Disable Aggregates for a single GridNumericColumn

Hi,

I am using the aggregates context menu to allow the user to choose their own aggregate functions, however, 1 particular column should not allow aggregation as each row is potentially showing a value in a different currency.

Is there any way that I can disable aggregates for this column only? There doesn't appear to be any column setting relating to this.

Thanks in advance,
Mike.

Weird problem with System.Web.Extension version

Hi, I'm modifying an old VS project, it uses .net 2.0 and I normally add my telerik RadComboBox and there is no problems...

The thing is that in a different PC, there is an error, the other PC has the same telerik version and the same visual studio version, this is the error:

Assembly 'Telerik.Web.UI, Version=2016.2.607.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' uses 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' which has a higher version than referenced assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

Then I researched and I realized about the project being in the past in .net 2.0 and I guess that for the future all references to old System.Web.Extensions and lower .net should be replaced with newer versions, but the thing is that I don't get why in my PC i don't get the error and in other PCs the error is there even if I add the telerik control in those PCs, i.e., if I go with the project to other PC and add the telerik RadComboBox there, I get the error anyway...

I'ts kind of weird, please any help or at least some explanation.

Thanks in advance.

Cannot fi

Hello,

I have some interesting problem with RadGrid.

My Rad grid has export buttons (CSV, Excel etc).

Clicking them invokes ItemDataBound event handler attached to the RadGrid.

protected void rgManagementSummaryReport_ItemDataBound(object sender, GridItemEventArgs e)

{

if ((e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem) && e.Item.DataItem != null)

{

Button btnPreview = (Button)gdi.FindControl("btnPreview");

}

I have following template column. Initially it had RadButton btnSearch instead of Button btnSearch. It appears that FindControl("btnSearch") would only find asp.net built in Button but not RadButton. I looked at Controls collection of Preview column and saw that it only had my HyperLink and some Literal ones. That's why I had to swith to a regular Button. But our ueb site's pages utilize RadControls everywhere so I would like to be able to return RadButton there and make it find.

Btw regular RadGrid databinding works ok and RadButton is found there as always, so it must be something releated to these Export buttons.

Thanks

<telerik:GridTemplateColumn UniqueName="Preview">

<ItemTemplate>

<%-- <telerik:RadButton ID="btnPreview" runat="server" Visible="false" Text="Preview" OnClick="btnPreview_Click">

<Icon PrimaryIconCssClass="rbConfig"></Icon>

</telerik:RadButton> --%>

<asp:Button OnClick="btnPreview_Click" runat="server" ID="btnPreview" Text="Preview" Visible="false" />

<asp:HyperLink ID="hlReportView" runat="server" Visible="false" Target="_blank">View Report</asp:HyperLink>

</ItemTemplate>

</telerik:GridTemplateColumn>

Default value for Filter Menu when empty

If I have a RadGrid which has a column that can have A, B, C or blank displayed in the column and I enable it to be a filtered column with a check box.

Can I assign a value to value to show up in the popup menu for blanks?

so for example instead of

[ ]

[ ] A

[ ] B

[ ] C

I would see the menu displayed as

[ ] Empty

[ ] A

[ ] B

[ ] C

Bootstrap modals inside a RadWizardStep on an iPad

Hi Telerik!

I have a radWizard I'm using, and one of the wizardSteps has a user control which uses several Bootstrap modals.

Everything works wonderfully on PC, Android, etc - except iPad. When the page is loaded on an iPad, the wizard changes to rendermode="mobile", that all works fine.

However, when I launch any Bootstrap modal whose code is within a wizardStep, the screen is disabled and the content is shown only within the radstep content container (see photo).

Again, this only happens on iPad - works fine on everything else.

My code is structured like this:

Page pseudocode:

<radWizard>

<radStep>

content

</radStep>

<radStep>

<myUserControl>

</myUserControl>

<radStep>

content

</radStep>

<radWizard>

myUserControl pseudocode:

<myUserControl>

<button>Show Bootstrap Modal</button>

<div id='bootstrapModal' class='modal'>

My modal content

</div>

</myUserControl>

iPad iOS version: 10.1

Thank you!

RadTreeView does not respond to click event

I am using radTreeView with server side postback. The tree has 2 levels.

I have implemented scrolling functionality on the treeView so that the tree automatically scrolls to a particular node when the page loads.

So in cases when there are large number of nodes (1000), the page is slow to load and many times the mouse click does not trigger the OnClicked event.

So if the page is refreshed, the tree does not scroll to that particular node.

How can I improve the performance of the radTreeView using server side postbacks only ?

UI Culture changes back after some time

Hello,

I am using RadScheduler in ASP.NET MVC - WebService binding. I am setting culture in OnLoad event, but this setting is reverted to English culture after some time (usually 2-3s). I observed, that it happens after my SchedulerProvider method GetAppointments(RadScheduler owner) is called, but not sure.
Do You have any clue what is wrong with that?I am stuck on this for a while.

Thank You

Here is my sample code:

    
            <script runat="server">

                    RadScheduler1.Culture = CRM.Web.Code.Globalization.GlobalizationManager.CurrentUICulture; 
        
                    // Set first and last day of a week
