Hello,

I am implementing a drag drop between a listview and a rad treeview. Everything is fine except that when i drag an item to the treeview, the selected hovered item on the treeview does not show.
Is there any 'out of box' solution for this, or it should be implemented manually by detecting the hovered tree view item and changing its color? if it does require manual coding, do you have some short example for it?

Thanks,

Implement Type Ahead in Grid

Has anyone implemented type-ahead capability in the WPF RadGridView like in a windows grid where you can click on a given cell, start to type and have the grid position the current row to the row that starts with whatever letters have been typed? If so can you share some code?

Custom sorting

When setting e.Cancel = true on the event args of RadGridVoew.Sorting event, the grid nevertheless modifies the SortingState of columns.
Say the column was in Descending. In the event handler I set it to Ascending, and set e.Cancel = true.

I expect the final state to be Ascending, but the grid changes it to None, according to its internal logic.

Using Reflector, I can see that UpdateColumnSortStatesOnSort() is called in GridViewDataControl.Sort(), even if sortingArgs.Cancel == true. I believe that that call should be avoided.

Problem with formatting

Hi,
I would like to display the date in the following format : "dd/MM/yyyy hh:mm:ss" instead of the default "dd/MM/yyyy hh:mm", or in other words, I want to add seconds.
I've tried the following :

CultureInfo cultureInfo = new CultureInfo("es-ES");

DateTimeFormatInfo dateInfo = new DateTimeFormatInfo();

dateInfo.ShortDatePattern = "dd/MM/yyyy hh:mm:ss";

cultureInfo.DateTimeFormat = dateInfo;

RadDateTimePicker newTime = new RadDateTimePicker();

newTime.Culture = cultureInfo;

But I encounter a strange problem. I get the following format : "dd/MM/yyyy hh:mm:ss hh:mm".
What am I doing wrong?

Thank you

RadDatePicker tooltip on validation error from viewmodel

Hi,

I'm trying to set the tooltip on the RadDatePicker when I get a validation error from my viewmodel.

<Trigger Property="Validation.HasError"Value="True">

<Setter Property="FrameworkElement.ToolTip"

Value=

"{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors).CurrentItem, Converter={StaticResource edenValidationErrorToolTipConverter}}"

TargetName="PART_DateTimeInput" />

</Trigger>

No matter what I try, I can't seem to update the tooltip.

Thanks,
Andy

Auto row update on value change

Hello,

I wish to bind the GridView to a sql server datasource and I wish that when I update the table in the database, the GridView will automatically update the rows values. I want to achieve this without reloading the datasouce of the gridview.
Now I get the values from the datasource into a datatable and then set the datatable as the source of the GridView so there is no direct connection between the database and the GridView. Is there a way to give the GridView a "SELECT statement" and it will autocheck for changes?

Thank you
