Web Forms :: ImageButton OnClick - Get Information?
Sep 18, 2010
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?
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?
and I want when I click on linkbutton it doesn't open new window...
here when I click on linkbutton it doesn't open new window it is correct but when I click on imagebutton and it opens new window and back to page and click on linkbutton it open linkbutton in new window...
I want when I click on link button it doesn't open new window any way...
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
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?
ive 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;
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:
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)
I am making an online form (literal form) that needs to have a certain function: when the user enters a 5-digit number, the form should automatically query the MS SQL DB and retrieve information associated to that number and populate other form elements (text boxes, etc.) accordingly.
So say the # was 12345 and in the DB, the record matching 12345 has name=Fred. So, when I enter 12345 into the form textbox, the name text box should be automatically populated with Fred in it.
If this is not easily achievable, I guess a submit button beside the 5-digit number text box can do.
I am still learning my way around ASP.NET and Visual Studio 2005, however I have ample experience with HTML, CSS, JavaScript, C/C++. The ASP.NET app is to be written in C#.
I have a multiview, with constant back and next imagebuttons, that are positioned and characterized by an external css style sheet. One of my views however are of different widths from the others so this view needs to have the buttons positioned accordingly. I am trying to do this in my pagebehind VB.NET code with Visual Studio 2008 3.5, of assigned similar Imagebutton.CssClass = "~/css/classname" where classname is the name of the class I wish to set dynamically to the buttons.
Public Sub FwdDetermineMultiView() If mvAddReferral.ActiveViewIndex = 0 Then BuildReferralInfo() mvAddReferral.ActiveViewIndex = 1 ibtnPersonalInfoBack.Visible = True ElseIf mvAddReferral.ActiveViewIndex = 1 Then BuildContactInfo() mvAddReferral.ActiveViewIndex = 2 ibtnPersonalInfoBack.CssClass = "~/css/mvPanelNavbtnLeft1245" ElseIf mvAddReferral.ActiveViewIndex = 2 Then ICategories.CategoryList = CountChecks(lbCategories) If atLeastOneRowSelected() = True Then ICategories.Category = GetCategoryNames(ICategories.CategoryList) Session("Categories") = ICategories mvAddReferral.ActiveViewIndex = 3 Else MsgBox("You must assign at least one category", MsgBoxStyle.Exclamation, Wrn) mvAddReferral.ActiveViewIndex = 2 End If ElseIf mvAddReferral.ActiveViewIndex = 3 Then Response.Redirect("~/aacess/Referral/ReferralSummary.aspx?") End If End Sub
I am trying to find out what html is generated when a control is rendered. For most controls, the following worked fine: Dim tempbuilder As New System.Text.StringBuilder() Dim tempwriter As New
System.Web.UI.HtmlTextWriter(New System.IO.StringWriter(tempbuilder)) Dim generatedhtml as String Me.imgImage.RenderControl(tempwriter) generatedhtml = tempbuilder.ToString()
However, when I tried doing it with an ImageButton, I recieved the following error: Control 'ctl00_cphExampleContent_imgButton' of type 'ImageButton' must be placed inside a form tag with runat=server. What can I do to avoid this?
I need to replicate the Web Forms ImageButton control in my MVC app and I have read about Html.SubmitImage. However, this helper method is not appearing in my list of options in Intellisense. Here is my code :
Is there a way to assign a byte[] as Image to a ImageButton?Currently i'm using the Aspx:BinaryImage which allows me to assign a byte[] as Image.Problem is that the BinaryImage does not support a onClick event.
I am using an Imagebutton to open a webpage. This code works but what I wonder is if it is possible to have a new browserwindow opened with yahoo.com instead of
I have a ImageButton on a master page and a text box. Basically I set the default button to my image button and in the master page I have the following code:-
Code: Protected Sub butSearch_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles butSearch.Click If txtSearch.Text <> "" Then Session("SearchFor") = txtSearch.Text Response.Redirect("~/Search.aspx", True) End If End Sub
When I click on a menu button which has its navigateurl set it works but if I select a different button which loads another content page it does not.
