Hi Everybody

How can i display in the gridview.
"there is no data for this request" if the binded dataset is empty?

Can anyone give some ideas?

Thanks

why not check whether the DataSet has any rows in code before binding then show/hide a label with that text?

alternatively if it must appear in the grid view, why not build a data table with one column called result and add a row who's value is your text, then bind it to your grid view

If there is No Data in Gridview and we want to show a message that “No data available”.
We can do this by using the following tag in gridview.

<EmptyDataTemplate>

No Data Available

</EmptyDataTemplate>

JUST ADD THE EmptyDataText PROPERTY IN THE FOLLOWING WAY:

<asp:GridView runat="server" ID="gvCaseDetail" Width="100%" 
    EmptyDataText="there is no data for this request"
......................................

YOU CAN ALSO RENDER HTMEL TEXT LIKE:

<asp:GridView runat="server" ID="gvCaseDetail" Width="100%" 
    EmptyDataText="<table cellspacing=1 cellpadding=4 rules=rows border=0 style=color:Black;font-family:Tahoma;font-size:1em;width:730px;border-collapse:collapse;><tr style=color:Black;background-color:#00BFFF;font-weight:bold;><th scope=col>Case ID</th><th align=center scope=col>Subject</th><th align=center scope=col>Status</th><th align=center scope=col>Date</th><th align=center scope=col>Action</th></tr></table>"
..............................

ONE THING YOU HAVE TO KEEP IN MIND THAT IF YOU DIDN'T BIND ANY DATASOURCE YOU WILL GET BLANK.

Dear,

zneweb and mail2saion have solved your problem.

<asp:GridView ID="GridView1" runat="server">
            <EmptyDataTemplate>
                There is no data.
            </EmptyDataTemplate>
        </asp:GridView>

try with this. My english is poor ok?

Public Sub CheckEmptyGrid(ByVal grid As WebControls.GridView)

            If grid.Rows.Count = 0 And Not grid.DataSource Is Nothing Then
                Dim dt As Object = Nothing
                If grid.DataSource.GetType Is GetType(Data.DataSet) Then
                    dt = New System.Data.DataSet
                    dt = CType(grid.DataSource, System.Data.DataSet).Tables(0).Clone()
                ElseIf grid.DataSource.GetType Is GetType(Data.DataTable) Then
                    dt = New System.Data.DataTable
                    dt = CType(grid.DataSource, System.Data.DataTable).Clone()
                ElseIf grid.DataSource.GetType Is GetType(Data.DataView) Then
                    dt = New System.Data.DataView
                    dt = CType(grid.DataSource, System.Data.DataView).Table.Clone
                End If
                dt.Rows.Add(dt.NewRow())
                grid.DataSource = dt
                grid.DataBind()
                grid.Rows(0).Visible = False
                grid.Rows(0).Controls.Clear()
            End If
        End Sub

and the call

CheckEmptyGrid(Grid)

With this the headers appers ok

thanks for the help. I've signed in here because of that :)..
I'm a beginner at asp.net and i'll need a lot of help

there is a empty template in grid view to show message when data not available you can use it

try this

if (ds.Tables[0].Rows.Count > 0)
            {
                //bind the Data
            }
            else
            {
             lblMessage.Text = "No Data to Display";
            }

a gridview is not visible when there no data, so you need to add a label that will display the message.

There's a ShowHeaderWhenEmpty property on a GridView that shows the headers even if the datasource contains no rows.

Here's an example of how you can do

exmple

step 1 You add a method Returns an DataTable

Public Function FillGridView() As DataTable

        Dim dt As New DataTable
        Using cn As New SqlConnection("conection")

            Dim sql As String = "select * from tabla where campo =@valor"

            Dim cmd As New SqlCommand(sql, cn)
            cmd.Parameters.AddWithValue("@valor", valor)
            cn.Open()

            Dim da As New SqlDataAdapter(cmd)

            Try
                da.Fill(dt)
            Catch ex As Exception

            Finally
                cn.Close()
            End Try

        End Using

        Return dt

    End Function

step 2 Where we call the method FillGridView

Dim dts As DataTable
        dts = FillGridView()

        If dts.Rows.Count > 0 Then

            With Me.GridView1
                .DataSource = dts
                .DataBind()
            End With
        End If
