Hello everybody

I have a problem with radgridview row resizing when this propterty is enabled.
I don't know how to transfer the change of RowHeight  to controls inside a DataTemplate like this

                <telerik:GridViewDataColumn DataMemberBinding="{Binding text1}" Header="Data Template" >
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <TextBox Text="some letter" VerticalContentAlignment="Stretch" Margin="0" />
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                </telerik:GridViewDataColumn>

When I resizing the row the height of textBox is always the same, centered in the row.
This behavior is visible in the image annex to this Thread.
I would like the height of the TextBox to follow the row height of the RadGridView (stretched vertically)

thanks in advance

I have a project, which I'm updating to use the Telerik controls. As part of this, I have changed a standard ListView into a Telerik GridView. However, I have come across a problem.

The gridview consists of a number of row bound to an observable list, each of which has a RowDetails template, showing another list of information in a ListBox. Double clicking on the items in the list box performs an action, based on the selected row in the gridview (using a binding on the SelectedItem).

Previously, when selecting an item in the rowdetails, the listview grid would also select the parent row in the grid, thereby allowing our code to work. However, with the telerik gridview, selecting an item in the listbox DOES NOT select the parent row. As such, the selecteditem is either wrong or null, so the code fails.

Is there a way to make the selected grid row reflect the currently focused listbox in the details?

We would like to add a Status column to our grid that has a colored box for each of the different boolean flags that have been set on a row.  

The table has AutoGenerateColunns set to true right now so all of the fields show up as check boxes.  We want to merge them all into one column with a title of Status.  We would love if we could duplicate this:



Any guidance on what control(s) to use?  

When the expander is expanded, it does not cover up the controls underneath.  Both the content of the expander and the controls "covered" by the expansion are visible. 

How can I "hide" controls on the form when the expander is expanded?  Is there a property on the expander that I'm not seeing?

I'm facing problems with TileList, I want to allow the user to change the tile size at runtime. When you change the tile size (tiletype) pragmatically, in a random manner the tile size and UI got corrupted.

To reproduce the problem:

XAML CODE:



VB Code:


Run the application:

1- Click on "All SMALL" button to set all tile to single
2- Try to reorder some tiles
3- Click on "All Quadruple"

You may notice that some tiles size looks like single while it is Quadruple. (see the attached images)

Also another problem, I'm not able to figure out how the tile reorder is working, sometime I drag drop a tile it does not move, sometime it works! if I drag over another tile sometimes work some time not, Very inconsistent not similar to the windows 8 tiles, I don't think I can use it with production environment. Please advise.

Hello,
I'm creating datagrid with dynamically created columns. The ViewModel looks like:

And I create columns this way:


I had some problems - sorting (fixed by custom ICollectionView link) but now I have issue with filtering. When i try to filter, grid becomes empty. And also I cannot see list with checkboxes to select desired values (like for normal column bound to string property).

Is there anything I can do with that? ICollectionView  has filter property, but it's not used in Telerik Datagrid (?).

Hello,

I have no explicit style on my DataPager

<telerik:RadDataPager x:Name="radDataPager" Source="{Binding Items, ElementName=customersBox}" />

but the previous and next buttons are empty, why? They are clickable but I need a hint what happens when the button is clicked.

Regards,
Ylva

Hi,

When a RadGridView's ItemSource is bound to a VirtualQueryableCollectionView, user navigation in the RadGridView causes the VirtualQueryableCollectionView to accumulate loaded objects.  From a memory management perspective we would like to be able to unload objects from the VirtualQueryableCollectionView - for example, we may want to unload anything outside the range of current row index +- 500 on an ongoing basis to limit our memory footprint.

The use case for this is any application where the user operates iteratively on a large set of large objects.  When moving down the list in the RadGridView, processed rows are never viewed again yet their associated objects remain in memory unavailable to the Garbage Collector. 

Unloading these objects from the collection should result in the objects being re-fetched by the ItemsLoading event handler if they are required for subsequent display in the RadGridView.

There appears to be no mechanism for identifying which items should and should not be unloaded.  ResetAll does as its name implies  - unloads all items - which is far too heavy handed for our desired behavior.

Setting an item to null (via RemoveAt(index), Insert(index, null) produces undesired behavior - the item is not refetched when its row is redisplayed, RadGridview displays an "=" in the row, and the item cannot be removed from the VirtualQueryableCollectionView (RemoveAt fails silently). 

QUESTION:  Is there a mechanism by which ranges of items can be reset in (unloaded from) a VirtualQueryableCollectionView?

I've accomplished this using reflection to remove items from the the private "loadedIndexes" collection but obviously would NOTdo that in production code.

Thanks,
