  Dec 12, 2011 09:29 AM|LINK

  Hi,

  1. while typing the checkbox list not changing, it should be list autocomplete

  2. Multiple selection gives problem. Once i select any item the checkbox list closed. each time i can select only one checkbox.

  my code

  <div>

  <asp:TextBox ID

  ="txtCountry"

  runat="server" Skinid="longTextbox" AutoPostBack = "true"

  OnClientItemSelected="passtohidden()"

  ontextchanged="txtCountry_TextChanged" ></asp:TextBox

  >

  <asp:Panel ID="pnlLocation" runat="server"

  >

  <asp:UpdatePanel runat="server" ID="upLocation"

  >

  <ContentTemplate

  >

  <asp:CheckBoxList ID="chkLocation" SkinID ="chkColor" runat="server" AutoPostBack = "true"

  onselectedindexchanged

  ="chkLocation_SelectedIndexChanged">

  </asp:CheckBoxList

  >

  </ContentTemplate

  >

  <Triggers

  >

  <asp:AsyncPostBackTrigger ControlID="txtCountry"

  EventName="TextChanged"

  />

  </Triggers

  >

  </asp:UpdatePanel

  >

  </asp:Panel

  >

  <asp:PopupControlExtender ID="Panel1_PopupControlExtender" runat="server"

  Enabled="True" Position="Bottom" PopupControlID = "pnlLocation"

  TargetControlID

  ="txtCountry">

  </asp:PopupControlExtender

  >

  <asp:HiddenField ID="hdntypedtext" runat="server"

  />

  </div> <div>protected void chkLocation_SelectedIndexChanged(object sender, EventArgs e) { string strSelected = ""; foreach (ListItem l in chkLocation.Items) { if (l.Selected) strSelected += l.Text + " ,"; } //txtCountry.Text = strSelected; Panel1_PopupControlExtender.Commit(strSelected); }</div>

  Hello

  You may first debug to see without any event in TextBox, if the popup will close when you multi-select the checkboxlist. As you are in an UpdatePanel and the checkboxlist is autopostback, so the part of the page will re-rendered.
