This has to be simple, but I'm stumped.

I want to drag and drop onto a RadGridView. I can determine the mouse position of where I have dropped:

                    Dim dropLoc As Point = grdDeliveries.PointToClient(New Point(e.X, e.Y))         

But I'm stumped as to determine which row this is as GridDataRowInfo does not give me the row index, or I can't work out how to get it.

Nor can I work out which part of the row I've dropped on. (column header, row header, cell, etc.) There is an enumeration 'GridViewHitTestType', but I can't work out how to use it. HitTest(x,y) just gives true or false.

In other words, what is the equivalent of the Windows DataGridView.HitTestInfo() within the Telerik framework?

radMenu Builder suggestion

it would be very handy if the radMenu builder had some way to move the items around in design mode, rather than saving, go to source, copy/paste items, go back to design, open radMenu Builder again...etc etc

Change text of the items in the context menu

I would like to change the text of the items

-Close
-Close All But This
-New Horizontal Tab Group
-New Vertical Tab Group

in the context menu of my document panes

I use the DockingManager with automatic MDI child detection enabled.

I just want to change it to another language, the functionality must remain the same.

Also, is it possible to remove the New Horizontal/Vertival Tab Group items?

Regards,

RadDropDownButtonElement scroll bar

Hello, I am running into an odd display issue with a dropdown element in RibbonBar. I am using the drop down to allow user to select font for text, and showing a preview of the text within drop down directly using the suggested code in following forum post (http://www.telerik.com/community/forums/winforms/ribbonbar/font-in-ribbon-bar.aspx).

While the text is showing up in the specified fonts, no scroll bar is appearing in the drop down, and the list takes up the entire height of the app. How can I get the scroll bar to appear, as well as limit the size of the list when drop down button pushed?

(as a side point, is it also possible to set the font size for each list item? Some of items the text is too small toread clearly...)

Thanks!
Justin

Dinamically changing a cell's backcolor

I'm working on a solution wich receives events that represent data from stock exchange.
I receive the data and list the quotes within the radgridview. What I want is to change the backcolor of a cell for around 500ms, to blue, if the price rises, red if it goes down and do nothing if the prices remains the same.
I have read the topics, and conditional formatting is not possible, because i don't have a static value to trigger the color change. Then I tried, as some topics suggest, changing the backcolor of the cell using the CellFormatting Event. However, when the values in the cell change, the event triggered is CellValueChanged, not CellFormatting. I was wondering if there is a way for me to raise the CellFormatting after I receive a CellValueChanged.

Thanks,

Alexandre

Rows property not in sync with sort ?

Dear Telerik team,

we have a RadGridView descendant, that delivers some new properties as shown in code below.
The attached images are to demonstrate the unexplicable behaviour. To generate the hint shown in the statusbar on the bottom of these images we used the following code that already uses our own indexer property:

string hint = HistoryGrid.MouseRow + " / " +

HistoryGrid.MouseColumn +
": IsProcedure = " + ((bool)HistoryGrid[HistoryGrid.MouseRow, "IsProcedure"]);

As seen on ALL images, row and column are always determined correctly, depending on where the mouse was during the screenshot.
(MousePointer not on image).

We use the hierarchy feature, so bold texts indicate that the entry is a procedure, containing child rows.
The status hint indicates that with its text.

While sorting is unchanged, ascending on column "Vom / Am", our indexer gets correct results (Images 1 and 2).
After sorting the same column descending (image 3), the indexer obviously addresses the wrong rows:
Row number is 4 (correct), but IsProcedure = true, incorrect, because row 4 in this sort order IS NOT a procedure.
Looks to us as if the Rows property of the RadGridView addresses the wrong rows after one did some sorting, is that possible?

Thanks to everybody with help on that.
Regards
Ron

Below the code we added to the RadGridView descendant:

internal object this[int rowIndex, string columnName]

{

get { return (rowIndex >= 0) ? Rows[rowIndex].Cells[columnName].Value : null; }

}

protected override void OnMouseMove(MouseEventArgs e)

{

base.OnMouseMove(e);

object currentCell = ElementTree.GetElementAtPoint(e.Location);

if (currentCell is GridDataCellElement)

{

var cell = currentCell as GridDataCellElement;

MouseRow = cell.RowIndex;

MouseColumn = cell.ColumnIndex;

}

else if (currentCell is GridGroupExpanderCellElement)

{

var cell = currentCell as GridGroupExpanderCellElement;

MouseRow = cell.RowIndex;

MouseColumn = -1;

}

else if (currentCell is GridExpanderItem)

{

MouseColumn = -1;

}

else

{

MouseRow = -1;

MouseColumn = -1;

}
