I have a grid that if it is empty I want to open up an insert form on page load and fill in some default values.

Most of the code works except for this.

rgvAgmtUsers.Items[0].FireCommandEvent("InitInsert", string.Empty);

Now this works if there is already a record in the grid, but if the grid is empty then it doesn't work.

after this is supposed to fire I am wanting to use the grd.MasterTableView.GetInsertItem() to grab controls and set default values.

Any ideas?

Thanks,

Dustin

Multiple dropdownlis filters

I am trying to set up a RadGrid with multiple dropdownlist filters but I get an ArgumentOutOfRangeException on the MyCustomFilteringColumn

Here is code from the MyCustomFilteringColumn
:
Protected Overloads Overrides Sub SetupFilterControls(ByVal cell As TableCell)
MyBase.SetupFilterControls(cell)
cell.Controls.RemoveAt(0)
Dim list As New DropDownList()
list.ID = "list" + Me.DataField
list.AutoPostBack = True
AddHandler list.SelectedIndexChanged, AddressOf list_SelectedIndexChanged
cell.Controls.AddAt(0, list)
cell.Controls.RemoveAt(1)
list.DataTextField = Me.DataField
list.DataValueField = Me.DataField
list.DataSource = _listDataSource
list.DataBind()
End Sub

My RadGrid columns are setup like the below (here is one of the many that I have):

<custom:MyCustomFilteringColumn DataField="AssessmentID" FilterControlAltText="Filter AssessmentID column"
FilterControlWidth="80px" HeaderStyle-Width="80px" ItemStyle-Width="80px" ItemStyle-ForeColor="Black"
HeaderStyle-Wrap="true" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains"
ShowFilterIcon="false" HeaderText="Assessment ID" SortExpression="AssessmentID"
UniqueName="AssessmentID" />

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
For Each column As GridBoundColumn In RadGrid1.MasterTableView.Columns
If TypeOf column Is MyStuff.MyCustomFilteringColumn Then
CType(column, MyStuff.MyCustomFilteringColumn).ListDataSource = GetFilterTable(column.DataField)
End If
Next
end sub

Private Function GetFilterTable(ByVal Field As String) As DataTable
Dim strConnection As String = ConfigurationManager.ConnectionStrings("PKLConnectionString").ConnectionString
Dim objConnection As New SqlConnection(strConnection)
Dim SQLCmd As New SqlCommand() 'The SQL Command
objConnection.ConnectionString = strConnection 'Set the Connection String
objConnection.Open() 'Open the connection
SQLCmd.Connection = objConnection 'Sets the Connection to use with the SQL Command
Dim dt As New DataTable
Dim adapter As SqlDataAdapter
adapter = New SqlDataAdapter("SELECT distinct [" + Field + "] FROM tblAssessment", objConnection)
objConnection.Open()
Try
adapter.Fill(dt)
Finally
objConnection.Close()
End Try
Return dt
End Function

Call Sub vb from javascript

Hi,

I apologize for my bad English I'll try to explain as best as possible. This is my first ticket:you can call a vb sub from javascript written on the same page.

<script type="text/javascript"> LANGUAGE="JavaScript"

      / / Open window
     OpenFabbricatiRadWindow function () {
         var wnd = $ find ("<% = Fabbricati.ClientID%>");
         wnd.setUrl ("Form_Job / radwindow_Fabbricati.aspx");
         wnd.set_modal (true);
         wnd.show ();
     }
     / / Get selected value
     Fabbricatoselect function (sender, EventArgs) {
         eventArgs.get_argument var args = ();
         if (arg) {
            Varfabbricato.value = arg.Fabbricato;
            Vargestione.value = arg.Gestione;

   Call here ************************** **************** sub Leggi'

  }
     }


</ script>

in the page vb.aspx

Protected Sub Leggi ()
         Dim query = From c In Archivio.Tabelle_Spesa
         In joins and Archivio.Stato On c.Tab_Stato Equals e.Id_Stato
         Select ID_Tabella c.ID_Tabella =, Description = c.Tab_Descrizione, Acronym =c.Tab_Sigla, thousandths = c.Tab_Millesimi, State = e.Stato_Descrizione
         Query = RadGrid1.DataSource
         RadGrid1.DataBind ()

     end Sub

Thank

{

RadDateInput dt_ocorrencia = (RadDateInput)((item).FindControl("dt_ocorrencia"));

if (dt_ocorrencia.SelectedDate == null)

Dynamically Re-sizing Entire Grid

Hi, I have a wizard running as part of a custom add-in for Outlook 2010. In one of the wizard dialogs I have a Telerik GridView control. The wizard dialog window that contains the Grid is re-sizable and I would like to have the Telerik Grid dynamically resize as the user re-sizes the Wizard dialog.

Any suggestions on how to achieve this would be greatly appreciated.

Thanks

Dynamically created combo box losing value after multiple postbacks

I've run into a problem using the asp.net ajax RadComboBox that is dynamically added to the page, which is caused by it losing its value if more than one postback occurs.

I select an item in the combobox and then trigger a postback. After the first postback the initially selected value is still selected, but after a second postback it is not. The old style RadComboBox and the built in DropDownList both retain their selected value.

Here's a simple test example that shows the problem. The aspx simply contains a repeater with a placeholder inside it.

    
                    <asp:ScriptManager ID="scriptManager" runat="server"></asp:ScriptManager> 
        
                    <asp:Repeater ID="repTest" runat="server"> 
        
                        <ItemTemplate> 
        
                            <div> 
        
                                <asp:PlaceHolder ID="plcTest" runat="server"></asp:PlaceHolder> 
        
                            </div> 
        
                        </ItemTemplate> 
        
                    </asp:Repeater> 
        
                    <asp:Button ID="btnTest" runat="server" Text="PostBack" />

In the ItemDataBound event handler the combo boxes are created and added to the placeholder. If I select Item 2 in each combo box and then click the button twice then at the end the first two combo boxes still have Item 2 selected but the asp.net ajax RadComboBox has reverted to Item 1.

RadGrid: Drag and Drop doesn't work when we have a vertical scroll bar.

Hi,

I have a RadGrid with Items Drag-and-drop functionality. It works great unless I have more than 6 rows which allows a vertical scroll bar in the grid. When I have a vertical scroll bar and try to drag the last item/row to the first or second row, it doesn't work. I have attached snap shots and code.

Looks like the issue is with IE8 Browser.

Please help.

Thanks
