Minimizing RadForm - LargeChange Error

[Kevin White]

I hope this is something I can fix or have a workaround for? I've not found much help on this error thus far and debugging does not work because as soon as it minimizes the entire application just crashes.

I have a RadGridView embedded in a Radform. With the latest version of Telerik Winform controls (Q3 2009), whenever anyone minimizes the application they are receiving the following Unhandled Exception (Taken from a user's error details) :

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

See the end of this message for details on invoking 

just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************

To enable just-in-time (JIT) debugging, the .config file for this

application or computer (machine.config) must have the

jitDebugging value set in the system.windows.forms section.

The application must also be compiled with debugging

enabled.

For example:

<configuration>

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

</configuration>

When JIT debugging is enabled, any unhandled exception

will be sent to the JIT debugger registered on the computer

rather than be handled by this dialog box.

Hi Kevin,

Thanks for contacting us and for reporting this issue.

I have tried to reproduce it but unfortunately to no avail.

Therefore, I would like to ask you to prepare a small Windows Forms application that we can use to investigate the case and see how we can help.

Thanks for your time.

All the best,
Deyan

Hi,
I have also had this reported by my users.

What has changed is that there are ever more columns on the Grid.

Interestingly the user was not using the app at the time. They had left their desk for about 10 minutes and came back to find the error.

I'm going to change the way I do scrolling today to see if that makes a difference.

thanks
mark

Hi,
an update already.
This is a hard problem for me now.

to reproduce: create a grid with a lot of columns. More columns than will really fit in the default size of the containing form.
Then simply minimize the form  and bang ....

This is the method that has the problem:

private bool UpdateHScrollBarVisibility(SizeF bodySize, SizeF vscrollbarSize)
{
    bool flag = false;
    TableViewDefinitionBase viewDefinition = (TableViewDefinitionBase) this.GridViewInfo.ViewTemplate.ViewDefinition;
    if (this.ViewTemplate.HorizontalScrollState == ScrollState.AlwaysHide)
    {
        flag = false;
    }
    else if (this.ViewTemplate.HorizontalScrollState == ScrollState.AlwaysShow)
    {
        flag = true;
    }
    else
    {
        flag = ((this.ViewTemplate.AutoSizeColumnsMode != GridViewAutoSizeColumnsMode.Fill) && (viewDefinition.DesiredSize.Width > bodySize.Width)) && (bodySize.Width > 1f);
    }
    if (flag)
    {
        this.hscrollBar.Maximum = (int) viewDefinition.DesiredSize.Width;
        this.hscrollBar.LargeChange = (int) bodySize.Width;
        return true;
    }
    this.hscrollBar.Value = 0;
    return false;
}

It has been passed a bodySize.width that is negative. and the property throws this exception when a negative value has been passed.
