Does anyone know if it Is it possible to hide the expand/collapse button at all?  I am trying to preserve as much horizontal space as possible and also fulfill a requirement that the first level of nodes is always expanded.

I've come across a solution for the ASP.NET AJAX suite but nothing for the WinForms (http://www.telerik.com/community/forums/aspnet-ajax/treeview/drop-expand-collapse-image-from-root-node.aspx#854721)

Thanks,

Hi,

I am developing a windows application.

In that I have a form with a gridview placed on that.

In form I have Update button also.

When user selects one row and click on update ,it has to redirect to another form with the selected data and user can enter details in that and when user click on update data should saved back to database.

How can i acheive this,specifically redirecting to another form with selected records and on click on update button how to save this to database

Please help me,if anyone can post some code snippets then it would be great.

i am new at this so it may be a stupid question !

I have a dataset in VB.NET 2010 , i am getting the dataset using FillBy method , providing one parameter , 
 Try
            Me.daNatalog.FillBy(Me.DsPatients.Patients, txtPatkey.Text)
        Catch ex As System.Exception
            System.Windows.Forms.MessageBox.Show(ex.Message)
  End Try



i want to update the underlying data with any changed data in any of the bound controls. 

I am using one of the control as an example to understand this , its a radTextBox(txtEmail) whose databinding Text property is set to PatientBindingSource - email , DataSource Update mode is OnPropertyChanged 

i add this code to update dataset , this only update first character or give me some error

Private Sub txtEmail_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtEmail.TextChanged

        DsPatients.Tables(0).Rows(0)("e_mail") = txtEmail.Text.ToString
        daNatalog.Update(DsPatients.GetChanges())

    End Sub

This code does not do anything.

Private Sub txtEmail_Validated(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtEmail.Validated
        DsPatients.Tables(0).Rows(0)("e_mail") = txtEmail.Text.ToString
        daNatalog.Update(DsPatients.GetChanges())

    End Sub

Please let me know how would i get this working 

Thanks

Is there a way to create an override of the GridViewSummaryItem to get an editable summary item with an OnPropertyChanged event?

Good evening.
    I want to know if there's a way to save the end-user customization of a CommandBar Control. If the user removes a button, or change the disposition of the strips... when he closes the application, next time he wants to find the layout as it was. I didn't find a method to do this.

Thank you.
Franco

I have a radgridview that I want to change the background color of check box columns like the attached file.

Please, could you help me.

How can I make a gridview use all the width avaible in a flowlayout panel? the flowlayoutpanel is set to dock Fill, I set the gridview to dock fill too but it won't take the full width.

Thanks in advance.

Hello,

We have followed the recommendation from http://www.telerik.com/help/winforms/installation-deployment-and-distribution-redestributing-telerik-radcontrols-for-windows.html and merged all the required Telerik WinControls DLLs into one assembly using ILMerge.

Now the problem is that as soon as we change the references in our Visual Studio 2010 project from the Telelerik.WinControls.*.dlls to the merged assembly, the designer view of the form fails to load and crashes Visual Studio 2010. If the designer view is not loaded, we can run in debug mode, etc and there are no problems with the resulting application deployed with the merged assembly.

I do believe that perhaps starting developing a radForm from scratch using the controls from the merged assembly (rather than the Telerik DLLs) would probably have solved this issue. But we are too far into our development to strip away everything and start designing the forms from scratch.

I was wondering if anyone else has come across this? If so, do we have a way of fixing this?

We are using WinControls version 2010.2.10.806 with Visual Studio 2010.

Regards.
