hi,
You can write code in java script and use 'Registerstartupscript' for implementing that script.

I have created my own composite control, a "Color Check Box". I derived from UserControl and added a Picture Box (ColorCheckBoxButton) and a Label (ColoeCheckBoxLabel). I want the composite control to expose the Text property. The UserControl class already has a Text property, so I figure I must override it with the following code:
[Category("Appearance")]<br />
public override String Text<br />
{<br />
get { return ColorCheckBoxLabel.Text; }<br />
set { ColorCheckBoxLabel.Text = value; }<br />
}
Programitically this works and I can assign the Text property when I use the composite control. However, the Text property of the compiste control does not seem to be exposed in the Properties window of the VS designer when I user the composite control from the Toolbox. There appears to be NO Text property.
What am I doing wrong?
Thanks!

The Text property of the UserControl class has its Browsable attribute set to false, so you will need to add it (however this will create some serialization issues, so you will also need to add a DesignerSerializationVisibility attribute, set to Visible)...
[
Category("Appearance"),
Browsable(true),
DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)
]
public override String Text
{
get { return ColorCheckBoxLabel.Text; }
set { ColorCheckBoxLabel.Text = value; }
}
Cheers,
Will H

Thanks Wil! That worked! How would I ever have found that?
One more question. How do I change the Text property in the parent class (UserControl) now that I have overridden the Text Accessor method. If I do the following, it results in a stack overflow, because the parent accessor method is called recursively:
[Category("Appearance")]<br />
[Browsable(true)]<br />
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]<br />
public override String Text<br />
{<br />
get { return ColorCheckBoxLabel.Text; }<br />
set { ColorCheckBoxLabel.Text = value; this.Text = value;}<br />
}

Use base.Text instead of this.Text to pass the value to the parent class (this should work).
Glad I could help

How is MSIL code and .exe file is generated?

What? I don't get your question. Do you mean something like this?

It's an over-simplified explanation...But, when you compile your C# code, it's gets turned into MSIL code in the .EXE file. When you launch the .EXE, the MSIL code is then compiled by the Jist-In_time compiler in the .NET Framework into native machine code for the processor it's running on.

Hi,
can anybody help me in serialization of a ListDictoinary to XML, since it doesn't implement the ISerializable-Attribute  I'm still searching the whole www to find ideas but no one seems to face this problem.
I need to reconstruct the Dictionary with its special attributes so i can't use a arraylist.
thx

Hi
i am working in c# with infragistics
In c# windows applicaion, I will be passing data from textbox..such that
for example:i havE 3 texboxes labeled
name:
age:
salary:....
Now name is the parent and age and salary r the child..so if i pass data in
the appropriate textbox..It should be added in the ultrawintree.......such that
name(parent) should show up on the root node of the tree. and age and
salary(child) should show up under the root node.
so now when I run this program, as it reads a xml schema and creates a xml file.. now when I clicked the ADD button, it checks for the xml file and each textbox
is binded to the xml elements..so that the data which is passed in the xml file willbe added in the xml..
now for example i gave john,22,1800 for name,age and salary respectively and again john,45,3800
so it should be shown in teh tree as follows tht john under john both ages and salary should be shown
ie like
parent(name) : john
child(age) : 22 45
child(salary): 1800 3800
but i am getting teh result as follows..
john
22
1800 and again
john
45
3800 seperately.... so please tell me how to do it.
here is my coding part
//FUNCTION FOR ADDINGNODES
private void AddNode(string ParentNAME, string AGE, string SALARY)
{
//add parent node
Infragistics.Win.UltraWinTree.UltraTreeNode parentNAMEnode = new Infragistics.Win.UltraWinTree.UltraTreeNode();
Infragistics.Win.UltraWinTree.UltraTreeNode AGEnode = new Infragistics.Win.UltraWinTree.UltraTreeNode();
Infragistics.Win.UltraWinTree.UltraTreeNode SALARYnode = new Infragistics.Win.UltraWinTree.UltraTreeNode();
//add parent node
parentNAME.Text = ParentNAME;
//other nodes
AGEnode.Text = AGE;
SALARYnode.Text = SALARY;
//add childnodes to parent
parentNAMEnode.Nodes.Add(AGEnode);
parentNAMEnode.Nodes.Add(SALARYnode);
parentNAMEnode.Expanded = true;
//add teh nodes to teh ultratree
ultraTree1.Nodes.Add(parentNAMEnode);
}
//ADD button
private void button1_Click(object sender, System.EventArgs e)
{
DataSet dataSet = new DataSet();
// Read the existing xml
dataSet.ReadXml("..\\..\\resultdata.xml");
//PARENTName TEXTBOX
string strParentNAME = txtParentNAME.Text;
//AGE Text box----int type
string strAGE = txtAGE.Text;
int intAGE;
if (!strAGE.Equals(string.Empty)) // check to make sure the user entered something
intAGE = Convert.ToInt32(strAGE);
//SALARY Text box----int type
string strSALARY = txtSALARY.Text;
int intSALARY;
if (!strSALARY.Equals(string.Empty)) // check to make sure the user entered something
intSALARY = Convert.ToInt32(strSALARY);
//create a new row
DataRow newrow;
newrow = dataSet.Tables[0].NewRow();
// add new row.
newrow["ParentNAME"] = strParentNAME;
newrow["AGE"] = strAGE;
newrow["SALARY"] = strSALARY;
AddNode(strParentNAME,strAGE,strSALARY);
//add the row to the dataset
dataSet.Tables[0].Rows.Add(newrow);
//write the data to a xml file
dataSet.WriteXml("..\\..\\resultdata.xml", XmlWriteMode.WriteSchema);
dataSet.AcceptChanges();
MessageBox.Show("Saved");
}
//form load
private void Form1_Load(object sender, System.EventArgs e)
{
DataSet dataSet = new DataSet();
//read the schema
dataSet.ReadXmlSchema("..\\..\\Menu.xsd");
dataSet.WriteXml("..\\..\\resultdata.xml",XmlWriteMode.WriteSchema);
}
please help me to do this

