There are 2 template textboxes inside the grid view. Edit and update button are outside the gridview so that on Click Edit all template textboxes will be visible and while updating labels will be visible.While Edit,cursor is moving from one textbox to another but then disappearing. ( If validation fails in textbox1,then all other rows will become disabled).

How can I make cursor in the template textbox2 upon tab the template textbox1.It is working but disappearing. Appreciate the help

Below is my code . Textbox1 is a template field inside the Gridview and after that I want the cursor on Cells(12).

Dim quantityNEW2 As String = CType(box.NamingContainer, GridViewRow).Cells(12).Text

Actually it coming but disappearing that moment itself. The gridview is in DIV with scroll bar. Even for the First row ,cursor is disappearing after coming to next cell. Appreciate the help



Code as below:

Protected Sub TextBox1_TextChanged(sender As Object, e As EventArgs)
        Dim box As TextBox = CType(sender, TextBox)

        'Dim k1 As System.Web.UI.WebControls.TextBox = CType(box.NamingContainer.FindControl("HiddenField1"), HiddenField)

        Dim hidden As HiddenField = CType(box.NamingContainer.FindControl("HiddenField1"), HiddenField) 'get the hidden which records the index of current row
        Dim quantity As String = CType(box.NamingContainer, GridViewRow).Cells(6).Text 'get the value of quantity
        'NEW

        Dim quantityNEW2 As String = CType(box.NamingContainer, GridViewRow).Cells(12).Text

        Dim count As Int32 = -1
        If box.Text = "" Then   'box is reciept
            box.Text = 0
        End If
        If CInt(box.Text) > CInt(quantity) Then

            For Each item As GridViewRow In kgrid.Rows   ' if not, make the following row invisible
                If item.RowType = DataControlRowType.DataRow Then
                    count = count + 1
                    If count > CInt(hidden.Value) Or count < CInt(hidden.Value) Then
                        item.Enabled = False
                        Update.Visible = False
                        MESSAGELBL.Text = "Quantity must be Less than ABC"
                    End If
                    If count = CInt(hidden.Value) Then
                        Update.Visible = False
                        MESSAGELBL.Text = "Quantity must be Less than ABC"
                    End If
                End If
            Next
        Else

        End If

        If CInt(box.Text) <= CInt(quantity) Then    ' if so ,make the following row visible

            For Each item As GridViewRow In kgrid.Rows
                If item.RowType = DataControlRowType.DataRow Then
                    count = count + 1
                    If count > CInt(hidden.Value) Or count < CInt(hidden.Value) Then
                        item.Enabled = True
                        Update.Visible = True
                        MESSAGELBL.Text = ""
                    End If
                    If count = CInt(hidden.Value) Then
                        Update.Visible = True
                        MESSAGELBL.Text = ""
                    End If
                End If
            Next

        End If

Hi shsu,

You haven't set the textbox focus in your TextBox1_TextChanged.

Below is my test code.

Public Partial Class MoveCursor
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        If Not IsPostBack Then
            GridView1.DataSource = New Integer() {1, 2, 3, 4, 5}
            GridView1.DataBind()
        End If
    End Sub

    Protected Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As EventArgs)
        Dim row As GridViewRow = TryCast(((TryCast(sender, TextBox)).NamingContainer), GridViewRow)
        Dim field As TextBox = (TryCast(row.FindControl("TextBox2"), TextBox)) ' find the textbox to be focused

        For Each item As GridViewRow In GridView1.Rows

            If item.RowIndex <> row.RowIndex Then
                item.Enabled = True
                item.Visible = False
            End If
        Next

        field.Focus()
    End Sub
End Class

<form id="form1" runat="server">
        <div style="width:100px;overflow:scroll">
        <asp:GridView ID="GridView1" runat="server">

            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox1" runat="server" OnTextChanged="TextBox1_TextChanged" AutoPostBack="true"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox2" runat="server" ></asp:TextBox>
                      
                 
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
            </div>

    </form>

The result.

If it is not your case , please post your aspx code.

Best regards,

Ackerly Xu
