Hello,

I have an MDI parent form with a radcommandbar across the top.

The commandbar contains 2 commandstripelements which have several buttons

One is left justified and one is right justified

Everything is working fine except when I deploy it to a touch enabled / touchscreen client.  Some users are accidentally dragging the commandstripelements into one another and even dragging them off the command bar making them disappear entirely.

Is there a way to disable dragging or reordering of the commandstrips.   Ideally I don't want any of the items to move at all

I have already tried

For each commandstripelemnt I set

            commandBarStripElement1.AllowDrag = false;
            commandBarStripElement1.AllowDrop = false;
            commandBarStripElement1.EnableDragging = false;
            commandBarStripElement1.EnableFloating = false;

For each button in either strip element I set

buttonX.AllowDrag = false;

I even tried returning e.Canceled in BeginDrag

Nothing seems to be working 

Any help would be appreciated

 

Thanks

Kevin

Hey there!

I was tasked with fixing the memory leak problem of some programs, and since they have more than 100k lines combined i wanted to know something before starting :D

I want to make sure that this is the correct way of clearing/cleaning an object:

/**************************/

tmpPanel:Dispose().

tmpPanel = ?.

IF VALID-OBJECT(tmpPanel) THEN DELETE OBJECT tmpPanel NO-ERROR.

/**************************/

Am I missing something? Do I need to do anything else?

And can I do this dynamically? By sending the object in an argument and running the "Dispose" method by invoking it. Does that work as well?

And If i assign the object i want to clear/clean before doing clearing/cleaning it to another variable, should I also clear/clean such variable?

Hi there ,

I have a WindowsForms application with a RadGridView.
Now I would like to output the filtered values ​​as a report or transfer them to a report.
Is there an easy way?

Thanks

************** Depuração JIT **************
TO active depuration  just-in-time (JIT), the file .config 
for this app or computer(machine.config) needs to have the value  jitDebugging definido na secção system.windows.forms.
THe application also needs to be compiled with the depuration activated.

FOR EXAMPLE:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When it's activated, any non processed exception will be sent for the JIT instead using the dialog box.

 

 

--------------------------------------------------

IMAGE TEXT TRANSLATED:

A not processed exception occurred. If you click "continuar" the app with ignore this error and will proceed. If you choose the other option  the app will be closed instantly.

The collection was modified; the enumeration operation may not be executed.

The client is using the 2019 version.

I'll wait for your response.

How can I get all parent rows to expand when the search criteria is met?  Currently, only the parent of the first occurrence of the search result expands.  

Other parents have to be manually expanded to see if the search was found.

Thanks

I'm enjoying the rich function available in the RadSpreadsheet, but as so often with the Telerik framework, it's the simple stuff which I find hard.

Yesterday I spent a few hours trying to discover how to get the value of a cell, where I don't know if the cell has a forumula, or is just a value.

Something like:

myString  = myWorksheet.cell(2,3).value.     (I know this doesn't work - it's just what the code should look like in my head).

So just pick one cell, and return what's visible to the user. I've looked through all the examples, and can't seem to find this one.

Just curious, as I'm going to add that to my application and figured if there was a control that you did, it'd be better than the default NotifyIcon and I'd rather use that.
