I'm having problems getting self-referencing data to display in my RadTreeView.  I'm using the Q1 2007 release in VS Team Suite SP1 on Vista 32bit.

I'm trying to bind the tree to a DataSet which holds the following Xml data:
<Toc>
  <Node>
    <Title>Main Title</Title>
    <Target>d03.xml</Target>
    <id>1</id>
    <parentId>-1</parentId>
  </Node>
  <Node>
    <Title>Child Title</Title>
    <Target>d0300000.xml</Target>
    <id>2</id>
    <parentId>1</parentId>
  </Node>
</Toc>

When using the Property Builder and selecting the DataSet as the DataSource, "Toc" as the DataMember, and Toc.Title as the DisplayMember then I get no items at all shown in the resulting WinForm.

When setting properties in code as below I get the title of the two nodes; however, no graphics or parent/child relationship are shown.

dataSet1 = new DataSet();
dataSet1.ReadXml("d03_toc.xml");
radTreeView1.DataSource = dataSet1;
radTreeView1.DataMember = "Toc";
radTreeView1.DisplayMember = "Toc.Title";
radTreeView1.ValueMember = "Toc.id";
radTreeView1.ParentIDMember = "Toc.parentId";

It's completely unclear in the help file if or how I'm supposed to use the Property Builder to create any nodes when using a bound data source.  Is this part of my problem?

I'd certainly appreciate a pointer as to where I've gone wrong.

Hi,

        My client has a requirement to have a 3rd Y axis, since the Rad Chart tool does not have this feature we planned of having a background chart to display the Y axis based on that we are trying to plot the series on the Foreground Graph.

We have  tried to handle this by using Prepaint Event of the chart Control..

The problem we are facing is that The Prepaint of the foreground is executed more than once when my mouse cursor is on the plot area.

Things are fine till this execution is correctly done , But some times the prepaint is executed more than once beacuse of the mouseover.

so ,
1. can some one please give us an overview of the complete Cycle of the Chart ploting
2. explain When and How the prepaint event is triggered and if there is a code where we can stop triggering this event that would also be useful.
Am Using C#.Net 2005.


-- Any Links or any Documents on this can be of great use to us.
-- Prepaint Event is what we are stuck with and This event is fired when i call mouseMove function also...

Thank u in Advance !! 
 

Hi there,

I have an application that needs to be built and the Outlook style of application is the closest I can get to explaining how our UI will work.
So far we will have the following:

1. A RibbonBar
2. A PageView for Navigating between subsections of the application (exactly like Outlook switches between mail and calender)
3. A SplitContainer to split the left side navigation from the actual content on the right

Where I get confused is:
I'm assuming the content that appears in the right side window (in Outlook's case this would be the mail items view, or the calender day view) should be built using separate windows. If that's correct do we load those windows as controls into the right side of the split container? (what is the norm when it comes to this kind of scenario?)
When we switch from Mail to Calender, how do we change the RibbonBar to be specific to that feature as is done in Outlook?

Thanks
Jacques

Hi,

We are trying to upgrade our project to the 2011 version, but having serious issues.
1. The VS extension fails with "Value cannot be null \n Parameter name: path1"
2. When using the upgrade tool the references are replaced correctly but there are problems with the way the grid displays:
columns' order is wrong, localization causes mismatch between data and headers!

Is there any code changes we must do in order to upgrade successfully?
Can we apply these changes automatically for our grids? Maybe the VS extension does that?

Thanks,
Hadar

I used the standard Windows Forms Property grid until now and am really happy about the new control, as the visual impression is now much more consistent.

One thought on boolean properties though: Would be nice if double click on the Text would toggle the value as it does in the Visual Studio Property Grid. Also the text (True/False) should be read-only for boolean properties.

Hello!

I found the following problem with the latest (v.2011.2 11.712) RadDropDownList:

The drop-down list is bound to the BindingSource. When I assign the binding source's DataSource to a list, the drop-down list control shows the first item but the SelectedItem and SelectedValue fields are still set to null as well as the SelectedIndex is set to -1. In the earlier version the fields were set to the corresponding values. If I assign the drop-down list's DataSource to a list directly, it works well.

This is very upsetting issue, because a lot of already tested code places becomes unstable unexpectedly. 

Thank you.

how can i select all text when i click the text on CommandBarDropDownList1 ?

thanks for your help..

I am building an application where users r coming from database in combobox on combobox1_Enter event.
I am also populating from another table rights for the particular user as per
selectedvaluechanged event of the same comboobx in datagridview.The problem comes when I reselect
same user error is"object not set to an instance of an object" this does not happen if I click buton for
populating usersrights in gridview when i select value in combobox.Can anybody help me with this?
here is the code:
private void UsersCombox_Enter(object sender, EventArgs e)
        {
            ds = null;
            UsersCombox.SelectedIndex = -1;
            SqlConnection mycon = new SqlConnection("Data source=DOTNET1;integrated security=true;initial catalog=examcollectiondata");
            SqlDataAdapter adap = new SqlDataAdapter("select * from createuserTbl", mycon);
            ds = new DataSet();
            adap.Fill(ds, "createusertbl");
            UsersCombox.DataSource = ds;

            UsersCombox.ValueMember = "CreateUserTbl.UserName";

            ds.AcceptChanges();


            ds.GetChanges();
            UsersCombox.Refresh();
        }

private void UsersCombox_SelectedValueChanged(object sender, EventArgs e)
        {
           //error when reselecting value in combobox
            SqlConnection mycon = new SqlConnection("data source=dotnet1;initial catalog=ExamCollectionData;integrated security=true");
//error comes in the line below
            SqlDataAdapter adap = new SqlDataAdapter("select DiffForms,selectdata,insertdata,updatedata,deletedata,viewreports from useraccesstbl where users='" + UsersCombox.SelectedValue.ToString() + "'", mycon);

            DataSet ds = new DataSet();
            adap.Fill(ds, "useraccesstbl");

            dataGridView1.DataSource = ds;
            dataGridView1.DataMember = "useraccesstbl";

Has anyone else gotten this error after saving the form with the RichTextBox and reopening the designer in Vs2010?
