Hi everyone，

I want to set the  color of the selected RadTabItem . I setted MaterialAssist.FocusBrush ,but it was not obvious. Can I set  the selected color like radiobutton in RadTabItem ,cover all the area?

Thank you!

hi Team,

I need to add a radpath button to the RadGridView's searchpanel .

RadGridView  doesnt has a particular style  property  for searchpanel, like it has for groups (i.e. GroupPaneItemStyle).

So I extracted the style, and to the control template added the radpath button.

But then this style is used globally in my application.  So this  button comes at  all  the places where the  RadGridView is used.

Now  I want to  add a attachproperty to the   radGridViewSearchPanel ,  which  can  be accessed from my different views and I should be able to control the  visibility  of my radpathbutton.

So I want something like this -

 <telerik:RadGridView
    Name="DeviceConnectionsGridView"
    ShowSearchPanel="True" 
    SearchPanelCloseButtonVisibility="Hidden"
My_AttachedProperty_For_SearchPanelsRadPathButtonVisbility =  "Visible"
/>

Here's what I performed -

I added an attached,  to  the GridViewSearchPanel class, but this property is only accessible where the GridViewSearchPanel is used.

In my case  ggridViewsearchpanel is  not  used directly but  coming from the  RadGridView, so this attach  property  is  not coming for R
adGridView.

So  plz  tell  me, how  can we  achieve  this ?

How can I add my own button as I marked in the picture?

In Gridview collection, once collection is loaded from data source, we evaluate some conditions, that depends on previous records. Such that if previous record and current record has same Owner Id, then hide signature of current record i.e. IsVisible=false; else make it visible. 

e.g.

index 0:     {OwnerId = 123, IsVisible=True}        // Index 0 is always true

index 1:      {OnwerId = 123, IsVisible = false}    // Index 1 Owner Id == Index 0 Owner Id

index 2:     {OwnerId = 456, IsVisible = true}   // index 2 Owner id != index 1 Owner Id

Index 3:     {OwnerId = 567,  IsVisible = true}

Index 4:   {OwnerId = 567, IsVisible =  false}

Before using VirtualQueryableCollectionView, we can easily iterate collection, but as VirtualQueryableCollectionView is loading items on demand, therefore I need to iterate collection on each load.

If I implement such evaluation in ItemsLoading or ItemsLoaded event, It hurts performance. I want suitable place, where itemsLoading is completed, new collection is rendered in gridview and then I can iterate collection.

Is it possible in VirtualQueryableCollectionView. Is it right way to handle such situation. What can be alternative.

Hi Telerikers,

I would like to reduce the number of makers (basically I would display the makers only in the first, last, max and min values) . However, I don't want to simplify the data because that make change on the shape of line.

Would you please help me a solution to modify the display of makers? 

Many thanks for your help

I have a RadComboBox with a list of items in ItemsSource
My SelectedValue is an int property and I display the corresponding string property from the list.

If the SelectedValue property is not in the list then it does not display anything.

Is there a way to set the display text in the RadComboBox when the SelectedValue is not in the ItemsSource list?

I've tried setting Text but it didn't work.

(note the RadComboBox is not editable)

I use RadScheduleView for appointments for users who need to get them on mobile.

I mean I have a desktop app where someone manages the schedule and appointments and he sends them to the server

and saves them in DB.

The server should then send the appointments to the user accordingly.

The question is what should I do if I have an appointment created let's say two years ago and it recurrence which means

it still comes back every week and the server needs to find it to send to the user.

How can this be dealt with?

Because in normal cases the server can do a search for appointments created on dates from X to Y,

but in this situation, it will not see this appointment.

Would appreciate help.

Hello,

I have this GridViewDataColumn "Real Quantity" which has a CellTemplate with a RadMaskedNumericInput,. If we put in a value (e.g. 0.02) and save it, it will fire an AggregateFunction which calculates the Qty remaining to 4.76. I tried to make this happen in real time while typing in a value without having to save and reload the page to show the calculation .

Does anyone have any idea how i could do this?

Regards,

Matthias

Hi Telerik team,

I have a RadCartesianChart which i hided the values labels (see attached picture-1 ). I would to have a behavior like that: when mouse hover on a legend item (Cash, Time deposit, Shares, Bond... ) in the bottom of chart, the chart will display the corresponding line AND THE VALUES LABELS on the line (like you can see picture-2).

Would you please help to realize that?

Many thanks 

I have a RadGridView with a frozen first column, so that the user can see that value even when the grid is scrolled horizontally.

I would like to print the grid.  If the grid is wide enough that it extends to multiple pages, I would like that first column repeated on the additional pages.

I am using ExportToWorkbook and then RadSpreadsheet.Print to print.  I have tried using worksheet.ViewState.FreezePanes on the first column.  That doesn't cause the column to repeat when printed.  

Is there a way to cause the first column to be repeated when the printout is wider than a single page?
