Generate controls dynamically 1

[tyris]

hi all,

i wanted to know if there is a way to generate controls (like a textbox) into a for loop. This means that depending on the result of a query, i will get a number X , and will have to generate X textbox.
I'm affraid not but maybe am i wrong ... Hope so.

ie :

For i=0 to myDataset.Tables("Languages&quot.Columns.Count then
'create the textbox, and set myTextbox.name = ds.Tables("Languages&quot.Columns(i).ColumnName
Next

Create a placeholder. Name it 'plcControls'. Place it on the page where you want the textboxes to be, and this is where you'll add them:

dim txtBox as textbox
For i=0 to myDataset.Tables("Languages").Columns.Count then
    txtBox = new textbox
    txtBox.id = ds.Tables("Languages").Columns(i).ColumnName
    plcControls.Controls.Add(txtBox)
Next

What are you looking for?

I'm not sure if this will help, but you could always dynamically build a table to put the controls in. This way each text box could be in its own table row. I have some sample code if would like to see it and you think it might help.

Elise,

Here is some sample code that I hope will help:

I added a asp table to a form:

<asp:Table id=&quot;Table1&quot; runat=&quot;server&quot;></asp:Table>

Then in the code behin I added the following to the page load event to get three text boxes to show:

Dim ctr As Integer
For ctr = 1 To 3
'Generate table row &quot;<tr>
Dim tmpTableRow As New TableRow()

'Generate table data &quot;<td>&quot;
Dim tmpTableCell As New TableCell()

'Genereate Text Box
Dim tmpTxtBox As New TextBox()
tmpTxtBox.ID = &quot;txtBox&quot; & ctr

'Add text box to table cell
tmpTableCell.Controls.Add(tmpTxtBox)

'Add &quot;<td>&quot; to &quot;<tr>&quot;
tmpTableRow.Controls.Add(tmpTableCell)

'Add &quot;<tr>&quot; to table
Table1.Controls.Add(tmpTableRow)
Next

I hope this helps out. If you have any questions please let me know.

Ken
