I have a RadGrid with the property UseStaticHeaders = true for freezing the header row while scrolling.
but when i set this property to true Width of Headers does not match the corresponding Column Header Width while setting that property to false keeps headers and columns width match. How can i have frozen headers matching columns width?

GridDateTimeColumn Filtering In IE7 Will Hide the Filter Icon After Filtering

After being unable to resolve this issue with my own code, I tried running the demo site in IE7. To my surprise, it has the same issue.

Steps to Recreate

Go to: http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/filtering/defaultcs.aspx
Filter by shipped date: enter a date or use the date picker, click on the associated filter icon
View the results...

It appears as if the filter icon is behind the date picker icon.

Filtering in hyperlinks

Hi,

We have a hyperlink in the radgrid and unfortunately the filtering doesn't work.
The following ASPX code have been used:

<telerik:GridHyperLinkColumn HeaderText = "Discussion Name" DataTextField="Discussion_Name"
ItemStyle-HorizontalAlign="Left" UniqueName="Discussion_Name"
DataNavigateUrlFields="Discussion_Id" SortExpression="Discussion_Name" ItemStyle-Width="320"
DataNavigateUrlFormatString="Observation.aspx?Id={0}">
</telerik:GridHyperLinkColumn>

Any ideas why is this?

Thanks!

Why does this not work?

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

Annulla modifiche

if (ckbItem.Checked == true && ckbItem.Enabled == true)

{

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

if (dt_ocorrencia.SelectedDate == null)

{

erro = true;

}

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
Gary
