Re: Report Viewer LocalReport GetParameters Function Evaluation Failure

To all those people out who where following along. I finally figured it out. Wow almost 8 hours on one little issue. After reverting some code and trying to pin point the issue, I finally got it.

This was NOT a C# coding issue. The issue lies in the RDL.

What I wanted was to be able to put special keys into the default value of report parameters. This was my default value <c>=CDate("%MyKey%") for a DATETIME report parameter. Then when reading this out of the rdl I was replacing the text %MyKey% with something like 4/2/2005. The resulting string would be <c>=CDate("4/2/2005"). Then this expression would go into my Expression Evaluation code and produce the result of 4/2/2005 into a DateTime object. Then I was going to loop through all the report parameters and set the default value of that datetime one as 4/2/2005. Which would result in the RDL loading properly. This is what I hoped for.

In all actuality when I try to loop through all the report parameters, the GetParameters function doesn't work because (I guess) it cant return all the parameters because there is one with an invalid default value (<c>=CDate("%MyKey%")). Well I dont know what I am going to do for report parameters other than strings.

You can not close it nor dispose it. It is like the mother form. If the mother dies all the children will die too.

You must keep on hiding it.

Why are u insisting to completly close it??

Any good reason for that??

Hi,

have a look at your Main method. Somewhere there you will find something like this:

Application.Run(new FormStartup());

Change it to something like this:

new FormStartup().ShowDialog();
Application.Run(new FormMainApp());

When FormStartup is done just close it and the other form will appear.

The functionality you're describing is called splash screen and there are some articles here on Codeproject that cover this topic and should give you some ideas how to implement this effectively and nicely. Just search the articles for "splash screen".

Inherit TabControl?

I'm inheriting TabControl in user defined class CustomTubControl, but when I try to open form with this control in Designer, I get error message: "TabPage cannot be added to a 'Microsoft.CompactFramework.Design.UnsafeControl'. TabPages can only be added to TabControls." on line:

this.m_Tab.Controls.Add(this.tabHeader);

Form builds, but it is not visible in Designer. How can the new control be visible in the Designer?

Hello,

The TabPage has to be added to the TabPages property of your TabControl.

this.m_Tab.TabPages.Add(this.tabHeader);

All the best,

I am having problem with control events.I am unable to raise overriden paint event.drag& drop event and mouse events.The control is dropped on a designer at runtime i.e control can be moved freely on the designer at runtime.

used delegate to raise the event but not working...

Hello,

Looks like you forgot to call the base.xxx Method of the overriden events.

like:

protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
{
    //Your code

    base.OnPaint;
}

Hope that helps!

All the best,

Martin

I have called base.xxx method.
Eventhough i have kept a breakpoint at the beginning of the method ,it doesn't go to the method itself.

Ohh, now I understand.

Youre control is in design mode, or not?
Don't think that the event's are fired in this mode.

Sorry for not realy helping.

Tell me how to get updated Coordinate position when control is dragged & dropped on any part of designer without using events.On designer also events are not getting raised.

Hello,

This is not going to work, because you are Disposing the form wich holds the reference to your new form.

Osama123 wrote:
this.Close();

Same here, because the Close method calls the Dispose method.

Osama123 wrote:
frm.Enabled=true;
frm.Visible=true;

This is normaly the default setting, so you shouldn't need it.(But it's not wrong)

Osama123 wrote:

this.Close();

You should use this.Hide() instead.

Hope that helps.

try this.Hide() instead of close and Dispose.

In the closing event of frmmdi use Application.Exit().

Hope this satisfies ur needs...

You won't get very far making a thumbnail of a wav file because it contains no image elements - it is an audio format.
