I Have an aspx page that contains 2 buttons "Update" and "Default". I have a dropdown list which contains a few values, say 1 to 10. When I click on Default button, the dropdown is set to a default value, say 4. If I wish to set the dropdown value to 3, I choose 3 and click on Update button and the changes are saved somewhere, maybe a DB.
Initially, Update button is disabled. Only if any changes are made to the dropdown, the Update button is enabled. Assuming that the Update button is initially disabled, I click the Default button to set the dropdown to its initial value. When I do that, a postback happens during which the Update button suddenly becomes enabled and then disabled. How do I avoid this? During page refresh, I don't want the disabled Update button to become enabled and then disabled. ALl this happens in a millisecond but its still visible.
is there any way out of this?
Design code is as follows:

Since the button has no type defined, the default type is used which is a submit button.
This means that when you click the Default button, the JS code is running but then the form is submitted.
To avoid the submission simply make the button be ordinary button:
<button type="button" class="formEditBtn" onclick="javascript:setDefaults();" causesvalidation="false">Default</button>
Following is the line in setDefaults() method that enables the update button for a while, a post back occurs and update button again disabled.
document.getElementById("btnUpdate").disabled = false;
Either comment this line or set it to true

I have looked at a number of solutions to my basic issue, but have not found any solution that I either understand or that would work.
I have a page that takes in two items of information, filename and a store. The user then clicks on a button to execute a function that will update a database and send back a resulting string that I want to display on a textbox on the main form.
However, when they press the button I call a modalpopupextender using an UpdatePanel panel. That gets a value into the modalpopup. If the user validates that the correct store is selected they click an 'okay' button which then call the dbprocessing function that returns a result. The page is small so I'll give the complete aspx and c# code.
The function doProcess() returns a List of values which I convert to String for display. I left the session variables in for that was my last attempt at trying to get this to work.
Where I am confused is that when the first button on the main form (Process) is clicked, there is a postback which obviously hits the page load before the button click. That is when I display the popup. Then when the user clicks on the button Okay, another postback is perform hitting page load before the button click and in that second button I originally tried to set the textbox on the main page because there is no other action after the second click, but no data displayed.
What is strange, if I repeat the process, when I click to display the popup, my data displays. This is not making sense.
This is the aspx page

If I don't misunderstand your request your problem is caused by the postbacks. I think you can handle better your logic with jquery. For example you can use jquery to close the popup without performing postback:
$('#lBtnVerifyRequestClose').click(function (event) {
event.preventDefault();
$('#pnlVerifyRequestPopup').dialog('close');
});
the event.preventDefault() ensure that postback are not executed.
If you need server logic to put data on your popup you can bind a jquery function to the dialog on open event and retrieve there data / perform your logic. In this way your form will be submitted to the server only once at the end of the process.
I have a working AjaxToolKit SlideShowExtender in my ASP.net C# website, using Visual Studio Community 2015. The displayed images have varying aspect ratios (width/height) so that most of them are distorted because Image Height and Width are fixed. I am looking for a way of displaying the images without distortion, and without having to edit each image manually before feeding it to the SlideShowExtender. For example, could the Height and Width properties of the Target Image Control be tweaked just before display? If it needs to be done in JavaScript, I would need code help as I have managed to do everything so far just on the server side, and I know very little JavaScript.
Code added upon request
Selected files follow. SlideShowExtender is defined in SlideShow.aspx.

The solution is incredibly simple: Simply remove the Height attribute of asp:Image ID="Image1" in file SlideShow.aspx. The image's aspect ratio will be preserved automatically. Alternatively, one could keep the Height attribute and remove the Width attribute. I could kick myself for not running into this earlier.
I have tabs that open and close panels. Multiple tabs/panels can be open at a time. Followed is my current solution:
protected static int[] tabControls = { 0, 0 };
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
storyPanel.Visible = true;
hoursPanel.Visible = false;
}
}
/* ===== TAB CONTROLS ===== */
protected void Tab1_Click(object sender, EventArgs e)
{
if (tabControls[0] == 1)
{
storyPanel.Visible = true;
Tab1.CssClass = "Clicked";
tabControls[0] = 0;
ClientScript.RegisterStartupScript(this.GetType(), "hash", "location.hash = '#storyPostBack';", true);
}
else
{
storyPanel.Visible = false;
Tab1.CssClass = "Initial";
tabControls[0] = 1;
}
}
protected void Tab2_Click(object sender, EventArgs e)
{
if (tabControls[1] == 1)
{
hoursPanel.Visible = true;
Tab2.CssClass = "Clicked";
tabControls[1] = 0;
ClientScript.RegisterStartupScript(this.GetType(), "hash", "location.hash = '#hoursPostBack';", true);
}
else
{
hoursPanel.Visible = false;
Tab2.CssClass = "Initial";
tabControls[1] = 1;
ClientScript.RegisterStartupScript(this.GetType(), "hash", "location.hash = '#storyPostBack';", true);
}
}
Sometimes the tab needs to be pressed twice for it to respond and open the panel as well as receive the css changes to itself. I cant figure out why. Additionally, is there a better approach.
EDIT:
It's actually not tabs, sorry for not being clear. It's the illusion of tabs using buttons/panels/css:
Server controls:
<table width="80%" align="center">
<tr>
<td>
<asp:Button Text="Tab 1" BorderStyle="None" ID="Tab1" CssClass="Initial" runat="server"
OnClick="Tab1_Click" />
<asp:Button Text="Tab 2" BorderStyle="None" ID="Tab2" CssClass="Initial" runat="server"
OnClick="Tab2_Click" />
<asp:Panel ID="storyPanel" runat="server">
<table style="width: 100%; border-width: 1px; border-color: #666; border-style: solid">
<tr>
<td>
<h3>
<span>tab content here </span>
</h3>
</td>
</tr>
</table>
</asp:Panel>
<asp:Panel ID="hoursPanel" runat="server">
<table style="width: 100%; border-width: 1px; border-color: #666; border-style: solid">
<tr>
<td>
<h3>
tab 2 content here
</h3>
</td>
</tr>
</table>
</asp:Panel>
</table>
It looks to me like the initial state of all tabs is visible:
protected static int[] tabControls = { 0, 0 };
But in fact, only one tab would actually be visible right? Or are all the panels supposed to be visible at the same time? If your tabControls variable is out of sync with the actual visibility of the panels, it may require clicking twice. Once to change the tabControls to invisible, and then one to change it back to visible again. To fix, just do:
protected static int[] tabControls = { 0, 1 };

