Javascript - Unable To Bind Event With Link Button On User Control
Nov 3, 2010
There are two user controls, which are built dynamically.
In the first control, I am adding a link button, and trying to attach a click event on the same. But the event is not fired.
Actually the main goal is, when the link is clicked, based on which one is clicked, I need to show second control (the values on the new controls are based on the first controls link button that is clicked).
If I use javascript, I will need to use ActiveX or is there any other way to instantiate the second control using javascript
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
Here is what i am trying to do I have a multiview and two views in it so based on click event the link the views change
[code]....
apparently they are not firing on first try. The reason i am doing this is the two views have tables with different images to be used in building my menu.
What am i doing wrong? or why is the click event firing on second try?
i place the onClick event in asp buttons. but it is showing error like
Too many characters in character literal
my code is
<asp:Button ID="Button1" runat="server" Text="Button" onClick="alert('The button was clicked.');" />
actually my requirement is when i click on the button i want to display some message and when we press ok then it is redirect to another page is it possible
I have few textboxes on a page which are loaded dynamically on change of text in dropdownlist. The user enters values in these textboxes and clicks on a addnewitem button. In the code behind I want to capture the values entered in these textboxes. But I get the value as empty.
On Pageload mthd there is nothing which is referencing to createdynamiccontrols method.Then I have
[Code]....
Firstly i am getting object reference not set to an instance of an object when the createchildcontrols method is called the second time and also if I dont have the createdynamiccontrols method in additem click event, controls are no longer tehre...
I have a User Control with a multiple number of link buttons.
What I want to achieve is to change the Background colour of one of the link button control in the page load event of one of the pages. I am finding it difficult to access the link button in user control .
I have a user control, which is added to another user control. The nested user control is built up of a GridView, an image button and a link button. The nested user control is added to the outer control as a collection object based upon the results bound to the GridView.
The problem that I have is that my link button doesn't work. I click on it and the event doesn't fire. Even adding a break point was not reached. As the nested user control is added a number of times, I have set image button to have unique ids and also the link button. Whilst image button works correctly with its JavaScript. The link button needs to fire an event in the code behind, but despite all my efforts, I can't make it work. I am adding the link button to the control dynamically. Below is the relevant code that I am using:
I have Web page that uses LinkButton control inside Template Fields of Gridview.I am trying to work on LinkButton Click event and trying to preserve the Value of LinkButton that user click, and based on that value, i want to refresh tha page data.
I used CommandName and CommandArgument property of Linkbutton, but i can use that property only in GridView_RowCommand method by checking e.CommandName expression. But the problem with that Gridview_RowCommand event fire after all other page_load activity. So the value never used in the page_load event to refresh the data in all other control.I also tried to use OnClick Method, Session variable and Hidden variable. but when i run Response.Redirect method from Gridview_RowCommand, it clear all the Session and Hidden variable values. also tried (Response.Redirect(,false)) method but never got success.
I have a link button which is part of my user control. Further, the control is actually added to the control dynamically. Whilst, I can see the control, and is added to the page without any visible errors, but when I click on to fire an event which on that user control nothing happens. What is even more odd, if I add a break point to event, and then click in debug mode, I can't even reach the break point!
To try and resolve this, I have tried giving the link button ids, and ensured they unique, added override using OnInit and used the createchildcontrols method, but nothing seems to work!
i have a link button thats text value is populated from a dataset value retrieved from a database. When the user clicks on this link button I want to somehow capture the text value. The trick is the linkbutton is within a usercontrol, and I want to do the processing from the user controls parent. I am able to get the ID of the clicked linkbutton with the use of Request.Form["__EVENTTARGET"];, however i need the text value, in this case its a job number.
I may be able to do this via javascript with the OnClientClick;
When I do this I get a javascript error saying "M10725"(which is my job number being clicked) is ndefined. I dont know what this means. Do I somehow have to give the linkbutton being click a value?
I am using Linkbutton inside the Repeater Control to display the paging ........and m calling Page change event on client click ....m attaching u code that m using it work fine in some webform but somewhere it didn't go the page change method on clicking page no. .....
I generate in a foreach loop html links ("test which I add to a pre defined literal.ow can I add a void to the generated html link? I tried with runat server and onclick.. but does not work..Goal is to add by the onclick a pre defined void from a API.
