Imagebutton With Onclientclick Is Not Firing Onclick Event
Jan 7, 2011
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?

I have a gridview which is bound to a dataset. I have placed several template fields in the grid with the following type of setup
HTML Code:
<asp:TemplateField>
<HeaderTemplate>
<asp:Label ID="Label1" runat="server" Text="File"></asp:Label>
<asp:ImageButton AlternateText="ASC" ID="imgASC" Width="10" Height="10"
ImageUrl="~/Modules/Interface/ASC.gif"
CommandArgument="eFolder ASC" runat="server" OnCommand="ImageButton_Command" />
<asp:ImageButton AlternateText="DESC" ID="imgDESC" Width="10" Height="10"
ImageUrl="~/Modules/Interface/DESC.gif"
CommandArgument="eFile DESC" runat="server" OnCommand="ImageButton_Command" />
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("eFileName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
on the code page I have mapped the OnCommand event to the following code
Code:
Protected Sub ImageButton_Command(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.CommandEventArgs)
Try
Dim img As ImageButton = CType(sender, ImageButton)
img.BorderStyle = BorderStyle.Ridge
SortOrder = e.CommandArgument
BindData()
Catch exc As Exception
ProcessModuleLoadException(Me, exc)
End Try
End Sub
My problem is that by clicking on the image button in the gridview header, the OnCommand event is not being fired. I have tried this with both OnClick and OnCommand and neither fires. I can't see what I am doing wrong if anything.

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" />

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 a navigation bar made up of ImageButtons that have their image swapped out on mouse over and back on mouse out. i used this code in the Page_Load handler to do this:
ImageButton1.Attributes.Add("OnMouseOver", "this.src='mouseover.gif'")
ImageButton1.Attributes.Add("OnMouseOut", "this.src='mouseout.gif'")
what i'm trying to do now is get the mouseover image to load when you click the button and are taken to the page. i tried this but it doesn't work:
ImageButton1.Attributes.Add("OnClick", "this.src='mouseover.gif'")

I have a Modal Dialog:
function ShowPopup()
{
window.showModalDialog('dialog.aspx', null, 'status:no;dialogWidth:950px;dialogHeight:150 px');
}
Then its called in the code behind
Page.ClientScript.RegisterStartupScript(this.GetType(), "popUpScript", "ShowPopup();", true);
The dialog.aspx has two buttons:
<asp:Button id="btn1" runat="server" Text="Button 1" OnClick="btn1_Click"></asp:Button>
<asp:Button id="btn2" runat="server" Text="Button 2" OnClick="btn2_Click"></asp:Button>
However, the Click events in the code behind are never getting fired.
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btn1_Click(object sender, System.EventArgs e)
{
Response.Redirect(url)
}
protected void btn2_Click(object sender, System.EventArgs e)
{
Response.Redirect(url);
}
}

I have two problems with a databound AJAX Accordion. The Accordion looks like this:
[Code]....
The code behind has this subroutine:
[Code]....
[Code]....
The first problem I'm having is that this subroutine is not fired (I have a breakpoint in it) when the LinkButton inside the accordion is clicked. The Page_Load event fires and there is no error message, javascript errors, etc, but nothing else happens.
The second problem is that I'm not sure how to go backwards with the databind. I want to be able to make use of the UpdateMethod in the ObjectDataSource because I also have textboxes inside the accordion. I will have a Save subroutine that can be called but I'm not sure what code to put inside it.

I came across a very strange occurrence with ASP.NET onclick event in IE (other browsers doesn't seem to have this problem). When there is only one textbox field in a form, the onclick event doesn't fire when you enter text and hit Enter/Return. The event does fire when you click on the actual submit button. When there are two or more fields in the form, hitting Enter/Return works just fine.

