Hi,

I am trying to reset the value set in a combobox of a ComboBox used in a UserControl.

UserControl looks like that :

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="UserControl.ascx.cs" Inherits="UserControls.UserControl" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<telerik:RadComboBox ID="comboBox" runat="server"
EnableVirtualScrolling="false" EnableTextSelection="true" MaxHeight="250px"
AllowCustomText="False" MarkFirstMatch="false" ShowMoreResultsBox="true"
Filter="Contains" EnableLoadOnDemand="True" Sort="Ascending" Width="280px"
OnItemsRequested="comboBox_ItemsRequested" AutoPostBack="True"
OnSelectedIndexChanged="comboBox_SelectedIndexChanged" CausesValidation="false"
ZIndex="1000" ontextchanged="comboBox_TextChanged"></telerik:RadComboBox>
</span>

When I try to call the ClearSelection of the comboBox in default.aspx like that :

<html>
<body onload="Load()" >
<uc1:UserControl ID="cboComboBox" runat="server" Width="95%" MaxHeight="175px" />
</body>
</html>
<script type="text/javascript">
function Load() {
var cboComboBox= document.getElementById('<%=cboComboBox.FindControl("comboBox").ClientID%>');
cboComboBox.clearSelection();
}
</script>

I keep getting the error "Method undefined"

Any idea why ?

Thanks,

Guillaume

Please suggest on this.

Problem with rebind method

I'm experiencing a problem where my code calls the rebind method, and this throws an exception for a reason I cannot figure out.

The exception it throws is: " System.Data.DataRowView' does not contain a property with the name 'post_flag' " It throws this error even when it does not delete the cell and simply rebinds it.

Here are the attributes of the grid:
<telerik:RadGrid ID="_ExpGrid" runat="server" AllowPaging="True" PageSize="15" AutoGenerateColumns="false"
Width="1700px" CellSpacing="4" Skin="Web20" OnItemCreated="_ExpGrid_ItemCreated" AllowSorting="true"
OnDeleteCommand="_ExpGrid_DeletedCommand" OnPageIndexChanged="_ExpGrid_SelectedIndexChanged">

Here is the delete method:

if (IsPostBack)
{
Service.ServiceClient client = new Service.ServiceClient(ConfigurationManager.AppSettings["ServiceBinding"]);

GridDataItem dataItem = (GridDataItem)e.Item;
int id = Convert.ToInt32(dataItem.GetDataKeyValue("Expense_ID"));
client.DeleteTrans(id);
_ExpGrid.Rebind();
}

This is the line that throws an exception:
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Convert.ToBoolean(Eval("POST_FLAG")) %>' Enabled="false" />

<telerik:RadButtonToggleState PrimaryIconUrl="images/radio6-off.png" />

</telerik:RadButton>

If I use PrimaryIconUrl, page doesn't show in my page. But if I use SecondaryIconUrl page show icon but right side. I want put icon left side of text but PrimaryIconUrl doesn't work. No image shown if I use PrimaryIconUrl.

How can I fix it?

RadAjaxLoadingPanel freezing in RadScheduler AdvancedEditForm

Hi,

I have a ASP.NET page with a RadScheduler on it.
The page references a user control for the menu on the top of the page. The user control does not have an AjaxManager on it.

I have a RadAjaxManager on the main page.

When the page loads and you click on a calendar appointment the advancededitform appears correctly.
But if you try to cancel out of the AdvancedEditForm the LoadingPanel freezes.

I have another page in the application that uses a RadScheduler and it works fine. But that page does not reference any user controls.

If I set EnableAjax=false for this RadAjaxManager everything works fine.

In the Chrome debugger I get his error while the loading panel is freezing.
Uncaught TypeError: Cannot read property 'parentNode' of undefined.

Any ideas what would cause this?

Thanks,

Kevin

ASP.Net AJX OnLine Demos Not working

When
I attempt to access the on-line demos for the various product located at
demos.telerik.com are either not responding at al and timeout or take a long
time to respond. In particular, the demo for the dock controls does not work at
all. I need to access this information as I am working on a project using this
control.

The same thing happens when I place a control on a page, right mouse click on the
control and attempt to navigate to the specific control demo. The information
in the demos is helpful (more that the help files) .

My customer ID is EU1330672.
