Is it possible to use dynamic groups with the RadTileList? My groups will be defined by my data and I need a way to bind this in MVVM.

Can the max column/row number be changed?

At the current max of "4", I cannot create a strip of 6 or more months (for example). Is there a workaround for showing more than 4 columns/rows, or is there some technical issue in doing so?

Thanks - Mitch

"Click here to add new row" not always visible

Hi,

It seems if I use the RadGridView,
the option "click here to add new row" is only visible after I edited the first row.
If i use 'tab' to navigate through the cells i eventually enter a new second row.
But at that moment the option "click here to add new row" is not available anymore.
Is it possible to make that option ALWAYS available and make it not dissapear when i enter a new row by 'tabbing'

thanks,
simon

column widths initially not set correct

hi,
following setup: a radpane with a user control with a grid that has two rows (row 1 is height auto, row 2 is height *), the second row contains a radgridview. the gridview holds four columns gridviewdatacolumn, nothing fancy. i'm assigning an observablecollection to the itemssource in the usercontrol.loaded event handler.

for some reason the column widths are not set when starting the software. instead they are as it looks like set to the minimum width. it worked before and i can't remember doing anything to this part of the application.

i have to resize the pane or a column a bit or re-assign the observablecollection to the itemssource and then the correct widths are applied. tried with ColumnWidth="*" and with Width="*" on the GridViewDataColumn entries. also setting AutoGenerateColumns to true shows the same result. setting ColumnWidth="Auto" at least shows the full content for each row but looks ugly because it leaves too much whitespace.

i also replaced the whole usercontrol with a backup i made yesterday but same result. works in the backup, not in the current version. replaced also the other controls with old code and it's still not working.

any clue what could cause this behaviour or at least how i can force the gridview to recalculate the column sizes once the control is displayed?

<telerik:RadGridView Grid.Row="1" ColumnWidth="*" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" ShowGroupPanel="False" AutoGenerateColumns="False" CanUserInsertRows="False" CanUserDeleteRows="False" CanUserReorderColumns="False" ShowColumnHeaders="True" CanUserSortColumns="False" RowIndicatorVisibility="Collapsed">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Title, Mode=OneWay}" IsReadOnly="True" Header="Chord" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding DisplayNotes, Mode=OneWay}" IsReadOnly="True" Header="Notes" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding NumNotes, Mode=OneWay}" IsReadOnly="True" Header="Notes"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding PlayKey, Mode=OneWay}" IsReadOnly="True" Header="Play"/>

Select a row in a radGridView & RadDataPager

Hi!

I've actually a radGridView and a RadDataPager.

The source of the RadDataPager.Source is bound to the radGridView.items.

It was working fine, but I found a problem: Sometimes I have to switch between tabs and select a specified object.

I'm using the RadGridView.SelectedItem =TheNewItem.

But if the new item is on another page, it just doesn't select anything. So how can I do that?

thank you!

How to get the different typenames with custom filter

If I have a cell with string values
"value1" "value2" "value3"

In my custom filter, how do I get these values?

I have made this custom one, but I have hard coded the values

CustomItems = new ObservableCollection<CheckBoxCustomFilterType>

{

new CheckBoxCustomFilterType { Checked = false, Text = "5016" },

new CheckBoxCustomFilterType { Checked = true, Text = "25835" }

};

I need to get them instead and create a list, how would I retrieve those values? I cant seem to find an example, the date one is not applicably here

Listbox and tabfocus of child controls

Hi all,

I updated to the latest version of Telerik's UI for WPF, from version 2013.1.403.40 to 2014.3.1305.40.

In our application we have RadListbox which is bound to a list of items. The datatemplate used holds 2 usercontrols and a button.
The usercontrol in itself has a numericupdown and maskedtextbox. So when all items are rendered there are five controls per listbox item/line.

Now in the past when the user selected one of the controls inside the datatemplate and then tabbed away, all controls in all the items would be cycled over, this is how the user wants to use it. Now with the new version this behavior is not present anymore, when the user selects for example the first maskedtextbox of the first item and tabs, the focus is moved to other fields outside of the listbox and when cycling further, the listbox its items (controls inside it) are never tabbed over again... When I just change the version of the Telerik dll's back to the old ones, I get the behaviour expected.

I've setup a small POC showing that this happens with the RadListBox but not with an ItemsControl.

Any help is appreciated, thnx in advance!

See http://1drv.ms/141ezct for the files.
