I am trying to bind the DataForm ItemsSource to a DataTable. Initially the DataForm is populated, but if I try to navigate through the records, I get an error.

I have spent past hour searching for a solution, and I could not find any mention of this issue. DataForm works fine if binded to an ObservableCollection of business objects. But in this case I need it binded to a DataTable, and I cant seem to find a way to get it working.

IDE: VS2010
.Net Version: 4.0
Telerik Version: 2011.3.1220.40

I have created a sample project that recreates the same issue. The error that I receive when navigating through the records is:

The type 'DataRowView' does not contain a public property named 'DateTime'.
Parameter name: propertyName


<Window xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"  x:Class="Testing.DataForm.MainWindow"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <telerik:RadDataForm Name="dataForm"/>
    </Grid>
</Window>

            DataTable baseTable = new DataTable();
            baseTable.Columns.Add("DateTime", typeof(DateTime));
            baseTable.Columns.Add("Value", typeof(decimal));
 
            DateTime date = new DateTime(DateTime.Now.Year, 11, 1);
 
            TimeSpan span = date.AddMonths(1).AddDays(-1) - date;
 
            int numDays = span.Days;
            int randHigh = 65;
            int randLow = 0;
 
            #region RANDOM DATA GENERATOR
 
            Random rand = new Random();
 
 
            int calculatedNumHours = 24 * numDays;
            for (int hour = 1; hour <= calculatedNumHours; hour++)
            {
                baseTable.Rows.Add(new object[]
                {
                    date.AddHours(hour).AddSeconds(-1),
                    rand.NextDouble() * ((randHigh - randLow) + randLow)
                });
            }
 
            #endregion
 
            dataForm.ItemsSource = baseTable.DefaultView;
 
            #endregion
        }
    }
}

Hi Aleks,

Thank you for reporting this to us. We have recently stumbled upon a similar issue with RadDataForm when ItemsSource is bound to a DataTable. We will do our best to implement a fix in 2 weeks and include it in an internal build. I will keep in touch with you, in order to notify you as soon as the mentioned IB is released.

All the best,

Hello Ivan,

I am running into the same issue with the RadGridView being bound to a DataTable. I am using build 2012.1.0326.40 of the WPF controls.

Can you tell us when on in which build this issue will be fixed? Is there a bug report in your public bug tracker so that we can follow the progress?

Many thanks,

Simon

Hello Simon,

 May I ask you to check what the behaviour is with the binaries from the latest release - Q2 2012? Would you please confirm if you use a code similar to the code posted when this thread was opened?

Do you have a working example of this with a DataSet as the back end now that you have fixes in?   I'm on 2012 Q3.

Hi,

We have a similar issue still logged into our system for fixing, so probably the issue was not fixed. We will re-evaluate the issue and hopefully we will be able to fix it.

What type of collection currently works?  I'd like to use this so I may just reload the tables into an object.  Does this work with a collection of dynamic objects?

Hello,

We will try to provide a fix for this issue in some of our future internal builds. As for the dynamics, RadDataForm supports them. I have prepared a very basic project to demonstrate.

Hi,

 I have the recent version of Telerik controls purchased last week. I am trying to bind datatable with radgridview and raddataform. However, when I select particular row in the radgridview, the row is not changed/selected in the raddataform below. Is there any property that we need to set? I went through the demos but it does not show any example using datatable but only collectionview. I also need some fields to be comboboxes which is not possible by binding with datatable. Is there any example where we can convert the datatable into collectionview with classes having enums, etc. as shown in the demo?

Hello,

You should set the RadGridView.ItemsSource/RadDataForm.ItemsSource to a DataTable.DefaultView.

Yes, but that doesnt allow for both Radgridview and Raddataform to work in sync for selection. If row is selected in Radgridview, that row is not selected in raddataform below. Is there any property that we need to set?

Hello,

You should set the CurrentItem for the DataForm to be the SelectedItem in RadGridView. That way the selection for both the controls will be synchronized.

You can also check our online documentation here.
