Hello,

I have a view with RadGridView and RadDataPager. Grid´s source is PagedSource of data pager. Data pager is bound to IQueryable of items so Data pager manages data reading itself. Paging is working well but I don´t know how to refresh grid if user pressed a button for manual refresh. I have tried to use Grid.Rebind() but it didn' t work. Is there any method I could call to explicitly cause Data pager to reads data from database? And is there any event triggered during it? Because I would like to use busy indicator during the refresh.

Thanks,
Karel Bem

Hi support,

I am adding a AggregateFunction to a gridcolumn with the following code:

bool showFooter = false;
foreach (var col in radGridView.Columns)
{
    if (col.UniqueName == "dauer") // Column with double-values
    {
        col.AggregateFunctions.Add(new SumFunction() { ResultFormatString = strFormat, SourceField = col.UniqueName });
        showFooter = true;
    }
}
radGridView.ShowColumnFooters = showFooter;

Adding a footer should only happens if my table has a column of data-type double named "dauer" otherwise columnfooters should not been shown. After doing this the footer has correctly been show but the first time the sum of the column is displayed when I sort a column of the grid via clicking on a column header.

You can reproduce this behavior in your sample-program "persistence framework / gridview serialization" when you put these lines of code in function "OnLoad" of Example.xaml.cs after calling this.EnsureLoadState() (of course you have to add a new column "dauer" to your dataset)

What do I have to do to show the results of the aggregate-function directly.

Thanks in advance

Hi

I need to give to the user the possibility to build filter not only between a Member and a value (like Column1 = 10) but also between two members (like Column1 >= Column2).

How could I do?

how to get current selected row without select row. only when change combobox item.
how to get current grid row according selected combobox?

I want when I select only last combobox to get last grid row item? Hot to do that?

See attached image for more info.

Hi everyone,

I'm creating RadWindow in separate thread, but when I reopen window after closing it , I'm getting System.Threading.Tasks.TaskCanceledException and don't know why. Here is my code

Hi,

my approach is to make sure that an appointment has a TimeMarker and a Category.

The TimeMarker is set by code - so I want to remove the TimeMarker Combobox from the edit / create dialog.

The Category on the other hand MUST selected in the "create dialog"...
BUT:
a.) The "Clear" Button in the category combobox should be removed
--NO clear - just mandatory select
b.) The category Combobox should be disabled if the appointment is edited (not newly created)

How can this be done? (Pleas no "Code behind event handlers" if possible)

I need to display only show rows Selected = true on initial load. When I click the filter option it should have the checkbox next to true selected. Now the user can unselect true/ select false or clear filter etc.
How can I achieve this? 

Hi,
I'm using Telerik version 2014.2.617.40. The MaskedtextInput control in Masked Input Text Input Demo has an unexpected behavior.
Here is the configuration I have.
  Mask: (empty)
  Text Mode: MaskedText.
  Input Behavior: Replace
  Selection On Focus: SelectAll
  Update Value Event: PropertyChanged.

Replication Steps:

1. Type ABC in text input.
2. Select A. Copy A using Ctrl + C.
3. Select B. Paste using Ctrl + V.

What I expect: ABC becomes AAC.
Actual result: ABA.

Is it a bug? or should I modify the control properties?
Thanks.

Regards,
Gong