Each time i click on Load text button, i change the value of hfType (hidden field) then do postback to server using UpdatePanel, then this is code behind
protected override void OnPreRender(EventArgs e) { string type = hftype.Value; switch (type) { case "text": plhControl.Controls.Add(LoadControl("~/thitai/test/text.ascx")); break; case "image": plhControl.Controls.Add(LoadControl("~/thitai/test/image.ascx")); break; default: plhControl.Controls.Add(LoadControl("~/thitai/test/text.ascx")); break; } base.OnPreRender(e); }
One of my webpages has an asp.net ListView control, with an insertitem template defined. I would like to allow the users of the page to enter data in a text field in the insertitem template, press the enter key, and trigger the insert event (which normally happens when you click the 'insert' button). I've tried simulating the button click event in javascript, but that doesn't seem to be working.
I have a User Control that has been added to the page dynamically. When I click a button on that user control:
The button_click event is NOT being raised The page posts back The user control is removed from the page
Here's the button-click event on my User Control:
Protected Sub btnAddAttribute_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddAttribute.Click Try Dim attrName As String = txtAddAttributeName.Text Dim attrValue As String = txtAddAttributeValue.Text 'ADD ATTRIBUTE TO ATTRIBUTE TABLE putSQLData("INSERT INTO OD_Attribute_Values (AttributeName, AttributeValue) VALUES('" & attrValue & "', '" & attrName & "'")...........
is it possible to disable right mouse button click event of a link button. i know to disable it in entire page..but i want to disble it for some controls only.
I have a user control that displays some database records when I first hit the page. When I click the submit button the page load event fires again, loading the user control again. Then the button click event fires inserting a new row in the database which is not shown on the page because the user control already did its stuff. If I could get the user control to do its stuff after the button click event I could then see the newly inserted row. I can do this by pulling the code out of the button click event and sticking it in the page load event. However, I think that would be bad code flow. How can I get the user control to do its stuff after the button click event has fired?
I have a aspx page, default.aspx, with an user control in it. Inside the user control (UC 1) there is a DataGrid. When the DataGrid is loading data with ItemDataBound, I need to dynamically load another user control (UC 2) for each row in the DataGrid. UC 2 has a Button ( BTN )with an eventhandler associated with it in code behind.
User control loading is fine, and the Button, BTN, is there. However, when I click the Button, the eventhandler is not reached, not firing, even though the page does postback. I googled for this issues, and I know the dynamically loaded user controls need to be loaded every time the page is postback. In my case, it needs to be loaded each time the datagrid is doing ItemDataBound. I did it and even hook up the eventhandler with button click event each time when the user control is dynamically loaded. I set EnableViewState to true on the Page and controls.
The following is part of the code from UC 1, AcctPaymentDetail is UC 2 in the code.
I am fairly new to the asp.net and experimenting with it to learn the page life cycle. Here is a problem that I have been unable to resolve for past few days.
I have a hosting page (.aspx). Then I have two user controls (.ascx). The page has a place holder control in which it loads the user controls one at a time based on the application flow. First user control is loaded on application start up. It has a "continue" button. Continue button click loads the Second user control that has two buttons - "Back" and "Submit". Obviously the "Back" button should load the first user control again and Submit button should submit the form data. Pretty simple.
The problem is that the command button event handler that I have on the second user control is not firing the first time. (I have one event handler for both buttons). The load event of the user control fires but then it ignores the button click. If I click it again, then it fires. I re-load the controls on the page in every page_load. Here is some relevent code:
AddPlayer.aspx:
[Code]....
The page_Load fires every time but "CommandBtn_Click" doesn't fire after the first click. I have to do it click it again. It doesn't matter which order I click the buttons.
I have a blank user control (child) and during Page_Load i create some text boxes and a button. I also add an event to the button.
I then load that user control dynamically from a placeholder in another usercontrol (parent). Both controls are rendered correctly but when i click on the button, the event isnt fired. how to handle the event?
Child code:
[code].....
If i use the child control directy (ie without the parent the control) the click event is raised and handled nicely. But when i use the parent control, the debugger wont even hit a breakpoint inside UpdateButton_Click().
