Web Forms :: Text Box - Filter Data In Text Changed Event

Aug 11, 2010

I have a list box with data coming from the database. Above the list box I have a text box. If the user enters some text in the text box,then the data in the list box should be filtered as per the content entered in the textbox. In my page, i have about 7-8 such similar textboxes and listboxes. So I want to implement a common function which can be used for all the text boxes in the page. I tried to achieve this in textchanged event and javascript but sometimes not working. Is there any other simple way except javascript? Is it efficient to use java script in this scenario? Need your valuable inputs.

Forms Data Controls :: Cannot Repopulate / Filter Datagrid With User Entered Value From Text Box

Feb 18, 2011

I have a Datagrid control which is populated with data from an Access database when the page loads - a simple 'Select *' command. This page also contains a text box and a button, the idea being that the user can then filter the data by entering a value in the text box and clicking on the button to pass the new parameter to the datasource.

However, I cannot get this to work, I know it has something to do with 'IsPostback', but I am at a loss. I have tried variations of the following in the code behind page but to no avail.

Web Forms :: Universal Text Filter For Postback?

I'm creating a small, private social networking site. I wanted to add 'emoticons' by filtering text such as and replacing it with an image tag. That's easy enough with stringname.Replace() but what i'm wondering is, is there a way to add some sort of a 'filter' that will automatically do that replacement for me on ANY string post back so i don't have to add the replace code to every page?

Web Forms :: 3.5 Events - Is Supposed To Fire On The Client Side When Text Is Changed

May 27, 2010

I'm new to ASP.net 3.5 and testing functionality before developing an asp.net web site. I created a page with a formview. I added several text boxes. I created an event on the FirstName_TextChanged event and added a stop in the sub. When I open the page in the browser and type in some text in the FirstName and press tab, nothing seems to fire.

1) Is this supposed to fire on the client side when text is changed?
2) If so, would the vb.net code entered work like Javascript code on the server?
3) If so again, is it possible to update another textbox based on the text entered into the FirstName on the Client Side (would do this in Javascript in Classic ASP)?

I think I'm totally confused. I've been searching web for article about how to do this.

Forms Data Controls :: Text Change Event Should Not Fire?

Dec 29, 2010

Kindly, see the following image. This is my Gridview with separate paging on the top right of the image. The arrows are Image buttons and the right text box is read only.[URL]

I run my page for the first time everything runs perfect. I move to other pages of the grid still perfect. Then i move to other aspx page and then come back. The page loads perfect with the old page number there still perfect. Now if i press any image button then the text change event fires which should not fire.

Note: i need the text change event as i user randomly enters something in the text box then i have to handle that.

Example:

When i return from the other aspx page then the value in the Page Number text box is lets say 4. Then i press the Back image button and a post back happens. The Value in Text box is still the same 4. Then y the event is firing ???

I am not understanding that why this event is firing. On the page load, i retrieve the values from hash table (The hash table is stored in session in base page) and from the hash table i get the pageNo and assign it to the page No text box.

Here, is my one of the image button event. (Remaining image button events are almost same)

My text box change event.

My page load Code: Note: PageUniqueIdr = PageUniqueId retrieved from the QueryString.
