what is the use of Request.Form[""] in .net

Hi,

If you want to access client controls, you will use Request.Form[""].
For example,
You have an aspx page which contains some server side & client side side controls.
If you want to access server controls in .cs page, you can access by its id. but you won't in case of client controls.
So if you alse want to access this, you have to use Request.Form[""].

in .aspx page

<asp:TextBox ID="txtServerControl" runat="server" Text=""/>
<input type="text" name="txtClientControl" id="txtClientControl" value=""/>

now in .cs page:

string serverControlVal=txtServerControl.Text;
string clientControlValue=Request.Form["txtClientControl"];

Please mark as answer if you satisfied with the response.

Thank you,

Hi,
I agree with K Govindarao.But we can also access client control in code behind,if we add runat = "server" attribute in control definition as

<input type="text" name="txtClientControl" id="txtClientControl" value="" 
runat = "server" />

Now,we can access client-control value by their Value property as

string clientControlValue = txtClientControl.Value;

Kindly check this too.

Hi,
We can also access server-side control with request.form as

string serverControlVal = Request.Form["txtServerControl"];

So,Request.Form will be used for accessing both control values i.e. server and client side control values.

Hi,
If you take

<input type="text" name="txtClientControl" id="txtClientControl" value="" runat = "server"  />

and if this control is a page which has a master page then

string clientControl= Request.Form["txtClientControl"];

statement wont work.

Thank you,
Govind

Hi K.Govindarao,
You take client-side control but give an example of server-side control.
Kindly clarify these.
