Unexpected behavior of RadGridView.MinHeight

All,

I have found a bug in the RadGridView control which causes the group area to be larger then expected. To reproduce this bug, just set the MinHeight property of the grid view control to some large number. This even proves true in designer mode.

Combobox column

Hi,

When I set a filter on the GridviewComboboxColumn I see the SelectedValuePath instead of the DisplaymemberPath.
This is not what you would expect.

In your RadComboBox you have an ItemTemplate and a SelectionBoxItemTemplate. I also would like to have this behaviour for the GridViewComboBoxColumn. Is this possible?

Thanks,

Thomas.

Combobox column

Hi.

At the moment I can only show one property in the gridviewcomboboxcolumn; the property name I assign to the displaymemberpath.

What I like to do, is to show a datatemplate where I use a combination of several properties of the itemssource e.g. Firstname and Lastname. Is this possible?

Thanks,

Thomas

Combobox displaymemberpath not showing

Hi,

Since the last update (2009.3.1120.35), some of my radcombobox's are not working anymore:
in the selectionbox the linq to sql entity is shown instead of the DisplayMemberPath property.
The selected item is shown as expected.

    
             <telerik:RadComboBox   
        
                                                      Margin="2,0,0,0"

[Solved] AggregateFunctions Footer not working

RadControls for WPF Q3 2009.

I have an ObservableCollection<T> with a class that implements INotifyPropertyChanged, bound to a RadGridView.

A column on the RadGridView implements a GridViewDataColumn for summing and displaying in a footer.

The Sum, shows up correctly upon running the application, however whenever a cell is edited, the sum does not update to reflect the new figure.
Am I supposed to invoke something to update the column sum?

Additionally, Columns are right aligned. Upon entering a leaving the cell, the data is left aligned. Is this a bug?

[Solved] looping through gridview to gather and save data

Hi,

I have a form that uses the rad gridview control. I have 4 text boxes for a user to key in information about a telephone number. Once they click an add button, I place the information into the rad gridview and clear the 4 text boxes. The user then can enter another telephone number and repeat this process as much as necessary.

The data in the rad gridview is not persisted to the database until the user clicks the save button.

When the user clicks the save button, I want to loop through each row in the rad gridview and gather the information and insert it into the database.

How can I accomplish this task? I was trying to use syntax like this:

For Each item In Me.GridTelephone.Items

// gather the 4 values for the telephone for this item

// and insert it into the database

How can I determine the type of each item as I loop through them. For example:

public class telephone

IsDefault as boolean

Number as string

Country as integer

End Class

dim phone as new Telephone()

For Each item In Me.GridTelephone.Items

// boolean

phone.IsDefault = item ???

// string

phone.Number = item ???

// integer

phone.Country = item ???

How can I perform this task?

Error getting started with WPF RadGridView

I just installed Q3 RadControls for WPF demo with VS2008 Pro on Windows 7. I am attempting to follow along with

http://tv.telerik.com/wpf/radgridview/getting-started-with-radgridview-for-wpf

and am hitting an error immediately. When I drag the RadGradView from the Toolbox onto the Design window, I receive a lengthy error dialog:

'Telerik.Windows.Controls.GridView;;;Component\Themes\GenericOfficeBlack.xaml' value cannot be assigned to property 'Source' of object 'System.Windows.ResourceDictionary'. '/Teleric.Windows.Controls.GridView;component/themes/office/black/GridViewToggleButton.xaml' value cannot be assigned to property 'Source' of object 'System.Windows.ResourceDictionary'.
Object reference not set to an instance of an object. Error at object 'System.Windows.ResourceDictionary' in markup file 'Telerik.Windows.Controls.GridView;;;Component\Themes\GenericOfficeBlack.xaml'. Error at object 'System.Windows.ResourceDictionary'.

(This is a fresh install of VS 2008 Pro ... I haven't tried anything else with this config, and no other Telerik demos are presently installed.)

Any ideas what might be causing this? Did I miss an install step of some kind?

Thanks!
