I'm having an issue with the numeric input control settings in the input manager. I have a grid that is using ajax for its commands. When one of those commands is executed, the numeric inputs lose their focus. This would potentially not be a big problem, except that their values are lost when the user put focus on the numeric input.

You can actually see this happening in your demo here
http://demos.telerik.com/aspnet-ajax/input/examples/radinputmanager/databinding/defaultcs.aspx

To reproduce, just click on one of the commands in the DateInputSetting grid. For instance, if you click the cancel button on the row that is in edit mode, you will notice the editable numeric box in the NumericTextBoxSetting loses it's formatting. Then all you have to do is click inside that box to see that it disappears when it gets focus.

Is there any way that this could be worked around easily? I have quite a few controls on my form that are using the NumericTextBoxSetting functionality.

Hi Daniel,

In order to achieve the desired functionality please set the InitializeOnClient property to true on every RadInputManager's setting:

<telerik:RadInputManager ID="RadInputManager1" runat="server">

<telerik:NumericTextBoxSetting Type="Currency" EmptyMessage="Freight" InitializeOnClient="true" Culture="English (United States)">

<TargetControls>

<telerik:TargetInput ControlID="RadGrid2" />

</TargetControls>

</telerik:NumericTextBoxSetting>

...

Additionally I am sending you a simple example which illustrates the desired functionality.

I hope this helps.

Hello Daniel,

It is hard to say what is causing the described issue without seeing some code. Could you please send us a simple runnable application demonstrating the problem. You could open a formal support ticket from your Telerik account and attach a ZIP file there. In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.

Best wishes,

I'm also having this same issue.

Basic Master Page contains another Content Page.
Content Page contains a RadGrid with Template Edit Form.
When the RadGrid is registered with the RadAjaxManagerProxy, all styles are lost from the RadInputManager.

I tried the suggestion made above.

Hello Alex,

Placing the RadInputManager into the FormTemplate and registering it via ajax is not suggested, because it is too late for the RadInputManager manager to initialize properly.
To achieve the desired functionality, please check out the following online example which demonstrates how to use the RadInputManager control:
http://demos.telerik.com/aspnet-ajax/input/examples/radinputmanager/dynamicinputfiltersettings/defaultcs.aspx?product=grid

I hope this helps.
