I have a gridview that is databound in the code-behind using a stored procedure.

  • 0

I have a gridview that is databound in the code-behind using a stored procedure. I am handling the Paging event in the code as well, but whenever I click on a page number, I keep getting the empty data template instead of more rows. Any suggestions?

EDIT: I am re-binding the data source of the gv after I change the page index.

Here is my code – I have a dropdown list that determines what the data source is:

Protected Sub ddlProjectForm_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlProjectForm.SelectedIndexChanged     Dim strProjectFormID As String = Me.ddlProjectForm.SelectedValue     Dim conn As New SqlConnection(WebConfigurationManager.ConnectionStrings('Conn').ConnectionString)     Dim cmd As New SqlCommand()     Dim da As New SqlDataAdapter     Dim ds As New DataSet      If strProjectFormID <> 'Select' Then         Try             Using conn                 conn.Open()                  With cmd                     .Connection = conn                     .CommandType = CommandType.StoredProcedure                     .CommandText = 'sp_GetAllFormData'                     .Parameters.AddWithValue('@projectFormID', strProjectFormID)                 End With                  da.SelectCommand = cmd                 da.Fill(ds)                  Me.gvAllSentData.DataSource = ds.Tables(0)                 Me.gvAllSentData.DataBind()                 Me.gvAllSentData.Visible = True             End Using         Catch sqlEx As SqlException             Dim newError As New ErrorLogger(Me.Page.Title, sqlEx.Message, Session('UserName'))             newError.LogError()              Trace.Write(sqlEx.Message)             Me.lblBadFeedback.Visible = True             Me.lblBadFeedback.Text = 'We're sorry - an error has occurred.  It has been logged and will be reviewed by the site admin.'         Catch ex As Exception             Dim newError As New ErrorLogger(Me.Page.Title, ex.Message, Session('UserName'))             newError.LogError()              Trace.Write(ex.Message)             Me.lblBadFeedback.Visible = True             Me.lblBadFeedback.Text = 'We're sorry - an error has occurred.  It has been logged and will be reviewed by the site admin.'         End Try     Else         Me.gvAllSentData.DataSource = Nothing         Me.gvAllSentData.Visible = False     End If  End Sub  Protected Sub gvAllSentData_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles gvAllSentData.PageIndexChanging     Me.gvAllSentData.PageIndex = e.NewPageIndex     Me.gvAllSentData.DataBind() End Sub

  1. You are rebinding an empty datasource. Your code should read:

    Protected Sub gvAllSentData_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles gvAllSentData.PageIndexChanging     Me.gvAllSentData.PageIndex = e.NewPageIndex     Me.gvAllSentData.DataSource = __The_Data_To_Bind__     Me.gvAllSentData.DataBind() End Sub
