AJAX :: Modal Popup Controls Values Are Duplicating?
Jul 12, 2010
I've used modal popups before with no issues, but now I am getting a strange issue I need help with.I'm using .net 4.0, this is my first new project using it, so perhaps it is something to do with that.
I've setup a modal popup which contains textboxes and a dropdownlist to insert and update values in a database. The popup displays correctly, and the code behind works perfectly to insert new rows into a database and update existing ones. My problem is, it's inserting and updating 'incorrect values'. If I type "test123" into the textbox and save it, the value "test123,test123" is saved. I do not have any code that does this, and i think it is the modal popup extender, because when I move controls out of the modal popup panel and onto the main page (inside an update panel) they are no longer affected by 'duplicating' string values and "test123" is saved. ",<duplicateValue>" is appended after EVERY post back. I've had the textbox displaying "test123,test123,test,123,test123" after a few save button clicks. Is there anything blatantly obvious to check (viewstate or something similar) that will correct this behaviour? I promise I'm not duplicating the values myself, they only seem to duplicate after the submit button click inside the modal popup panel.

I wish to find out what was entered in the textbox when the button is clicked I try this but the value of ((TextBox)button1.Page.FindControl("theTitle")) is null.
if (((TextBox)button1.Page.FindControl("theTitle")).Text == "")
void okButton_Click(object sender, EventArgs e)
{
try
{
//if i try this tt does not compile//The name 'theTitle' does not exist in the current context//if(theTitle.Text == "")//{//}
Button button1 = (Button)sender;
//TextBox theTitle = ((ImageButton)(e.Item.FindControl("theTitle")));
if (((TextBox)button1.Page.FindControl("theTitle")).Text == "")
{
}
else
{
}
}
catch (Exception)

I have three modal popup and three link buttons the first link button is on menu i.e. login that shows login-popup and the login popup contains two links forgot password and register both of them opens a popup but the problem is the login popup isnt hiding with click on register or foreget link the popups are appearing perfectly but arent hiding.
The html for all three popup is as shown below:-
<cc1:ModalPopupExtender ID="Modallogin" runat="server" PopupControlID="loginpanel" TargetControlID="loginlink" BackgroundCssClass="modalBackground"
CancelControlID="lnkforgot">
</cc1:ModalPopupExtender>
<asp:Panel ID="loginpanel" runat="server" CssClass="modalPopup">
[Code] .....
And the codebehind file that i wrote some code which also isnt working is as shown below:-
protected void Button2_Click(object sender, EventArgs e) {
Modalforget.Hide();
} protected void lnkregister_Click(object sender, EventArgs e) {
Modallogin.Hide();
Modalregister.Show();
[Code] ....
I also used breakpoints on link click event and are not going to code behind file on click and popup is just shown without hiding the other. And the css used is I found on aspsnippet site!

Modal Popup user control (its a message box) on top of a modal popup with javascript that maintains postback on a scrollable div all inside of an update panel causes my page to flash on postback of the user control. If any one of the peices (user control, modal popup, javascript) are missing everything works fine. The javascript is maintaing scrollback on a scrollable listview on the page. A modalpopup is shown on top of this main page that is for report parameters. The user control is used for validation and is displayed if a parameter is invalid. I know this may not be the best design, but it can't really change unless its a minor change. Heres the js if anyone wants to see popup or styles let me know.
//Begin methods to maintain or reset scroll position during postback.
var controlIds = [];
var scrollTops = [];
//Register a control to maintain its scroll position on postbacks.
function MaintainPostback(controlId) {
controlIds.push(controlId);
}
//Find the div/control id in the controlIds array and set its scroll position to 0.
function ResetControlScrollTop(controlId) {
var index = 0;
while (index < controlIds.length) {
if (controlId == controlIds[index]) {
scrollTops[index] = 0;
return;
}
index++;
}
}............

I look for a good way for arrangement Admin pages Items
for example Admin Upload Page consists of these sections:
* make a new folder
* delete folder
* upload file in folder
* show folders information (in a gridview)
* download test
so I think one way is showing this sections in modal
but when I tried make a new folder in modal after clicking in create folder button modal disappeared.
Is there any way that modal doesnt disappear until user click close button?
I mean I want modal to behave like a page.
If there isn't a way what to do for classification sections?

I'm using modal popup extender and panel with calendar in it. Click the "Next / Previous Month" closes the modal popup. How do I tell the modal popup to ignore click events in a calendar control inside the panel targeted for popup? I'm confused because when using extender before, you had to click OkButton or Cancel to close popup. I have update panel for reason. I just minimized the code for easy review.

I have one page with a panel that makes up my ModalPopup. On the ModalPopup there is an updatepanel with a textbox and a button in it. There is a textbox on the "parent" page and I want to click the button on the modalpopup and move the data from the popup textbox to the parent textbox. So far, no joy. I have a line in the code behind to move the data between textboxes and I have also tried javascript to do the same thing but I am not able to make this happen unless i click the button twice.

I there a way to dynamically add controls to a Modal popup?
What I want to do is put a modal popup container on the bottom of my pages .... then based upon the user action (say button click) I want to populate the modal popup with all the necessary controls for that action (ie. textbox, select list, user control,etc.). One button may be just a modal popup with a textbox and button, another might be a select list with button.

How can I get one modal popup to trigger a second modal? And in between each modal, I need to execute server code.
Page load, check if question needs answering -> Modal 1 -> User answers -> run server code to check if question two needs answering -> Modal 2 -> show page.
I could do this using a series of asp:Views if there is not a clean way, the management just really likes the modals

I am looking for sample code where a button click on the server side will spawn a modal child page, having couple of controls such as textboxes and a button, where one could enter values in the text boxes and click the button; once the button is clicked, the page should postback to the parent page, where the entered values could be read. There is a video on this site about AJAX control kits describing modal popup, but unfortunately it wouldn't serve my purpose.

I saw guide on here [URL] ....
Which I found useful to create gridview with dropdown filter. What my gridview differs from your one is based on ID, a modal is loaded. E.g. there is a column called "review" and in that column there is image that when clicked it loads a modal with details. My question is, how do i do this using the code provided by you. So ID is passed back to code. (So backend knows which row is clicked).

When using a modal popup extender along with an embedded video, the popup is hidden behind the video in IE but works as expected in FF.I've tried manually setting the z-index of the popup to a huge number and the z-index of the video object to 1 but this makes no difference.
I've put the code for a sample page below.
