Hi,

If I bind to a datatable, how can I get the ID of the selected item in the combo box. I have added the following code

Dim pobjTable As New Data.DataTable

pobjTable.Columns.Add("ID")

pobjTable.Columns.Add("Name")

pobjTable.Rows.Add(1001, "User A")

pobjTable.Rows.Add(1002, "User C")

pobjTable.Rows.Add(1003, "User B")

RadComboBox1.DataSource = pobjTable

RadComboBox1.DisplayMember = "Name"

So if User C is selected, I would like to get 1002 back as the ID.

Note: This is possible in the VB.Net Combo Box if you create a class to store the ID and the Text Value. You can add an object to the List and return the Object once selected.

Best Regards
Eddie

Q2 2007 SP1 GridView Cell Max Text Length

The GridView throws a general GDI+ exception when a string of length 2^16 or greater is bound to the row.

Here is an example:

using System.Text; 
using System.Windows.Forms; 
 
namespace TelerikGrid 
{ 
    public partial class Form1 : Form 
    { 
        public Form1() 
        { 
            InitializeComponent(); 
 
            StringBuilder text = new StringBuilder(65536); 
            for (int i = 0; i < 65536; ++i) text.Append('B'); 
 
            GridText gridText = new GridText(); 
            gridText.Text = text.ToString(); 
 
            radGridView1.DataSource = new GridText[] {gridText}; 
        } 
    } 
 
    public class GridText 
    { 
        private string _text = string.Empty; 
 
 
        public string Text 
        { 
            get { return _text; } 
            set { _text = value; } 
        } 
    } 
}

Creating RadShapedForm?

I downloaded the RadControls for WinForms and I'm having a little trouble. I was trying to use a RadTitleBar control, and looking at the documentation it says to start by creating a RadShapedForm.

The documentation says to create the RadShapedform as mentioned in the QuickStart.

My problem is, I can't seem to find a QuickStart that describes how to create a RadShapedForm.. I tried searching the documentation and it turned up nothing.

Thanks!!

Inheriting from a rad control and themes

Hello,
I've been trying to create a custom RadTreeView with a different default theme, but apparently no can do. It seems that the theme I assign to my custom RadTreeView is lost when I add my custom RadTreeView to a new form. Am I doing something wrong here?

Exception when binding

I am having such a hard time adding elements to the grid... I have made the grid bind to a custom BindList, but when adding elements to my list I get a exception. Do you have a example binding to BindList, or better yet I just need an unbound example...

         mGridData = new BindingList<SentenceViewerGridData>();  

         mRadGridView.DataSource = mGridData;  

         foreach (Element sentence in elementArray)  

            {  

               mGridData.Add(new SentenceViewerGridData(sentence.Field[0], sentence.Field[1]));                 

            }

Value of '101' is not valid for 'Value'. 'Value' must be between 'Minimum' and 'Maximum'.
Parameter name: Value
