[Nipuna]

'Could anybody plesae tell me , how can I add a new row to this table using VB code ?

  

'dgPeripherals.AllowAddNewRow = True

'dgPeripherals.Rows.Insert(0, dgPeripherals.Rows.NewRow())

'dgPeripherals.Refresh()

 

'But it does  display me a new row insert recrods to the grid.

'I have added above code inside the hander event of the Add button as follows ,

 

 

Imports Telerik.WinControls.UI

Imports Telerik.WinControls.UI.GridViewColumn

 

Private Sub FormTeleic_Load(sender As Object, e As EventArgs)

        Me.dgPeripherals = New Telerik.WinControls.UI.RadGridView()

        GeneratePeripheralsGridColumns()

End Sub

 

 Private Sub dgPeripherals_CommandCellClick(sender As Object, e As EventArgs)

         

            Dim gCommand As GridCommandCellElement = TryCast(sender, GridCommandCellElement)

            Dim result As DialogResult

            If gCommand.ColumnInfo.Name = "clmAdd" Then

                dgPeripherals.AllowAddNewRow = True

                dgPeripherals.Rows.Insert(0, dgPeripherals.Rows.NewRow())

                dgPeripherals.Refresh()

            End If

End Sub

 

 

 

Private Sub GeneratePeripheralsGridColumns()

 

        ' TEXT COLUMN

        Dim clmItemSN As New GridViewTextBoxColumn()

        clmItemSN.HeaderText = "Item S/N"

        clmItemSN.Width = 100

 

        Dim clmItemName As New GridViewTextBoxColumn()

        clmItemName.HeaderText = "Item Name"

        clmItemName.Width = 100

      

        Dim clmAdd As New GridViewCommandColumn()

        clmAdd.Name = "clmAdd"

        clmAdd.UseDefaultText = True

        clmAdd.DefaultText = "Add"

        clmAdd.HeaderText = "Add"

 

        dgPeripherals.Columns.Add(clmItemSN)

        dgPeripherals.Columns.Add(clmItemName)   

        dgPeripherals.Columns.Add(clmAdd)

  

End Sub

 

' What I want is to add a new row to the excisting grid when clicked on the Add Button on the previous row

'The default behaviour is , it adds  a new row to the grid when I press enter on the last text cell , but I want this to happend upon add button click event.

'Is this possible to achive with Teleric Grids ? Can somebody help me please ?

'I'm new to teleric grid , please bear with me if I missed anything,

'Thanks in advance.

Hello Nipuna,

Thank you for writing.

From you code snippet I understand that you are having a RadGridView with a GridViewCommandColumn and you would like to add a new row in your grid on a click event in the command cell. Please check my code snippet below: 

Partial Public Class Form1

    Public Sub New()
        InitializeComponent()

        Me.BindGrid()
        Me.RadGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill
        AddHandler Me.RadGridView1.CommandCellClick, AddressOf RadGridView1_CommandCellClick
    End Sub

    Private Sub BindGrid()
        Dim decimalColumn As New GridViewDecimalColumn()
        decimalColumn.Name = "DecimalColumn"
        Me.RadGridView1.MasterTemplate.Columns.Add(decimalColumn)

        Dim textBoxColumn As New GridViewTextBoxColumn()
        textBoxColumn.Name = "TextBoxColumn"
        Me.RadGridView1.MasterTemplate.Columns.Add(textBoxColumn)

        Dim commandColumn As New GridViewCommandColumn()
        commandColumn.Name = "CommandColumn"
        Me.RadGridView1.MasterTemplate.Columns.Add(commandColumn)

        For i As Integer = 0 To 19
            Me.RadGridView1.Rows.Add(i, "Name " & i, "Add Row")
        Next
    End Sub

    Private Sub RadGridView1_CommandCellClick(sender As Object, e As EventArgs)
        'Me.RadGridView1.Rows.Add(20, "New Name", "Add Row")
        'Me.RadGridView1.Rows.AddNew()
        Me.RadGridView1.Rows.Insert(0, Me.RadGridView1.Rows.NewRow())
    End Sub

End Class

Additional information on how rows can be manipulated you can find in this section of our documentation: RadGridView | Rows.

I hope this help. Should you have further questions please do not hesitate to write back.
