Hi,

Hi,

I'm having a problem with creating a complex filter expression in RadGridView.

The scenario can be described like this:
I have a DataTable containing columns Name (string), Address (string) and Finished (bool).
I'm giving the user the possibility to do a freetext search in the grid, where the user enters a text in a textbox, and I apply filters on columns Name and Address using Contains(entered string).

The above works fine. However, the problem is that I also have a checkbox "Show finished" that should always filter the data on the "Finished" column. I'm not able to get the correct filter expression for this, since when I add the Finished filter it's added as an OR filter with the other columns.

So in total I want a filter in the GridView that is something like this:
Finished=0 AND (Name LIKE '%text%' OR Address LIKE '%text%')
but I'm only able to get:
Finished=0 OR Name LIKE '%text%' OR Address LIKE '%text%'

Is this currently possible to do in some way?

Regards,

I have a WinForms application using a RadForm.  The form makes extensive use of the Rad Controls and when I resize the form to a small width I get the following error:
"{"Value of '-2' is not valid for 'LargeChange'. 'LargeChange' must be greater than or equal to 0.\r\nParameter name: LargeChange"}"

Any ideas on this?

I have a Calendar control that is contatined within a Tool Window.

The Tool Window is hidden on startup.

When the Tool Window becomes 'un-hidden' I need to refresh the calendar control, i.e. change back colour for some of the dates.

Trouble is I've no idea what event is going to give me the opportunity to do this:(

Can anyone help me out here?

Thx

RadGridView Columns sometime disappear.

For example:
I have set BindingSource, deleted not needed columns (leaving 2 TextBoxColumns on the GridView) and then added LookupColumn. When I have clicked OK button, the LookupColumn disappeared.

I have a RadDock control that contains Tool Windows, Document Windows and Shaped Forms.

I want to be able to display a list of hidden windows and restore them to their pre-hidden state.

Questions :-

- Is there a list of these windows somewhere or do I have to track the windows that are hidden?
- If I need to track the windows that are hidden how do I do that?
- Any suggestions as to which control would be best suited to display the list of hidden windows, i.e. if you've done it before, used a particular control and it worked well

Thx

Ok i have an array that i bind to the chart, with the following values

17
18
0
0
0
22
23
0
24
0
0
21
0
18

I know there is supposed to be an EptyValue property that approximates the empty (0 ???) values, but how can i use it ?
Currently i don't see any results on the chart
I use a bar chart and as it is now, the 0 values do not get approximated

It drives me absolutly crazy when I make a change in the design mode and the change doesn't show up when I debug it. Where does Telerik store the settings for the UI at? I know its a binary file somewhere, I have came across it before and I know If delete it, it will be rebuilt with the latest settings. I hate spending 20 mins having to trick the Telerik stuff into working and I am a little frustrated. I know I could explain in greater detail what is going on but first I would really like to know where the settings file is.

The following link points to a Visual Studio 2008 VB.NET project that demonstrates some grid editing problems. I need advice on these problems.

http://www.glt1.com/gl/misc/GridView20091207.zip

Here are three sets of steps to produce the problems:

Run the project
Click in the "Row Text" column of the third row. The row is highlighted as expected.
Click again in the "Row Text" column of the third row. The cell goes into edit mode. The row size decreases so that the cell editor is only a single line. The row SHOULD have remained the same size.
Click in the "Row Text" column of the first row. The cell goes into edit mode as expected.
Click in the "Row Text" column of the third row. The cell goes into edit mode as expected, while remaining the correct size. It seems to stay the correct size from this point on, that is, the downsizing-to-one-line problem seems to occur only when going into edit mode for the first time.

Run the project
Click in the "Row Text" column of the third row. The row is highlighted as expected.
Click again in the "Row Text" column of the third row. The cell goes into edit mode (and the row sizing problem is evident once again).
Click just to the left of the first letter ("R") in the "Row Text" column of the third row. The cell text un-highlights and the caret is positioned at the beginning of the cell text as expected.
Press the left arrow key. The cell focus moves to the first column (skipping the read-only second column) as expected.
Press the left arrow key again. The cell focus moves very briefly to the "Row Text" column of the second row, but then quickly moves to the checkbox column of the second row. The cell focus SHOULD have stayed on the "Row Text" column of the second row.
Press the left arrow key again. The cell focus moves very briefly to the "Row Text" column of the first row, but then quickly moves to the checkbox column of the first row. The cell focus SHOULD have stayed on the "Row Text" column of the first row.

Run the project
Click in the "Row Text" column of the fourth row. The row is highlighted as expected.
Click again in the "Row Text" column of the fourth row. The cell goes into edit mode (and the row sizing problem is evident again).
Click in the "Row Text" column of the third row. The cell is focused as expected.
Click anywhere on the third line of text in the "Row Text" column of the third row. The cell text un-highlights and the caret is positioned on the third line of text as expected.
Press the up arrow key. The caret moves to the second line of text in the cell.
Press the up arrow key again. The cell focus moves to the "Row Text" column of the second row. The caret SHOULD have moved to the first line of text in the "Row Text" column of the third row.

I'm trying to pop up a MsgBox in a GridView's CellValidating event. like this:


The event keeps firing over and over, causing the MsgBox to appear "a million" times, and finally, the MsgBox AND the Form that contains the GridView both lose the text in their title bar.

I can use a flag like this:


...and it works correctly, as long as I am trying to navigate away from the cell to some other element in the grid. If I click on any other control on the form, I get the message twice (???) but then the focus still goes to whatever other control it was I clicked on. For example, I have a "Close" button on the form, and I want the user to be able to click it to cancel their edits and not get the validation MsgBox, but instead I want to show a "Discard changes?" type dialog. Any ideas?

PS: If possible, please provide tech specs on exactly what causes the event to fire, such as the gridview losing focus, etc.
