 Hi,
    I have to added a custom elements (RadTextBoxElement) to grid cells on the CellFormatting event at runtime.
RadTextBoxElement textbox = new RadTextBoxElement();  
textbox.Alignment = ContentAlignment.MiddleCenter;  
textbox.KeyPress += new KeyPressEventHandler(textbox_KeyPress);  
textbox.TextChanged += new EventHandler(textbox_TextChanged);  
e.CellElement.Children.Add(textbox); 

    I would like to limit the value of textbox not over 99 but i can't set the max length property of the RadTextBoxElement.
Can you help me for solve this problem ?

Hello Duang,

Thank you for writing.

Adding RadTextBoxElement to RadGridView is not a good practice, because the RadGridView behavior may become unpredictable. Is there are a particular reason for going this route?

I would suggest using a standard GridViewTextBoxColumn. You could limit the text length by accessing TextBox in RadTextBoxEditor and set its MaxLenght property. Please, review the code-block below as example:
 
private void radGridView1_CellEditorInitialized(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e) 
    if (this.radGridView1.ActiveEditor is RadTextBoxEditor) 
    { 
        //limit the lenght only for column with index 4 
        if (e.ColumnIndex == 4) 
        { 
            ((this.radGridView1.ActiveEditor as RadHostItem).HostedControl as TextBox).MaxLength = 5; 
        } 
        else 
        { 
            ((this.radGridView1.ActiveEditor as RadHostItem).HostedControl as TextBox).MaxLength = 32767; 
        } 
    } 

I hope this helps.
