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)
Void button has a confirm box after receiving true, expecting running another button's click event
however, Void2_Button_Click not run, where is wrong?
protected void Void2_Button_Click(object sender, EventArgs e)
{
// do something
}
Void_Button.Attributes.Add("onclick", "var agree=confirm('Confirm to void?'); if (agree){document.getElementById('Void2_Button').click();}");
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'")
Note: The answer marked as the answer, answers the questions in the Title. However, my underlying problem, using type ahead dropdowns, is solved by moving to IE8.
I have a drop down list that when I CLICK a NEW selection I want to cause a postback ("this.form.submit()") But only if the click on the dropdown list just changed the selection.
Note that OnChange will NOT work because when the selection is changed by the keyboard I would not want to postback because it is a type ahead dropdown list.
I also suppose I could use OnChange and check if the change was caused by the mouse.
Maybe if we can come up with both solutions and i'll see which works better?
EDIT: More information:
AutoPostback = true; will not work. (don't want it to post back when the selection is changed by the keyboard)
onBlur = doPostBack; I tried this, but the result is not optimal. The user has to click off the ddl after making a selection with the mouse.
Another way to state what I want to do, i think, is do a postback when both the OnChange and OnClick events fire at the same time.
I have a html input button like this
<input type="button" id="send_button" class="form_button" value="Send" onclick="return validateTextBoxes();" runat="server" />
And also I have javascript
[code]....
And I am also calling this server click event in the code behind fil this.send_button.ServerClick += new System.EventHandler(this.send_ok);
So here is the problem when javscript returns true its not firing the serverclick event.
when i click on the textbox which is inside the item template of gridview then onclick event should fire and then call the javascript function but my problem is that there no onclick event option in item template's textbox

How to fire the event?
I have developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
my problem is here, when the user clicks the parent node, I need to fire a javascript onclick function before the server side event(SelectedNodeChanged) called..
If I provide javascript to the parnet node when it is binding, then I could not fire the server side event(SelectedNodeChanged).
How to provide onclick javascript event for parent node in treeview control even the parent node has SelectedNodeChanged event.
I want to add javascript onclick event on each page number in datagrid paging.
View 5 RepliesI've got problem with generating ajax anchors. I'm using simple
Ajax.ActionLink("test", "Test", new AjaxOptions { UpdateTargetId="test", HttpMethod="GET" }) and the generated markup is:
<a data-ajax="true" data-ajax-method="GET" data-ajax-mode="replace" data-ajax-update="#test" href="/Home/Test">test</a>
which, obviously lacks the onclick="Sys.Mvc.AsyncHyperlink.handleClick(...)" attribute.
well i have already created the rows and cells dynamically using asp.net table control ...but how to add an onclick event on that ...so that i could retrieve the corresponding cell when a particular row is clicked ...if it was a html control ,i could have used javascript but in this particular case m unable to find any solution..

View 2 RepliesIs there a way to add a Html.ActionLink through javascript? For instance, I have this Edit function in my controller:
public ViewResult Edit(int companyID)
{
....
}
And I'd like to do something like this in javascript:
var id = $("#hdnID").val();
$("#editLink").html(<%: Html.ActionLink("Edit", "Edit", new { id }) %>);
A bit of a crude example, but it's basically what I'd like to do. Is it at all possible?
I would like to update the content of a div using the result from an action method which returns a PartialView. The below code would do just this.
<%= Ajax.ActionLink("Update", "Comments", new { id = 1 }, new AjaxOptions { UpdateTargetId = "divComments" })%>
<div id="divComments" />
public ActionResult Comments(string id)
{
...
return View(photo.Comments);
}
Is it possible to have this update occur from inside a javascript method rather than from a link on the page?
I know that I do not want to actually use an Ajax.ActionLink from within a JavaScript function, but for the life of me I cannot figure out how to replicate the behavior. Here is what I have in my MVC 3 RC2 _Layout.cshtml:
[Code]....
I do NOT want to use:
[Code]....
Unless that can be made to populate at runtime, on demand from a script. manually clicking the ""Load Menu" ActionLink works exactly like I want except it requires the user to click the link; I want to do that for them... in this case from the Body onload event.
When I edit single recored in page, I use checkbox to get a selected row not every row with an actionlink element, but it seemed I cant make this way happen through calling javascript code(function GetSelectedRow() should return an id). Could anyone have a nice idea?

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 Replieshave 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?
View 4 RepliesI am having a treeview with nodes of products populated on first time through xmlresponse.Onselectednodechanged event, I have performed xmlseriaization to build a request to get list of subproducts. Now, my issue is how do I handle the next On_click event requesting for items under subproducts which will inturn calls the same onselectednodechanged method and how do I write condition to skip above steps to occur, since I need to build a different request on click of subproducts asking for items.