Just a quick question. Is there an easy way to see if an object implements a particular interface? At the moment I am casting it and looking for an error Is there something like implements(object,interface) bool
Definitely a PEBCAK! (Problem Exists Between Keyboard And Chair)

if(obj is ISomeInterface) or, if you have a list or something similar:
foreach(ISomeInterface i in myArray) { ... }

Hi all ,
I need to disaplay a byte array within a datagrid
The array size could reach 500 bytes but I have only 16 COl in the grid
Is there a quick way to do this ?
Or should I run manualy on the grid and fill it ?
Thanks

Hiho
Are there good reasons available, to chose c# instead of vb?
Currently i know:
C#:
++
case sensitive
block-comments
cats
unmanaged code might be easier
closer to c++ / java syntax
arrays are defined in a proper way (elementCount instead of the index of the highest value)
unsigned datatypes
vb:
with
case insensitive (some guys think thats a benefit - im not so sure)
events might be easier
Is there some kind of in deep comparison available?
Maybe other reasons:
Member base of both languages might differ => but its rather hard to estimate both communities.
thx

I know for a fact that C# is more powerful and interfaces with all that the .NET framework offers, which VB .NET does not. If you're going to learn I new language, I would suggest C# since its used in industry extensively.

Really? That goes both ways.
For example, C# supports Unsafe code blocks, VB doesn't. VB supports optional parameters, C# doesn't.
It's just a matter of preference. They both target the .NET Framework quite well, each with it's own limitations.
I'd agree that learning C# would be very useful to him, but I'd also have to add that learning every language you can would be very useful to prospective employers even more so.

Sometimes its not so easy ;o)
I see 2 possibilities:
a) convince my boss that c# is better
b) convince myself that vb is as good or even better.
Thats the reason for my vb vs. c# comparison research.
thx

There are no absolute, water-proof and one-sided reasons for choosing C# over VB. As VB uses the same framework, anything you can do in C# you can also do in VB. For an example, the untyped datatypes that you mention is a part of the framework, so of course they are also available in VB.
It's more a matter of taste. The difference is how you do things, not what you can do. For an example the event handing is easier in VB, if by easier you mean less typing. If you want to be able to read in the code what happens, the C# way is easier.
BASIC (Beginners All-purpose Symbolic Instruction Code) was a simple interpreted language in the beginning. Many attempts have been made to make it compiled and object oriented, and perhaps VB is one of the best, but my opinion is that the language still suffers from it's history. C# on the other hand is a language that is compiled and object oriented right from the start.
