A user inserts ad details and on button click saves them to database. If the save is successful, a DIV element slides down (becomes visible) allowing the users to add pictures for that ad.
As the users adds the pictures, they are being shown in a Repeater control. When you hover over a picture, a Delete button is displayed and when you click it, a confirmation message pops out asking the users if they really want to delete the picture.
Now this is where the problems begins. The code behind the button click doesn't wait for the user to click YES or NO. It just executes leaving the message displayed.
So to summarize:
- The entire "bottomDIV" element is wrapped inside an UpdatePanel with update mode set to "Conditional".
- Since the Button is inside the Repeater control, I cannot access its Click event. I use Repeaters ItemCommand to check for the correct Command Name.
- The Repeater Control is inside the same UpdatePanel
- The Update Panel has AsyncPostBackTrigger set to Repeater Control.
The HTML:
HTML Code:
<asp:UpdatePanel ID ="bottomUpdate" runat ="server" UpdateMode="Conditional" >
<ContentTemplate>
<div id ="bottomWraper">
<div id ="savePictureWraper" runat ="server" style="float:left; padding-top:3px;" >
<asp:TextBox ID ="pictureName" runat ="server" placeholder ="Naziv slike" style="width:181px;">

The Script (using alertify.js to display the confirmation dialog):
HTML Code:
<script>
$("[id*=btnDeletePicture]").on("click", function () {
alertify.confirm("Confirm?", function (e) {
if (e) {
alertify.alert("Successful AJAX after OK");
[Code] ....
The code behind is simple and all it does it executes the delete statement and then calls the displayPictures sub again. So, why the code behind doesn't wait for the user to select an option in confirmation dialog....
I want to show a confirmation dialog when a specific value is selected in an asp:DropDownList. If the confirmation dialog returns false (cancel) then I want to prevent the AutoPostBack.
I need to collect additional information from the user when they initiate a delete on a radgrid. Right now I am presenting the user with a confirmation dialog box that lets them click "OK" to continue but I need to add an additional textbox to collect a reason.
I want to confirm from the user before deleting a record. I want to show a message box to confirm operation... How I do that.. I used query to delete a record on button's click event..
I have JQuery confirmation dialog function that called by server side code (C#)how to get its return value of that function? in this case the return value would be either Yes or No.I called it in button clicked event as below:
Code: protected void btn1_Click(object sender, EventArgs e) { string message = "Message from server side, please select yes or no"; ClientScript.RegisterStartupScript(this.GetType(), "Popup", "ShowConfirmation('" + message + "');", true); }
my question is how to get JQuery return value, in this case the return value would be Yes or No?
I am trying to use confirmation dialog from jQuery UI.
I ran into this problem: how to trigger correctly the dialog and at the same time prevent trigger OnClick event specified at button until user click on Yes or No buttons at dialog?
In the example below are two ways how to popup confirmation. Lower one works well. It's a classic JavaScript confirm dialog. When I try to use the jQuery UI dialog, it displays a dialog but allows it to run the event assigned at OnClick (here by using Command, but I suppose there is no difference. Hope I am not wrong.). The piece is taken from the ASP.NET Repeater control btw.
Is there any way to add a confirmation dialog to a submit button when the form already has other validation controls and a summary control using "showmessagebox=true"? I tried adding
OnClientClick="return confirm('Are you sure?');" to the submit button, but that seems to block all of the other validation?
I am having a gridview with some button column. I have written some functionality in code behind for the button click. How can i display a confirm dialog in mid of the button click functionality and based on users response(Yes or No from dialog) i need to continue the remaining funtionality in the button click event.
An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.
I basically want to show a dialog box with confirm or cancel options on it.
Confirm should allow the partial postback to take place, cancel should not. I have tried using a trigger and calling __doPostBack() as advised here but it posts back the full page not just the panel.
$('#buttonInUpdatePanel').live('click', function (event) { event.preventDefault(); var item = this; var title = 'Confirm'; var msg = 'Please confirm something'; var $dialog = $("<div id='myDialog'></div>") .html(msg) .dialog({ modal: true, buttons: { "Confirm": function () { $(this).dialog("close"); __doPostBack('Button1', null); //tried this and .submit() on the button //return true; }, "Cancel": function () { $(this).dialog("close"); //return false; } }, title: title }); });
I have changed the doPostBack to use the button ID now and commented out the return true and false lines. When I click the button it calls the confirmation dialog but when you click on confirm it appears to do nothing. I was expecting a call to the method AddExtraVehicle_Click but the breakpoint didn't trigger.
