Limiting the text length in RadGridView's cell

HOW-TO

Limit the text length in RadGridView's text column when it is in edit mode
 
SOLUTION

If you need to limit the text length when typing a new value in a text column cell, the best way is to prevent the user from typing more symbols than allowed. This can be done by setting the MaxLength propertyof RadTextBoxEditor's RadTextBoxEditorElement:

VB code:

Private Sub radGridView1_CellEditorInitialized(ByVal sender As Object, ByVal e As GridViewCellEventArgs)

If e.ColumnIndex = 4 Then

If TypeOf e.Column Is GridViewTextBoxColumn Then

CType((CType(Me.radGridView1.ActiveEditor, RadTextBoxEditor)).EditorElement, RadTextBoxEditorElement).MaxLength = 30

End If

End If

End Sub

C# code:

void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)

{

if (e.ColumnIndex == 4)

{

if (e.Column is GridViewTextBoxColumn)

{

((RadTextBoxEditorElement)((RadTextBoxEditor)this.radGridView1.ActiveEditor).EditorElement).MaxLength = 30;

}

}

}
