Hi,

I am setting the Maximum value of an NumericUpDown, but if user enters higher value, on lost focus it doesn't set value to maximum value. User needed to Focus-Unfocus the control to do this. (It works fine on first attempt, but not on next attempts...)
Am I doing something wrong ?

thanks,
dogu

COMBOBOX bINDING DISAPPERARS ON CLICKING ON THE CELL

I am trying to add a GridViewComboBoxColumn in radgridview dynmically usinfg the following code in my xaml.cs :

GridViewComboBoxColumn comboColumn = new GridViewComboBoxColumn();

comboColumn.DataMemberBinding = new Binding("CountryID");

comboColumn.ItemsSource = GetCountries();

comboColumn.DisplayMemberPath = "Name";

comboColumn.UniqueName = "Name";

comboColumn.SelectedValueMemberPath = "ID";

this.RadGridView1.Columns.Add(comboColumn);

private System.Collections.IEnumerable GetCountries()

{

List<Country> countries = new List<Country>();

countries.Add(new Country() { ID = 0, Name = "Germany" });

countries.Add(new Country() { ID = 1, Name = "Spain" });

countries.Add(new Country() { ID = 2, Name = "UK" });

return countries;

}

When we select some value from the combobox and move to some other cell the binding for the combobox disapperas.

Kindly let us know your view as we are in the process of evaluating telirik radgridview control for one of our future wpf product devlopment.

Pie Chart Grouping

Are there any examples of how to group data using the Pie Chart? All of my attempts end with the entire pie showing just one of the possible groups.

                                SeriesMapping seriesMapping = new SeriesMapping();         
                        seriesMapping.SeriesDefinition = new PieSeriesDefinition();        
                     
                        seriesMapping.GroupingSettings.GroupDescriptors.Add(new ChartGroupDescriptor("Baker"));         
                     
                        ItemMapping itemMappingValue = new ItemMapping("PieID", DataPointMember.YValue, ChartAggregateFunction.Count);         
                        seriesMapping.ItemMappings.Add(itemMappingValue);         
                     
                        ItemMapping itemMappingKey = new ItemMapping("Baker", DataPointMember.LegendLabel);         
                        seriesMapping.ItemMappings.Add(itemMappingKey);         
                     
                        RadChart1.SeriesMappings.Add(seriesMapping);         
                     
                        List<PieTest> pies = new List<PieTest>();         
                        pies.Add(new PieTest() { PieID = 1, Baker = "John", Crust = "Corn Meal", Filling = "Chili" });         
                        pies.Add(new PieTest() { PieID = 2, Baker = "Peter", Crust = "Graham Cracker", Filling = "Cream Cheese" });         
                        pies.Add(new PieTest() { PieID = 3, Baker = "Paul", Crust = "Graham Cracker", Filling = "Chocolate Cream" });         
                        pies.Add(new PieTest() { PieID = 4, Baker = "Paul", Crust = "Flour", Filling = "Apple" });         
                        RadChart1.ItemsSource = pies;         

So with my example, how would I show a pie chart that represents how many pies each Baker baked?

Problems with column generation

Hello, I want to generate columns of grid automaticaly. Everything works good except that generated colums have no data. Here is my code:

try
{
LoadDataTable = SqlHelper.GetTable(LoadProcedureSelectName, Args);
}
catch (Exception e)
{
CreateSelectProcedure(LoadProcedureSelectName);
}
LoadData(LoadDataTable);

protected void LoadData(DataTable dataTable)

{

dataGridView1.AutoGenerateColumns = false;

dataGridView1.DataMember = null;

dataGridView1.Columns.Clear();

LoadDataTable = dataTable;

dataGridView1.ItemsSource = LoadDataTable.DefaultView;

if (dataGridView1.Columns.Count == 0)

GenerateColumns();

}

protected void GenerateColumns()

{

dataGridView1.Columns.Clear();

dt = SqlHelper.GetTable("base_Fields_SelectVisible", new string[] { "@UserID", Globals.UserID, "@TableName", _TableName });

foreach (DataRow dr in dt.Rows)

{

if (dr["Type"].ToString().Equals("string"))

{

GenerateTextBoxWPF(dr);

}

private void GenerateTextBoxWPF(DataRow dr)

{

GridViewColumn col = new GridViewColumn();

col.Name = dr["FieldName"].ToString();

col.Header = dr["Caption"].ToString();

col.UniqueName = dr["FieldID"].ToString();

col.IsReadOnly = true;

col.Width = Convert.ToInt32(dr["width"].ToString());

dataGridView1.Columns.Add(col);

if (dr["Visible"].ToString() == "1")

{

dataGridView1.Columns[dataGridView1.Columns.Count - 1].IsVisible = true;

}

else

{

dataGridView1.Columns[dataGridView1.Columns.Count - 1].IsVisible = false;

}

What i do wrong. This technique worked very well with standart wpf grid and also with devExpress grid.

Undo Functionality in Grid

Hello,

I've implemented an undo capability into the grid. If a user changes the value of a field but they want to reverse the change they will click on the undo button and the change is undone. This undo functionality remembers only the last change. I've implemented this using List's and by clearing out the grid and re-building the grid using the data in the lists. It works but it's slow. Imagine re-building a 2000 row X 800 column grid. I tried saving the previous state of the data in the grid in another datatable and then getting rid of the current datatable and making this datatable the current one but I ran into many problems. Because rows and columns can be deleted the datatable rejectchanges() function is of no use.

Any ideals would be appreciated.

Thanks

Filter search mode no more working in 2009 Q3 SP1

If you open Demo application and select Grid --> First Look --> Filter near any column. As soon as you select a dropdown "Is Equal To" to change the mode you got an excetpion: Recursive Call to Automation Peer API is not valid.

I think this is a bug related to the combobox, I opened another thread this morning related to the fact that RadCombo is raising exception in this release.

Hope this helps,

drag treeview item to another control

Hello!

I am willing to buy your wpf controls, but before, I need to be sure that I do following stuff with it:

1. drag items to other controls than the treeview itself (for that case, if would be nice if I still would have the "drag tooltip")
2. being able to change the texts "drop in", "drop before", etc...
3. Do filtering (I explain here what I need):
I have the following structure:
aaa
   bbb
   ccc
      fff
ddd
   eee
I enter a filter criteria "fff". Will the node be displayed, even though the node "aaa" and "ccc" do not match the criteria?

Thanks for your quick answer.

Best regards,

Marc Wuergler

Docking Forms

Is there a way to dock normal WPF Windows in the RadDock like you can with the winforms implementation ? Is there a way to dock the Telerik RadWindow control at all ?

When I add items to the RadPaneGroup it always has to be a RadPane or iSplitItem.

I'm new to the WPF dock and really keen to get an old winforms application using RadDock for winforms upgraded to wpf.
