Hi,

I've noticed that you can check whether the selected font in the richtextbox is bold or italic, but not whether it is both bold and italic. Checking for bold or italic can be done likeso:

Dim style As StyleDefinition = SelectedEditor.CurrentEditingStyle

Dim fontWeight As TextStyle = DirectCast(style.GetPropertyValue(Span.FontStyleProperty), TextStyle)

btnFontBold.Checked = fontWeight = TextStyle.Bold

If fontWeight = TextStyle.Bold Then

btnFontBold.Checked = True

ElseIf fontWeight = TextStyle.Italic Then

btnFontItalic.Checked = True

End If

However, I cannot seem to find a way to check for both bold and italic text, as the only members of TextStyle are Bold, Italic, and Regular. Is there a way to do this?

RadTreeNodeComparer

Hi, I'm starting developing with Telerik WinForms and WebForms controls. First of all, I'm changin' a System TreeView for a Telerik TreeView. I wasn't hard, but, in my last Tree, I had one property for sort a custom level of the tree. I'd make a class NodeComparer that implements IComparer. Now, in Telerik, I read that this property is called RadTreeNodeComparer, and needs a class that implements IComparer<RadTreeNode>.

So, the code is like this:
UIPresentationTree.RadTreeNodeComparer = new NodeSorter();

Nothing happens, and the tree don't sort anything. What's wrong?

thanks.

Hierarchy grid child rows do not apply changes to data bound objects.

I am binding objects to a hierarchy grid in code and when a change is made a child row the change is shown in the grid, however, the underlying data object is not updated. I can manually apply the new value after edit to the object, but it seems like grid should be doing this for me.

public partial class Form1 : Form

{

private BindingList<Node> AllNodes = new BindingList<Node>();

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

LoadData();

}

public void LoadData()

{

LoadAllNodes();

grid.DataSource = AllNodes;

LoadAllObjectColumns(grid.MasterTemplate);

// Load child template

GridViewTemplate template = new GridViewTemplate();

LoadAllObjectColumns(template);

grid.MasterTemplate.Templates.Add(template);

GridViewRelation r = new GridViewRelation(grid.MasterTemplate, template);

r.ChildColumnNames.Add("Children");

grid.Relations.Add(r);

}

public void LoadAllNodes()

{

Node p1 = new Node("Parent 1", ItemStatus.None);

Node n1 = new Node("Child 1", ItemStatus.None);

Node n2 = new Node("Child 2", ItemStatus.None);

p1.Children.Add(n1);

p1.Children.Add(n2);

AllNodes.Add(p1);

Node p2 = new Node("Parent 2", ItemStatus.None);

AllNodes.Add(p2);

}

public static void LoadAllObjectColumns(GridViewTemplate template)

{

template.Columns.Clear();

template.EnableFiltering = true;

template.AllowAddNewRow = false;

template.AutoGenerateColumns = false;

GridViewTextBoxColumn colName = new GridViewTextBoxColumn("Name");

colName.HeaderText = "Name";

colName.Name = "Name";

template.Columns.Add(colName);

GridViewComboBoxColumn colStatus = new GridViewComboBoxColumn("Status");

colStatus.HeaderText = "Status";

colStatus.Name = "Status";

colStatus.DataSource = Enum.GetValues(typeof(ItemStatus)).Cast<ItemStatus>();

template.Columns.Add(colStatus);

template.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

}

public enum ItemStatus { None, New, Test, Complete };

public class Node : INotifyPropertyChanged

{

public event PropertyChangedEventHandler PropertyChanged;

protected void NotifyPropertyChanged(String info)

{

if (PropertyChanged != null)

{

PropertyChanged(this, new PropertyChangedEventArgs(info));

}

private string name;

private ItemStatus status;

private BindingList<Node> children;

public string Name

{

get

{

return name;

}

set

{

if (name != value)

{

name = value;

NotifyPropertyChanged("Name");