The problem is whenever I click "Next Meeting" nothing happens whereas it should set the label text to Next Available first or third wednesday of the month. It did worked before but since when I copied the whole code to a new website it is not working. What may be the problem?
That code has never worked correctly. Maybe it has worked seemingly before 18. Jul 2012 which was the third wednesday in this month, because then (Now < wed3) == true.
Now neither Now < wed1 nor Now < wed3 can be true which is the only way to change the label's text property.
if (Now < wed1)
{
Label5.Text = "The next meeting is on" + "\n" + wed1.ToShortDateString() + "\nat 7 pm in room S242";
}
else if (Now < wed3)
{
Label5.Text = "The next meeting is on" + "\n" + wed3.ToShortDateString() + "\nat 7 pm in room S242";
}
Maybe you need to tell us your real requirement. What should your program do?
You might also want to put the default settings in page_load in a if(!IsPostback) check, otherwise the Calendar.SelectedDate always is overwritten.
if(!Page.IsPostBack)
{
// not on postbacks, f.e. when the user selected a date
Calendar1.SelectedDate = DateTime.Today;
// ....
}
But one thing, if there's no First or Third Wednesday is available, it
should show the first wednesday of next month. Right?
That's the missing requirement i've asked for. Since the third wednesday is already in the past, you want to return the third wednesday of the nex month:
public static DateTime getNextWeekDay(DateTime date, DayOfWeek dayOfWeek, int weekNum)
{
if (weekNum < 1 || weekNum > 4)
throw new ArgumentException("Number of week must be between 1 and 4.", "weekNum");
int inWeekNum = date.Date.Day / 7;
if (inWeekNum >= weekNum)
{
var nextMonth = date.AddMonths(1);
date = new DateTime(nextMonth.Year, nextMonth.Month, 1);
}
DateTime currentDate = date;
int currentWeekNum = 0;
while (currentWeekNum < weekNum)
{
if (currentDate.DayOfWeek == dayOfWeek)
currentWeekNum++;
if (currentWeekNum == weekNum)
break;
else
currentDate = currentDate.AddDays(1);
}
return currentDate;
}
Yiou can use it this way:
DateTime wed1 = getNextWeekDay(Now, DayOfWeek.Wednesday, 1);
DateTime wed3 = getNextWeekDay(Now, DayOfWeek.Wednesday, 3);
You need a third case
DateTime getFirstWednesdayOfNextMonth(DateTime seedDate)
{
int year = seedDate.Year;
int month = seedDate.Month+1;
if (month > 12)
{
month = 1;
year = year + 1;
}
DateTime wed1 = new DateTime(year, month, 1);
while (wed1.DayOfWeek != DayOfWeek.Wednesday)
{
wed1 = wed1.AddDays(1);
}
return wed1;
}
and add an ending else to your Button3_Click
protected void Button3_Click(object sender, EventArgs e)
{
DateTime Now = DateTime.Today;
DateTime wed1 = getFirstWednesdayOfMonth(Now);
DateTime wed3 = getThirdWednesdayOfMonth(Now);
DateTime wedNext = getFirstWednesdayOfNextMonth(Now);
if (Now < wed1)
{
Label5.Text = "The next meeting is on" + "\n" + wed1.ToShortDateString() + "\nat 7 pm in room S242";
}
else if (Now < wed3)
{
Label5.Text = "The next meeting is on" + "\n" + wed3.ToShortDateString() + "\nat 7 pm in room S242";
}
else
{
Label5.Text = "The next meeting is on" + "\n" + wedNextMonth.ToShortDateString() + "\nat 7 pm in room S242";
}
}
By the way, when you know the first wednesday of the month, calculating the other two is simple a matter of adding 14 to the first one.
DateTime wed1 = getFirstWednesdayOfMonth(Now);
DateTime wed3 = wed.AddDays(14);
DateTime wedNext = wed3.AddDays(14);
// But it could be in the same month (1,8,15,22,29)
if(wedNext.Month == wed3.Month)
wedNext = wedNext.AddDays(7);
I am having Default.aspx Page for Login. After Successful Login it shows the ItemValuation.aspx Page but in the address bar the link shown is Default.aspx. The problem started after I implimented the jquery in my Project. If I remove the jquery
references and Code then link shown is correct after login i.e. ItemValuation.aspx
Can any one tell me how can I solve this Problem? After successful Login on Default.aspx the link shown in address bar should be ItemValuation.aspx For your reference I am posting the Default Page aspx code.
Thanks in Advance.

jQuery Mobile is the one that's doing that. By default, it changes all links and form submissions through AJAX.
To disable this... interesting... functionality, you need to add a handler to the mobileinit event, and set ajaxEnabled to false.
Docs here on how exactly to do this: http://jquerymobile.com/demos/1.1.0/docs/api/globalconfig.html
