Hi sking,
saying object not set to an instance. I don't get this and I tried this as a template field as well as a boundata field. I'm trying to check the checkbox to see if it is checked or not checked.
If it's checked it is replaced with an X and if not then the cell is set to a space.
What is the value in the propertysubject field? Boolean value?
I created a simple example based on the existing code, but failed to reproduce your problem.
<body>
<form id="form1" runat="server">
<div>
<asp:GridView runat="server" ID="GV1" AutoGenerateColumns="false">
<Columns>
<asp:BoundField DataField="propertytiho" HeaderText="propertytiho" SortExpression="propertyitho" ItemStyle-Width="125px" />
<asp:BoundField DataField="propertyrentalinc" HeaderText="propertyrentalinc" SortExpression="propertyrentalinc" ItemStyle-Width="125px" />
<asp:TemplateField ItemStyle-Width="125px" HeaderText="">
<ItemTemplate>
<asp:Label ID="lblnetrent" runat="server" Text=""></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="propertysubject" SortExpression="propertysubject">
<ItemTemplate>
<asp:CheckBox ID="propertysubject" runat="server" Checked='<%# Bind("propertysubject") %>' Enabled="false" />
</ItemTemplate>
<ItemStyle Width="125px" />
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
</form>
</body>
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Dim dt As DataTable = New DataTable()
dt.Columns.Add("propertytiho")
dt.Columns.Add("propertyrentalinc")
dt.Columns.Add("propertysubject")
dt.Rows.Add("propertytiho1", "propertyrentalinc1", True)
dt.Rows.Add("propertytiho2", "propertyrentalinc2", False)
dt.Rows.Add("propertytiho3", "propertyrentalinc3", True)
dt.Rows.Add("propertytiho4", "propertyrentalinc4", False)
GV1.DataSource = dt
GV1.DataBind()
End If
End Sub
Protected Sub GridView2_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GV1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
'Dim value As String = e.Row.Cells(3).Text
'If e.Row.Cells(3).Text <> "" Then
' e.Row.Cells(3).Text = String.Format("{0:###,###}", Convert.ToDecimal(e.Row.Cells(3).Text))
'End If
'Dim status As String = e.Row.Cells(4).Text
'If status = "1" Then
' e.Row.Cells(4).Text = "Sold"
'ElseIf status = "2" Then
' e.Row.Cells(4).Text = "Pending Sale"
'Else
' e.Row.Cells(4).Text = "Retained"
'End If
'If e.Row.Cells(5).Text <> "" Then
' e.Row.Cells(5).Text = String.Format("{0:###,###.00}", Convert.ToDecimal(e.Row.Cells(5).Text))
'End If
'If e.Row.Cells(6).Text <> "" Then
' e.Row.Cells(6).Text = String.Format("{0:###,###.00}", Convert.ToDecimal(e.Row.Cells(6).Text))
'End If
Dim cb As CheckBox = CType(e.Row.FindControl("propertysubject"), CheckBox)
If cb.Checked = True Then
e.Row.Cells(2).Text = "X"
End If
'Dim delete As ImageButton = CType(e.Row.FindControl("deletebtnre"), ImageButton)
'delete.OnClientClick = "return confirm('Are you sure you want to delete this item from " & e.Row.Cells(2).Text & "?')"
End If
End Sub
This test can normally change the text content of lblnetrent according to the status of the checkBox.
If possible, could you provide more details?
