ASP.NET/JavaScript - I'm Trying To Get An ImageButton OnClick Event To Swap Images.
Jun 29, 2010
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 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.

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)

ASP.NET says that the following ImageButton server tag is not well formed:
<asp:TableCell VerticalAlign="Top">
<asp:ImageButton runat="server" ID="imgAdd" src="Images/add_plus_1.gif"
onmouseout="this.src='Images/add_plus_1.gif'"[code]....
I think all the mouse event attributes are legit, so I don't know what it's complaining about.

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 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 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.

Why isn't the image displayed? The folder images is in the same folder as the .aspx file.Why doesn't it invoke the ImageButton1_Click method when I click on the image? The OnClick should be for the server side.The ImageButton1_Click method takes 2 parameters, but why OnClick does not require 2 parameters?
<asp:ImageButton
ID="ImageButton1"
runat="server"
ImageUrl="images/export.gif"
OnClick="ImageButton1_Click"
/>
protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
Label1.Text = "You've clicked the image button.";
}
I have to add this line to the Page_Load method in order for it to invoke the ImageButton1_Click method when I click on the image, why?
ImageButton1.Attributes.Add("onclick",
"ImageButton1_Click()");
This line works fine too:
ImageButton1.Attributes.Add("onclick",
"ImageButton1_Click('report.xls', GridView1)");
The 2 parameters are: object sender, ImageClickEventArgs e. What are they and why I pass in a string and a gridview, which I don't think match with the arguments definition, and it still works?

If I use an ImageButton or LinkButton, I just noticed that when clicking either, the Page_Load method executes before the method specified in the OnClick. Can this be avoided so that the method in the OnClick is triggered instead of Page_Load?