The <ItemTemplate> loads properly, and the line:
<asp:LinkButton ID="generalcomments" OnClick="SetPage_N_of_All" runat="server" PostBackUrl=<%#DataBinder.Eval(Container.DataItem, "Filename")%>> <%#DataBinder.Eval(Container.DataItem, "Title")%></asp:LinkButton>
loads the page correctly, BUT it does not fire the onClick event (OnClick="SetPage_N_of_All").
The method SetPage_N_of_All is in the codebehind page and is as follows:
public void SetPage_N_of_All(object sender, EventArgs e)
{
ContentPlaceHolder mpContentPlaceHolder;
TextBox mpTextBox;
mpTextBox = (TextBox)this.Master.FindControl("page_N_of_All.Text");
mpTextBox.Text = RobertBurns.DPM_Current.page_N_of_All;

I am using the following code to load user control on to ASPX Page, which under a Master Page:
[Code]....
The user control name is passed as a parameter on the URL.
Inside the user, there is a LinkButton. The link button has a simple server side code for OnClick event.
Everything is working fine on the production machine, but, on the Development machine, I can see incorrect behaviour. I have started making some development changes on the Development Machine since several months back, and it will be very difficult to find out what caused the problem.
When I click the LinkButton inside the user control, the user control is removed from the parent page, and the OnClick event of the LinkButton is not firing.
I did debug, and found out that after I click on the LinkButton inside the user control, then the Page Load events for the master page and the ASPX page are working fine, and the IsPostBack is set to true, but the OnClick event of the LinkButton is not firing.

I am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.

If I use both onclick() and onClientClick() can I make sure that server side will be called only after client side function returns TRUE or vice versa?
For example:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Import Namespace="System.Xml" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<%
protected void save_n_display(object sender, EventArgs e)
{
// This must be called when validate() returns true...
}
%>
<asp:Button ID="Button1" OnClientClick="validate()" onClick="save_n _display" "Text="Check" runat="server" />
<script type="text/javascript" language="javascript">
function validate() // client side Validation is done
{
}
</script>
So can I use onclick() and onClientClick() or do I need something different for this? I even tried passing variables from javascript to asp functions so when validate returns true then save_n _display will be called.

I have a button like the following,
<asp:Button ID="pagerLeftButton" runat="server" OnClientClick="disable(this)" onclick="pager_Left_Click" Text="<" />
When I use my button like that, onclick is not firing. When I remove OnClientClick, then onclick is firing.
What I need to do is, disable the button during the postback and enable it after the postback ends.
Edit: Additional information:
I added break point to my firing functions is c# part and I am debugging, they are not firing for sure. Those functions are like
protected void pager_Left_Click(object sender, EventArgs e)
{
//Do smthing.
}
protected void pager_Right_Click(object sender, EventArgs e)
{
//Do smthing.
}
and when I click my button, it is disabled for 1-2 seconds and automatically enabled, but I am not sure why it is enabled. I didn't add any part for it to be enabled again.

How do I setup a default setting so that if I do not set an OnClick (i.e the asp.net OnClick attribute) explicitly for an asp:LinkButton tag, it will not render an onclick(html attribute for javascript) attribute client side? By default, asp.net adds an onclick='doPostBack....' for the LinkButton.
Case for use:
There is a LinkButton tag on the page. For this page, if the user has one friend, I only want to run client side code if the button is clicked and would not for any reason want to make a post back. If the user has more than one friend I would want a click to trigger a postback.
Using any asp.net Ajaxtoolkit
Dynamically switching the control type (i.e. if friends == 1 use a asp:Hyperlink)
-I want to avoid this because it is not scalable. There might be many cases where I want an asp:Link tag to do a postback or to not do a postback depending on the user context or user attributes Using OnClientClick (I am using jQuery would like to avoid this)

I created an image button called "pic1" with the OnClick feature. When clicked it runs "btnClicked". In the sub "btnClick", how would I get information? One example is to get the button tooltip. I tried this: request.form.item("pic1.tooltip"). That did not work.
