Hi,

I want to show more days in day view. Rite now I can see only 3 days (I have assigned StartDate and EndDate is readonly !)
Is there any other method/property to show more days?

Thanks,

NodeCheckedChanged with AutoCheckChildNodes

I was wondering if there is a way to disable the NodeCheckedChanged event from being fired for all children nodes when AutoCheckChildNodes is set to true.

The reason why I want to know this is that I store an xml string inside the tag of each node. Every node is a possible record in a database. The xml being stored inside each node contains the information for the current node along with all its children nodes. When the user checks or unchecks a node, I need to give this xml to another component which in turns inserts or removes the proper information to/from the database. I know I could keep raising this event for every node and simply keep the info for the current node in the tag, but this could make for a lot of back and forth between components and the database while this way only one call is being made.

I was thinking of keeping a flag inside the NodeCheckedChanged event and checking this flag before processing like the following:

    
                    private void radTreeView1_NodeCheckedChanged(object sender, RadTreeViewEventArgs e)  
        
                    {  
        
                        if (!m_processing)  
        
                        {  
        
                            m_processing = true;  
        
                            // do work....  
        
                            m_processing = false;  
        
                        }  
        
                    }

but I noticed that the calls weren't nested and that it was actually doing all the code before moving on to the next child/sibling node.

Is there a workaround or another event I could use for this? I want to do the work only once and for the node that was actually checked/unchecked.

RadTextBox Focusable and ReadOnly not working in code

Hello,
I have the two following routines. They are both finding the control and the correct toggle state, however the .Focusable, .ReadOnly and .Focus on the RadTexBox are not changing. .Focusable, .ReadOnly display that they have changed, but .Focus does not.
Why is this?
Thanks.

Private Sub SRSOther_ToggleStateChanged(ByVal sender As System.Object, ByVal args As Telerik.WinControls.UI.StateChangedEventArgs) Handles SRSOther.ToggleStateChanged

Dim txt As RadTextBox = Nothing

Dim ICon As System.Windows.Forms.Control.ControlCollection = PersonTabStrip.SuspectList.Item(CInt(SusNum)).Controls

For Each cont As Control In ICon

If cont.Name.StartsWith("SgrpSResident") Then 'get textbox from group controls

Dim theGrpBox As RadGroupBox = DirectCast(cont, RadGroupBox)

For Each Gctrl As Control In theGrpBox.Controls

If Gctrl.Name.StartsWith("SRSOtherTxt") Then

txt = DirectCast(Gctrl, RadTextBox)

MsgBox(txt.Name)

If args.ToggleState = Telerik.WinControls.Enumerations.ToggleState.On Then

txt.Focusable = True

txt.ReadOnly = False

txt.Focus()

MsgBox(

"Toggle On, focusable=" & txt.Focusable & " readonly=" & txt.ReadOnly & " focused=" & txt.Focused)

ElseIf args.ToggleState = Telerik.WinControls.Enumerations.ToggleState.Off Then

txt.Focusable = False

txt.ReadOnly = True

txt.Text = ""

MsgBox("Toggle Off")

End If

Exit For

End If

Private Sub SCatOther_ToggleStateChanged(ByVal sender As System.Object, ByVal args As Telerik.WinControls.UI.StateChangedEventArgs) Handles SCatOther.ToggleStateChanged

Dim ICon As System.Windows.Forms.Control.ControlCollection = PersonTabStrip.SuspectList.Item(CInt(SusNum)).Controls

For Each cont As Control In ICon

If cont.Name.StartsWith("SCatOtherTxt") Then 'get textbox from group controls

MsgBox(cont.Name & " type=" & cont.GetType.ToString)

Dim txt As RadTextBox = DirectCast(cont, RadTextBox)

If args.ToggleState = Telerik.WinControls.Enumerations.ToggleState.On Then

txt.Focusable = True

txt.ReadOnly = False

txt.Focus()

MsgBox(

"Toggle On")

Else

txt.Focusable = False

txt.ReadOnly = True

txt.Text = ""

End If

Exit For

End If

[Solved] Edit GridView Row

Hi,
I have a little problem. When I add columns into the GridView, I can't seem to be able to edit the rows after. The ReadOnly is at false and the AllowEditRow is at true. I don't understand why I can't edit the GridView rows.

Thank's

GridViewDataColumn col1 = new GridViewDataColumn("ID","ID");
GridViewDataColumn col2 = new GridViewDataColumn("name","name");
col1.DataType = typeof(int);
col2.DataType = typeof(string);
radGridView1.Columns.Add(col1);
radGridView1.Columns.Add(col2);

object[] row = new object [] {1, "John"}

radGridView1.Rows.Add(row);

radGridView1.ReadOnly = false;
radGridView1.MasterGridViewTemplate.AllowEditRow = true;

radComboBox.DataSource and radcomboBox.Items NOT matching

Anybody has come across a situation where the radComboBox.DataSource is not null and different from radComboBox.Items even after going through the regular databinding code for a radcombbox?
I was curious since I have just come across such a case. I am using latest Q3 version of Winforms RadControls.

I have found that the radComboBox.DataSource is not null but a generic List<> with a count of 4 elements and the radComboBox.Items collection is a count of 0 elements.
To me this seems strange and counter-intuitive.

When we are deploying a project which is developed by sing Telerik controls for winforms, is it necessary to install the controls first and then the application?

Can we not just install the project without doing Telerik?

RadDateTimePicker MinDate MaxDate

Hello everybody,

as a feature request it would be nice, if the calendar portion of the DateTimePicker could not show dates outside of MinDate and MaxDate (like the MS DateTimePicker).

At the moment it works more like "MinMonth" and "MaxMonth" - you are able to click a day before MinDate, but it is not used.

Greetings,
Daniel
