[Using 2015 version]

When row is validated and error set, followed by cancel of the edit, the error persists in the tooltip of the row.

I have implemented the fix suggested by Telerik:-

 private void RowEditEndedCommandHandler(GridViewRowEditEndedEventArgs e)
        {
            if(e.EditAction == GridViewEditAction.Cancel)
                e.UserDefinedErrors.Clear();
        }

Although this clears the list structure in code, the tooltips remain in the grid - this solution does NOT work.

I've created a simple project which displays this problem.

I really need to find a solution to how to clear the error from the tooltips following edit cancellation.

Thanks!

Hello,

I want to use custom provider in my project,

the map can be shown right,but the minimap is nothing in the map.

what should I do?

here is the code in my project:

XAML:

<telerik:RadMap x:Name="map"  Center="73.8737, -31.9043" ZoomLevel="7"  MinZoomLevel="3" MiniMapExpanderVisibility="Collapsed">
            <telerik:RadMap.Providers>
                <provider:MapProvider></provider:MapProvider>
            </telerik:RadMap.Providers>
</telerik:RadMap>

MapProvider :

public class MapProvider : TiledProvider
    {
        public MapProvider() : base()
        {
            MapSource mapSource = new MapSource();
            this.MapSources.Add(mapSource.UniqueId, mapSource);
        }
        public override ISpatialReference SpatialReference
        {
            get
            {
                return new MercatorProjection();
            }
        }
    }

MapSource:

public class MapSource : TiledMapSource
    {
        public override void Initialize()
        {
            RaiseIntializeCompleted();
        }

        public MapSource() : base(3, 18, 256, 256)
        {
        }

        protected override Uri GetTile(int tileLevel, int tilePositionX, int tilePositionY)
        {
            int zoomLevel = this.ConvertTileToZoomLevel(tileLevel);

            if (tilePositionY > Math.Pow(2, zoomLevel - 1) - 1)
            {
                return null;
            }

            string url = "http://www.arcgisonline.cn/ArcGIS/rest/services/ChinaOnlineCommunity/MapServer";
            
            StringBuilder builder = new StringBuilder();
            builder.AppendFormat("{0}/tile/{1}/{2}/{3}", new object[] { url, zoomLevel - 1, tilePositionY, tilePositionX });

            return new Uri(builder.ToString());
        }
    }

and here is the result:

Hello,

I am using RadRichTextBox in my project as a reporting tool. I have created a basic structure of application and it seems to be working fine. I am setting MailMergeDataSource to a collection to generate report of more than one selected records. For example If a user selects 10 records, 10 pages will be created in final report. (assuming 1 page per report). User can now edit the generated report (like formatting, refining and so on). Till this point it seems to be achievable. I further want to get all these 10 updated pages of reports separately (with the changes done on the view), I am not sure how to do it.

Following is the line I am using for MailMerge

radRichTextBox.Document = radRichTextBox.MailMerge(); //Start each record on new page.

I am not sure how to get the boundaries of each report. because if I use the API to regenerate each report the changes done on the print preview will be lost.

This is what I am talking about

IDocumentFormatProvider formatProvider = DocumentFormatProvidersManager.GetProviderByExtension(".docx");

for (int i=0;i<number_of_records; i++)

this.radRichTextBox.Document.MailMergeDataSource.MoveToFirst();

var doc = this.radRichTextBox.MailMergeCurrentRecord(); // returns a RadDocument that is the result of substituting the merge fields with the data from the current record.

byte[] binnaryReportData = formatProvider.Export(doc); //but changes will be lost

this.radRichTextBox.Document.MailMergeDataSource.MoveToNext();

}

How can I achieve this?

Hi, I am using Bar chart to display some data. But most often, the bars are too small to be visible in the view. Please see attachment.

Is there something I can set so that even though the Y value is small, bar is still visible in the view?

Thanks,

I am using the RadGridView control in an MVVM (Light) application. I added the following EventToCommandBehaviors to initiate row validation when leaving the selected row:

<telerik:EventBinding EventName="RowValidating" Command="{Binding ValidateCommand}" PassEventArgsToCommand="True"/>

<telerik:EventBinding EventName="RowEditEnded" Command="{Binding SaveCommand}" PassEventArgsToCommand="True"/>

Here's the method and helper method that gets called and works like it should to add the error:

        private void ExecuteValidate(GridViewRowValidatingEventArgs eventArgs)
        {
            var employee = eventArgs.Row.DataContext as Employee;
            if (employee?.RecId == (int)RecEnum.CertainState && employee.OtherRecId == null)
            {
                var validationResult = new GridViewCellValidationResult
                {
                    PropertyName = "ColumnUniqueName",
                    ErrorMessage = "Must enter a OtherRecId when RecId is set to CertainState"
                };
                eventArgs.ValidationResults.Add(validationResult);
            }

            if (eventArgs.ValidationResults.Count > 0)
            {
                eventArgs.IsValid = false;
            }
        }

And finally, following the instructions of removing the UserDefinedErrors, I add the following line in the RowEditEnded event:

            eventArgs.UserDefinedErrors.Clear();

If I fix the error, the row is saved, but the mouseover error message remains even though there are no errors. I followed your directions by adding the eventArgs.UserDefinedErrors.Clear(), but this didn't help.

Does anyone have any workarounds or must this bug be fixed?

Thanks for your help.

I'm working on porting a Silverlight project to WPF, both projects use the telerik controls which has made it surprisingly easy (thank you).

However, I'm now trying to port an upload page that uses the Silverlight RadUpload control to the WPF RadCloudUpload and I'm not sure where to start. The target of the upload is an asp.net website; do you have any examples of wiring up RadCloudUpload to asp.Net using something like the RadUploadHandler target that RadUpload uses? 

Thanks,

Richard

Hello

I have 3 questions.

How can I hide the Timeruler on the top of the Scheduler (RadScheduleView on Timelineview) so only the date remains visible (see attachment)?

When I drag and drop one (or more) appointment else where the selectedappointment goes to any other appoinment except the dropped one. I want  the dragged appointment to remain selected. How can i achieve this?

Is there any way to disable the keyboard combination ctrl + mouse-left-button on (Appointment)Multiselection case? I only want to do it on code behind.

Sincerly

Kasar
