Performance

Hello,

we use Telerik in our Company. We use a lot of GridViews and here are my Questions:

1. What is the best and fastest way to bind data to a datasource. We use lists for binding. Are datasets or arrays faster? Should i use   binding sources or do they cost time?

2. I have a hierachal GridView. I dont aant to work with datasets. I work with Objects.
    I have a class for example City with some properties and a nested list of people objects.

    Now my solution is to make an relation between thos two. Each people Object has an ID of its city.

    But to bind that i have to make a new list which has alle people from all cities and then i can bind it.

    But i would like to bind it without makin the new list.

    I wolud have it like the childgrid binds to the list of people in the city.

    gridView.datasource = List<City>
    gridView.Template...[0].DataSource = here I would like to have exactlöy the nested list in city but i have a list of alle people from all cities?

How can I solve that?
Thanx Thomas

RadApplicationMenu orientation

Is there any way to get the menu of the application menu to open horizontally to the right instead of vertically? I tried setting the DropDownDirection to Right, but that doesn't seem to do anything.

Thanks.

How to disable alt key

SetProperty(Me.RadRibbonBar1, "EnableKeyTips", False)

    Public Sub SetProperty(ByVal obj As Object, ByVal propertyName As String, ByVal val As Object)
        Dim t As System.Type = GetType(Telerik.WinControls.UI.RadRibbonBar)
        Dim flags As System.Reflection.BindingFlags = System.Reflection.BindingFlags.Instance Or     System.Reflection.BindingFlags.NonPublic Or System.Reflection.BindingFlags.[Public]
        Dim pi As System.Reflection.PropertyInfo = t.GetProperty(propertyName, flags)
        val = Convert.ChangeType(val, pi.PropertyType)
        pi.SetValue(obj, val, Nothing)

[Solved] Using GridView.DataSource and GridViewComboBoxColumn

Hi

I would like to know how I can use a GridView.DataSource with a GridViewComboBoxColumn.

private DataTable GridVDataSource = new DataTable();
**
**
This.GridView1.DataSource = GridVDataSource;
**
**

// Update GridView1 DataSource

private void button1_Click(object sender, EventArgs e)

{

GridVDataSource = " SQL operations ("SELECT StateID FROM State")";
}

However the StateID Column must be a combobox.
How can I change the column type to keep the combobox at each DataSource refresh?

If I created the column before :

private void form1_Load(object sender, EventArgs e)
{
GridViewComboboxColumn Combo = new GridViewComboboxColumn("StateID","");
Combo.DataType = typeof(int);

Combo.DataSource = StateDataSource; // Loaded before

Combo.DisplayMember = "StateName";

Combo.ValueMember = "StateID";

this.GridViewLanguages.Columns.Add(Combo);
}

When I refresh the DataSource (button1_Click) the GridView add the DataSource columns like news columns.

So, how is it possible to keep the initial combobox columns or to change them after loading the column type?

Thanks

[Solved] ToolStrip Localization

Hi,

Is it possible to localize the texts in the ToolStrip structure, I mean, ToolStripElements, ToolStripItems, and specially the OverflowManager elements?
I managed to change the "Add or Remove Buttons" in the DropDownMenu changing the Text property in Items[0], but then there are other levels (i.e.: Customize, Reset, etc.); it'll be great help if you can tell me how to change those texts in an easy way.
Thanks in advance.

Toolstrip (obsolete as of Q3 2010)
