custom AE Textbox"),

Category("Misc"),

DefaultValue("False")]

private string strApplySecurity = "False";

public string ApplySecurity

{


get

{

return strApplySecurity;

}

set

{

strApplySecurity = value;

}



}

protected override void Render(HtmlTextWriter w)

{

w.AddAttribute("ApplySecurity", strApplySecurity);

base.Render(w); }

}

Hi,

What if the type of the ApplySecurity property would be bool and you'd
handle the translation to string in the AddAttribute method? bool type would
automatically get True | False selection to property browser (if that's what
you mean).

What comes to the icon, check ToolboxBitmapAttribute

Thanks for the reply. I actually did finally implement the TrueFalse value
as a bool flag and was able to get the toggle in the properties window.

I want to use the icons from the system equivalent so for example, if i am
creating a custom control that inherits from the TextBox, how can I use the
icon for the textbox in my toolbox?

Thanks in advance
