Hi again
Here is another issue with RTL
With a Dock and some forms that added as documents to that, in RTL it`s expected to see the right-top location of each forms in QuickNavigator, but instead it`s showing the lef-top location of each document in preview as snapshot.
I couldn`t find any property to set it to show custom region of a document.

what`s the solution
thanks

Self Reference Hierarchy Custom Search

Hi all,

I want to highlight row based on text entered in the textbox. Basically I load data from database and show it on the grid with self reference hierarchy relation. Initially grid is collapsed to first level (I have more than 5 sub levels). How do I do that?

Thanks

radgridview virtual mode

I have been evaluating the Winforms SDK and I am stuck implementing a grid with a large changing dataset that I want to display in real-time. If I implement my own IBinding list and set it to the grid's data source is that advisable or should I use virtual mode. I don't know how to implement virtual mode in terms of database changes being realized by the grid (ie. add, delete, modify, insert records). I can't seem to find any information on this relating to notifying the grid that a row has been inserted, deleted etc. I also want the screen painting to be minimized and the currently selected row not to change while data is being updated (unless of course a delete cause the data view to scroll up)
Thanks

datetimepicker

Hi everyone

I am trying to get today with a simple method from datetimepicker. I am open to suggestions :) My current workaround is to add an event handler for double clicking the datetimepickers and setting their values to today inside the handler. But inorder to deploy this method i had to write a double click event handler to all the datetimepickers in the program. I saw in another datetimepicker control (from another component provider) a small today button located on the middle bottom of the drop down calendar which does the job of taking you quickly to today...

Any suggestions ....

Best regards

GridView: Binding Multiple Selection on a CommandParameter

I need to have a context menu on a gridview whereby the user can select multiple rows on the gridview and right-clicked on it then the user can change the Status of the row via the iCommand.

<telerik:RadGridView Name="rcGridView" Grid.Row="0" Margin="15" ItemsSource="{Binding Users, NotifyOnSourceUpdated=True,

UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" AutoGenerateColumns="False" ClipToBounds="False"

SelectionMode="Extended" VerticalAlignment="Stretch" telerik:StyleManager.Theme="Summer" RowHeight="20"

RowIndicatorVisibility="Collapsed" CanUserInsertRows="False" CanUserDeleteRows="False" HorizontalAlignment="Left"

FontSize="11" ClipboardCopyMode="All" ClipboardPasteMode="AllSelectedCells,Default" SelectionUnit="FullRow" CanUserFreezeColumns="False">

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu>

<telerik:RadContextMenu.Items>

<telerik:RadMenuItem Header="Approve" Command="{Binding UpdateSourceTrigger=Default, NotifyOnSourceUpdated=True,

RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:RadContextMenu}},Path=DataContext.StatChgtoApproveCommand}"

CommandParameter="{Binding ElementName=rcGridView, Path=SelectedItems}" />

<telerik:RadMenuItem Header="Hold" Command="{Binding UpdateSourceTrigger=Default, NotifyOnSourceUpdated=True,

RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:RadContextMenu}},Path=DataContext.StatChgtoHoldCommand}"

CommandParameter="{Binding ElementName=rcGridView, Path=SelectedItems}" />

<telerik:RadMenuItem Header="Reject" Command="{Binding UpdateSourceTrigger=Default, NotifyOnSourceUpdated=True,

                    RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:RadContextMenu}},Path=DataContext.StatChgtoRejectCommand}" 
                    CommandParameter="{Binding ElementName=rcGridView, Path=SelectedItems}" />  
        </

telerik:RadContextMenu.Items>

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="ID" DataMemberBinding="{Binding ID}" />

<telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}"

/>

    <

telerik:GridViewDataColumn Header="Status" DataMemberBinding="{Binding Status}" />

</telerik:RadGridView.Columns

>

</

telerik:RadGridView>

Unfortunately, when the user click on the item context menu the command will trigger an iCommand and CommanParameter is null. The CommandParameter should be the multiple selected rows on the gridview. Is there a way to make this work?

GridViewComboBoxColumn Tag attribute

(C#)
When using a GridViewComboBoxColumn is it possible to set the Tag attribute on the cell item who's value comes from the grid combo box.

So I can call:
gridView1.CurrentRow.Cells["ColumnName"].Tag

I understand this would probably have something to do with the GridViewComboBoxColumn DataSource and what it is passed.

For Example
I have two GridViewComboBoxColumns in my GridView, call them "suppliers" and "products".
These items get populated from a database where each has a GUID and a Name.
I would like the Name to show in the grid combobox item for each column and the GUID to be assigned to the grid combo box item tag (or some other place).
When the user changes the "supplier" in any row, I would like to fetch the list of products from the database by searching for the supplier GUID.
Currently it seems all I can get back is the string name. I can see the gridView1.CurrentRow.Cells["ColumnName"].Tag however it is null

Any help would be appreciated, and if you need more info or something to be clearer please ask.

