  • Need Sharepoint like modal pop-up window

    - by Srikanth
    I need to show Sharepoint 2010 like pop-up window when clicked on a link in grid view. Once the modal pop-up displayed and user selected the Save button data base should be updated with given values in pop-up. How can I get this. Any Idea. As of now I am using below code to get it but no idea how to pass the values to Database once clicked on the button in pop-up Note: As of now I am not adding the gridview code here as I wanted to achieve it first with sample html then wanted to do with grid view. Java Script function openDialog() { var options = { html: divModalDialogContent, // ID of the HTML tag // or HTML content to be displayed in modal dialog width: 600, height: 300, title: "My First Modal Dialog", dialogReturnValueCallback: dialogCallbackMethod, // custom callback function allowMaximize: true, showClose: true }; SP.UI.ModalDialog.showModalDialog(options); } //Results displayed if 'OK' or 'Cancel' button is clicked if the html content has 'OK' and 'Cancel' buttons function onDialogClose(dialogResult, returnValue) { if (dialogResult == SP.UI.DialogResult.OK) { alert('Ok!'); } if (dialogResult == SP.UI.DialogResult.cancel) { alert('Cancel'); } } // Custom callback function after the dialog is closed function dialogCallbackMethod() { alert('Callback method of modal dialog!'); } HTML <div id="divModalDialogContent"> Hello World! <input type="button" value="OK"onclick="SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.OK, 'Ok clicked'); return false;" class="ms-ButtonHeightWidth" /> <input type="button" value="Cancel"onclick="SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.cancel, 'Cancel clicked'); return false;" class="ms-ButtonHeightWidth" /> <asp:Button runat="server" ID="btnClicked" Text="Clicked" onclick="btnClicked_Click" /> <input type="button" value="Open" onclick="openDialog()" /> How can I call db upon clicking 'clicked' button in pop-up. Also I need to send parameters to pop-up Thanks in advance

  • How can I use removeFromSuperView and dismissModalViewControllerAnimated at same time ?

    - by srikanth rongali
    I have a UIViewController *view1 and another UIViewController *view2; I used presentModelViewController to navigate from view1 to view2. -(void)function:(id)sender { NSLog(@"The libraryFunction entered"); LibraryController *libraryController = [[LibraryController alloc]init]; [self presentModalViewController:libraryController animated:YES]; } I have another view UITableViewController *tableView; I added it to view2 as a subView. -(void)viewDidLoad { RootViewController *rootViewController = [[RootViewController alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController]; self.navController = aNavigationController; [aNavigationController release]; [rootViewController release]; navController.view.frame = CGRectMake(0, 0, 320, 460); [self.view addSubview:navController.view]; } In RootViewController.m I have - (void)viewDidLoad { [super viewDidLoad]; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)]; } -(void)close:(id)sender { [self.view removeFromSuperview]; [self dismissModalViewControllerAnimated:YES]; } WhenI touch close button I need to return the view1. So, I removed the tableView by using removeFromSuperView. But, I am not able to get to the first view. I do not get where to use - (void)dismissModalViewControllerAnimated:(BOOL)animated; to navigate to first view1 where I have started ? How can I do this ? Thank You.

  • moviePlayBackDidFinish: is not called in application.

    - by srikanth rongali
    In my application I have used these notifications when playing a video. But, The problem is the control of the program is not entering in to the first two methods(moviePreLoadDidFinish and moviePlayBackDidFinish). It is entering into last method. So, after the video is played and I pressed Done button in the video, I cannot touch any object in screen. I mean I used play button for video to play in a view. After the video played the play button is deactivated. - (void) moviePreloadDidFinish:(NSNotification*)notification { } // Notification called when the movie finished playing. - (void) moviePlayBackDidFinish:(NSNotification*)notification { } // Notification called when the movie scaling mode has changed. - (void) movieScalingModeDidChange:(NSNotification*)notification { } I could not get where I was wrong ? Thank You.

  • how can stop creating duplicates in camera roll while using UISaveVideoAtPathToSavedPhotosAlbum to s

    - by srikanth rongali
    I have a video in applications documents folder. I need it to be saved in camera roll. So, I used UISaveVideoAtPathToSavedPhotosAlbum method to save it in camera roll. It's working and I can see the video added to camera roll. But, the problem is every time I execute the application with same video(with same file name), it is added another time in camera roll instead of replacing the old one. So, it is creating the duplicates of the video. How can I make the application work like if a video is present in camera roll and again added with same file name, then old one is replaced by new video.

  • When we should use pushScene and replaceScene in cocos2d ?

    - by srikanth rongali
    Hi, I cocos2d, I am using pushScene and replaceScene to move to next scene. But, I am confused which we should use? When I am using replaceScene in some places app is crashing and giving errors like -[UITextView length]: unrecognized selector sent to instance 0x842a750 Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UITextView length]: unrecognized selector sent to instance 0x842a750' But, in my program I am not passing length to UITextView. My program is in this way In scene1 I have UITextView, and I am replacing this scene with scene2. Then -(id)buttonPressed:(id)sender { [description removeFromSuperview]; // It is the textView(description) CCScene *Scene = [CCScene node]; CCLayer *Layer = [scene2 node]; [Scene addChild:Layer]; [[CCDirector sharedDirector] setAnimationInterval:1.0/60]; [[CCDirector sharedDirector] replaceScene: Scene]; } But, when I am using pushScene in presence of replaceScene it is working good. Please clarify me which one should use in which cases ? Thank You

  • Cocos2D: Problem Rotating a CCMenu

    If I try to do actions over menuItems but the actions are not running as expected. I think code below should make the menuItem rotate by 90 degrees but when I run it, the menuItem translates from its coordinates to another coordinate then returns to its original coordinate. The complete translation takes 3 seconds. What I need is for the menuItem to rotate by 90 degrees in place within a 3 seconds duration. Please explain where I have done wrong?

  • How to set probability for a targetSprite shooting accuracy in shooting game ?

    - by srikanth rongali
    Hi, My code is ion cocos2D. I have written code for generating the bullets from the enemy gun for every 0.3seconds. The enemySprite is in right side of the screen in (land scape mode) at winSize.height/2. the bullet starts from the same point and reach the player's end. I used rand() to generate y-coordinate for the bullet to hit on player side. Now, if the bullet bounded rectangle meets the player bounded rectangle the enemy won. If it misses enemy shoots again after 0.3 seconds. Every thing is fine up to here for me. But I have 10 enemies and each have accuracy of hitting player of probabilities ranging from 0.80 to 1.0. First enemy probability is .80 and 10 enemy's is 1.0. How can I adjust the probability for enemy such that it runs according to its probability. Player also hits the enemy.
