HI,

Is there a way to keep either ends of the itemsource (first and last item) as top item in the caouselpanel whenever I reached the first/last item when scrolling..

Thanks,
Jog

Hello,

I am using CellTemplateSelector to change the color of a cell depending on its value.  I found sample code on how to do this and it works well for GridViewDataColumn but I can't get it to work with GridViewExpressionColumn

 
I'm using the following and it works:

<telerik:GridViewDataColumn DataMemberBinding= "{Binding TotalAdjRateNew}" TextAlignment="Right" Width="100" DataFormatString="{} {0:#%}" IsReadOnly="True">

    <telerik:GridViewDataColumn.Header>

        <TextBlock Text="New Total Adj %" TextWrapping="NoWrap" TextAlignment="Center" />

    </telerik:GridViewDataColumn.Header>

    <telerik:GridViewDataColumn.CellTemplateSelector>

        <telerik:ConditionalDataTemplateSelector>

            <telerik:DataTemplateRule Condition="TotalAdjRateNew &lt; 0">

                <DataTemplate>

                    <TextBlock Text="{Binding TotalAdjRateNew, StringFormat=p0}" 
                        HorizontalAlignment="Right" Foreground="Red"/>

                </DataTemplate>

            </telerik:DataTemplateRule>
        </telerik:ConditionalDataTemplateSelector>

    </telerik:GridViewDataColumn.CellTemplateSelector>

</telerik:GridViewDataColumn>

 

However when I use the code below with a GridViewExpressionColumn  the value is not displaying.  I am not sure what the binding should be inside the DataTemplateRule.

 

<telerik:GridViewExpressionColumn UniqueName="TotalAdjPCT" TextAlignment="Right" Width="100" 
    DataFormatString="{} {0:#%}" Expression="MAN_ADJ_PCT + MOD_ADJ_PCT" IsReadOnly="True">

     <telerik:GridViewExpressionColumn.Header>

        <TextBlock Text="Total Adj %" TextWrapping="NoWrap" TextAlignment="Center" />

    </telerik:GridViewExpressionColumn.Header>

    <telerik:GridViewExpressionColumn.CellTemplateSelector>

        <telerik:ConditionalDataTemplateSelector>

            <telerik:DataTemplateRule Condition="MAN_ADJ_PCT + MOD_ADJ_PCT &lt; 0">

                <DataTemplate>

                    <TextBlock Text="{Binding TotalAdjPCT, StringFormat=p0}" HorizontalAlignment="Right" 
                        Foreground="Red"/>

                </DataTemplate>

            </telerik:DataTemplateRule>

        </telerik:ConditionalDataTemplateSelector>

    </telerik:GridViewExpressionColumn.CellTemplateSelector>

</telerik:GridViewExpressionColumn>

 

Hi everybody!

I want to provide the possibility to select multiple rows, columns and cells like in Excel. That means I need a combination of row and cell selection. Are there any demos are examples how to achieve this?

If I have to implement it myself, an event that is fired when a row or column header cell is clicked would be helpful. Does it exist?

Thanks

Uli

We use several radGridViews in our project and have often included an export button to push the content of the grids to Excel. Our users love the feature.

Recently we discovered a problem when you have a combobox column.  It seems to be trying to convert the display string to the type of the column during the export.  It's difficult to explain so I have prepared a small demo of the problem:

https://www.dropbox.com/s/4zkr5ofgmyfbgtt/radGridViewErrorTest.zip

if you try to export the data it will throw an error saying that the 'String must be exactly one character long'.  For combo boxes that use an integer as the selected value instead of a char (like this example does) the message will ready 'Input string not in correct format'.

Is there a better way to do combo box columns or the export so that this error can be avoided?

Hi
RadPaneGroup.Items.Refresh();

when I use this code in my wpf project all of RadDocumentPane is closed.
whats the basic concept of using RadPaneGroup and RadDocumentPane?

I'm trying to build a page using the DataForm ICollectionVew Synchronization demo as an example - having a GridView and a DataForm bound to the same CollectionView.

My underlying data is an ObservableCollection of my own record objects, which are instances of a class that implements INotifyPropertyChanged and IEditableObject. This collection is populated from a database.

In my VIewModel, I construct a QueryableCollectionView from the ObservableCollection, and I bind both the GridView and the DataForm to this.  Everything seems to work fine, as I navigate through the records, both on the form and in the grid.  Changing the selected record in the form changes the selected record in the grid, and vice versa.

If I edit a record in the form, the changes appear immediately in the grid, and if I hit cancel in the form, they immediately revert to what they were, in the grid.  (Which indicates that the ICollectionView.EditCancel is working right).

I have a CollectionChanged handler listening for changes in the QueryableCollectionView.  When I click on Delete, it sees a NotifyCollectionChangedAction.Remove, and deletes the record from the database.  And this seems to be working fine.

When I click "Add", I see a new row in the GridView, blank fields in the DataForm, and the CollectionChanged handler sees a NotifyCollectionChangedAction.Add, and is passed an empty instance of the record.  All it does then is populate the fields in the record that aren't visible in the GridView or the DataForm.  Later, when the user hit's the "OK" button on the DataForm, the ICollectionView.EditEnd method on the record is called - which does an insert or an update to put the record into the database.

And here's where things go wrong.  The new row in the GridView stays highlighted, like the grid thinks it's still being edited.  And while if I navigate to next and previous records in the DataForm, I see the selected row in the grid changing, if I change the selected row in the grid, I do not see the DataForm updated with the newly-selected record.

Something is not quite right, and I'm at a loss as to where to look.

Any ideas?

Solved, was using wrong property.

Hi,

Event though I have set the WeekGroupHeaderStringFormat property to {}{0:dddd(MM/dd/yy)} it does not appear to affect the header which remains as i.e. 01 Monday. I just wish to have the names of the days displayed as Monday to Sunday without date numbers but seem to be failing, although changing firstDayOfWeek does seem to have an effect. Can anyone help?

I am after a view, like weekview. However only shows every Friday. 

so it may show every friday, for 7 fridays .

I have no idea where to start. 

Hi ,

i have deleted a value in radgridview cell and moved to another cell still the value is showing in old cell. can you please tell me what i need to do to resolve this?

i am using this control for WPF applications.

Hi All,

I am adding the new Row in RowEditEnded Event. When the RowEditEnded is called it Creates two empty Rows. Also when i press Shift+Tab to move focus to previous cell's and focus tries to move previous row it again calls the roweditended and creates the Two Empty Rows. Expected behavior is it should change the focus to previous row.

Also one more thing when i load the GridView it should be with one Empty Row.

Any workaround for this 2 issues.


Thanks and Regards,
Sakthi