Thanks In advance
Tom.

Custom Appointment Event Handling And DataBound Resource.Color Code Snippet!

Hello Telerik Members,

I have done "A Lot" of searching the net to figure out the best way to Update my datasource or database without User interaction. I was very surprised when i did not see a "AppointmentCreated" event for RadScheduler .... Not sure why this was never an event.
Anyways, I have spent some time to try to give you guys a little more flexibility in the events that happen at runtime.

Also, was unable to find answers to how to assign each resource a color with a databound Scheduler. I was able to get this working as well. I will provide the code for this while here. Hopefully Telerik admins will see this and make it in the code library or sticky this thread ?

Anyways, here you go:

Custom Event Handling:

Imports System.Collections.Generic

Imports System.ComponentModel

Imports System.Data

Imports System.Drawing

Imports System.Linq

Imports System.Text

Imports Telerik.WinControls.UI

Imports Telerik.WinControls.Data



' EVENT HANDLER FOR APPOINTMENTS COLLECTION CHANGED CALLS FUNCTION 

' Appointments_CollectionChanged()

' CAN ADD THIS TO THE FORM_LOAD EVENT

AddHandler RadScheduler1.Appointments.CollectionChanged,



AddressOf

Appointments_CollectionChanged

'Appointments_CollectionChanged()

Private Function Appointments_CollectionChanged(ByVal sender As Object

ByVal e As NotifyCollectionChangedEventArgs) As String

' WILL PASS A ACTION TO CollectionChangedCompleted()

' DEPENDING ON THE ACTION PERFORMED AT RUNTIME

Select Case e.Action

Case NotifyCollectionChangedAction.Add

CollectionChangedCompleted("Add")

Case NotifyCollectionChangedAction.Batch

CollectionChangedCompleted("Batch")

Case NotifyCollectionChangedAction.ItemChanged

CollectionChangedCompleted("ItemChanged")

Case NotifyCollectionChangedAction.ItemChanging

CollectionChangedCompleted("ItemChanging")

Case NotifyCollectionChangedAction.Move

CollectionChangedCompleted("Move")

Case NotifyCollectionChangedAction.Remove

CollectionChangedCompleted("Remove")

Case NotifyCollectionChangedAction.Replace

CollectionChangedCompleted("Replace")

Case NotifyCollectionChangedAction.Reset

CollectionChangedCompleted("Reset")

End Select

Return String.Empty

End Function

' CollectionChangedCompleted()

' THIS FUNCTION CHECKS TO MAKE SURE THE RadScheduler APPOINTMENTS 

' WHERE UPDATED

Private Function CollectionChangedCompleted(ByVal action As String) As Boolean

If RadScheduler1.Appointments.IsUpdated Then

' FORWARD THE ACTION TO performAction() 

                 ' FOR PROCESSING CUSTOM OPERATIONS

performAction(action)

Return True

Else

Return False

End If

Return False

End Function

' performAction()

Private Function performAction(ByVal action As String) As Boolean

Select Case action

Case "Add"

'DO CUSTOM OPERATIONS

' ie: updating your datasource/database

' WITH OUT THE NEED FOR A "SAVE/UPDATE" BUTTON

' AUTOMATED UPDATING :)

Case "Batch"

'DO CUSTOM OPERATIONS

Case "ItemChanged"

'DO CUSTOM OPERATIONS

Case "ItemChanging"

'DO CUSTOM OPERATIONS

Case "Move"

'DO CUSTOM OPERATIONS

Case "Remove"

'DO CUSTOM OPERATIONS

Case "Replace"

'DO CUSTOM OPERATIONS

Case "Reset"

'DO CUSTOM OPERATIONS

End Select

End Function

And the Resources Color Code:

' CALL TO APPLY COLORS TO RESOURCES!!!!

Private Sub applyResourceColors()

Dim colors() As

Color = {Color.LightPink, Color.LightBlue, Color.LightCyan, Color.LightGreen, Color.LightSalmon, Color.LightYellow, Color.LightCoral}

Dim i As Integer = 0

For Each res As Resource In RadScheduler1.Resources

res.Color = colors(i)

' TO MAKE SURE WE DON'T GO OUT OF RANGE FOR THE COLORS() ARRAY

' IF WE REACH OUR ZERO BASED INDEX COUNT ON COLORS ARRAY WE RESET i TO 0

' ALLOWING IT TO REPEAT THE COLORS

Dim colorsCount As Integer = colors.Count

If Not i = colorsCount Then

i += 1

Else

i = 0

End If

Next

End Sub

[UPDATE] - I have noticed that for whatever reason that resource colors get reset after data updating ... not sure why yet but I have contacted Rob Shoemate on his blog about resource grouping to try and see if there is a better way of doing this! If I get any updates i will edit this post so that all can learn from it!

You can follow this blog for responses from Rob here

Hope this helps some of you!

Will continue to contribute when possible!

Thanks,
Mike
