Hello,

Is it possible to display a message in a GridView such as "No Records
Available" when the DataSet is empty?

Thanks,

Miguel

Hi Miguel,
GridView contains EmptyDataTemplate which is used in your case.

or you could just not show the grid and show a message in its place if your 
ds is empty.

something like
if(ds.row.count > 0)
{
      show grid
}
else
{
          show no records found message
}

You can also, if you would prefer the columns and grids did not
display as there is no data, to read the property Rows from the
GridView, and if (rows == 0) then alertLabel.Visible = true;
alertLabel.Text = "Blah blah"

Where an alertLabel is merely an invisible label you hide in your
screen to display only upon empty resultant sets.

Hi,

I need o create it at runtime and I am having a few problems. On my
GridView ITemplate I have the following:

      Dim edtPost As New TemplateField
      edtPost.ItemTemplate = New edtPost(ListItemType.Item)
      gvPosts.EmptyDataTemplate = edtPost

edtPost is a class as follows:


    ' edtPost
    Private Class edtPost
      Implements ITemplate

      Private Type As ListItemType

      Public Sub New(ByVal type As ListItemType)
        Me.Type = type
      End Sub ' New

      Public Sub InstantiateIn(ByVal container As Control) Implements
ITemplate.InstantiateIn

        ' Select template type
        Select Case Me.Type

          Case ListItemType.Item                    ' Item template

            Dim l As New Label
            l.Text = "No Records Found"
            container.Controls.Add(l)

        End Select

      End Sub ' InstantiateIn

    End Class ' edtPost


I am getting the error:

Unable to cast object of type
'System.Web.UI.WebControls.TemplateField' to type
'System.Web.UI.ITemplate'.

On code line:

gvPosts.EmptyDataTemplate = edtPost

How can I solve this?

Thanks,

Miguel
