Topic "Find grid row from bound index value?" a message from tttaff

I want to be able to search the grid for a specific record by its primary key. Currently I am doing a Find on the data source to search for the record with the primary key I want. The index of the record in the data source is returned, and I want to now select that row in the grid that corresponds to this record.

Please describe in more detail: In which situation do you need to find the TreeListRow for the BoundIndex and what do you want to achieve?

If I know the bound index value of a row in my data source, is there an easy method to find the corresponding row in the grid for that value?

What I'm doing for columns that I want to be display-only (no editing) is to just not assign an editor to the column:

If Not displayOnly Then
column.Editor = GetType(TreeListTextEditor)
End If

Is that what you mean?

Currently this is not supported - you can contact us for individual implementation if this of high priority for you.

Or is the AllowResize-property of the TreeListColumn what you are looking for?

I don't know what a Cellmodifier is, at least it is not supported. For editing cell-values please refer to the JFace-demos.

Topic "How to bind on disk images to TreeListImageColumn" a message from SiliconKid

Fri, 18 May 2012 08:10:18 GMT

Wait. Got it!

"AutoGenerateBoundColumns" was turned on and it was discarding my test image column and replacing it with a normal text column.

Sorry about that, I'm still getting used to the default settings on this Grid.

Topic "How to bind on disk images to TreeListImageColumn" a message from SiliconKid

Fri, 18 May 2012 07:56:27 GMT

I have an app that scans a whole bunch of folders for images and then creates a list of objects in memory with one of the properties containing the path to the image.

I want to bind that memory resident list to the grid and see those images.

I've tried various things, including making that property an Image, Bitmap and Byte[] type and I can't seem to get this to work.

What is the correct way to do this. What type does the property of the underlying bound object need to be, that is bound to the TreeListImageColumn, so that the grid will render the image and not show me a string value or some other value.

I took a quick look at the DataBinding demo and I see how a MemoryStream is used to derive a Byte[] which is then assigned to a column of this type, but I can't get that to work either so I'm obviously missing something.

Help me out here please.

Is it possible to fix column width, i.e. maximum width? When the grid resizes and columns are distributed, I want specific columns to stay at their predefined sizes.

Hello,

Is there a way to make a certain cell accept numeric values only? In other words, when the user types in, only numeric values will appear, other than that, everything gets ignored.

Thanks,
Michael

I have class Store, it has 2 properties - id and name, and I have ArrayList. I need to show and edit Store-objects in my tableViewer. I have no problems with showing, but I have big problem with editing. tableViewer has only 1 column for property "name" of Store-object. I have set everything for displaying data:

tableViewer = new TreeListTableViewer(treeListView);

CellEditor[] editors=new CellEditor[1];
editors[0]=new TextCellEditor(treeListView);
tableViewer.setCellEditors(editors);

MyCellModifier cellModifier=new MyCellModifier(tableViewer);
tableViewer.setCellModifier(cellModifier);

tableViewer.setColumnProperties(new String[] {"name"});

TreeListColumn column1 = new TreeListColumn(treeListView);
column1.setText("Name of store");
column1.setWidth(400);

tableViewer.setLabelProvider(new ViewerLabelProvider());
tableViewer.setContentProvider(new ContentProvider());

try {
refreshData();
} catch (ClassNotFoundException | SQLException | ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

but cellModifier is not called and changes don't reflect in Store-object when I finished edit. what I do wrong?

P.S. sorry for my English

Hell,

How can I validate the value filled in by the user in a certain cell. For example, I have a cell in my grid where only numeric values are allowed. How can I do this? I checked your XSL demo and I am using the same pattern. I am using a specific cell class derived from the DirectEditCell class.

Thanks,
Michael

Hello,

I have a question related to your .NET TreeListView control. I am using it for data entry. I need the user after finishing the entry in a certain cell, and when pressing the tab key, or the enter key to be taken to the next cell. When the cursor has reached the last cell in the current row, the focus should be moved to the first cell in the next row.

How can i achieve this?

Your prompt attention to this matter is highly appreciated.

Thanks,
Michael

Topic "Tooltips on columns" a message from tttaff

How do we get the new version (full version, not the evaluation version)?

Topic "Tooltips on columns" a message from admin

Sat, 12 May 2012 17:11:33 GMT

Currently not - we will add an event when an element is hoverred, then you can popup a Tooltip in this event like this:


private void treeListView_HoverElement(object sender, 
    Controls.Grid.Events.TreeListElementEventArgs e)
{
    if (e.RelatedElement is TreeListColumn)
    {
        // Show tooltip here
    }
}

A new version will be available this week-end (1.4.0.0)
