Hi,

How can I set the XML Data Source to RadGridView ? My XML is created dynamically so the number of columns may change each time.

Suppose if my XML has below format, how can I show it in Grid using XMLDataSource.

<ColumnA>Orange<ColumnA>

<ColumnB>Apple<ColumnB>

<ColumnC>Grapes<ColumnC>

<ColumnA>Banana<ColumnA>

<ColumnB>Carrrot<ColumnB>

<ColumnC>Onion<ColumnC>

So this will be a 2 row 3 column grid. I have to show this in XAML only. Any Idea ? Demo is not working in my browser.

Thanks in advance,

GridView

Get value(s) from cell to textbox

Private Sub rgv_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rgv.Click

        '
        ' Retrieve data to variable
        '
        dsId = rgv.CurrentRow.Cells("idRoute").Value.ToString
        dsDepart = rgv.CurrentRow.Cells("city1").Value.ToString
        dsArrival = rgv.CurrentRow.Cells("city2").Value.ToString
        'dsStatus = rgv.CurrentRow.Cells("status").Value.ToString

        '
        ' Set TextBox
        '
        tKode.Text = Format(Val(dsId), "00000")
        cbCity1.Text = dsDepart
        cbCity2.Text = dsArrival

    End Sub

Codes above works well on WindowsForms. My question is how to achieve same scenario with WPF?
I just want get some value(s) from grid to textbox based on column name as string.
Thanks.

Insert does not work, Delete is disabled by Devart.Data.Linq.Table<T> as ItemSource

I am evaluating your components and have tried the sample from "Tsvyatko's blog > Command Row for RadGridView with CRUD operations". I have used Devart.Data.Linq.Table<T> as ItemSource. The Insert command is enabled but does nothing, the edit is working and the delete command is disabled.
Should the source for grid to be ObservableCollection or to implement INotifyCollectionChanged this commands to work correctly?

Changing the editted cell value dynamically

Hi,
I am using gridview control for WPF. I have setted the validation condition for a column 'Capacity' for editting. The validation condition is that if you enter the '0' value for the column 'Capacity', one message box should be visible. The message box contains option 'Yes' and 'No'. If user clicks option 'Yes', then replace the entered '0' with '0.001'. So, how to set the editted value of cell from '0' to '0.001' dynamically.? I have tried using e.NewData = "0.001" in CellEditEnded method, but failed to do. Please help. It is urgent.

Chart legend item Names not showing

I have what I believe should be a simple problem, my legend items are just showing up as item0 - item6. I need them to show up with the name of the object in my items from the database.

I'm using a dataset to link to SQL, my 2 fields in my dataset are "sales" and "productclass".
I'm not sure what I missed, I followed the examples from the legend section exactly I think.

thanks for any help you can provide.

Cannot host multiple RadDocking controls in TabItems of a TabControl

I working on an app where I would like to have a Window with a single TabControl and a single RadDocking control in each one of its TabItems. This works as long as the docking control is the content of the TabItem control. As soon as something comes in between the two (such as the Grid control in the sample code), the exception below is thrown. Do you know if this scenario is possible? I'm using 2010 Q1.

                        <TabControl>         
                    <TabItem Header="Foo">         
                        <Grid>         
                            <td:RadDocking />         
                        </Grid>         
                    </TabItem>         
                    <TabItem Header="Bar">         
                        <Grid>         
                            <td:RadDocking />         
                        </Grid>         
                    </TabItem>         
                </TabControl>

Drag & Drop is causing Column Sizing to fail.

I've noticed that when I add drag and drop to a grid the column sizing no loger works.

I have implemented the drag/drop events..

private void OnDropQuery(object sender, DragDropQueryEventArgs e)
{

            Type sourceType = e.Options.Source.GetType();
            if (sourceType == typeof(GridViewHeaderCell))
            {
                return;
            }
        .
        .
        .

and
        #region dragQuery
        protected virtual void OnDragQuery(object sender, DragDropQueryEventArgs e)
        {
            if (sourceType == typeof(GridViewHeaderCell))
            {
                e.QueryResult = true;
            }
        .
        .
        .

How should the drag and drop respond to the GridViewHeader?
