Hi everyone,

I'm trying to insert a RadTreeView in a cell of my RadGridView but I can't make it work. I tried using RadTreeViewElement like a children of one of my CellElements but without success. Does anyone know where I can found an example or at least an explanation of how to do that ?

Thanks.

How to disable alt key

I got this code for disable alt key on the radribbonbar.

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)
    End Sub

However I got the error message "NullReferenceException".

I use VB2005, and I want to disable Alt hot key.

Do I have any idea??

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

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.

How do we disable 'filter assist' in the filtering row?

For columns that are strongly typed (set to System.DateTime, System.Double etc), when you click on the filtering row you get either a drop-down (for DateTime) or small up/down arrows on the right (for Double) which you can use to create your filter.

The problem is, these filters are causing the users more work than just typing the string -- selecting the date from the calendar dropdown or selecting a double value (which in our case have 3+ decimal places) gets hard. You can't just erase all that's in there with just a backspace (in the datetime case it erases only the year) and if you use the up/down arrows for doubles, they go up/down by 1.

I'm hoping there is a way to just disable these and make those filtering cells act just like a string filter. I would remove the types for those columns but that's not an option since I still want the columns to sort properly. I would appreciate your help in disabling the 'filter assist'.

Thanks,
Baris

How To Select Grouped Rows / Header Values?

HI,
can't find the answer to this anywhere so hope you can help.

I want to programatically expand a group when the user clicks on the group header (not just on the expand icon/button) and subsequently select all the rows in the group (multiselect is true already.)
I know I can use Groups[0].Expand() and use the Rows collection, but I can't find any way to get the index of the group when the user clicks on the group header.

I can detect that the user has selected a group header row by checking the type of the CurrentRow or using e.CurrentRow in CurrentRowChanged, but can't get any further.

I also want to get a value from the group header - e.g. if the GroupByExpression groups on CustomerName, how do I find the value of CustomerName when the user selects a Group Header row?

Many Thanks,
Jason