I load an aspx page in iframe inside a jQuery UI dialog to update some data, and after dialog is closed I need to update an updatepanel in parent page. how can I do that? to be more specific, there is a datagrid in parent page and after I edit data in a dialog modal iframe, I want to update the row in datagrid.
I am using MVC2 on VS2010 Express edition. I followed a post by Dino Esposito on UI with JQuery passing data to a dialog from strongly typed views. I can't make the dialog work with modal:true option.Here I have a simple page that includes RenderPartial for a dialog. The dialog is supposed to pop up when a button is clicked. However, if I include modal:true as one of the dialog options, then when the button is clicked nothing happens. The dialog does not pop up. When I remove modal:true from the dialog options then dialog pops up as expected and closed as expected.
I've got a div on Page A.When an event happens (whatever I define, a click, whatever), I do a div.Dialog, set its properties and open itThe data inside is returned from an async .ajax call that grabs the data from a url and appends it to the div by calling div.html(data) inside the .ajax callback, so it's essentially loading a PageB by getting the data (content) and appending it to the div that's calling the dialog("open")...nothing special here I don't think.
My question: In Page B, how do I reference the dialog so I can do some things to it? For instance in Page B's content that I received back from that .ajax call and added to the div via .html(data), there is a button and when clicked I need to close the dialog.Right now my buttons are not working inside the dialog because one of them closes out the dialog and the other should redirect to a new page but both do not work now because I have no reference to the dialog that it's in to manipulate it. So I need reference so I can close the dialog via some jQuery that will reside in PageB (data).
I need to create below layout using Div's. i should not use table to create this. also i need to do this with css and I have to use % for width and height. Any sample code. on the below image left border is missing. But I want that as well.

This code works fine for populating a div with html from a view. Where I'm having trouble is figuring out how to pass a string parameter to my view, so as to customize what the view returns. Passing a number doesn't seem to be a problem, but I can't get the string right. I need to know:
1. how to format the string in the url - or even if passing the string in url is right. 2. how to structure the route in routeConfig.
I have a gridview on a page where I display a list of items. One of the columns on the gridview is a hyperlink that sends a querystring to another page, which then displays the details of the selected item. It's your basic CRUD operation and it works great except for one thing: The query string has some information in it that I'd rather not be public. Is it possible to have a link or a button or some other sort of column that does a post to the new page instead of a querystring?
I need to produce a simple graphic which is a simple rectangle (bar) with a variable portion filled in to denote a percentage.
What is the best way to achieve this? I had a look at the .net charting tools but the nearest I could find to what I needed was the barchart which didn't quite seem to meet my needs for a single value.
I have a gridview that has 3 dropdowns. And when I am in edit mode, when updating via the RowUpdating event, I am not getting a value from my 2nd or 3rd drop downlists. Here's the code from RowUpdating:
Code: Protected Sub gridOutdoor_RowUpdating(ByVal sender As Object, ByVal e As GridViewUpdateEventArgs) 'WHEN DEBBUGING, the text for ddBodyColor.Text is an empty string. I had selected a value prior to this event firing." Dim ddBodyColor As DropDownList = DirectCast(gridOutdoor.Rows(e.RowIndex).FindControl("ddBodyColor"), DropDownList) End Sub
I have a form and I want to insert the current time at which the user clicks to insert into the table of my db. When running, I get the following error when trying to insert into my sqldatasource:
"System.FormatException: String was not recognized as a valid DateTime."
I have created a single checkbox in the DetailsView of my Asp page. I then created VB code behind to set the value =1 if the checkbox is checked and value =0 if checkbox is not checked. I cannot get the code to work. The record will get created in my SQL database, but the checkbox field remains NULL
In SQL table, my field and datatype is: Greenfield, bit, NULL
And the VB code behind. I originally used OnCheckedChanged but that wasnt working and it was suggested of me to use DetailsView1_ItemInserting instead: (The Dropdownlists in the code are working)
Code: Protected Sub DetailsView1_ItemInserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewInsertEventArgs) Handles DetailsView1.ItemInserting Dim DropDownList6 As DropDownList = CType(DetailsView1.FindControl("DropDownList6"), DropDownList) Dim DropDownlist9 As DropDownList = CType(DetailsView1.FindControl("DropDownList9"), DropDownList)
