How do I stop ModalPopup from closing

Posted By:      Posted Date: September 01, 2010    Points: 0   Category :ASP.Net
I have a simple example of a ModalPopup with a panel that appears in the center of the ModalPopup and a couple of buttons in that panel. One of the buttons is a cancel and the other is an OK button. No matter how many other buttons that I add each one closes the ModalPopup. I need to keep the ModalPopup open so that I can run a few calculations then click a close button.  Any help is appreciated.

Javascript Alert after closing a modalpopup

If the username doesnot exists  i want to show an alert 'Usename doesnot ' exists. 

Since the checking for the existenance of the username is on click of the button submit which is inside the modal popup, i can show the alert using the code

Closing ModalPopup from an embedded iframe


I want to put an iframe inside of a ModalPopup and then have a button click on a button inside the iframe trigger the close of the ModalPopup.  I am guessing this is possible by simply attaching a function to the onclick event of the button in the iframe that navigates the DOM to call a javascript function in the parent that ultimately closes the ModalPopup.  Now the targetId of my ModalPopup is a div, so I could see hiding the div manually to "close" the ModalPopup, but I was wondering if there are already functions built into the scriptlib for the ModalPopup that will allow me to open or show and close or hide it?  If so, how do I access those functions client side?  Are they documented anywhere?


Thanks in advance!

Data Security: Stop SQL Injection Attacks Before They Stop You


To execute a SQL injection attack, a hacker writes a Web page that captures text in a textbox to be used to execute a query against a database. The hacker enters a malformed SQL statement into the textbox that causes the back-end database to perform operations the owners did not intend it to perform, like making unauthorized updates. This article explains how you can protect against the all too common SQL injection attack in your own database. The steps covered include data validation, proper exception handing, and much more.

ModalPopup/UpdatePanel from codebehind, inconsistent behavior onClick


First post bear with me please:

I have a simple form with a list of linkbuttons, each fires the same onclick event which sets an indicator image.  I have a dummy button with style="display:none" which I have set as the TargetControlID of the modal.

onClick event from the imagebutton, the modal is shown via modal.Show().  The cancel button inside the modalpopup fires an event which turns off the indicator image and hides the modal via modal.Hide(). 

The events fire perfectly, it's very simple!  Although after doing some testing I noticed the modalpopup is not presented after the 6-10th cycle of clicking the open event, then clicking cancel.  The grey background appears but it is behind the main panel and the modal is either presented behind this or is just simply not displaying. 

I spent hours researching various methods, implemented the CancelControlID to see if it was somehow tied to my call of modal.Hide() that fails.

This occurs with an updatepanel only.  The behaviour is much cleaner this way, so I would hope to be able to implement this.  I have basically eliminated everything but these two events!  Please help

How to stop the repeated database queries for roles


Hello, friends,

We have a web application using VS 2008, c#. We try to filter siteMap nodes based on security roles. We have our customized the mether GetRolesForUser() in RoleProvider class to determine a user's role. In this method, roles will be returned by querying an SQL Server database.

However, we found that each time a page was loaded/refershed, this  GetRolesForUser() was called, and the database would be queried. This is too MUCH and expensive.

We thought the roles should be queried only once when a user logs in. After that, role info should be stored somewhere for this user, rather than query DB all the time.

Any ideas, reference paper, snipet,...,?

Thanks a lot!

How to stop unauthorized users from sending documents to a Records Center site?

The impossibility of doing things depends on your will to do it.

Check in dialogue does not show when closing word


In a document library that has check in and check out required a user on this network found that when they close word after editting a document, there isn't a dialogue asking whether a user wishes to check a document in.

This is how it normally works and without the dialogue there's all the likelyhood that many documents wont be checked in.

I did some testing and i found that the SharePoint drafts folder is located on a network drive. If i uncheck the box that says use local drafts folder on one of the dialogs that appear when openning a document then asks me if i want to check in the document when i close word, if i change the default location of the sharepoint drafts folder to a local folder then the dialog appears also. I can only assume there are some ACL's or File system atributes that tell word that the document needs to be checked in and those attributes are not read correctly if the document is on a network drive (perhaps ACL's are locked?).

You can change the default location with regedit or in one of the office programs so i was thinking that perhaps we could roll out a registry setting in the login script to default the sharepoint drafts folder to a local one, any other suggestions?

Refreshing a Jquery modal dialog after closing another Jquery modal dialog


I have one aspx page which contains a webpart. The structure of the webpart is:

Webpart(holds one user control say UC1)

      UC1-> contains another user control say (UC2) in a <div>, which I am going to show as a popup on clicking of a link button inside a gridview in UC1.

      UC2-> contain another user control say (UC3) in a <div>, which I am going to show as a popup on clicking of a button inside in UC2.

That means -> UC1(main page) ------->(Onclick) One JQuery popup(UC2)--------------->(OnClick) One Jquery popup(UC3) here UC2 is still remaining in focus and UC3 will be another Jquery popup on UC2.

Now my requirement is when i fill the Jquery popup(UC3) and click on save button in UC3, I would like to close UC3 Jquery popup and refresh the gridview inside UC2 Jquery popup without closing it.

Is this possible?(please explain the logic if found in terms of Jquery, but not in terms of normal popup windows)

How to stop blurring of barcode images

I have a custom DLL that has a function that takes a string and returns a raster image(PNG) of a Code 128 barcode. That works fine, no problem. The barcode rendered does *not* use a font, it physically renders rectangles with precise pixel widths to generate the barcode. This is necessary because the laser expects a discrete stop of a "bar" and beginning of a "space". -- Image properties->Size is set to "Original Size" So I look at the report viewer, and I see barcodes. Cool. HOWEVER ... when I zoom in at about 400% I start to see blurring at the edges of the bars. It also prints this way. This is unacceptable. So then, within report viewer, (this is the same report!) I export the report to PDF. No blurring, not at 500%, not at 2000% not at any zoom level. In the PDF, there is a sharp, precise, quantum drop from black to white with *no* blurring whatsoever. On pixel is 0x000000 and the next is 0xFFFFFF. The PDF also prints this way. This is correct behavior. I cannot have the user export the report to PDF before printing it. This is a production shop, and I can't have folks taking twice as long to do a task. MY QUESTION: How do I instruct, how do I force SSRS to simply render the image as I have presented it and not tinker with it? This is a bit annoying. If my function returns a 200x50 image, SSRS may trust that that is what is t