}

public ItemStatus Status

{

get

{

return status;

}

set

{

if (status != value)

{

status = value;

NotifyPropertyChanged("Status");

}

public BindingList<Node> Children

{

get

{

return children;

}

set

{

children = value;

}

public Node(string name, ItemStatus status)

{

this.name = name;

this.status = status;

children = new BindingList<Node>();

}

operator & not defined for string "select...." and data rowview

i have 2 ddls and i want to populate the second one based on the value of the first one. so i went on to use a row filter to filter the data view to get the data i need on the second ddl but when the page loads i get the error operator & not defined for string "Select distinct Zones....." and data row view. i click ok on the dialog error box to close it and it goes on to open the form and the code actually works. so how do i get rid of the error

cmd.CommandText = "Select Distinct Zones.ZoneID,CustomerItems.CustomerID as CustomerID,Zones.Zone " & _
"From CustomerItems Inner Join Zones On Zones.ZoneID=CustomerItems.ZoneID " & _
"Inner Join StockItems On StockItems.StockID=CustomerItems.StockID Where CustomerItems.CustomerID='" & ddlCustomers.SelectedValue & "'"
da = New SqlDataAdapter(cmd)
da.Fill(ds, "Zones")

'Populate Zones
ddlZone.DisplayMember = "Zone"
ddlZone.ValueMember = "ZoneID"
ddlZone.DataSource = ds.Tables("Zones")

setup = False
If Not setup Then
Dim dv As DataView
dv = New DataView(ds.Tables("Zones"))
'dv.RowFilter = "CustomerID = '" & ddlCustomers.SelectedValue & "'"
dv.RowFilter = "[CustomerID] = " & ddlCustomers.SelectedValue
ddlZone.DataSource = dv
ddlZone.ValueMember = "ZoneID"
ddlZone.DisplayMember = "Zone"
setup = False
End If

Auto suggestion box in Grid

Hello,

We currently have a field of our class that is the list of possible Texture that we can assign to a Sprite. It is a collection received by our Converter

class TextureConverter : ResourceConverter

{

public override StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)

{

Type[] tType = new Type[] { typeof(Texture), typeof(TextureAtlas) };

string[] tResource = ProjectManager.Singleton.CurrentProject.GetResourceNameListForType(tType, false);

return new StandardValuesCollection(tResource);

}

And our class member goes like this:

[Category("Settings Sprite")]

[DisplayName("Texture")]

[Description("Current Texture")]

[TypeConverter(typeof(TextureConverter))]

public virtual string Texture

{

get

{

return mTextureCBValues;

}

set

{

if (mTextureCBValues != value)

{

if (value == "")

{

ResetTexture();

}

else

{

Item tTex = ProjectManager.Singleton.CurrentProject.GetResourceByName(value, true, Name);

if (tTex is Texture)

{

mTextureCBValues = value;

SetTexture(tTex as Texture);

}

else if (tTex is TextureAtlas)

{

mTextureCBValues = value;

SetTextureAtlas(tTex as TextureAtlas);

}

else

{

SetStatus(Item.StatusState.ERROR, "Texture " + value + " is not found or invalid");

ResetTexture();

}

Refresh();

NotifyPropertyChanged();

}

How is it possible to make that field so we can "search" (auto-suggestion) for the texture name we want?

Retrieve bound entity [row] from gridview using entity framework

Wondering if there is a simple way to do this...

I add an object to my entity context but I have not saved changes yet. Therefore there is no ID or key associated to the entity.
I do however bind the grids datasource to the entities context. The data appears in the grid in the appropriate file.

However, if I want to modify or delete a row whereas the entity hasn't been saved, I can't execute a LINQ query or something to get the record; again because it hasn't been saved yet.

Is there a way to get and assign the entity based upon the row selected?

dim detail as Invoice_Detail = gridview.selectedrow(0).... Or something to that extent.

Thanks
Bob
