0	Hi- This is not the way to assign values to the control. Steps to Add Values: (1) If you have added the control in a container control then find the control inside the container control. e.g you have added textbox in a panel named pnlControls. you can find controls as. (2) string strConstant="txtQty" ; for(int 1=1; i<=60;I++) { TextBox NewTextBox=(TextBox)(pnlControls.FindControl('pnlControls')); if(NewTextBox!=null) { NewTextBox.Text=i; } } Thanks & Regards Lakhan Pal Garg Shoyebaziz123, if this helps please login to Mark As Answer. \| Alert Moderator

{

TextBox NewTextBox=(TextBox)(pnlControls.FindControl('pnlControls'));

if(NewTextBox!=null)

0	Hi, As you are working with VB.NET, "+" will not work. It works with C#. You have to use "&" to concate strings in VB.NET. Here is what you can do. dim str1 as string="txtQty" dim str2 as string=".Text" Dim strArray1 As ArrayList for i as integer=1 to 60 strArray1.Add(str1 & i.ToString() & str2) Next Now youre strArray will be having 60 items with txtQty1.text to txtQty60.text Hope this helps..

Hi,

Here is what you can do.


dim str1 as string="txtQty" 

dim str2 as string=".Text" 

Dim strArray1 As ArrayList



for i as integer=1 to 60

strArray1.Add(str1 & i.ToString() & str2)

Next

Now youre strArray will be having 60 items with txtQty1.text to txtQty60.text

Hope this helps..

Thanks,
