Add control dynamically, runat = server?

qipilangza

I want to click Mon to dynamically add 4 controls. I originally wrote it in .cs and found that it will disappear after postback, so I put it in html. Now I want to get the value of text0, text1, text3 after clicking button2, but once str + = "<input id = id" + inputNum + "type = text name = text" + inputNum + ">"; becomes str + = " <input id = id "+ inputNum +" type = text runat = server name = text "+ inputNum +"> "; Can I get text0.value in .cs without runat = server?
<script>
var inputNum = 0;
function create ()
{
var str = "";
str + = "<input id = id" + inputNum + "type = text name = text" + inputNum + ">";
inputNum ++;
str + = "<input type = text name = text" + inputNum + ">";
inputNum ++;
str + = "<input type = radio name = text" + inputNum + ">";
inputNum ++;
str + = "<input type = text name = text" + inputNum + "> <br>";
ice.innerHTML = ice.innerHTML + str;
}
</ script>
....
<tr>
<td>
<asp: Label id = "Label3" runat = "server" onclick = "create ()"> Label </ asp: Label>
</ td>
</ tr>
....
<asp: Button id = "Button2" runat = "server" Text = "Button"> </ asp: Button>

Still have to write in .cs.

postback will disappear. It's because I added! This.IsPostBack. Just remove it.

runat = "Server" is explained by asp.net. It is useless to include runat = "server" in the html generated by the client.

According to the meaning of upstairs, it is to click the button to execute the dynamically added code first, and do it again in PAGE_LOAD?

Dynamically added code must be executed every time.

You can consider using JS to dynamically generate controls. And to get its value in the hidden code, you can use hidden to transmit!

It turned out that way, but using RESPONSE.FORM [HIDDEN1] produced an error

var str = "";
str += "<input id=id"+inputNum+" type=text name=text"+inputNum+">";
inputNum++;

ice.innerHTML = ice.innerHTML + str;
}
function setvalue()
{
document.getElementById("myHidden").value = document.getElementById("id0").value
}
</script>
....
<tr>
<td>
<asp:Label id="Label3" runat="server" onclick="create()">Label</asp:Label>
<input type=hidden id=myHidden runat=server>
</td>
</tr>
....
<asp:Button id="Button2" runat="server" Text="Button"></asp:Button>

Add when loading in the background:
Button2.Attributes.Add("onclick", "setvalue()");
Get the value in the click event of Button2 in the background:
string text0_Value = this.myHidden.Value;
