ListBox doesn't fire oninserting and oninserted events

Hi,
I have two list boxes inside a RadComboBox. RadListBoxSource is bound to an ObjectDataSource that load the listbox with names. The RadListBoxDestination is not bounded to anything, it just accepts the values that I select to transfer. The problem I am having is that when I select an Item from the RadListBoxSource, I break inside its ontransferring and ontransferred without ever breaking inside the RadListBoxDestination's oninserting and oninserted events.

I have witnessed the flow looking at the transfer demo and see that all the mentioned events get called; however, two do not get called.

Any Help will be appreciated.

Thanks in advance,
Gary

Column's values are disappearing

Hi.
A column's values in a grid are disappearing when the user is doing something on the web-site, like push a button or insert an item in another grid but not when user is inserting a new item in the grid that keep the column that lose it's values. When I refresh the grid, the values are coming back. The column is keeping a bool value from the database that is displaying as text (and as a combobox when inserting items). The code is:

<telerik:GridTemplateColumn HeaderStyle-Width="195px" DataField="Shipregistry" HeaderText="Skipsregister" SortExpression="Shipregistry" UniqueName="Shipregistry">

<ItemTemplate><%#DataBinder.Eval(Container.DataItem, "Shipregistry")%></ItemTemplate>

<EditItemTemplate>

<telerik:RadComboBox DataTextField="Shipregistry" DataValueField="Shipregistry" ID="ShipregistryComboBox" HighlightTemplatedItems="true" EmptyMessage="Velg et element..." AllowCustomText="true"

runat="server" Height="50px" Width="95px" SelectedValue='<%#Bind("Shipregistry") %>' AutoPostBack="true">

<Items>

<telerik:RadComboBoxItem runat="server" Text="norsk" Value="NOR"/>

<telerik:RadComboBoxItem runat="server" Text="internasjonalt" Value="NIC"/>

</Items>

</telerik:RadComboBox>

<asp:RequiredFieldValidator runat="server" ErrorMessage="*" ForeColor="Red" ControlToValidate="ShipregistryComboBox" ID="RequiredFieldValidator2"></asp:RequiredFieldValidator>

</EditItemTemplate><HeaderStyle Width="195px"></HeaderStyle>

</telerik:GridTemplateColumn>

protected void RadGridFerryReg_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem && e.Item.DataItem is Ferry)

{

   var item = e.Item as GridDataItem;
               var ferry = e.Item.DataItem as Ferry;
               item["Shipregistry"].Text = ferry.Shipregistry == "NOR" ? "norsk" : "internasjonalt";

}

Anyone have an idea why this happens? Perhaps the content is wrong in the ItemTemplate ....

The specified module could not be found

Hi,

I'm working with Performance Center from HP and apparently they use the telerik component. Since last week I get an error that applies on the raduploadmodule of Telerik. I also contacted HP support but they are not progressing on this so I'm trying to directly check for help on this forum. I'm admin on the server where Performance Center is running on so I have the rights to do anything ;)

Who can help or point me to the solution?

Thanks,
Nico

Problem with Filtertemplate

Hallo,

I have got a problem with the example on Example.

Because of this, i edited my code as following:

<telerik:RadGrid runat="server" ID="Grid_Statistik" AllowMultiRowEdit="false" Skin="Office2007"

GridLines="None" PageSize="20" AllowPaging="true" DataSourceID="Grid_Statistik_DataSource" AllowSorting="true" ShowStatusBar="true" >

<ExportSettings FileName="File" OpenInNewWindow="True">

<Pdf PaperSize="A4" PageHeight="210mm" PageWidth="297mm" />

</ExportSettings>

<GroupPanel ID="GroupPanel" Text="Gruppierungsfläche">

</GroupPanel><%----%>

<MasterTableView Name="Grid_Statistik" runat="server"DataSourceID="Grid_Statistik_DataSource"

AutoGenerateColumns="false" PageSize="20" AllowPaging="true" AllowMultiRowEdit="false" AllowFilteringByColumn="True">

<RowIndicatorColumn>

<HeaderStyle Width="20px" />

</RowIndicatorColumn>

<ExpandCollapseColumn>

<HeaderStyle Width="20px" />

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn HeaderText="Employee" UniqueName="Employee"

DataField="Employee" DataType="System.String" ReadOnly="True">

<FilterTemplate><%--DataSourceID="MA_Source" DataTextField="nameKomplett" DataValueField="hr_m_personal_id" --%>

<telerik:RadComboBox id="cbx_MA" runat="server" Skin="Office2007" OnLoad="cbx_MA_Load"

SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("Employee").CurrentFilterValue %>' OnClientSelectedIndexChanged="EmployeeIndexChanged"><%----%>

</telerik:RadComboBox>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function EmployeeIndexChanged(sender, args) {

var tableView = $find(<%# TryCast(Container,GridItem).OwnerTableView.ClientID %>");

tableView.filter("Employee", args.get_item().get_value(), "EqualTo");

