More often programmers need to work with dropdownlist or combobox using jquery. We need to manipulate the dropdownlist options using jquery scripting. And it is the case that almost always we don't remember how to implement jquery selector. And for all of my readers, who are enthusiastic programmers and/or designers, and for myself, I am discussing in this post the actions with jquery to manipulate asp.net dropdownlist options. read more...

Disable button in asp net web page to prevent multiple clicks(dotnetspidor.blogspot.com)

submitted by sangam100(357) 4 months, 14 days ago

When a user clicks a button and the response is slow, there are chances that user may click the button again. The scenario may occur both when the button postbacks synchronously or asynchronously. This type of multiple clicks could be prevented if we could just disable the button just after the first click and enable it again when the processing is done. This is quite easy to implement the task in both the cases: synchronous and asynchronous postbacks... Read More>> read more...

Frequent question on parent and child page refresh, reload etc.(dotnetspidor.blogspot.com)

submitted by sangam100(357) 6 months, 1 day ago

You can partially change parts of the parent page 3. You can control the behaviour of parent page from its child (even from iframe child page)... read more...

Refresh parent page partially from iframe without reloading the iframe(dotnetspidor.blogspot.com)

submitted by sangam100(357) 6 months, 24 days ago

Programmers using iframe to load another asp.net web page often need to only partially refresh the parent page so that iframe keeps itself from reloading. This can by done by calling the parent page javascript function from the child page loaded in the iframe. This way we can even avoid the need of ajax to refresh the parent page without affecting the iframe content. read more...

Refresh parent page from child window in asp.net with javascript(dotnetspidor.blogspot.com)

submitted by sangam100(357) 6 months, 26 days ago

Much often we open child windows from parent web page. In the child page we perform some activities, and later close the window. At the very time we may need to refresh the parent page so that changes made in the child window be reflected in the parent window. We can easily accomplish this using javascript in asp.net web page. Let me show the way using code snippets. read more...

Toggle image using jquery for animated hide show in asp-net (dotnetspidor.blogspot.com)

submitted by sangam100(357) 2 years, 1 month ago

Web masters find it attractive to mark or indicate some text in a page as special part. For example a featured product in a shopping cart would hold a finished featured icon image at its side. Similarly we see New image icon blinking at the side of some product or text. It is sometimes better by far to use such animated images to draw user's attention. How would you do this using jquery? The simple answer is that- toggle the image based on its display status, in a regular interval. read more...

Prevent page postback on enter key press in textbox in asp-net web pag(dotnetspidor.blogspot.com)

submitted by sangam100(357) 2 years, 2 months ago

In an asp.net web page, you may have experienced that pressing enter key postbacks the page. For example, take the following scenario: In the page, if you press enter key in any of the textboxes, the page will postback, which is not desired. What’s the reason? Lets look at the html markup generated for the page: The asp.net button control has been rendered with “submit” type, which is the reason of page postback when enter key is pressed in any of the textboxes. read more...

jQuery Mutually exclusive checkboxes in asp.net (dotnetspidor.blogspot.com)

submitted by sangam100(357) 2 years, 3 months ago

We often see radio buttons to implement single choices out of many in web forms. Wouldn’t it be better if we could imply ‘choose one option from many’ using checkboxes? I have implemented such mutually exclusive checkboxes in asp.net using jquery. This certainly is not any new practice. We have already seen such mutually exclusive checkboxes in asp.net ajax, and perhaps there are others also. But achieving this functionality using a lightweight javascript library like jquery would be a benefit. So let’s start the race. read more...

Hi all. There has been little lagging in my presence to you all with new post. Actually these days there are lots of things in my mind. I am looking over the web to know the best asp.net performance practices. But most of the times I do get stuck with the same old strategies you can find everywhere if you search with the keyword – "asp.net performance tips" or so. However, these tips work 90% of the cases, they are intermediate ones. What about the advanced ones? There are some genius guys who have presented advanced and deep asp.net performance improvement techniques, and thanks to them. Good things cannot hide, so you are sure to find them over the web hanging here and there, no problem. To give example: this one from codeproject and this one discussed in asp.net tutorial. read more...
