             AutoPostBack="true" clientIdMode="static" 
             OnTextChanged="outros_TextChanged">
dados
</asp:TextBox>

Method pass data:

document.getElementById('outros').value = click_teste;

(function (marker, data) {
                      google.maps.event.addListener(marker, "click", function (e) {

                          var click_teste = data.title;
                          document.getElementById('outros').value = click_teste;



                          //alert(click_teste);

                          infoWindow.setContent(data.description);
                          infoWindow.open(map, marker);
                          alert(click_teste);
                      });
                  })

  • What is the moment that receives the value, has as an example?

  • I am using the Google Maps API, when I click on a marker I store the name of the marker in the click_test variable I pass this value to the other field and perform the query in the database using a gridview. The problem is that I have to perform the postback in the field other otherwise the gridview does not appear.

  • (Function (Marker, data) { google.maps.Event.addListener(Marker, "click", Function e) { var click_test = data.title; Document.getElementById('other'). value = click_test; //Alert(click_test); infowindow.setContent(data.Description); infowindow.open(map, Marker); Alert(click_test); }); })

You can use the "__doPostBack" function, example:

function suafuncao() {
    document.getElementById("<%=outros.ClientID%>").value = click_teste;
    __doPostBack("<%=outros.ClientID%>", "");
}

  • Hello marcelogribeiro, your code helped me partially, solved the postback problem but the gridview this dento of a modal and it ends up closing alone. how would you look to give the postback and keep the modal open? Function openModal() { $('[id*=modal_ICO]'). modal('show'); }

  • Try to place your textbox inside an updatepanel: <Asp:Updatepanel ID="Updatepanel1" runat="server"> <Contenttemplate> <Asp:Textbox ID="other" runat="server" Autopostback="true" clientIdMode="Static" Ontextchanged="outros_TextChanged">data </Asp:Textbox> </Contenttemplate> </Asp:Updatepanel>
