It is painfully clear that Microsoft is dumping WPF into the "Maintenance Only" bin (in favor of Metro).

Is Telerik going to follow suit?  I realize that some of your resources have to be devoted to the new Metro stuff.  But Metro is not a good fit for may Enterprise scenarios.

I am about to start a brand new, very large, enterprise level app with WPF.  Because of this, I would like to know how long Telerik will be giving WPF "First Class" level resources.

Is Telerik able to commit to a time line of how long they will continue to actively and aggressively develop new features and products for WPF developers? 

If you go into windows and and set your display size to 125%, the grid object does not adjust the scrollbar to account for the larger items. This prevents you from scrolling to items that are at the bottom of the list.

(turns out we're using treelistview, not grid view...)

The radgridview has an event for MouseDoubleClick, but is there a way you can catch a single click?
I need to hook on to the "click event" when the selected row in the grid is clicked(once)

When using the If function we were unable to have a results of differing types.  For example
IF(Expression, FieldOfTypeDecimal, 0) will not work

The ExpressionEditor does not understand numeric constants
IF(Expression, FieldOfTypeDecimal, 0M) will not work.

Is there a way to work around this?

I'm attempting to upgrade my project to Q1 2012.  In my project, I want to select the row in the grid when the row details visiblity is changed.  I accomplished this with the following code
 

 

 

private void grdCustomer_RowDetailsVisibilityChanged(object sender, GridViewRowDetailsEventArgs e)

 

{

e.Row.CommitEdit();

e.Row.IsSelected =

 

true;

 

}

This works with Q1 2011, but with Q1 2012, I get the following error

"'NavigatorIndicatorBackground' name cannot be found in the name scope of 'System.Windows.Controls.Border'."

Is there something I need to change to make this work with Q1 2012, or is there a bug?  At this point, I will have to stay with Q1 2011 unless I can make this work with 2012.

Hi.

I try to create a custom aggregate function.

I get this exception.
"No generic method 'SimCandidateCount' on type 'GenerateFieldEmulator.SimCandidateCounter' is compatible with the supplied type arguments and arguments. No type arguments should be provided if the method is non-generic."

Can you either spot what is wrong or tell me how to find out what the failing overload resolution information is?

xaml:

 

 

 

<telerik:GridViewColumn.AggregateFunctions>

 

 

 

 

<local:SimCount SourceField="SimPossible" SourceFieldType="{x:Type System:Boolean}" Caption="Candidate Modules : " />

 

 

 

 

</telerik:GridViewColumn.AggregateFunctions>


The SimCount class is here.

 

public

 

 

class SimCount : Telerik.Windows.Data.EnumerableSelectorAggregateFunction

 

 

 

 

 

{

 

 

    protected override string AggregateMethodName

 

    {

 

 

        get { return "SimCandidateCount"; }

 

    }

 

 

    protected override Type ExtensionMethodsType

 

    {

 

 

        get

 

 

 

 

 

        {

 

 

            return typeof(SimCandidateCounter);

 

        }

    }

 

}

 

 

public static class SimCandidateCounter

 

 

 

 

 

{

 

 

    public static int SimCandidateCount<TSource>(IEnumerable<TSource> source,Func<TSource,bool> selector )

 

    {

 

 

        return source.Select(selector).Count(b => b);

 

    }

}

Hello everyone

I have a RadGridView whose DataLoadMode is set to Asynchronous, and I'm experiencing some trouble with sorting.

In my case the grid is filled with approx 14,000 elements, that can be represented by trips made by clients. Each client has a number, and has made several trips. The columns are, among others, the client number, and the destination of the trip.

Here are the steps that reproduce my problem :
1. I first select only one client number in the standard filtering from the client number column. The display is refreshed and only the trips of the selected client are displayed (~ 4-5 elements)
2. Now I click on header of destination column, normally causing the alphabetical sorting with respect to destination. But instead of this behaviour, the grid refreshes and no elements are shown.

I have put some breakpoints, and found out that the display is not in cause, as the grid.Items is simply set with an emply collection when I click on the column header.

The surprising thing is that it always worked correctly before, when I was using synchronous data load mode.

Am I the only one experiencing trouble with this feature ?

Thank's in advance for your time

Kind regards,
Olivier

Hi,

I am creating a booking system and need to disable certain dates in the RadDatePicker if the products are not available on that day.
Is this possible with a RadDateTimePicker? I have read all the documentation and and the selectable range looks like it would work but I need disable multiple single days.


Thanks

Hi,

It seems a bug in the GridViewBoundColumnBase.CanFilter() of the 2012.1 release.

I'm binding my grid to a collection of ExpandoObjects, and I found that when I set grid.IsFilteringAllowed to true, the FilteringDropDown controls shows up on column headers, but they didn't go hidden when I set grid.IsFilteringAllowed to false.

By looking at the disassembled code, I found that GridViewBoundColumnBase.CanFilter() has been changed to this:

        public override bool CanFilter()
         {
             return (base.CanFilter() || (this.IsBoundToDynamicType() && (this.EffectiveFilteringType != null)));
         }

In my case base.CanFilter() is false and this.IsBoundToDynamicType() && (this.EffectiveFilteringType != null)) is always true, which means there's no way for me to simply toggle grid.IsFilteringAllowed to show/hide the filter control.
