View 1 RepliesI have been trying to add and OnClick event to a Hyperlink. The problem is in both FindControl, they are not populating the hl and reportId variables. I have added the following to the RowDataBound method.
[Code]....
When clicked the client side addUsage OnClick event will pass the the variables to a Generic Handler as parameters.
formatting for an on click event in a hyperlink control:
[Code]....
I get an error with the using the <% %> within the onclick.
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)
is there a way after clicking on hyperperlink to do some code behind using an onclick event?

View 2 RepliesI have a Gridview looks like this:-
Region/Product/Q1/Q2/Q3/Q4
===============
US/A/100/200/300/400
UK/B/500/600/700/800
I want to turn 100,200,...600 etc into hyperlinks (I guess I know this part by using hyperlink field), and onclick 100, it will get the point parameters related to the value clicked (in this case, when 100 is clicked it gets US, A, Q1) and url to a new page with datasource parameter based on US,A, Q1

In my View, there is a HTML button; I would like to execute a function from Controller when user clicks on that button. I need to pass a value from HTML textbox as parameters. My function will do some calculating and return the result back to the same View.
Let's make a simple example.
I would like to input "1" in my textbox, press the button, pass "1" to controller, and in the function, I will do something like 1+1. At the end, I will pass the result, which is "2" back to the View.
I am programming in VB.NET.I am trying to make an onClick event for a div tag. How can I make this in the code behind?
View 2 RepliesI wanted to disable a button after it is clicked and at the same time fire the post back event to generate a report. My first set of code did not work because soon after the button is disabled the page won't submit/post back. here's the first set of code which was not implemented. the onclientclick calls a javascript function which has these lines
document.getElementById('btnGenerateReport').disabled=true;
GetPostBackEventReference(btnGenerateReport,'');
since it was not posting back,i tried the following on page_load code behind
btnGenerateReport.Attributes.Add("onclick", "this.disabled=true;" + ClientScript.GetPostBackEventReference(btnGenerateReport, ""))
that worked well. but I tried to copy the javascript that got generated and pasted directly on design view
onclick="this.disabled=true;__doPostBack('btnDownloadClientsWithConviction','');"
its not working from client side alone after I disable the code behind attributes.add
but when I check the view source the 2 pages are the samewhy am I not able to move the code from code-behind to design view?
have a user control that has a data repeater. When the ItemDataBound even is raised I create a html table which contains a button on each row. The button is created in a seperate class, not in the code behind, so when I attach the button click event I have to put the click method in the class that creates the control. However, when the button is clicked I need to open a modal form in the page that contains the button. How can I move the event back to the web user control with the sender object? I suspect I need to do something with a delegate or something, but I am having a hard time putting how to do that together. Can someone tell me how to do this?

I'm using a DevExpress control called DataView and within the ItemTemplate I bind all the appropriate information.

however, Void2_Button_Click not run, where is wrong?

I have an ImageMap control in an ascx file of mine. I'm trying to make something happen when the user clicks on an area in the map, but the page just posts back without my "imageMap_Click" event handler never being invoked.
<asp:ImageMap ID="imageMap" runat="server" ImageUrl="~/images/MapImages/map.jpg" HotSpotMode="PostBack" OnClick="imageMap_Click">
My imageMap_Click looks like this, just to see if it's invoked at all:
protected void imageMap_Click(object sender, ImageMapEventArgs e)
{
throw new NotImplementedException();
}
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'm modifying nopCommerce internet shopping software and I've a strange looking compilation error..
in file : CheckoutShipping.aspx I have:
<div class="button">
<asp:Button runat="server" ID="btnNextStep" Text="<% $NopResources:Checkout.NextButton %>"
CssClass="newaddressnextstepbutton" ValidationGroup="EnterAddress" OnClick="btnA"/>[code]...
I've double checked the if class name & code file in aspx and aspx.cs files match(and they do). Removing the OnClick part of the button declaration in aspx file (or changing it to ie. OnClick="Page_Load").What might be the reason for this? Do I have to register my functions somewhere?
I would like to add an Onclick event to one button (ShipEdit is the name of the button), I would like to redirect user by clicking this button to new page that is (../Account/MyAccount.aspx) and send 2 variables that is (LineItem.LineKey and shipment.ShipmentKey) with the URL: I need to write a code in this module:
void repShipments_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
I have tried to use this line of code but it does not working.
ShipEdit.Attributes.Add("onclick","ShowPopUp(" ../Account/MyAccount.aspx?LineKey={0}&ShipmentKey=",true);",LineItem.LineKey,shipment.ShipmentKey;
I am not sure how writing it with the ShipEdit.onclick, it gave me error anything that I tried.
