AjaxLoadingPanel not showing when invoking user control

I have the following situation: rad grid is updated when event is passed from a user control on the same page, while AJAX loading works fine, and reloads the grid properly, the RadAjaxLoadingPanel does not show.

here is the simplified example of the aspx page.

    
            <%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %> 
        
            <%@ Register src="../../PageControls/Filters/TradeFilter.ascx" tagname="TradeFilter" tagprefix="uc1" %> 
        
            <telerik:RadAjaxManager DefaultLoadingPanelID="RadAjaxLoadingPanel1" ID="RadAjaxManager1" runat="server"> 
        
                <AjaxSettings> 
        
                    <telerik:AjaxSetting AjaxControlID="filterTrade"> 
        
                        <UpdatedControls> 
        
                            <telerik:AjaxUpdatedControl ControlID="grdTrades" LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                        </UpdatedControls> 
        
                    </telerik:AjaxSetting> 
        
                </AjaxSettings> 
        
            </telerik:RadAjaxManager> 
        
            <telerik:RadAjaxLoadingPanel BackColor="Gray" ID="RadAjaxLoadingPanel1" runat="server" Height="150px" Width="150px" Transparency="25"> 
        
                    <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>' style="border:0;" /> 
        
            </telerik:RadAjaxLoadingPanel> 
        
            <uc1:TradeFilter ID="filterTrade" runat="server" /> 
        
            <telerik:RadGrid ID="grdTrades" runat="server" Skin="Web20" EnableViewState="true"> 
        
            <MasterTableView  autogeneratecolumns="true" > 
        
            </telerik:RadGrid>

As i said, the grid loads properly using AJAX and not refreshing the page, but RadAjaxLoadingPanel1 is not displayed.
If I have grid that is refreshed by aspx control, it is displayed properly.

PageMethod bound Grid with FilterTemplates

I have a grid that is using declarative client side binding to a aspx pagemethod to get data which works fine.

<telerik:RadGrid ID="rgDiscoveries"

runat="server"

AllowFilteringByColumn="True"

AllowSorting="true"

AllowPaging="True"

GridLines="None"

AutoGenerateColumns="true" Culture="en-GB">

<ClientSettings>

<DataBinding Location="Default.aspx" SelectMethod="GetDataAndCount" />

</ClientSettings>

...

I have added a FilterTemplate to one column which has a ComboBox in which pulls a listing from a second page method.

<telerik:GridBoundColumn DataField="ScriptName"

HeaderText="Script Name"

UniqueName="scriptName"

DataType="System.String">

<FilterTemplate>

<telerik:RadComboBox ID="filterScriptName"

runat="server"

EmptyMessage="Select a script"

EnableLoadOnDemand="true"

ShowMoreResultsBox="true"

EnableVirtualScrolling="true"

OnClientSelectedIndexChanged="filterScriptName_SelectedIndexChanged">

<WebServiceSettings method="GetScriptNames" Path="Default.aspx" />

</telerik:RadComboBox>

</FilterTemplate>

</telerik:GridBoundColumn>

The combobox is populated but I don't know how to trigger the grid to repopulate when the combobox SelectedIndexChanged event fires.

function filterScriptName_SelectedIndexChanged(sender,args) {

var tableView = $find("<%= rgDiscoveries.MasterTableView.ClientID %>");

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

// What goes here??

}

Is there an example of this somewhere please?

Cheers,
Nick

radgrid filter issue

Hi,

I am filtering the grid on a numeric field using the column filter. When filtered with '6 7' filter value and filter options other than between, I get '...operand missing..' error. Can you provide a way to trap the error?

Thanks & Regards

Must be easy - get rowcount when less than 1 page

Hi - on my grid, it displays the total number of results as well the normal pagination controls, but, if I have my grid set to display 50 rows per page and I have less than 50 results, the pagination doesn't show (which is obvious) but the total row count doesn't show either.

How would I get it to display, say 35 when I have it set to 50 rows per page?

Thanks.

Radgrid insert/update missing values

Hi all,

I write this just to save some of you some frustrating hours.

If one of your gridcolumns contain a '$' character in the UniqueName property, there is a risk that you are not able to get the new/updated value from that column.
I have spent many (!) hours trying to figure out what the problem was.
I don't know if it always is so, or if it was a a combination of dropdown columns / dynamic creation etc ... - but it did not work.

As soon as I removed the '$' - everything was ok.

According to Telerik support this is not a bug - so I guess nothing will be changed due to this in future versions.

Now you are warned !

Happy programming ;-)

Thanks.

Adding an item that's not in the datasource

I'm using a sql datasource to populate my radcombobox. The combobox is a multiselect with checkboxes. I would like to add another item, the text would be All and if you select this item, all the checkboxes in the combo would be selected. I tried in the databound event and it makes the checkbox, but not the text. Here's the code:

protected void ImpactCombo_DataBound(object sender, EventArgs e)

{

RadComboBoxItem all = new RadComboBoxItem("All", "-1");

ImpactCombo.Items.Add(all);

}

Any ideas? Thanks.

Need Help - MasterPage > WindowManager > UserControl

Hello Everyone,

I have been searching for an hour trying to find the solution to this issue.

I am trying to access a RadWindow from a RadWindowManager on a MasterPage within a UserControl.
So...

MasterPage >> WindowManager >> UserControl >> RadWindow

MasterPage
-----------------------

<telerik:RadWindowManager ID="RadWindowManager1" runat="server">

</telerik:RadWindowManager>

UserControl
-------------------------

<

style type="text/css">

.style1

{

width: 32px;

height: 32px;

}

</

style>

<

p>

<img alt="" class="style1"

src="../../images/ui/1290451133_x-office-document.png" /></p>

<

telerik:RadWindow ID="RadWindow1" runat="server">

<

ContentTemplate>

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

</

ContentTemplate>

</

telerik:RadWindow>

OnClick of the <IMG> tag I would like to load this RadWindow into the RadWindowManager collection (display it).

What is the best way to achieve this functionality?

Also, is there a way to load a UserControl within the RadWindow?

Many thanks,
~Dean

Reset Sorting from clientside

Is it possible? I have tried

from http://www.telerik.com/help/aspnet-ajax/grid_sort.html

var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();

masterTable.sort("");

but it does not seem to do anything?

I need to do it from client side as when you click on different nodes in in my treeview it will rebinds the grid to different columns, so it needs to clear the column sort at the same time.

thanks
Toby
