I have few textboxes and one dropdown list . And am performing the onChange event on this drop down list, but it is refreshing the page, It should not why because while refreshing the page am loosing the previous text box values which we entered to submit and save into the database. It should not happen.

Thanks
ravi

0	Disable the PostBack property of the Dropdown list, then it will not refresh the page every time you change the value of the dropdown list... G. S. .Net Developer Ravinderk, if this helps please login to Mark As Answer. \| Alert Moderator

0	hi, I think the data in the text box persists after getting refreshed too.. Try this sample: ASP: <asp:TextBox ID="t1" runat="server" /> <asp:TextBox ID="t2" runat="server" /> <asp:DropDownList ID="dd" AutoPostBack="true" runat="server" OnSelectedIndexChanged="call"> <asp:ListItem Value="1" Text="1" /> <asp:ListItem Value="2" Text="2" /> </asp:DropDownList> CodeBehind: protected void call(object sender, EventArgs e) { Response.Write("hai"); } If this is not appropriate, could you post your code.

hi,
I think the data in the text box persists after getting refreshed too..

Try this sample:


 ASP:

   <asp:TextBox ID="t1" runat="server" />

   <asp:TextBox ID="t2" runat="server" />



   <asp:DropDownList ID="dd" AutoPostBack="true" runat="server" OnSelectedIndexChanged="call">

   <asp:ListItem Value="1" Text="1" />

   <asp:ListItem Value="2" Text="2" />

   </asp:DropDownList>



CodeBehind:



protected void call(object sender, EventArgs e)

    {

        Response.Write("hai");

    }

If this is not appropriate, could you post your code.

Regards,

Awesome Coding !! :)

0	@Vasanth, Thanks for your reply, Sometimes we have static texts like Dropdown list of Country or state where i dont want the page to be refreshed as it is client side scripting, for using that DropDownlist we will disable the autopostback properties of the DropDownList...

0	@Gopesh, Yes,In the case to represent static texts, where we dont include any event to occur. we set it as false. Also,The default value of autopostback is false. Regards, Awesome Coding !! :) Ravinderk, if this helps please login to Mark As Answer. \| Alert Moderator
