prevent drag and drop within parent node

hi telerik team,
i am using radtreeview which is very useful for me in my current project, but, i need a help to accomplish it successfully ....
i have populated the tree view from a dataset. there will be more number of parent nodes and within each parent node, more than one child nodes will be there. Now i have to restrict the user to drag and drop the child nodes within the parent node itself. (Meaning : User should not interchange a child node from one parent node to another parent node. they should interchange or arrange a child node within its parent node itself). i dont have any idea about doing this in the tree view, so pls help me as soon as possible.

Thanks,
Guna

GridView and Enum

Hi

I've one question about the radGridView:

I want to bind a list of object (where I have an Enum property called Status) to my radGridView.

the problem is when I try to update a row I have an exception when I update the property Status, and I have the same problem when I try to set the related filter.

One solution was to create a custom Column and a Custom filter and then my grid work fine, and then I have to define the binding by myself.

My question is : when I set the grid DataSource by code and without define the mapping (cells definitions) It is possible to use automatically this custom column (and filter) when the column source is an Enum?

Then, if I have to class (ClassA, ClassB) with an Enum Property and if I try to set the Grid DataSource with a List of ClassA or ClassB, my grid detect my Enum property and use the custom column.

Thanks for your response

[Solved] How to upgrade to the latest Q1-2011 ?

Hi...

Glad to hear that Q1-2011 is released. I think, there is an updated control that I was much awaiting for it to be released. :-)

One question. After we download the latest version of WinForms controls, how would we make changes to the apps that already uses an old version of these controls ?

Thanks

[Solved] Making a control "ugly"?

Hi there.

I got a quite unusual task. I have an old winForm 2.0 Application which has no theme at all. It looks a bit like XP without luna. No designs etc.

Now I need a telerik radgrid but do NOT want any theme there. It should be as "ugly" as default

Any chance to achieve this?

Export To CSV - Decimal places

Hi,
I am trying to set the decimal places in the export to be a customizable setting. I am using the following lines of code

col.ExcelExportType =

DisplayFormatType.Currency

col.ExcelExportFormatString = GetDecimalFormat()

WHere the GetDecimalFormat would return "{0:#.##} for 2 decimal places.

But this snipet does not work. It renders on the csv witht the same number of decimal places as in the data. Are there similar properties for csv as there are for excel?

Thanks
Deepak

Cant add time in GridDateTimeColumn?

Hi guys,

this may sound stupid but how do you add edit the time in a GridDateTimeColumn in the grid view? Everytime i click on the column, the text box shows only the date component e.g.[ Thursday, 1 April 2011 ] which is fine but I would also like to be able to edit the time in the column... clicking on the dropdownbutton in the editor calls up the calendar but that only allows me to change the dates.

Please Advise.

Thanks

[Solved] gridviewcolumngroup headers wrapping text

The gridviewcolumngroupheaders are wrapping texts. While this is ideal, it does not expose a property or method to show tool or screen tips with the full text on mouse over. In the attached image, (Q1) - Spontaneous Awareness - is actually (Q1) - Spontaneous Awareness - First Mention

Thanks
