To add controls dynamically, create the control objects in code and then add them to the Controls collection for the current page.

Step1:
Add one panel to your page.
Step 2:
Create object of your Control
Button B=new Button()
Step 3:
Add properties that you need ....
like
B.Name="Test Button"
B.ID="Button1"
B.Text="Click Me"
Step 4:
Add Event Handler with the Control
B.Click+= new System.EventHandler(Button_click)
Tricks : After Write B.Click += Press TAB again TAB.... next part and Function body will create automatically
Step 5:
Add the control to your page
panel1.controls.add(B)
Step 6:
write function for Button_click
procted void Button_Click(Object Sender, EvnetsArgs e )
{
}
Steps 7: Run....

Is each row will contain Dropdown list and text box ???
if yes, then create a function the will generate one DropdownList and Textbox , Call that 10 times at form load and you can call the same on button click.
If it is not clear, then just give me the breif idea that what you are trying to do !!!
I will surely help you, if i Can !!!!

Thank you Abhijit.
Let me explain my scenario.
Basically this is for one application's Data Entry form.Each row will contain 2 Dropdown lists and 8 textboxes.10 rows shuold be loaded by default i mean at form load and a Addmore button will be there. If i want to add more data, additional rows will be added by clicking Addmore button.
(Dropdown list values shold be loaded from database.)
Can u help me?
(And i tried like what u have explained in ur previous post. But it doesn't work. Only one row is being loaded.)
Thanks & Regards,
Radha

> Create Runtime Table to maintain the allignment
>> Add Dropdownlist and Textbox inside each
[ That will create also in runtime ]
MAke this thing inside a function !!!
you have to use Table , Dropdownlist , and Textbox Classes Object . And it should be Array of Object !!!!
>>> Add Event Handler when you required !!!!
>>>> For Database Data, When you create the Dropdown list , use D.Items.Add() on that function itself.
>>>>> And on Button Click Call the same Function .....
--------------------------
For your reference!!
Dynamic Array of Button[^]
--------------------------
This will just add one row with that table..........
This is the simpliest IDea ....
One more idea ..... that you can create one Custom Web user control ....(ascx) file......
>>>>>>>
Regarding The Tricks ::: It was not about adding Column or anything else...
This is the .NET general Trick !!!!
e.g
when your write a if statement ....if have to write
if(condition)<br />
{<br />
{<br />
else<br />
{ <br />
}
Now just try this..
write if and press TAB
Check what the difference,similarly try with switch, for, while statement . and where i am talking there it will do the same thing...

Abhijit, Please check the code shown below and help me;
for (int i = 0; i < 10; i++)
{
Text1[i] = new TextBox();
//b[i].ID = i; //Can use ID
Text1[i].ID = "Text1" + i.ToString();
Text1[i].TextMode = TextBoxMode.MultiLine;
c1.Controls.Add(Text1[i]);
}
Here, i tried to add the text box to Table cell c1.
But, i dont get the result.
Did i miss anything here?
Thanks & Regards,
Radha

just read reocrds on Datareader , now
while(datareader!=null)
{
_dr.items.Add(datareadr[index].text);
}
This is a concept , you can try this,

Thanks Abhijit, But i did like this.
_dr.DataSource = GetData();
...
public DataSet GetData()
{
...
}
What i asked is.. when i click Submit button, all the 10 rows are inserted even if i enter Data only for 2 rows. I am inserting records based on the table rows count.
protected void btnSubmit_Click(object sender, EventArgs e)
{
int j = tblRunTime.Rows.Count;
for (int c = 0; c < j; c++)
{
string query = " INSERT INTO Time VALUES( ";
query = query + " '" + Request.Form["_dr1" + c.ToString()] + "', ";
query = query + " '" + Request.Form["_dr2" + c.ToString()] + "', ";
query = query + " '" + Request.Form["text1" + c.ToString()] + "', ";
...
query = query + " '" + Request.Form["text8" + c.ToString()] + "', ";
query = query + " '" + f_date_b.Value + "'";
query = query + " )";
}
So, how i can solve this?
Please help me.

create a table at runtime add rows into it and afterwards add the controls into the cells.
similarly u can do the same to create the single or more then one rows at run time.
all u have to do is to find the table id at runtime.
Hope this will help u.
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

Thank u Pankaj.
I tried this. Even, one row is loaded by default. and if i click to add a new row, a new row is added but first row disappears.
ddlActivity.ID = "ddlActivity" + i;
ddlActivity.Visible = true;
...
Text1.ID = "Text1" + i;
Text1.Visible = true;
Text1.Width = 40;
...
Table tblForm = new Table();
tblForm.ID = "tblform";
TableRow r = new TableRow();
r.ID = "r" + i;
TableCell c8 = new TableCell();
TableCell c9 = new TableCell();
TableCell c = new TableCell();
TableCell c1 = new TableCell();
TableCell c2 = new TableCell();
TableCell c3 = new TableCell();
TableCell c4 = new TableCell();
TableCell c5 = new TableCell();
TableCell c6 = new TableCell();
TableCell c7 = new TableCell();
c8.Controls.Add(ddl1);
r.Cells.Add(c8);
c9.Controls.Add(ddl2);
r.Cells.Add(c9);
c.Controls.Add(Text1);
r.Cells.Add(c);
c1.Controls.Add(Text2);
r.Cells.Add(c1);
c2.Controls.Add(Text3);
r.Cells.Add(c2);
c3.Controls.Add(Text4);
r.Cells.Add(c3);
c4.Controls.Add(Text5);
r.Cells.Add(c4);
c5.Controls.Add(Text6);
r.Cells.Add(c5);
c6.Controls.Add(Text7);
r.Cells.Add(c6);
c7.Controls.Add(Text8);
r.Cells.Add(c7);
tblForm.Rows.Add(r);
