[Solved] RadAjaxManager to update label control

Hi!

I have a doubt. In my page I use RadAjaxManager when I have an action in my RadGrid and, independent or not of exception, I would like to show a message in a label. The code you can see below:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
<AjaxSettings>
    <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="rgVeiculos" LoadingPanelID="RadAjaxLoadingPanel1" />
        </UpdatedControls>
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="rcbVeiculo" LoadingPanelID="RadAjaxLoadingPanel1" />
        </UpdatedControls>
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="rcbClassificacao" LoadingPanelID="RadAjaxLoadingPanel1" />
        </UpdatedControls>
    </telerik:AjaxSetting>

    <telerik:AjaxSetting AjaxControlID="rgVeiculos">
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="rgVeiculos" LoadingPanelID="RadAjaxLoadingPanel1" />
        </UpdatedControls>
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="trMensagem" LoadingPanelID="RadAjaxLoadingPanel1" />
        </UpdatedControls>
    </telerik:AjaxSetting>

    <telerik:AjaxSetting AjaxControlID="btnBuscarVeiculos">
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="rcbVeiculo" LoadingPanelID="RadAjaxLoadingPanel1" />
        </UpdatedControls>
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="rcbClassificacao" LoadingPanelID="RadAjaxLoadingPanel1" />
        </UpdatedControls>
    </telerik:AjaxSetting>

    <telerik:AjaxSetting AjaxControlID="btnBuscarClassif">
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="rcbClassificacao" LoadingPanelID="RadAjaxLoadingPanel1" />
        </UpdatedControls>
    </telerik:AjaxSetting>

</AjaxSettings>
</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Telerik" >
</telerik:RadAjaxLoadingPanel>

I will put the code of RadGrid:
                        <telerik:RadGrid ID="rgVeiculos" Width="100%" Skin="Telerik"
                            runat="server" AllowPaging="true" AllowSorting="true"
                            GridLines="None" AutoGenerateColumns="false" PageSize="20"
                            OnItemCreated="rgVeiculos_ItemCreated"
                            OnNeedDataSource="rgVeiculos_NeedDataSource"
                            OnDeleteCommand="rgVeiculos_DeleteCommand">
                            <MasterTableView GridLines="None" DataKeyNames="IdFrotaModelo" Name="TableViewVeiculos">
                                <Columns>
                                    <telerik:GridBoundColumn UniqueName="Fabricante" HeaderText="Fabricante" DataField="Fabricante" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left"></telerik:GridBoundColumn>
                                    <telerik:GridBoundColumn UniqueName="Veiculo" HeaderText="Veículo" DataField="Veiculo" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left"></telerik:GridBoundColumn>
                                    <telerik:GridBoundColumn UniqueName="Classificacao" HeaderText="Classificação" DataField="Classificacao" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left"></telerik:GridBoundColumn>
                                    <telerik:GridBoundColumn UniqueName="Categoria" HeaderText="Categorias Habilitação" DataField="Categorias" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left"></telerik:GridBoundColumn>

                                    <telerik:GridTemplateColumn UniqueName="TemplateEditColumn">
                                        <ItemTemplate>
                                            <asp:HyperLink ID="EditLink" runat="server" Text="Editar"></asp:HyperLink>
                                        </ItemTemplate>
                                    </telerik:GridTemplateColumn>
                                    <telerik:GridButtonColumn UniqueName="DeleteColumn" Text="Remove" CommandName="Delete" ConfirmTitle="Exclusão" ConfirmText="Deseja realmente excluir este veículo?" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left" HeaderStyle-Width="60px"></telerik:GridButtonColumn>
                                </Columns>
                            </MasterTableView>
                        </telerik:RadGrid>

I will put the code I use for label:
                <tr id="trMensagem" runat="server" visible="false">
                    <td valign="middle">
                        <asp:Panel ID="pnlMsg" runat="server" BackColor="#FFFFAA" Height="25px">
                              <asp:Label ID="lblResultado" runat="server" Text="" Font-Names="Verdana" Font-Size="9"></asp:Label>
                        </asp:Panel>
                    </td>
                </tr>

So, If I try to remove some item of my grid, I would like to show a message for the user, but nothing occur in a page. In a code behind, I try something like this:

trMensagem.Visible = true;
lblResultado.Text = "Message for user";

Someone know how I can overcome this problem?

