Validating input of datagrid?

Hello,


Is there a way to validate the user's entries to the Datagrid, for example Letters only or Digits onle..etc...


Thanks,
Sushu

any help...? :sick:

Can you please help me with it...?

In ASP.NET or VB.NET?

VB .NET

This is what I have

VB Code:

Dim dgts As New DataGridTableStyle
        dgts.MappingName = DirectCast(dtgTechInfo.DataSource, DataView).Table.TableName
 
        Dim dgtbc1 As New DataGridTextBoxColumn
        dgtbc1.MappingName = "ITtechname"
        dgtbc1.HeaderText = "Technician name"
        dgtbc1.Width = 100
        dgts.GridColumnStyles.Add(dgtbc1)
 
 
        Dim dgtbc2 As New DataGridTextBoxColumn
        dgtbc2.MappingName = "Phone"
        dgtbc2.HeaderText = "Phonenumber"
        dgtbc2.Width = 100
        dgts.GridColumnStyles.Add(dgtbc2)
 
        Dim dgtbc3 As New DataGridTextBoxColumn
        dgtbc3.MappingName = "Email"
        dgtbc3.HeaderText = "Email address"
        dgtbc3.Width = 100
        dgts.GridColumnStyles.Add(dgtbc3)
 
        dtgTechInfo.TableStyles.Add(dgts)

I want to validate..so the user can enter letters only for name, digits only for number....

thanx

Any one knows...?

Hola , i had this question and its resolves with:

For numbers only :

VB Code:

Public Class DataGridDigitsTextBoxColumn
    Inherits DataGridTextBoxColumn
 
    Public Sub New()
        AddHandler Me.TextBox.KeyPress, New System.Windows.Forms.KeyPressEventHandler(AddressOf HandleKeyPress)
 
    End Sub
 
    Private Sub HandleKeyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs)
 
        If (Not (System.Char.IsDigit(e.KeyChar)) AndAlso Not (System.Char.IsControl(e.KeyChar)) AndAlso e.KeyChar <> ".") Then
            e.Handled = True
        End If
 
    End Sub
End Class

For letters only :

VB Code:

Public Class DataGridLettersTextBoxColumn
    Inherits DataGridTextBoxColumn
 
    Public Sub New()
        AddHandler Me.TextBox.KeyPress, New System.Windows.Forms.KeyPressEventHandler(AddressOf HandleKeyPress)
 
    End Sub
 
    Private Sub HandleKeyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs)
 
        If Not (System.Char.IsLetter(e.KeyChar) Then
            e.Handled = True
        End If
 
    End Sub
End Class

I hope that this helps you. :wave:
