Introduction

As a programmer we need to know about the static as well as dynamic controls. It's not necessary that always we will be using the static controls. Many programmers are having a mind setup like if they want the dynamic controls they have to write many lines of code but it's not like that.

Suppose we want to add dynamic control to a Panal control.So, what is the approach for that?

Following code will explain how to create the dynamic checkboxes.

Source Code:

//Drag and drop panal on the Webpage.

//After drag and drop following code will be generated automatically

protected System.Web.UI.WebControls.Panel PnlControl;

//Declare a CheckBox

CheckBox chkList1;

private void Page_Load(object sender, System.EventArgs e)

{

.

.

//Page load code goes here

.

.

}

#region dyanamic checkboxes

//Function to generate the dyanamic checkboxes

private void AddCheckboxes(string strCheckboxText)

{

try

{

if(PnlTimeExpence.HasControls())

{

return;

}

for(int intControlIndex=0;intControlIndex=5;intControlIndex++)

{

chkList1 =new CheckBox();

chkList1.Text = strCheckboxText;

chkList1.ID="Chk"+intControlIndex;

chkList1.Font.Name = "Verdana";

chkList1.Font.Size = 9;

PnlControl.Controls.Add(chkList1);

PnlControl.Controls.Add(new LiteralControl("
"));

}

}

catch(Exception exp)

{

throw new Exception(exp.Message);

}

}
