Generating code in ASP.Net using "For"

[hpl]

I have some code looking like this in JavaScript:

<script language="JavaScript"><!--
								for (i=1;i<11;i++){
								document.write('<tr>');
								document.write('<td><select name="komp' +i+ '" style="WIDTH: 125px" onclick="click_komp();">');
									document.write('<% Do While Not Rs1.EOF %>');
									document.write('<option value="<%=rs1.fields(0).value%>"><%=rs1.fields(2).value%></option>');			
									document.write('<%Rs1.MoveNext()%>');
									document.write('<%Loop%>');
								document.write('</select>');
								document.write('</td>');
								document.write('<td><select name="dimen' +i+ '" onclick="saet_dim' +i+ '();">');
									document.write('<option selected value="none"> </option>');
									document.write('</select>');
								document.write('</td>');
								document.write('<td><select name="serie' +i+ '" onclick="calc_serie();">');
										document.write('<% Do While Not Rs7.EOF %>');
										document.write('<option value="<%=rs7.fields(0).value%>"><%=rs7.fields(1).value%></option>');			
										document.write('<%Rs7.MoveNext()%>');
										document.write('<%Loop%>');
									document.write('</select>');
								document.write('</td>');
								document.write('<td><input type="text" name="kappedim' +i+ '" class="resfelt" size="3" value="90" readonly></td>');
								//document.write('<td><input type="text" name="prisMedie' +i+ '" class="tastfelt" size="3" value="4,54" ></td>');
								//document.write('<td><input type="text" name="prisPeh' +i+ '" class="tastfelt" size="3" value="7,00"></td>');
								document.write('</tr>');
							}
							//--></script>

Now I'm writing an ASP.Net application which use server controls. How can I make some automated content like using "For..." in JavaScript?
