I have found an issue where the ImageManager preview panel is caching.

This occurs when a new image replaces an old one but the preview still displays the old image.

Due to the way we recognise images on the site where the html is output to we cannot follow this post here which suggests adding a random parameter as it comes out in the RadEditor HTML view.

I have linked out to the external dialogs but I have been unable to find a location where I can change the preview image to contain the parameter in the url and not have an impact on the url returned by the image manager.

In row of RadGrid, 2 Comboboxes, unable to retrieve new value of first dropdown on Update/Insert Command

Hello everyone,

I am currently building a RadGrid that is bound to an empty dataset. In this dataset, a new row will allow a selection of parameters, which will make up a query (eventually).

Each row has two dropdowns, the first one drives the second one's value. Both values are required for the end result.
Currently, when I click "Insert new" it creates the new row, I can select a value from the first dropdown, and it populates the second. When I click "Insert" to store the data, the data stored is the original value of the first dropdown (Unique Name: ObjectName) and the selected (correct value) of Unique Name: CounterName. This problem occurs both on Update and Insert, so I suspect its the same cause.

After trying to look up values, use hash tables, etc---I have not quite figured out what I am doing wrong. Suggestions would be appreciated, I suspect its something small.

Thanks!

[Solved] Grid (inside a RadWindow) Context Menu - not working properly in Chrome

Hi,

I have a RadGrid inside a RadWindow. This RadGrid has a Context menu as well.

When I right click on a grid row the context menu displays behind the RadWindow in Chrome. But in IE and Firefox I don't have this problem.

I have set the z-index to a value more than 7000 as well.

Have anyone else seen this behaviour before?

As I mentioned the problem is only with Chrome.

Thank you.

Dropdownlist not decorated

Hi,

This will be easy for you. I have created a very simple asp.net web page with a few various controls including Telerik dropdownlist and I want all of them to be "decorated" by FormDecorator control. All controls are decorated now except the dropdownlist which looks exactly the same as before "decoration".

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager runat="server" ID="RadScriptManager1" />

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" Height="200px" Width="300px">

<telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" DecoratedControls="All" DecorationZoneID="zone" />

<div id="zone" class="formRow" style="border: 0;">

<telerik:RadDropDownList ID="RadDropDownList1" runat="server"

DataSourceID="sqlDS_Culture" DataTextField="LocalizationDesc"

DataValueField="LocalizationID">

</telerik:RadDropDownList>

<asp:SqlDataSource ID="sqlDS_Culture" runat="server"

ConnectionString="<%$ ConnectionStrings:EStoreConnectionString %>"

SelectCommand="Localization_Get" SelectCommandType="StoredProcedure">

</asp:SqlDataSource>

<table>

<telerik:RadListView ID="RadListView1" runat="server" DataKeyNames="ID" ItemPlaceholderID="CityItemsHolder" OnPreRender="RadListView1_PreRender" >

<LayoutTemplate>

<telerik:RadTextBox ID="RadTextBox1" runat="server" Text="test">

</telerik:RadTextBox>

<fieldset style="width: 300px;">

<legend>Cities</legend>

<asp:Panel ID="CityItemsHolder" runat="server">

</asp:Panel>

</fieldset>

</LayoutTemplate>

<ItemTemplate>

<tr>

<td></td>

<td style="text-align: left;">

<asp:LinkButton ID="lbnDeliveryType2Select" runat="server"

><%# eGlobalization.GetGlobalResourceObject("Localization", "DeliveryType_" & CType(Container.DataItem, eDelivery).ID).ToString%></

asp:LinkButton>

</td>

<td style="text-align: right;">

<%# FormatPrice(CType(Container.DataItem, eDelivery).Price)%>

</td>

</tr>

</ItemTemplate>

<SelectedItemTemplate>

<tr>

<td>x</td>

<td style="text-align: left;">

<asp:LinkButton ID="lbnDeliveryType2Select" runat="server"

><%# eGlobalization.GetGlobalResourceObject("Localization", "DeliveryType_" & CType(Container.DataItem, eDelivery).ID).ToString%></

asp:LinkButton>

</td>

<td style="text-align: right;">

<%# FormatPrice(CType(Container.DataItem, eDelivery).Price)%>

</td>

</tr>

</SelectedItemTemplate>

<ItemSeparatorTemplate>

<span style="color: Olive; font-weight: bold;"> :: </span>

</ItemSeparatorTemplate>

</telerik:RadListView>

</table>

</div>

</telerik:RadAjaxPanel>

</form>

</body>

Thanks for your suggestions,

[Solved] Numeric Text Box with Rad Input Manager

Hi,

I have some problem in Text Box with Numeric Rad Input Manager.
When I input value more than 20 digit such as 99999999999999999999, the value that I input is always changed to 100000000000000000. In Rad Input Manager, I set max value to 99999999999999999999.

I added screenshot for help. Pict IMG-15052013-104957-Edit.png is when I input value and Pict IMG-15052013-105006-Edit.png
is after I input value.

I just want the value to show correctly to 99999999999999999999 not to 100000000000000000. Can you help me to check this issue ?

Thanks before.

Pie Chart Label Spacing

I'm having an issue spacing out labels for a pie chart. I've tried playing with label margins and positions with no effect. See attached Img. The problem is when two or more very small slices of the pie are next to each other the labels overlap. How can I organize or space out these labels?

Thanks for any help.

Spline RadChart for ASP.NET is not smooth

Hi Telerik,

I am working on a project that converts telerik WPF Spline RadChart to telerik ASP.NET Spline RadChart.

1. The first issue is my asp.net chart is not smooth linke WPF version. How can I improve it (note that I am almost using WPF code).
- Here is my WPF chart: http://screencast.com/t/Xz1cpqdwQKJE
- And my ASP.NET chart: http://screencast.com/t/sbKenlQS

2. The second question is are there any solutions for me to make the animation like WPF version for ASP.NET version?

Thanks
