I have a link like this
<a href="#thumb" id="ctl00_allContent_btnThumb" onclick="javascript:__doPostBack('ctl00$allContent$btnThumb','')"><img alt="" src="../../images/bullet-thumb.gif"></a>
On Firefox it does what it supposed to. But it won't work on IE or Chrome.I know there are some questions on the subject here, but they haven't helped me. I'm guessing it's more specific since it envolves ASP.NET postback.
I am trying to figure this up
[Code]....
So, as it may look i want to call MyFunction defined by me with the Id parameter of current object that repeater displays. This is obviously not working.
I would like to ask how can i make an html anchor (a element) or even any object to do a postback or to execute an server side method?I want to create a custom button (a wrapped with some divs to do some custom them) and i want to implement OnClick to be look like the ASP.NET LinkButton?Like<a href="#" onclick="RunServerSideMethod()">Just a simple link button</a>
View 3 RepliesI've added this code below to a MOSS 2007 web part inside OnPreRender() method.
if (!Page.ClientScript.IsClientScriptBlockRegistered("jump_to_anchor_JS"))
{
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "jump_to_anchor_JS", "window.location.hash="anchor";",true);
}
The page loads, jumps to the specific anchor, then jumps back to the top of the page. This has been tested in IE8, Firefox, Chrome, and Safari with same behavior.
I am trying to render a simple hyperlink that links to a named anchor within the page, for example:
<a href="#namedAnchor">scroll to down</a>
<a name="namedAnchor">down</a>
The problem is that when I use an ASP.NET control like asp:HyperLink or HtmlAnchor, the href="#namedAnchor" is rendered as href="controls/#namedAnchor" (where controls is the subdirectory where the user control containing the anchor is). Here is the code for the control, using two types of anchor controls, which both have the same problem:
[code]....
I am using the HtmlAnchor or HyperLink class because I want to make changes to other attributes in the code behind. I do not want to introduce a custom web control for this requirement, as the requirement I'm pursuing is not that important enough to justify abandoning the traditional ASP.NET link controls. It seems like I should be able to use the ASP.NET link controls to generate the desired link.
I am using a CSS button as
<a href="" class="btn green" title="Delete" OnServerClick="MyCodeBehindFunction">Delete </a>
Previously, I was using a button control instead of CSS button and using AJAX confirm extender before deleting. But how do I ask for this confirm action in < a href=""> now?
I have an ASP.NET Menu which generates many anchor tags when rendered.
My requirements were
to prevent postback if href or an anchor tag is "" or "#". to make the cursor not to show the hand First I checked the markup of one of the generated anchor tags
[code].....
When I hovered on the empty link, the cursor is showing the default one instead of hand, that means my anchor is recognized. But when I clicked the anchor, postback occurred!
Tried replacing anchor.unbind('click'); with anchor.kill('click');
Tried replacing e.preventDefault(); by appending e.stopPropogation and even return false;
Tried replacing anchor.bind('click', function(e){ with anchor.click(function(e) {
Nothing seems to work. What could be wrong with my code?
I know this topic has been posted before but I'm stuck on it still.I've placed creating of dynamic control on Page_Load but the event isn't firing.On my asp page, i have <asp:PlaceHolder ID="test" runat="server/>On my code behind, I have private display method.
private void DisplayButton() {
LinkButton btn = new LinkButton();
btn.ID="unit_1";
[code]...
- I've created a Survey with multiple sections in it
- The answer types are variable and, thus, the controls are created dynamically
- I have a Repeater where each RepeaterItem corresponds to a Category. (I have 5 categories in my current test, so I have 5 DataItems in the Repeater) Each RepeaterItem contains another Repeater which will hold the Question / Answer values
- After I data bind the Category Repeater, I loop through each RepeaterItem, find the Repeater contained in each RepeaterItem, and DataBind() this second Repeater to a list of Questions
- After DataBinding the Repeater containing the Questions, I sent that Repeater object to another routine, which is where the Answer controls are dynamically created and added to a Panel inside each of this Repeater's RepeaterItems.
I am able to navigate back-and-forth among Categories, save / delete answers, and fill in answers for Surveys that were left incomplete when a user logs back in.
One of the the potential control types for an answer is a ComboBoxList.
Each Question has an option for answers that require a ComboBoxList called "MaxAnswers." When this value > 0, I inject a little javascript that prevents the user from selecting more boxes than the "MaxAnswers" value. This is done during the last step described above like so:
[Code]....
This appears to always be added regardless of how many questions I answer or don't answer or how many times or directions I navigate around inside the survey. (I can push "Back" and "Previous" buttons as well as jump directly to any individual category by clicking a LinkButton)
Another option for Questions requiring a CheckBoxList is to specify if the selection of a specific ListItem within the CheckBoxList should display a TextBox. (e.g. a selection of "Other" will display a TextBox for the user to write-in an answer) I want to prevent a post-back just to show/hide a TextBox, so I inject an onclick event attached to the specific ListItem to accomplish this. The following code appears as the very next routine following the code pasted above:
[Code]....
This also works the first time the page is loaded but not after any PostBacks...
The lblMessage.Text lines are written to the page after ever PostBack, the MaxAnswers routine correctly adds the onclick event to the necessary CheckBoxList controls, but the "fncShowFTB" event is not added. Viewing the HTML with Firebug does show the onclick the first time the page is loaded, but it's missing after every subsequent postback.
Can anyone see what I am doing wrong that causes me to lose this event?
The Firebug HTML on initial page load looks like:
<input type="checkbox" onclick="fncShowFTB(this,'FTB50');" name="dnn$ctr556$View$rptCategoryPanels$ctl02$rptQuestions$ctl11$ctl00$6" id="dnn_ctr556_View_rptCategoryPanels_ctl02_rptQuestions_ctl11_ctl00_6">
After PostBacks, it looks exactly the same except that the onlick event is missing.

