I want to check two conditions in the OnClientClick event of an asp.net button control. I tried this but it is only checking the first function.
OnClientClick="javascript:shouldSubmit=true; return checkFunction1(); return checkFunction2();
What is the correct way do it?
to fire the OnClientClick event of the asp button on the server side (with out clicking the button,it has to fire automatically based on the condition).
View 3 RepliesI am trying to call some javascript functions which I ahve written in some file. Eg.
function OpenPopup() {
alert("OpenPopUp");
return false;
}
when I call this from button from OnClientClick = "OpenPopup()" it is not called but when I put this function on MasterPage it is able to call the function.I added this is the MasterPages's Head
<script src="Scripts/something.js" type="text/javascript"></script>
I have an .aspx.cs page in my solution and I'm trying to call a function which is located in a Master page.Would anyone be able to offer any pointers on how to achieve this as I cannot figure it out - thought it would have been fairly straight forward!
View 3 RepliesI am using one webservice, which is for .NET platform, for address validation.Its running successfully on .NET (C#). However, I also want to use the same service from classic asp (legacy code) pages. Would appreciate if someone could give a clue how togo about it? Here are some ideas that I came up with and would appreciate if you could add to it
View 2 RepliesI have a JavaScript-based timeline which needs to use data from an SQL server. The queries and the JSON conversions have been worked out in the form of C#.NET functions within a code file related to an .aspx page. So for a complete newbie to ASP.NET, how do you set up a function call like this from JavaScript?I would love it if someone had some simple example code I could learn/get some pointers from.Edit: I am using .NET 3.5
View 1 RepliesI get this error: Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
Partial Class _Default
Inherits System.Web.UI.Page
<WebMethod()> _
Public Shared Function ParseData() As String
Dim value as string = GetValue()
End Function
Private Function GetValue() as String
Return "halp"
End Function
End Class
I know it has something to do with the fact that the first function is shared and the second function should probably be Public as well but I don't fully understand the reason behind it. Probably not relevant but I'm calling the web method from some javascript.
I have a user control which opens a new window for some item selection. Once an item is selected on that window, the item ID should be passed to a callback javascript function in the user control. In order to have a unique callback function name in the user control (it may have multiple instances on the same page), I added the user control ID to the function name as follows (defined in the ascx file):
function OnItemSelection_<%=this.ID%>(selectedItemID)
{
OnItemSelection("<%=SomeControl.ClientID%>", selectedItemID)
}
Where OnItemSelection is defined in an external js file:
function OnItemSelection(controlID, selectedItemID)
{
$(controlID).do_something(selectedItemID);
}
The issue is that now I'm not sure how the new page can call the "right" function (of the user control instance where it was opened from). The only idea I have in mind so far is passing the name of the callback function in the query string:
var CallbackFunction = function(selectedItemID)
{
window.opener.<%=Request.QueryString["CallbackFunctionName"]%>(selectedItemID);
}
or maybe just the opening user control ID:
var CallbackFunction = function(selectedItemID)
{
window.opener.OnItemSelection_<%=Request.QueryString["UserControlID"]%>(selectedItemID);
}
My questions are:
1) Is it a bad practice passing javascript function names (or user control IDs) like that (I suspect it is)?
2) What could be better way to handle this scenario? Edit: Another way I'm considering now is declaring a global variable in the user control (registering it from the code behind so it'll appear only once). Then, when opening the new window, it's possible to assign the relevant function to it (OnItemSelection_<%=this.ID%>), and call it from the new window. Seems much cleaner than passing user control data through the query string.
I have a page with three HTML labels and their corresponding ASP.NET gridviews contained within divs. Now while learning jQuery, I am trying to achieve two things:1. Change the css class of the lables upon mouse hover/out.2. Slide up/down the grid div upon clicking of the labels.It looks to be working as expected, but I wish to know if I am doing it the right way.My complete jQuery code is:
