In Java Swing, there is a TreeTable component. Is it possible to implement something similar by integrating RadTreeView and RadGrid?

Metro and ItemTemplateSelector

Hello,

I appologise if this has been asked before, but my search yielded no results.

In my application I have a ListBox which has a basic ItemTemplateSelector. This works perfectly fine without any themes, and with Summer theme, but it no longer works when the Metro theme is applied. The Template Selector does not get fired at all. I have narrowed the issue down to the following line of code in my resource dictionary:

<Style TargetType="{x:Type ListBoxItem}">

<Setter Property="telerik:StyleManager.Theme" Value="Metro"/>

</Style>

If I take the Style out, or change it to Summer theme, everything works fine. The issue seems to lie with the Metro theme, but I can not narrow down the issue any further. I have not posted the Tempate Selector code since it works with other themes, therefore I do not think that is where the issue lies. If you want me to post that code as well, please let me know.

Thank you,

RadDateTimePicker in RadGridView (WPF)

Hi,

I am using RadGridView in WPF application and binding it to a DataTable view. For my RadGridView I have set AutoGenerateColumns as "True" (to get my columns automatically).

Problem: In DataTable object (which I am binding to RadDataGridView) I have one DateTime column. In RadDataGridView it only shows Date calender in the dropdown for picking date, but no time. More over I want to change date format for DateTime column. As AutoGenerateColumns is true, I don't have any control over the columns. Can anyone please show me how to show RadDateTimePicker in RadGridView column when AutoGenerateColumns is True?

My XAML code for RadGridView is as below:

<telerik:RadGridView Grid.Row="1" AutoGenerateColumns="True" ItemsSource="{Binding ManualDataTable}" IsReadOnly="False" CanUserDeleteRows="True" Name="radGridViewManualData" ShowInsertRow="True" />

Any help will be highly appreciated.

Regards,
Moon

Window Resize Problem

Hello Telerik

I have the following problem:

When I use docking and I use a single pane at the buttom Capture1.PNG then maximize the Window, then maximize the buttom pane Capture2.png, then restore down the Window, the pane will stay the same (maximized) size Capture3.png. The buttom pane will make the tabs disappear and if I use AutoHide Option it will exced the Window size Capture4.png.

Insert / delete a node

Hello,

I have 2 questions about RADTreeView for WPF:

1) I need to store a value alongside header in my tree nodes. Every tree node will have the follwoing information:
Name
Record #

However, only Name will be visible in the tree (stored as Header). Record # will not be visible but should be stored for background processing. Other tools typically have a Value property alongside Header (or Text). Does Telerik's TreeView allow for storing other data elements in a node?

2: I have a ContextMenu in my tree. Here is the code for the menu's click event:
        private void TreeContextMenu_ItemClick(object sender, Telerik.Windows.RadRoutedEventArgs e)
        {
            // Get the clicked context menu item
            RadMenuItem menuItem = ((RadRoutedEventArgs)e).OriginalSource as RadMenuItem;
            string header = menuItem.Header as string;
            switch (header)
            {
                case "Add":
                    // code to insert a new node below the highlighted node.
                    break;
                case "Delete":
                    // code to delete the highlighted node in the tree.
                    break;
            }
        }

A) How can I insert a new node below the currently selected node in the tree?
B) How can I delete the currently selected node?

Thanks,
Hamid

GridViewCheckBoxColumn from 2012-Q1 does not work correctly

Hello,

I have an old project containing a GridView with a GridViewCheckBoxColumn binded to a bool type data property. With 2011-Q3 the application works. The checkbox state is set accordingly to the property value.

Yesterday I have installed 2012-Q1 and I have noted that this column does not work anymore. Although the data property has a value of "true", the checkbox is unchecked. If I try to manually check the checkbox, when the cell loses focus the checkbox is automatically unchecked.

Also, when the cell loses focus and the checkbox is checked, in the Output window the following message is recorded:

"A first chance exception of type 'System.ArgumentException' occurred in System.ComponentModel.DataAnnotations.dll"

Perhaps you can take a look into this problem.

Thank you.

Create custom filter to select quantity of matching items

Hi,

I want to create a custom filter to select a quantity of matching items. That is, the user has a list of 1,000 items but wants the first (say) 500 that match. I want to use this to allow the user to allocate work items to team members.

I can see how to filter individual items but can I use a custom filter to filter how many items are displayed?

Thx

Rob
