Web Forms :: How To Handle OnClick Event
Apr 29, 2010
I 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.

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.

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)

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 am trying to define an event on a listbox to allow users to click on a specific item and do processing on the event. I've tried the obvious OnClick and OnSelectedIndexChange events which are not part of the listbox collection of events.

I have an XML file that contains a list of training videos that our site offers. I'm using a DevExpress control called DataView and within the ItemTemplate I bind all the appropriate information. However, I have an ImageButton that I bind a downloadVideo(string fileName) function to the OnClick event. When I click on the image the function does not fire though. Can anyone see what I'm doing wrong?

When I view the source of the page the OnClick event reads OnClick=downloadVideo(fileName.mp4) .

I am having trouble with two buttons on a page. I dragged them on to the page and then double- clicked each of them in order to create the OnClick events.
I added my code to the events, but when I click the buttons, their respective events aren't being called.

I have a button that I cannot see or click in design view in VS but I can locate it in my source. The reason I cannot see it is because it is overshadowed by a panel that has a repeater in it. I am trying to create an onclick event for it. The way I normally do this is just double click on the button or click on it and click the small lightning bolt in properties and double click the Click event for the button. This time I cannot do that.
So, I tried to create an on click event by doing this:
<asp:button ID="btnAdd" OnClick="btnAdd_Click" runat="server"/>
I then went to my .cs file and created a tidbit of code like:
protected void btnAdd_Click(object sender, EventArgs e)
{
lstEfins.Items.Add(txtEFINrehang.Text);
txtEFINrehang.Text = "";
}
However my button does not work... Its a very simple objective for my button, just adding a textbox value to a lstBox and I know its correct, so I know my code isnt broken. I just cannot get that button to fire correctly.

I'm having problems with trying to get a string into a onclick event on an input button. Ill paste my code and explain more...
[Code]....
But i cant do that as the code is in an aspx page, not an aspx.cs page. I tried doing it this way...
[Code]....
But for some reason, when i try it that way, the page refreshes after the button is clicked and it messes up the layout of my page.

- 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.

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;
