Hi,

I have a grid where I have set the column to valid on property changed which works fine, The red validation appears when invalid and goes when notvalid.

However, a thin red line box persists around the now valid item. I would like to

1) Either remove this secondary validation altogether
2) Would like to align the validation process of this secondary validation so that it also works on property changed

Thanks

[Solved] How do you specify test data, to display in the design view?

We're working on our first major WPF app. Isn't it possible to have test data that can be displayed in controls, especially RadListBox, RadGridView, etc., that would make it easier to style those controls? And such that, when you're running the app in Visual Studio, then the test data isn't seen. How is that done?

Horrible performance problems when using special slots

I have around 8 slots that I use to display working time. Currently there are 700 people (resources) being displayed that share those 8 slots (ie one slot may have up to 700 resources associated with it). At this point I can hardly scroll the scheduleview back and forth or up or down to view data. I do see the Copy method (on my custom slot code) fire almost constantly even when I'm not doing anything. Can someone help me solve this? When I don't add the slots performance seems good.

Hide group indentation for groups with one items

Hi all,

I am using a grid view in our WPF application, the grid is bound to a data model that has two properties called “Class” and “SubClass” along with few other properties (price, year, etc…). The grid has 2 group descriptors for those properties (Class is the parent group, and SubClass is sub-group). Each group and subgroup has a custom styled footer row that displays an aggregate total of prices.

What we are trying to achieve is that when a sub-group has only one item, it should not be indented, we want to appear in the same level as the parent group. Also, there should be no footer total displayed for that group (since the total is just the same as the item price, no need to show the same figure twice). How can I achieve those 2 behaviors?

I tried to using the GroupFooterRowStyleSelector, and have 2 styles for the group footer, one for Visible and one for Hidden states. And detect if row.Group.ItemCount is 1, then set the GridViewGroupFooterRow visibility to collapsed. But that resulted on the Aggregate function are still being shown.

Any help would be appreciated!

Thanks!

[Solved] 'System.MethodAccessException' occurred in Telerik.Pivot.Core.dll

With Version 2013 Q1 (2013.1.220.40), I created a simple pivot grid with LocalDataSourceProvider (just following the get-start instructions http://www.telerik.com/help/wpf/radpivotgrid-getting-started.html ), however, the grid does not show up. And inside Visual Studio - Output window, the following exception log is shown:

A first chance exception of type 'System.MethodAccessException' occurred in Telerik.Pivot.Core.dll

I have tried the similar codes with version 2012 Q3 and it works. Is it a new bug?

(Note that I'm using .NET 4.0 with Binaries.NoXaml)

Filtering in RadGrid

Hi,
I am using Telerik Rad grid in My application. My requirement is like this.

I have Products View with their status whether Active or Inactive. So in this grid i have two Columns named "Products" and "Status".

Please tell how to do this or plz give any sample code.

Row Not Selected When Using CellTemplate

Sample column:

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=SelLang}">

<telerik:GridViewColumn.CellTemplate>

<DataTemplate>

<ComboBox SelectedValue="{Binding Path=SelLang}"

ItemsSource="{Binding Langs}"

SelectedValuePath="LanguageCode"

DisplayMemberPath="LanguageName" />

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

</telerik:GridViewDataColumn>

Clicking any other column selects the row (we have the indicator turned on to easily see this), however, clicking and selecting items in this combobox doesn't activate the row. Which property or other trick did I miss?

Thanks,
Chris

GridViewDataColumn IsReadOnlyBinding

See documentation

IsReadOnlyBinding="{Binding IsActive}"

If I set it to true as in "read-only" it is actually not read only, but setting it to false makes it read only...

Am I missing something?

edit: actually it's working correctly, but the documentation is misleading.
