View 2 Repliesive imagebuttons which created in runtime from database and i need to add them onclick or mouseover event but i failed imagebutton.click += new ImageClickEventHandler(imageButton_Click); im adding this when i created imagebuttons, what i need else also i tried javascript but its not firing too;
<script type="text/javascript">
function SetProductImage(imgID) {
document.getElementById('imgProduct').src=document.getElementById(imgID).src;
}
</script>
imgProductImage.Attributes["onclick"] = "javascript:SetProductImage('" + imgProductImage.ID + "')";
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)
what're the differences between onclick event and oncommand event?
View 2 RepliesI've inherited an ASP.NET project that has poorly designed HTML; in one section, the tags are wrapped with an tag to allow for "click the row to view the information" functionality. The code is:
<asp:LinkButton ID="ViewArticle" runat="server" CommandName="Navigate" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "id") %>' >
<tr runat="server" class="list_item">
<td>some data</td>
<td>some data</td>
<td>some data</td>.........
How do I go about tying a JavaScript "onclick" event to the codebehind?
I am using the following code to load user control on to ASPX Page, which under a Master Page:
[Code]....
The user control name is passed as a parameter on the URL.
Inside the user, there is a LinkButton. The link button has a simple server side code for OnClick event.
Everything is working fine on the production machine, but, on the Development machine, I can see incorrect behaviour. I have started making some development changes on the Development Machine since several months back, and it will be very difficult to find out what caused the problem.
When I click the LinkButton inside the user control, the user control is removed from the parent page, and the OnClick event of the LinkButton is not firing.
I did debug, and found out that after I click on the LinkButton inside the user control, then the Page Load events for the master page and the ASPX page are working fine, and the IsPostBack is set to true, but the OnClick event of the LinkButton is not firing.

I have a simple form with a button. The button is server control.
in the OnClientclick event of the button control, I am actually doing some validations. If the validation fails, the onclick event should not be executed. How can I control this?
In the code below, PerformChecks() function gets fired first and alert message pops up fine. But immediately onclick event (which is handled on the server) gets triggered. if the check in PerformChecks fail, how can I suppress onclick event?
Code:
<asp:Button ID="ButtonRun" runat="server" Text="Go"
onclick="ButtonRun_Click" OnClientClick="PerformChecks();" Width="57px" />
function PerformChecks() {
var checkboxCollection = document.getElementById('<%=CheckBoxListInstruments.ClientID %>').getElementsByTagName('input');

I have a modalpopup extender attached to a button. That is to say the button is the targetcontrol id of the modalpopupsxtender. I would still like the onclick event of that button to work because only the onclient click event is working. How can i go about this.
View 1 RepliesI have a question connected with controls and event handling. Lets say I want to create a LinkButton.
protected void loadLinkButton()
{
ContentPlaceHolder content = (ContentPlaceHolder)this.Master.FindControl("MainContent");
LinkButton lnk = new LinkButton();
lnk.ID = "lnikBtn";
lnk.Text = "LinkButton";
lnk.Click += new System.EventHandler(lnk_Click);
content.Controls.Add(lnk);
}
Here is the event handler:
protected void lnk_Click(object sender, EventArgs e)
{
Label1.Text = "ok!";
}
If I run the loadLinkButton function inside Page_Load everything is ok. But when I try to run the loadLinkButton by clicking simple button, link button is created but event is not handled.
protected void Button1_Click(object sender, EventArgs e)
{
loadLinkButton();
}
I there any way to solve it? Or loadLinkButton must always regenerated on Page_Load, Page_init etc.
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 have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:
[Code]....
Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.
I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.

View 3 RepliesI 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 have a problem with some part of an applcation am developing, i have a button that works the first time its clicked and then does not work after that. There is a visible page post back, but the code is not executed. I want the a label on a page get a new value whenever the button is clicked.
Sub Button_Next_Click(ByVal sender As Object, ByVal e As System.EventArgs) x = Integer.Parse(Label_previous.Text) x = x + 1 Label_previous.Text = x End Sub
<asp:Button ID="Button_Next" runat="server" Text="1" Width="65px" onclick="Button_Next_Click" />
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.