Radgrid and javascript question

Hello everyone,

Here is my situation.

1. Using a RadGrid.
2. Using a EditForm template.
3. In the edit form template i have a RadCalendar and a Listbox.
4. In the list box i have a series of dates that i want to use to select dates in the RadCalendar.
5. I want to use the RadCalendar to select dates.. and have it put into the listbox.
6. I can see the RadCalendar in Javascript.. i can add/remove elements etc but I am having a hell of a time getting the javascript to see the listbox (so that i can update it).

Here is the code so far (work in progress)

function getElements(calendarInstance, args) {

1 var grid = $get('<%= grdElectives.ClientID %>');

2 alert(

'gridElectives found: ' + grid);

3 var dates = calendarInstance.get_selectedDates();

4 var i = 0;

5 for (i = 0; i < dates.length; i++) {

6 alert(dates[i]);

7 }

8 var todaysDate = new Date();

9 var todayTriplet = [todaysDate.getFullYear(), todaysDate.getMonth() + 1, todaysDate.getDate()];

10 var tomorrowTriplet = [todaysDate.getFullYear(), todaysDate.getMonth() + 1, todaysDate.getDate() + 1];

11 var selectedDates = [todayTriplet, tomorrowTriplet];

12 calendarInstance.selectDates(selectedDates,

true);

}

Line 1 gets the grid instance correctly (as line 2 is showing Grid Electives found: OBJECT in the alert box)
But i need to find the listbox control that is within that grid (the name of the listbox is lstDates)
I know that once i have an instance of the listbox i can read/write to it.... which is what i need to do despirately

Cannot for the life of me get this to work.

Any help is appreciated.

Writing Text

Hello,

At what point in the process does the RadSpell control actually write the updated content to the textbox? I'm trying to, when the spell check has finished, post back to the server with the updated content. The postback works, but the content is not correct... so at what point is the content written back to the control that was spell checked?

And is there a property on the spell check control that stores the updated text?

Thanks.

Using Rad Window for "tell a friend"

I'm looking at using Rad Window for "tell a friend" on our site. There would be a link on every page that would open a Rad Window that contains a form that will email the current page Title and URL to the recipient.

My question is that I'm not sure how to pass the current page information to the form in the Rad Window.

if anyone can point me in the right direction, I'd appreciate it.

System.Web.HttpException: Response is not available in this context

Hello,

I get this after an exception in an ajax callback (using RadAjaxManager) when I try to redirect to an error page using
Ajax redirect.
My code

    
                        if ( IsInAsyncPostBack && ( AjaxManager != null ) )  
        
                        {  
        
                            if ( url.StartsWith("~/") )  
        
                                url     =   ResolveClientUrl(url);  
        
                            AjaxManager.Redirect(url);  
        
                        }  
        
                        else  
        
                            Response.Redirect(url,endResponse);

May be ajaxmanager should not get Page.Response but HttpContext.Current.Response ?

May be the idea of redirecting using ajax during a call back is bad ?
In this case how to incorporate ajax in my general errors manager which redirects to a standard error page.

Thanks for help

TextBox Width inside RadDock

Hi All,

Dynamically,I created RadDock and added an html table of 2 cells with 50% width for each.In the first cell i addel an asp.net label and asp.net textbox in the second one with100% width for each control.
In the default masterpage of sharepoint,it works fine while in another masterpage(inside sharepoint like BlueBand.master or customized one) the textbox right border becomes outside the raddock.It seems that it adds the default padding and border-width to its width because if i remove the padding and put the border width 0px then i see that the textbox becomes in the RadDock Content.
But I need the borders and the padding,also i can't put the textbox width 99% or 98%.

Is this behavior of textbox inside the RadDock an normal behavior ?

Any Help is really appreciated.

Regards,
Ahmad