$(function ColorChange(ID) {
$("#" + ID).toggleClass("gridLabel");
});
$(function ShowHide(GID) {
$('#' + GID).slideToggle('slow');
});
And I am calling these function from onmouseover, onmouseout and onclick events of the label controls passing in the label ID as parameter. As an example:
<label id="lblWebComp" class="gridLabelDefault" onmouseover="ColorChange('lblWebComp')"
onmouseout="ColorChange('lblWebComp')" onclick="ShowHide('gvDivWC')">
Web Components
</label>
Kindly let me know if this is the best way to achieve these effects? Don't I have to right the document ready function in the jQuery code?
I have a page that contains a few user controls which all use an id in a querystring. I want to change this so that the page can send the id to the user control and can call a function on the user control.
Also is it possible for the user control to get the id from the page or a control on the page as its parent?
In the XHTML for a page I have:-
<asp:Button ID="bookNowButton" runat="server" CssClass="bookNowButton"
OnClientClick="showHideLoggedInDiv('<%=bookingFormDiv.ClientID%>')" />
This breaks. I need the correct syntax or method to insert the bookingFormDiv.ClientID into the control.
I have an Asp.net GridView (populate with a data binding).One of my columns is a ButtonField (obviously with his own CommandName).The *GridView_RowCommand* works perfectly, but if i add a *GridView_RowDataBound* (in which I simply add a javascript confirm) the *GridView_RowCommand* event is not fired in the PostBack.
Aspx code:
<asp:GridView ID="GridView1" runat="server"
OnRowCommand="GridView1_RowCommand"
onrowdatabound="GridView1_RowDataBound">
<Columns>
<asp:BoundField DataField="MyField1" HeaderText="MyField1" />
<asp:BoundField DataField="MyField2" HeaderText="MyField2" />
<asp:ButtonField Text="MyAction" ButtonType="Image" ImageUrl="myaction.gif" CommandName="myaction" />
[code]...
I have Onclientclick event attached to the button in serverside code like below,TopPanelButton.OnClientClick = string.Format("if(!ValidData({0},{1},{2},{3})) return false;", txtOD.ClientID, radCmbOD.ClientID, txtgetMe.ClientID, RadAjaxLoadingPanel1.ClientID);Also, the onClick event is attached for the same button in the aspx page,
<asp:Button ID="TopPanelButton" runat="server" Text="Go"
CssClass="CBtn1" Width="30px" Height="21px" OnClick="TopPanelButton_Click" />
The serverside click event should fire if the onclientclick return true. The "ValidateData()" function is called to validate the entries in the form.This code is working fine in IE. But in Firefox, both events are not firig. If I comment the "TopPanelButton.OnClientClick =..." code then onClick event is firing.
I have an imagebutton with an postbackurl and an onclientclick script. When i added the onclientclick code, if my javascript validation passes (aka returns true), the page just seems to perform a postback (the screen just seems to refresh
<asp:ImageButton ID="imgSendInfo" runat="server" SkinID="SendInfo" PostBackUrl="MyUrlOnAnotherSite" onClientClick="javascript:return onFormSubmit(this.form);return document.MM_returnValue" />
I decided to change what JS functions Im calling now since calling Multiple functions definately wasnt helping. Here's my updated code. All Im doing now is validating a single textbox and returning true or false. Even this simple function is causing the postback URL to never get called. Could it have anything to do with the fact that Im trying to call a function to return a true or false?
the OnClientClick event of a button on my page does not appear to be able to call javascript functions.

However the click function does not fire although if I put the alert directly in the buttons OnClientClick attribute it works.
I am trying to keep track of prints that are made for a page. The page has Print this page link. And the code for it is like below: This is written in .cs file as there are many conditions for displaying this. And i am appending here using String Builder.
sbOutput.AppendFormat("<td align="right" valign="bottom"><div style ="float:right;text-align:right; valign:bottom;width:200px"class="print_button notPrinted"><a class="notPrinted" href="#" onclick="window.print();">PRINT THIS COUPON </a><img src="images/print-icon-34x34.gif" class="notPrinted" align="absmiddle" /></div> </td></tr></table>", couponid, Userid, locationid);

I wanted to know if there's a way I can bind an Asp.net Ajax event to two different JS functions ?
eg.
var prm = Sys.WebForms.PageRequestManager.getInstance();

prm.add_initializeRequest(InitializeRequest2);
}

function InitalizeRequest2() { ... }
