Hello,
I am using the final release of .NET 3.0 to create a WPF application containing several Expander controls.
These expanders are customized by a central style:
<Style TargetType="Expander">
<Setter Property="Background">
<Setter.Value>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
<GradientStop Color="White" Offset="0.0"/>
<GradientStop Color="DarkGray" Offset="1.0"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
</Style>
As reaction to the MouseEnter event I am trying to animate the background color inside the expander markup:
<Expander Name="accountExpander" [...]>
<Expander.Triggers>
<EventTrigger RoutedEvent="Expander.MouseEnter">
<EventTrigger.Actions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="LayoutTransform.ScaleX" From="1.0" To="1.2" Duration="0 .1"/>
<DoubleAnimation Storyboard.TargetProperty="LayoutTransform.ScaleY" From="1.0" To="1.2" Duration="0 .1"/>
<ColorAnimation Storyboard.TargetProperty="Background.GradientStop[1].Color" From="DarkGray" To="SteelBlue" Duration="0 .1"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger.Actions>
</EventTrigger>
</Expander.Triggers>
</Expander>
Without the ColorAnimation the code is working perfectly, the problem seems to be property path for the Storyboard.TargetProperty. Before I switched to using central styles for the expanders I simply labeled the second gradientstop, which color I wanted to change, with the x:Name property. But as I declare the gradient stop inside a Style this is no longer possible. So i tried to use the longer property path syntax. According to the documentation it should be possible to access specific properties in an array-like fashion but the above code does not work for me.
Any ideas how I can animate the style-set property in my storyboard?
Thanks in advance

PS:
Somehow the board software seems to dislike XAML in its <code> tag so I hat to disable formating sorry for the ugly layout.

Hi everyone,
I have a textbox on a form with a Validating event handler attached. The textbox is bound to a data source. The code for the event handler is given below. Basically, the amount entered in the text field should not exceed the amount in the balance field. If this happens, error provider is set and Validating event is cancelled, giving the user the opportunity to correct the amount.
On the UI side e'thing is working fine, however I noticed that the data source is updated regardless, even if e.Cancel is set to true. That is a problem because the data source should never be set to an invalid value as it is taken as input for other calculations.
I expected that the data source would not be updated if e.Cancel is set to 'true'. Am I missing something?
Thanks,
Roel
private void textBoxCash_Validating(object sender, CancelEventArgs e)
{
if (Convert.ToDouble(textBoxCash.Text) > this.balance)
{
errorProvider.SetError(textBoxGenerateCash, "Cash exceeds balance");
e.Cancel = true;
}
else
{
errorProvider.SetError(textBoxCash, null);
}
}

Hi all,
Can I get any .net developpped library with proper UI, which gives the same functionality as DSO Framer control thats to display and edit office doc, xls etc files. Because the DSO Framer control uses unmanaged code which gives problem in web applications when hosted in clients local machine. So I need any .net developped tool to get these functioanlities done. I tried with aspose, but to change the document again we need to change the code, or we have to fight with sumo to make it independent of document format. So please
help me in this. You can email me at : aleem_abdul@akebonosoft.com. My requirement is to display the word or excel files in a browser, allowing user to edit it there only. He can email it from that page itself only only. Remember this page should contain a tool bar which contains appopriate buttons for those functionalities. The problem when I use aspose is, it doesnt have UI so occupies total page and if I want to change the format of the file(document), I need to change the code. And the problem with DSO Framer control is(it has nice UI but) it has to be installed on the client machine because it contains unmanaged code. By observing all these things please advise me.
Thank you.

Anything you impliment, will need to be installed on a client machine. Moving from what you've found to something .NET, will just mean your client will need .NET installed.

Yes dear but when you keep an acxtiveX control in your application, you need to install it too. That my client doesnt want, because to run an activeX control in a browser ofcourse its security need to be less.
So my client want an application, which uses only .net library and .net controls in it. So I need a tool made using .net and works same as DSO Framer. Could you please help me in this. I was in urgent thats why I put my queries 2-times. I will delete them soon after I get the answer. So please help me dear.

Please don't, it's SO annoying. Just post in the right forum only, to start with.

Is your client under the mistaken belief that .NET controls will just run in your browser ? They won't run at all, without the .NET framework installed. So, like I said, your end user will definately not be able to browse to your site without installing anything.

I answered your question, I can't change reality.

Just a little tip - in the West, guys don't call each other 'dear'. I am not upset or offended, but it's not a good habit to be in.

No.
He is right from his side, try to understan my problem. Ocx is built using un-managed code. But if I could get any thing similar to DSO Framer, and made by using .net framework. Because, he will install .net framework but for ocx browser settings has to be changed. Thats what I want. Once again I am repeating.
"I want a UI(control like label, text box any thing) which is made by using .net frame work and contains the functionalities similar to DSO Framer. And remember activeX controls are really not good to use. Its true, they are not that much secured and reliable. They have hell lot of problems. So please help me. And reply me whether its possible or not too. Even discuss with your friends too. But reply me soon, I am waiting for you reply.
I use the word "Dear" because this forum has helped me in too many ways. I cant even forget those supports. Thank you.

The answer is probably, no. If you can explain what you mean, then I'd be happy to say no with more force

I mean that you could have an application on a memory stick, plug it in and access a .net framework application without .net framework installed.
|
|
|
|
|
Nope. The .NET Framework MUST be installed to use an application that is based on it, meaning everything written in C#, VB.NET, or any other managed-code language targeting the .NET Framework.

I'm running into a bug in the DataGridView control, which happens only in the Release version of my code (ie, doesn't happen in the debugger).
Is there a place where I can read about known bugs/issues with various .NET components, and/or report the problems I'm seeing?
Thanks!

I want to change a string that appears in the status bar of the parent form on focus of a control(say check box or text box)in the child form.Please tell me how to do it?
|
|
|
|
|
Write a property in the parent form that set/gets the string of the control and assign values to it in child form.

for exmple create two form(From1,Form2)
1.in form1,put a button and make a object from form2 like this:
private void button1_Click(object sender, EventArgs e)
{
Form2 f = new Form2(this);
f.ShowDialog();
}
2.create a object of form1 like this:
private Form1 m_parent;
3.in form2, for example put a button then changed form2 constructor like this:
public Form2(Form1 frm1)
{
InitializeComponent();
m_parent = frm1;
}
4.in form2,inside of button click event you can change form1 property,like this:
private void button1_Click(object sender, EventArgs e)
{
this.m_parent.Opacity = 0.5;
this.m_parent.Text = "ok";
}
5.you being successed!!
be carefull:if you want to change a control on form1 first of all you must change Modifire property of control
to PUBLIC, then you can use of them.
if you need to full project that work right,Please send an email to me and write in Subject of your mail "CODE PROJECT Request"
then i send it for you
have a good time.
