RadAjaxLoadingPanel stop animation/loading with server side code

Hi Forum.

I would like to know a way to stop a radajaxloadingpanel animation/loading with vb(if possible, if not c#?). My problem is the following: hen i hit a button a serie os validations are made, if validation returns false i want o show a tooltip showing some information, while doing the validation i want the radajaxloadingpanel to appear with animation/loading so the person can know that something is happening. From what i can understand, the problem here is that the end of the radajaloadingpanel animation/loading makes a postback of some sort witch makes the tooltip to hide. i tried 2 ways:

1º

If Valido_Dados_Processos(novo_proceso) = True Then

If MessageBox.Show("Tem a certeza que pretende criar um novo processo?", "Criação de processo", MessageBoxButtons.YesNo) = Windows.Forms.DialogResult.Yes Then

If

Existe_boletim_compProc(rmtb_procesocompanhia.TextWithLiterals, rmtb_apolice.TextWithLiterals, rcb_sinistrado.SelectedValue)

Then

Altera_Processo()

Else

Gravar_novo_Processo()

End If

Else

rtt_info_on_error.Visible = True

rtt_info_on_error.Show()

End If

2º

Protected Sub Page_LoadComplete(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.LoadComplete

If valido_op_processo = False Then

rtt_info_on_error.Visible = True

rtt_info_on_error.Show()

valido_op_processo = True

End If

End Sub

Protected Sub rb_alterar_proceso_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles rb_alterar_proceso.Click

If Valido_Dados_Processos(grava_proceso) = True Then

If MessageBox.Show("Tem a certeza que pretende alterar o processo?", "Alteração de dados", MessageBoxButtons.YesNo) = Windows.Forms.DialogResult.Yes Then

If

Existe_boletim_compProc(rmtb_procesocompanhia.TextWithLiterals, rmtb_apolice.TextWithLiterals, rcb_sinistrado.SelectedValue)

And aux_boletimID <> "" Then

Altera_Processo()

Else

Gravar_novo_Processo()

End If

Else

valido_op_processo = False

End If

End Sub

None of them worked, so if anyone could help me i would appreciate very much

Many thanks,
FEST

In a prior test i moved the logic to the PreRender event, but the event registration for the radButton does not work in this case.
Can you please point me to the right direction.

I've include the picture showed the Grid in Detail Table of the master Grid. If user click on the checkbox on the Master Grid, Grid in Detail Table should be ENABLED.

Thank you.

centralizing loading sign

Hi,
I have a page consists of two grids. The bigger one is located in the center of screen, the other is smaller one which is placed at the rigth top corner. I have a template column including a button in bigger and centered grid. When it clicked some ajax code is executed. If I define
ajax setting as follows both of the grids are refreshing. But I only need smaller one to be refreshed. If I remove the the bigger one's config item from UpdatedControls section "Loading" sign is seems in the center of smaller grid. But I want the sign to be in the center og bigger grid. How can I do it? Refreshing two grids causes performance problem even there is no need.
Thank you,

Accessing Controls in RadListView not working

Under the RadListView you suggest the following:

RadControls for ASP.NET AJAX

Accessing controls in the LayoutTemplate

To get reference to a control in RadListView LayoutTemplate you can use its FindControl(controlId) method.

CopyC#

protected void RadListView1_PreRender(object sender, EventArgs e)
{
    Label lbl = RadListView1.FindControl("Label1") as Label;
}

I can't make it work. 
My code:
<telerik:RadListView ID="RadListView1" runat="server" AllowPaging="True"
    ItemPlaceholderID="PlaceHolder1" onitemcreated="RadListView1_ItemCreated"
    onprerender="RadListView1_PreRender" >
    <LayoutTemplate>
        <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
    </LayoutTemplate>
    <ItemTemplate>
        <div style="float: left;">
            <fieldset style="border: 0; width: 154px; height: 154px; margin: 5px 5px 5px 5px;">
                <div class="myClass" style="padding: 2px 2px 2px 2px; background: #eeeeee; text-align: center;">
                    <telerik:RadBinaryImage ID="RadBinaryImage1" runat="server" AutoAdjustImageControlSize="False"

                        ToolTip="Click to view preview" Width="150px" Height="150px" />
                </div>
            </fieldset>
            <div style="border: 0px; white-space: normal; width: 150px; margin: 5px 5px 5px 5px;
                padding: 2px 2px 2px 2px;">
                <asp:CheckBox ID="chkImage" runat="server" AutoPostBack="True" />
                <asp:HyperLink ID="lnkAsset" Target="_blank" NavigateUrl='javascript:void(0);' runat="server"><%# Eval("filename") %></asp:HyperLink>
                <asp:HiddenField ID="hiddenAssetId" Value='<%# Eval("id") %>' runat="server" />
            </div>
        </div>
    </ItemTemplate>
    <EmptyDataTemplate>
        No Assets Found
    </EmptyDataTemplate>
</telerik:RadListView>
Code behind:
protected void RadListView1_PreRender (object sender, EventArgs e)
{
    HyperLink lnkAsset = RadListView1.FindControl ("lnkAsset") as HyperLink;
    lnkAsset.Attributes.Add ("OnClick", "javascript:void(assetInfoPopUp(assetId));return false;");
}lnkAsset is null.
