hi............
Mostly we make control design time, we handle many event
like click, mouseover,moueout etc. This is a easy process for design time
because there is not any need to attach event handler visual studio attach
necessary code automatically.
You can add control on run time………… for do this you will
have to perform following steps
- Make
an object of relevant control
eg. Button btn =new Button() [C# ]
dim btn as new Button() [VB.NET] - After
make an object of control you have to manage control property
eg. Location,size,backcolor,text etc - You can also attach events..
Add an Button
in C#
Button btn = new Button();
btn.Text="Click";
btn.Location=new Point(100,100);
btn.Click +=new EventHandler(btn_Click);
this.Controls.Add(btn);
following function will catch and handle
button click event….
private void btn_Click(object sender,EventArgs
e)
{
MessageBox.Show("Called");
}
Add a combo
box in vb.net
Dim com As ComboBox
com = New ComboBox
com.Items.Add("one")
com.Items.Add("two")
com.Items.Add("three")
com.Location = New Point(150, 100)
AddHandler com.SelectedIndexChanged,AddressOf com_click
Me.Controls.Add(com)
following function will
catch and handle combo box
selectindexchange event….
Private
Sub com_click(ByVal
sender As System.Object, ByVal e As
System.EventArgs)
MsgBox("Called
event")
End Sub
