Read Only Rows

Is there a way to make some rows readonly and other editable? Even better would be on the individual cell level.

I have the following scenario. I have a list of items that I need to display both horizontally, which is the normal grid behaviour, and vertically.

To accomplish this I have to build a datatable dynamically based on which option is selected. (horizontal or vertical).

When horizontal is selected I do not have a problem because I can set columns to be readonly. However when I display the data vertically I need the top row, with the exception of the first column which now acts as the headers, to be editable and all other rows to be readonly. I have attached screen shots to demonstrate

Thanks,

Billy Jacobs

Editable RadGridView Row

Hi there

Here is my problem and I hope someone could help me please:
- How can I turn a RadGridView Row with all cells in edit view and validate all entries at once?
The problem with the RadGridView is that we can only turn editable a single cell from a column that is at ReadOnly = false.
If there is a solution, please informe me ;-)
Thx

Programmatically expand/select node in virtualizing tree

Hi,

I want to check with you what is the right way to programmatically expand and select a node in a tree view which is using virtualization in recycling mode. The tree may be full of nodes and those nodes may not be visible on the screen at that moment.

Can you please provide a sample application which demonstrates how to achive that.

Thank you,
Ruben.

Ignore SelectionChanged event when rowloaded?

Is there anyway to ignore the SelectionChanged event from the GridViewSelectColumn when the grid is loading?

When the grid is loading, I make the row selected during the rowloaded event based on a value in the row (to indicate something was "selected" in past use of the grid). I then want to have code in the selectionChanged method that kicks off based on what happens to these rows after the grid is loaded from the user interaction, but i can't seem to figure out how isolate the code to run only during this time and not every time it is selected in the rowloaded event.

Thanks.

Change Column Header Text of Autogenerated Column

hy everybody,

I can not figure out how to change the column header caption of a column which was autogenerated since the radviewgrid's itemsource property is bound to a datatable. My code as listed below does not do the job.

with me.radgridview1
.columns(3).HeaderText = "Name"
end with

The headertext still shows the fieldname of the datatable.

Any suggestion is highly appreciated.

best regards,

Drag and Drop between Two TreeViews

I have a problem which only seems to occur when using the Telerik RAD tree views , instead of the standard WPF treeview control

On a basic level, I have an application that loops through an OLAP cube and returns data to the interface treeview. The treeview then displays the data in a format like below

+ Measure
Measure1
Measure2
Measure 3
Measure 4 etc

I want to be able to drag each individual node (e.g Measure 2 or Measure 3) into another treeview. However when dragging the measures, it drags the whole root (Measure) preventing me from separating the nodes.

Any idea how it could be made possible to drag individual nodes instead of the whole root??

The relevant XAML and XAML.cs is shown below

XAML

<Telerik:RadTreeView x:Name ="treeCube" IsDragDropEnabled ="True" Margin="250,174,41,158" Background="White" Telerik:StyleManager.Theme="Windows7" ToolTip="Drag" AllowDrop="True">

</Telerik:RadTreeView>

<Telerik:RadTreeView x:Name ="treeCubeTwo" IsDragDropEnabled ="True" Margin="0,174,-491,158" Background="White" Telerik:StyleManager.Theme="Windows7" Width="509" HorizontalAlignment="Right">

</Telerik:RadTreeView>

XAML.cs

private void LoadCube_Click(object sender, RoutedEventArgs e)

{

// get the cube schema

Helper helper = new Helper("demo01");

helper.Catalog = "Adventure Works DW 2008R2";

helper.Cube = "Adventure Works";

_cube = helper.GetCubeSchema();

// create an empty parameter set

_params = new ParameterSet();

// populate the left-hand treeview with cube schema

// measures

TreeViewItem measuresItem = new TreeViewItem();

measuresItem.Header = "Measures";

foreach (Measure measure in _cube.Measures)

{

TreeViewItem measureItem = new TreeViewItem();

measureItem.Header = measure.Caption;

measuresItem.Items.Add(measureItem);

}

treeCube.Items.Add(measuresItem);

Print preview table layout panel

Hi,

I have a form containing table layout control , I would like to print preview the tablelayout panel.
Currently I calculate the position of the controls and place them on the document for printing. But this will result in truncation of the controls which will not fit on the page.

Any samples will be of help.

Thank you.