My guess is that it may releated to the ID's that are recreated.
I have used jQuery to invoke an AJAX webmethod in c#. This webmethod runs a query and stores the resulting information in a session variable. I have a gridview that has an objectdatasource that uses the session variable with the selectmethod to then populate the gridview with data from a query. I need the final piece to get the gridview to databind() again with the new value.
So click map, update gridview. However, maybe I'm going about this all wrong. In essence, take javascript variable, push to ASP.NET in C# and refresh gridview on page with new data from query.
I have created a user control which has a form and 2 buttons; Save and Submit. Both buttons are created at design time. Users can enter details in the form (e.g. title and description of an item) and click Save which does some server-side processing to create an 'Item' then clears the form.
The buttons:
[Code]....
[Code]....
And a placeholder to add dynamically created controls:
[Code]....
I am saving the Items in ViewState and dynamically creating a LinkButton control for each Item which allows the user to edit the item:
[Code]....
[Code]....
Now, when I test this in Visual Studio 2010, it works fine;
1. Enter Item title and description in form
2. Click Save
3. Save button triggers postback and onClick event code is run
4. ViewState list is displayed below the form
When I create a local IIS web site for testing, the postback on the Save button only works the first time I click it. Postback is false on the second click and the page reloads without running the onClick event code.
Novice question I guess:The Scenario.I have an asp.net page that contains 6 divs and 6 hyperlinks which are linked to javascript function:
function showdiv(divname)
{
hideallcontentdivs();
[code]....
the divs have id's: item1, item2....item6 and the hyperlink specify to the javascript function the id of the div that needs to displayed.
The Problem:Whenever I click on an hyperlink, the effect that I want is achieved but the page reloads too.
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.
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 server control button , btnProcessTransaction, which calls a method to run a stored procedure in the DB, I need to add another onclick to call a javaSCript funtion , how can i do both calls for the same button. Here is my code before applying the javaScript call>
<asp:Button ID="btnProcess" runat="server" Text="ProcessTrans" "
onclick="btnProcess_Click" />
Here is my code before applying the javaScript call>
<asp:Button ID="btnProcess" runat="server" Text="ProcessTrans" "
onclick="btnProcess_Click" onClick="CallJS('Demo()')" />
How many calls can I have in a single button?
I have 2 textboxes which has default values in forecolor:#999999. If I click on the textbox, the default value should clear and the forecolor should change to black. I mean, like watermarking. But I am not using any Ajax.
View 2 Repliesi am working in MVC & want to add a javascript file only in when the 'onclick' event is fired for actionlink... ie. by default a javascript file is not included in my project... but when the actionlink button is clicked then only the javascript file shud be added..
View 3 RepliesI'm trying to implement a onclick event to select an item in a asp:ListViewControl.
<ItemTemplate>
<tr runat="server" id="MemberRow" onclick='<%#ClientScript.GetPostBackClientHyperlink(LvMembers, string.Format("Select${0}", Container.DataItemIndex)) %>'>

However the onclick does not fire the ListView.Command or ListView.SelectedIndexChanging event? If I add a button with CommandName="Select" it works as expected? The POST data is the same!
{_EVENTTARGET=ctl00%24ContentPlaceHolder1%24LvMembers&_EVENTARGUMENT=Select%245&__VIEWSTATE=...}
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.

gridview radiobuttonlist onclick javascript?
So, I have a MasterPage, in which I have an ImageButton and an UpdatePanel. Inside the UpdatePanel I have a LinkButton.
[Code]....
As you can see, both components are asociated to the same OnClick event, which should open said PDF document in a new window using javascript (Code Behind of the MasterPage):
[Code]....
I build the path using the toolTip of the component that has been clicked,which has the name of the file that should load in the
new window.
When I run the application, and click the ImageButton, the new window opens and the file loads correctly. However, when I click the LinkButton, nothing happens (it should do exactly the same as the ImageButton).
If I set a breakpoint, and debug, when I click the LinkButton, it goes to the LnkRelease1 event (as it should), everything looks fine, but it doesnt open the new window, It doesn't execute the javascript window.open.
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
