How do I loop this in a FOR loop

[=?Utf-8?B?aUhhdkFRdWVzdGlvbg==?=]

I have a textbox control in each row of the table and I need to display it
dynamically
In the first row of the table it is txtSample1 and in the second row it is
txtSample2

The below code is not working

for (int i = 0; i < ddlHowMany.Sele ctedIndex ; i++)
{
UserTable.Rows[i].FindControl("( txtSample)+(i)" ).Visible = true;
}

Plz help me out..

First time round, the code is looking for a control called txtSample0 which,
as you have described it, won't exist...

Re: How do I loop this in a FOR loop

Though I start from one the following code dosent work
UserTable.Rows[i].FindControl("( txtSample)+(i)" ).Visible = true;

I am not able to concatinate txtSample with " i " in the loop.

Any gusses.

Re: How do I loop this in a FOR loop

UserTable.Rows[i].FindControl("t xtSample" + i).Visible = true;

Your txtSample was inside brackets and the whole lot was inside quotes, so
you were literally looking for a control called (txtSample)+(i)

Re: How do I loop this in a FOR loop

I'm only guessing that this code will even work (the way you have it) but if
the first one is "txtSample1 " then you would need this:

UserTable.Rows[i].FindControl("( txtSample"+(i+1 ).ToString() ).Visible =
true;

Re: How do I loop this in a FOR loop

You should be ashamed of yourself Peter... you missed a closing bracket
somewhere... :-)

(Mind you, it won't actually do anything, as the bracket is inside a quoted
string, but even then, if it is called txtSample1, it won't be found with
(txtSample1 as your string. )
