Dec 29, 2010
i am working on a project.but i have a problem.basically,i am using ajaxtoolkit tabcontainer.assume that i have 2 tabs which i created.let's call them tab1,tab2.in tab1 there is a button and textbox.when i click the button,i am writing some text into the textbox. then i am creating a tab dynamically. assume that it is called "tab3".the problem is when i click the button in the tab1,tab3 is diappearing.how can i prevent this?
I am new to jQuery. i place the return false to stop postback, that postback is stopped, but error messages are appearing. How can disappear the message by click cancel button. I used e.preventDefault() also it not working. here my code:
I am trying to use wizard in an update panel but the wizard is disappearing when I click for the next or prev step button. I only want to close wizard , when I click the finish button. How can I do this ?
I am using Crystal Report on my ASP.NET Fw. 3.5 project. My report contains 100+ pages. When I click on next page button on crystal report viewer control my whole page gets postback to server and then second page appears. This take same time when first time report gets loaded.
My web form contains a postback button. The button will postback and call a server-side method. The method will process something that may spend about 20 seconds. However, user may try to click the button several times within the waiting period. The sequential clicking may cause the first running method incomplete and stop, since the second click postback will dominate the method and start again. How can I solve it?
PS: It can not use client side script to disable the button, because it requires to use some server-side validation within the method.
Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.
Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.
I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.
Example of Button Definition (within GetAdministrationInterface)
- 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?
I have a site that show infomation that are contained in div blocks. The info is taken from a database so the user can change the info or delete it. When the user deletes a div block i want to use jQuery to animate that its disappearing and also that its deleted from the database. How can i do this without doing a postback, i dont want the site to reload, i just want the Div block to disappear visually and be gone from the database at the same time. Would i use Ajax update panel to achieve this ?
Server Click event is not being triggered when I click on the "LookupButton". The weird part is that this code works on our Dev server, but not QA. If I get rid of "LookupValidationGroup", from the Lookup Button ValidationGroup property, the page does postback, but then my validators do not work. I could explicitly do the validation on the Server Side, but dont think I should need to.
No errors are being displayed. I also reinstalled .net 3.5 using aspnet_regiis -i command.
When I clicked Header area, Content opened and have "Slide effect". but when I clicked Header's "ImageButton", it do something at codebehidn, Content opened but no "Slide effect". I want slide effect, how to do it,
[aspx] <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <AjaxToolkit:Accordion ID="AccordionMenu" runat="server" SelectedIndex="0" HeaderCssClass="accordionHeader" ContentCssClass="accordionContent" AutoSize="None" FadeTransitions="true" Width="200px" SuppressHeaderPostbacks="false"> <Panes> <AjaxToolkit:AccordionPane ID="AccordionPane1" runat="server"> <Header>Pane 1 <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/images/expand.jpg" /> </Header> <Content> The Details of Item1. </Content> </AjaxToolkit:AccordionPane> <AjaxToolkit:AccordionPane ID="AccordionPane2" runat="server"> <Header>Pane 2 <asp:ImageButton ID="ImageButton2" runat="server" ImageUrl="~/images/expand.jpg" /> </Header> <Content> The Details of Item2. </Content> </AjaxToolkit:AccordionPane> </Panes> </AjaxToolkit:Accordion> <p></p> <asp:Label ID="Label1" runat="server" /> </ContentTemplate> </asp:UpdatePanel> [.vb] Protected Sub ImageButton1_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton1.Click Me.Label1.Text = "[Call Header Function 1]" End Sub Protected Sub ImageButton2_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton2.Click Me.Label1.Text = "[Call Header Function 2]" End Sub
when i click on button then postback happen but i stopped the postback. my code is follows.
[Code]....
here ShowDiv() function return false. another thing i notice that when i comment all the line in function ShowDiv() then postback is not happening. i just do not understand if i generate a div and add to page from javascript then why postback happening. tell me the solution to avoid postback when i will generate div from any function.
I dont know what happened but none of my buttons or linkbuttons causes a postback anymore. I have dragged a few updatepannels on the page but the linkbutton concerned is not enclosed within an update pannel. when I click it there is just no postback happening anymore. I set the debugger at Page_load but...its not reached. I used firebug to analyse the http requests. there is none. its like those are not considered buttons anymore.
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.
I am creating a button dynamically in my code and attaching a click event to it. However I have to prevent people to click it while there is a process going on. So when it is clicked once, it should be disabled and when the process ends it should be enabled. How can I do that?
what might cause the back button/history in Internet Explorer to become greyed out when navigation between web forms occurs?
Example - I have a hyperlink on my main webform that when clicked directs the user to a second web form. This web form has a variety of databinding occuring. When the page has finished loading/binding, the back button goes from blue to grey. It appears that the referring page is removed from the history as well.
I have page on which I've a login control in which I've a subnit button. The problem is this that when I refresh the that page the submit button or any button that was clicked last before page refresh gets its click event automatically fired.
I have an ASP .Net TreeView control that I am dynamically adding tree nodes to from my codebehind on Page_PreRender. The TreeView is populated nicely and the appropriate checkboxes are where they are expected to be. For each of these nodes the SelectAction=TreeNodeSelectAction.None. However, when accessing the TreeView CheckedNodes() collection in my codebehind after selecting a few nodes (checkboxes are selected) and clicking a submit button to post back to the server in the button click event, my CheckedNodes.count() = 0. I can not figure out why my CheckedNodes collection in the codebehind does not contain the nodes that I have checked from the GUI.
I'm reading an invoice dataset and building a html table with checkboxes and textboxes in it, and I put that code in a postback = false block, then i got a button and a literal. The button click will loop through the html table checkboxes to calculate a total and assign it to the literal and display it. I got everything working except one thing, every time i click the button, the html table refreshes and lost all the value in textboxes....even though I put the html building block in the postback = false block,it seems like it still won't preserve the values in the textboxes once there's a button click...Anybody knows a solution to that? I want the textboxes keep what values are there.
...I get an async postback when I click the 'Edit' button for a particular GridView row. This is what I want. In fact, I also get an async postback if I then click the 'Cancel' button for that GridView row which appears after having clicked the 'Edit' button.
However, if I instead click the 'Update' button that appears after having clicked the 'Edit' button, I get a full postback. I have tried almost every GridView EventName
I can find to add to the <Triggers></Triggers> section to get a click of the 'Update' button to result in an async postback, but with no luck.
What EventName should I use in the <Triggers></Triggers> section to get a GridView to do an async postback when clicking the 'Update' button for a particular row?
I have created a web form in which i have used user control there is link button on different link button user control loads . i have added dynamically webcontrol to that link button . they are loading properly but when i try to save data through one of user control on click of button the user control disapper from that place but when i put static user control to my page its working

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.