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

<HeaderStyle Width="250px" />

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<ClientSettings>

<Scrolling ScrollHeight="415px" AllowScroll="True" UseStaticHeaders="true" />

</ClientSettings>

<PagerStyle AlwaysVisible="true" />

<HeaderContextMenu EnableTheming="True">

<CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>

</HeaderContextMenu>

<FilterMenu EnableTheming="True">

<CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>

</FilterMenu>

</telerik:RadGrid>

If I use the RadComboBox to edit my filtervalue, my browser returns the following errorcode:
"tableView is null"
Because I used the code of the example, it might be a copy paste problem, but I don't see the mistake.....

Best regards

Hiding RadProgressArea on completed with AJAX

http://www.telerik.com/help/aspnet-ajax/upload-custom-progress-monitoring-with-ajax.html

I am wanting to auto-hide the RadProgressArea on completion using AJAX - it does this automatically with a postback, but within an UpdatePanel, it just stays open after completion.
Referring to the above link, I have tried wrapping the RadProgressArea inside the UpdatePanel as well as not. I am having trouble with hiding the RadProgressArea on completion. I am using a Custom Progress, measuring a foreach loop and not uploading files.
How am I supposed to hide the RadProgressArea on completion? I have tried on client-side via the .hide() function and OnClientProgressUpdating event but this hides it as soon as it appears - before it's complete.

Thanks

Export Grid within UpdatePanel

Hi,

I have an RadGridView within an UpdatePanel and I want to export it to Excel. Than I discover a problem. I've already knew that Button which triggers the actual export should be registered as an postback control. I did it (according to the way found on telerik website). But it does not work. My GridView looks like this

    
               <telerik:RadGrid ID="gvSearchTelerik" runat="server" 
        
                                     OnItemCreated="gvSearchTelerik_ItemCreated" 
        
                                     EnableAjaxSkinRendering="false" 
        
                                     AllowSorting="True" 
        
                                     AllowPaging="True" 
        
                                     PageSize="15" 
        
                                     GridLines="None" 
        
                                     Width="100%" 
        
                                     AllowFilteringByColumn="True" 
        
                                     DataSourceID="sqlSearchDevice" 
        
                                     HeaderStyle-Wrap="false" 
        
                                     HeaderStyle-Width="150px" 
        
                                     ShowGroupPanel="True" 
        
                                     ShowStatusBar="true"> 
        
                            <MasterTableView CommandItemDisplay="Top"> 
        
                                <CommandItemTemplate> 
        
                                    <asp:ImageButton ID="bXls" runat="server"

                                    <telerik:GridBoundColumn DataField="Id" DataType="System.Int32" 
        
                                                             HeaderText="MojeIdecko">

                            <PagerStyle Mode="NextPrevAndNumeric"></PagerStyle> 
        
                            <ExportSettings IgnorePaging="true" OpenInNewWindow="true" ExportOnlyData="true" > 
        
                                <Excel FileExtension="xls" Format="ExcelML" /> 
        
                            </ExportSettings>                          
        
                        <ClientSettings AllowDragToGroup="True" 
        
                                        AllowColumnsReorder="true" 
        
                                        ReorderColumnsOnClient="true"> 
        
                            <Scrolling AllowScroll="True" 
        
                                       UseStaticHeaders="True" 
        
                                       SaveScrollPosition="true"

                        </ClientSettings>                          
        
                    </telerik:RadGrid>

it is placed in the content page of a master page. Update panel is placed over the whole content in the master page. The code behind of the export function is

    
                protected void bXls_Click(object sender, ImageClickEventArgs e)  
        
                {  
        
                    gvSearchTelerik.ExportSettings.ExportOnlyData = true;  
        
                    gvSearchTelerik.ExportSettings.IgnorePaging = true;  
        
                    gvSearchTelerik.ExportSettings.OpenInNewWindow = true;  
        
                    gvSearchTelerik.MasterTableView.ExportToExcel();  
        
                }

i registered the button as postback control in the ItemCreated event of the gridview

    
                protected void gvSearchTelerik_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e) 
        
                { 
        
                 if (e.Item is GridCommandItem) 
        
                   { 
        
                       ImageButton ibExportToExcel = (e.Item as GridCommandItem).FindControl("bXls") as ImageButton; 
        
                       this.RegisterPostbackControl(this, ibExportToExcel); //this function just registers input control

            // via ScriptManager placed on the MasterPage

                   } 
        
                }

however, each time i click the export button an asynchronous postback is made, not just fullpostback and GridView is not exported.
I tried other solution written on the telerik website, but non of them seem to work. What I've discovered was fact that export is made only for the first time. In other words, export is working, but when i made some postback on the page, export button does not cause full postback anymore.

please help.

thanks
