[Solved] RadListControl SelectedIndexChanged Issue

On ListControl with SelctionMode MultiSimple the SelectedIndexChanged event fires whenever an item is selected, but only fires on de-selection when the items are de-selected in the reverse order that they were selected in. It's as if when selecting items it forms a stack (firing the event on each select) and when de-selecting items the event only fires if the item on the top of the stack is de-selected). Is there another event I should be using?

Top level font property no longer works.

Since Q3-2010 the font property on the RadButton doesn't work. However you can change the textboxitem element to set the font but can you explain why this is now the case ?

I haven't checked every rad control but the SpinEditor has the same issue...

Thanks

Paul.

DropDownList Size Issue

Hi

Since the new release of Q3-2010 controls I cannot set the Drop Down size to a manual size. I used to use the "DropDownMinSize" property but now it doesn't work. Neither does any other size related property for that matter.

Am I doing something wrong or has the Q3-2010 release stopped this property working ?

Many thanks

Paul.

RadForm - Rendering issue when no minimize, maximise or control box

Hi Guys,

I wonder if any one can shed some light on an issue I am having.

I have a form created from the RadForm template (2009 Q2), and if I turn off the ControlBox, MinimiseBox, MaximiseBox and then run the project the form renders with some of the desktop background in the form. If you add any one of these boxes back in the issue goes away. Is this expected behaviour? If so is there anyway around it? So far my only option seems to be leaving the ControlBox in place which the application does not really require.

I have attached a screen shot which shows the purple of my desktop wallpaper peeking through the form,

Thanks in advance.

Best regards,
Duane.

Want different node name from path generated

Hi,

I have a RadTreeView with a list of nodes, each of which should have a count after them.

Root (10)
-- Cars (20)
---- Ford (12)
---- Chrysler (2)
---- GM (30)

I realize I can use the tag to store a "value" for the node independent of the display format - I'm already doing that. However, when I export the data in the table, I make use of the convenient "Path" property to flatten out the hierarchy. Is there a way to generate the Path from the Tag property rather than from the Text property?

How would you go about exporting this to a list that looks like this?:

Root
Root/Cars
Root/Cars/Ford
Root/Cars/Chrysler
Root/Cars/GM

I'd rather not write the code to walk the tree and construct the paths myself - but it's the most practical solution I can think of.

[Solved] RadGridView loses format when it is updated.

Hi, in my program I have a RadGridView. Some of the cells are formatted with different backgroundcolor or they are disabled. The first time I bind the grid with data read from a table of a database it shows correct but If I update the grid it loses the format (All the cells are white and enabled) .

The cells are formatted according to this approach http://www.telerik.com/community/forums/winforms/gridview/createcell-event-cellelement-is-always-null.aspx (First it sets a tag for each cell in DataBindingComplete and subsequently depending on this value it sets backcolor and enabled properties for the cell.)

Here is the code (Cheers to Emanuel Varga for it):

void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)

{

if (e.CellElement.RowInfo.Cells[0].Tag != null && e.CellElement.RowInfo.Cells[0].Tag.Equals(true))

{

e.CellElement.BackColor = Color.Red;

e.CellElement.DrawFill = true;

}

else

{

e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);

e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);

}

void radGridView1_DataBindingComplete(object sender, GridViewBindingCompleteEventArgs e)

{

foreach (var row in radGridView1.Rows)

{

if (row.Index % 2 == 0)

{

row.Cells[0].Tag = true;

}

Thanks for the answers.
