Hi,
I'm using the Outlook Template from Telerik.
What I've done is that I've swapped the current grid with my own item source which list the categories the 1. grid.
What I want to do is upon selecting a row, I want upon choosing a row from the 1.grid to send categoryID parameter to viewmodel, and viewmodel is going to run the sample function which retrieves the data from the database.
My function is retrieving the data just fine. I just need to find out how to make selected row in grid 1, call on this retrieve data function and update the gridview 2 with new items. If I decide to choose another row in grid 1, it would call on the retrieve data function again with new categoryID as parameter
How can I achieve this?
Hello
I am in vb.net with wpf, I have an existing radgridview with custom validationDiffProperty. I am using telerik v 2017.3.1018.45
My goal is to add a radgriview row with radcombox (see attach image). I know how to add a radcombobox column in a radgridview, but I don't know how to add a "radcombobox row" in a radgriview.
Could you please help me ?
Regards
Jean-Christophe


I have a timebar used to selecting time range. However sometimes when the interval is short and located far to the right, the text showing the selected time is cut off, like this: https://i.gyazo.com/179cc9d932da3bcfa08fe38558cbb0ca.png
How can I prevent this? For example make the label right aligned instead of left aligned if it's too far to the right.


I'm needing the datetimepicker to allow the user to select an option for each second over the day, but when i'm down to just 15 minutes the boxes get too small for being able to see the text.
I've scrolled view documentation and the forum and can't find any solution.

Hi,
I have a grid with 4 columns. On selecting/changing value for 3rd column(i.e.: NewFamily) I want to programmatically set some value for the combobox in 4th column (selected value as well as list)
Here is the xaml:
<telerik:RadGridView Grid.Row="0" x:Name="PartFamilyGrid" AutoGenerateColumns="False"
ColumnWidth="*" MinHeight="150"
RowIndicatorVisibility="Collapsed" SelectionChanged="PartFamilyGrid_SelectionChanged"
>
<telerik1:StyleManager.Theme>
<telerik1:VisualStudio2013Theme/>
</telerik1:StyleManager.Theme>
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Family}" IsReadOnly="True" />
<telerik:GridViewDataColumn DataMemberBinding="{Binding Part}" IsReadOnly="True" />
<telerik:GridViewDataColumn>
<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
<telerik:RadComboBox ItemsSource ="{Binding NewFamily}" SelectionChanged="NewFamilySelected" />
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>
<telerik:GridViewDataColumn.Header>New Family</telerik:GridViewDataColumn.Header>
</telerik:GridViewDataColumn>
<telerik:GridViewDataColumn>
<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
<telerik:RadComboBox ItemsSource ="{Binding NewPart}" SelectionChanged="NewPartSelected" />
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>
<telerik:GridViewDataColumn.Header>New Part</telerik:GridViewDataColumn.Header>
</telerik:GridViewDataColumn>
</telerik:RadGridView.Columns>
</telerik:RadGridView>
Items of this RadGridView are objects of this class
public class PartFamilyGridItem : INotifyPropertyChanged
{
public string Family
{
get; set;
}
public string Part
{
get; set;
}
public List<string> NewFamily
{
get; set;
}
public List<string> NewPart
{
get; set;
}
public event PropertyChangedEventHandler PropertyChanged;
}
In the SelectionChanged event (NewFamilySelected) for the RadComboBox in 3rd column i want to handle this task. But I am not sure how to do it.
Do I need to get the row of the RadComboBox (from 3rd col) for which value is modified, select the RadComboBox from 4th col and finally change the selectedValue?
A similar issue is handled here https://www.telerik.com/forums/change-the-cell-content-at-runtime#MtiwER8x9USdCWTtLyu5_A
but I am not getting how to handle it for combobox
| radGridView.Rows[radGridView.SelectedRow].Cols["Col_Name"].value = |
| MY_NEW_VALUE; |
Hello again!
I'd like to create custom class that is RadDiagramConnection and has its full functionality within RadDiagram , but with some additional data ( implementation of additional interface).
When I am creating it via inheriting from RadDiagramConnection ( as it is recommended in Telerik documentation here: https://docs.telerik.com/devtools/wpf/controls/raddiagram/howto/create-custom-connectioncap ).
But when I add it to my RadDiagram, I see nothing. As I know where my LineObject is I can click on it and see 2 ancor-points, but I can not see RadDiagramConnection itself. Picture is attached.
Would you be so kind to tell me how I can implement this thing?
This is my .cs file
public class LineObject : RadDiagramConnection { }This is my Xaml file:
<telerik:RadDiagram > <telerik:RadDiagramConnection StartPoint="250,250" EndPoint="150,150" SourceCapType="Arrow1Filled" TargetCapType="Arrow1Filled" SourceCapSize="20,20" TargetCapSize="20, 20" StrokeThickness="5" Background="Red" Stroke="Red" /> <imageeditor:LineObject StartPoint="150,250" EndPoint="250,150" SourceCapType="Arrow1Filled" TargetCapType="Arrow1Filled" SourceCapSize="20,20" TargetCapSize="20, 20" StrokeThickness="5" Background="Blue" Stroke="Blue" /></telerik:RadDiagram>
Best regards,
Tatiana
