Accessing text field value

[flnMichael]

Hey,
I have a piece of code below in which I am creating multiple rows on a dynamic table, each with a number of text fields I have to gather on a button click. My question is how do I access each text field? I have named them according to a static name + the row number in which it falls into. How do I incorporate the row number in the name when I get to it in my loop?

int max_parms = 32;
int max_parm_count;
for (max_parm_count = 1; max_parm_count <= max_parms; max_parm_count++)
{
TableRow tr2 = new TableRow();

TableCell MSN = new TableCell();

TextBox _MSN = new TextBox();
_MSN.Width = 80;
_MSN.ID = "MSN" + max_parm_count.ToString();
_MSN.Text = "";
_MSN.Enabled = true;

MSN.Controls.Add(_MSN);
tr2.Cells.Add(MSN);
tblDynamic.Rows.Add(tr2);
}

TableRow row1 = new TableRow();

TableCell RunTestBtn = new TableCell();
RunTestBtn.HorizontalAlign = HorizontalAlign.Center;

Button _RunTestBtn = new Button();
_RunTestBtn.ID = "RunTestBtn";
_RunTestBtn.Text = "Run Test";
_RunTestBtn.Click += new EventHandler(_RunTestBtn_Click);
RunTestBtn.Controls.Add(_RunTestBtn);
row1.Cells.Add(RunTestBtn);

tblSaveQuitPrint.Rows.Add(row1);

private void _RunTestBtn_Click(object sender, System.EventArgs e)
{
int i = 1;
int flag = 0;

while(i < 32)
{
// This is the line I need to figure out
if(MSN+i.ToString() == "")
{
flag = 1;
break;
}

i = i + 1;
}
}

Any help would be appreciated.

Thanks
Mike

I am confused. Do you want to loop through and get the text that is in each of your textboxes?

 

[flnMichael]

that's exactly what I want to do. I have the ID being created, but don't know the syntax to get the value in it.

ex.
MSN1 --> value = 123
MSN2 --> value = 102
MSN3 --> value = rest

It's when I try to access then where I get confused. How do I syntactically say I want "MSN"+index in C#?

 

[jbenson001]

Try this:

if(MSN+i.Text == "")

when I do that, the only options I get are:

CompareTo
Equals
GetHashCode
GetType
GetTypeCode
ToString

I tried ToString, but this is tha error I get:

The name 'MSN' does not exist in the class or namespace 'TestScreen.WebForm1'

 

[jbenson001]

you may need to try

if((MSN+cstr(i)).Text == "")

I do not know the CSharp code to do this

basically convert the i (int to a string) concantinate to the "MSN" and try the .text

 

[flnMichael]

I still get the same error.

I also tried setting a temp string and setting it to the name:

test = "MSN"+i.ToString();

which will give it MSN1 (ex.), but when I try to access temp.Text I get:

'string' does not contain a definition for 'Text'

I belive you have to loop through the conrols on the page. This is VB code, but you can convert it easily to C#

   Dim c As Control
        For Each c In parent.Controls
           If c.GetType().ToString().Equals("System.Web.UI.WebControls.TextBox") Then
              Dim tb As TextBox
              tb = CType(c, TextBox)
              If Trim(tb.Text) <> "" Then
                 response.write(tb.id)
                 response.write(tb.text)
              End If
           End If
        Next c

Alright, I figured it out. Since I can access the table, row, and cell fairly easy I can cast it as a textbox:

temptext = (TextBox)tblDynamic.Rows.Cells[j].Controls[0]

with temptext being added at the top as a textbox.

Thanks for all the help!!!
