Dear All,
i want to add controls dynamically to my web form with the following code:

string sCtrl;
ArrayList alNewList=new ArrayList();
protected System.Web.UI.WebControls.RadioButtonList rdbtnlst;
protected System.Web.UI.WebControls.Label lblexec;
protected System.Web.UI.WebControls.PlaceHolder plholder;
ArrayList ctrlList=new ArrayList();



private void Page_Load(object sender, System.EventArgs e)
{
    if(! IsPostBack)
    {
        ctrlList.Add("Drop Down List");
        ctrlList.Add("Check Box List");
        ctrlList.Add("Radio Button List");
        ctrlList.Add("List Box");

        rdbtnlst.DataSource = ctrlList;
        rdbtnlst.DataBind();
        rdbtnlst.SelectedIndex =0;
    }
            alNewList.Add("Blue");
            alNewList.Add("Green");
            alNewList.Add("Red");
            alNewList.Add("Orange");
            alNewList.Add("Pink");
}


private void btnGetSelection_Click(object sender, System.EventArgs e)
{
    sCtrl = rdbtnlst.SelectedItem.Text;
    if (sCtrl !="")
    {
        switch(sCtrl)
        {
        case "DropDownList":
        {
        DropDownList objDDL=new DropDownList();
        objDDL.DataSource=alNewList;
        objDDL.DataBind();
        plholder.Controls.Add(objDDL);
        objDDL.SelectedIndex =1;
        break;
        }

        case "RadioButtonList":
        {
        RadioButtonList objRdbtn=new RadioButtonList();
        objRdbtn.DataSource =alNewList;
        objRdbtn.DataBind();
        plholder.Controls.Add(objRdbtn);
        objRdbtn.SelectedIndex =0;
        break;
        }

        case "CheckBoxList":
        {
        CheckBoxList objChkLst=new CheckBoxList();
        objChkLst.DataSource=alNewList;
        objChkLst.DataBind();
        plholder.Controls.Add(objChkLst);
        objChkLst.SelectedIndex =2;
        break;
        }

        case "ListBox":
        {
        ListBox objLstBox=new ListBox();
        objLstBox.DataSource=alNewList;
        objLstBox.DataBind();
        plholder.Controls.Add(objLstBox);
            objLstBox.SelectedIndex=3;
        break;
        }

        }//switch
    }//if
}

  private void btnClearSelection_Click(object sender, System.EventArgs e)
{
        sCtrl ="";
}


But am not able to display the controls.
Can anyone pls help me out.

Thanks & Regards,

You are not adding the controls to your form anywhere in your code.

this example shows how to add a textbox to a form:

Dim tb as new TextBox
tb.text = "This is my TextBox"
Me.FindControl("Form1").Controls.Add(tb)

Thanks but am not getting what exactly you are trying to say and what controls you are saying to add.
i already have a Radiobuttonlist, 2 buttons and a placeholder in the design view of the form as follows :

protected System.Web.UI.WebControls.RadioButtonList rdbtnlst;
protected System.Web.UI.WebControls.Label lblexec;
protected System.Web.UI.WebControls.PlaceHolder plholder;

string sCtrl;
ArrayList alNewList=new ArrayList();
ArrayList ctrlList=new ArrayList();


Cud you pls elaborate.

Regards,
Muskaan.

do you have autopostback = true on your rdbtnlst object?

yes, it is set to true.

So when the page loads or on a post back, none of your dynamic controls appear, is this correct?

I found your problem:

you define your array like this:
       ctrlList.Add("Drop Down List");
        ctrlList.Add("Check Box List");
        ctrlList.Add("Radio Button List");
        ctrlList.Add("List Box");

and bind it to your radiobutton list

Then, in your case statement you are checking like this:
case "DropDownList":

 case "RadioButtonList":
.. etc

Your case will never evaluate to a true statement.

you must use
case "drop down list"
case "check box list"

etc...

In other words .. "CheckBoxList" will never equal "Check Box List"

Hey THanks a lot.
its working fine now.

Glad it is working.
