Web Forms :: TextBox: OnTextChanging / User Is Clearing The Text, If The Length Of Text Becomes Zero?
Jul 20, 2010
I have a page with a text box, a button and a GridView. Enter an account number in the text box, press the check button and the result will show in the GridView.
Now user wants that if the text box is clear, the GridView disappear.
I can only find TextBox1_OnTextChanged. But I want to have that while the user is clearing the text, if the length of text becomes zero, the GridView is clear out. So I am looking for OnTextChanging(). Well of course this function does not exist. How to achieve the same purpose?
I have a scenario whereby I have a textbox with an autocomplete extender attached and two drop down lists; this enables a user to search for product info. Ideally I'd like to create something that effectivley, 'resets' the drop downs so that when a user clicks on the textbox (maybe I'll do it 'onenter'/'ondelete' if there is such a thing). I've had a look at .Attributes.Add but cannae figure it out. How do you include asp.net controls within this scenario so I could have something along the lines of:
I have a ddl that controls the visibility of a textbox (using panels). For example if i select 'Other' from the text box, a post back occurs and a text box appears beneath it for you to give further details. If any other value (for example 'dry') is selectedit's an accepted value and nothing else happens. Only problem is that if i select other, add details the text box and then go back and change the value to 'dry' (for example) the text box may dissapear but the value is still held within the box
I have an asp page with a textboxes, labels and other controls. I cannot get the .text to change in any of these controls. I click on button which I execute code that I expect to update the text but it doesn't work. Something like Textbox1.text = "Hello" Are there page level properties/settings I should look at? I am perplexed an looking for a place to start. I will provide more information as needed. I just don't know where to start.
I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.
For Example: In a page I am displaying a Gridview with textboxes inside it and a button on the page. The user need to input some text in the textboxes of the gridview and click on "Submit" button. When the user clicks on Submit Button, we need to validate the length of the text present in the textboxes of the gridview. If the length of the text inside the textbox of the gridview is less than 10 , we need to throw an error message. In the same way we need to do validation for each and every textbox inside the gridview.
I have an ASP.Net UpdatePanel that updates on a timer. Within the UpdatePanel and nested in a GridView, I have a TextBox that the user enters a value in with a submit button. Everything works fine, except if the user does not submit the value before the timed interval, the text is removed from the TextBox. Is there a way to persist the user entry into the TextBox between updates? Is there a better way of doing this?
I want label to display limited text say 20 char even the data it retrieve from database may be more than 20 char.. like in gmail,we see message body limited when we click it display whole message..how is that possible...?
I was wondering if people out there test the length of their text values before inserting them into an SQL INSERT or UPDATE command? I got lazy and stopped doing it lately but I do restrict the length of some of my character fields so that I have a NCHAR(50) field but don't test the length of the string when inserting or updating and just rely on the server to fire back any problems.Am I being 'efficient' or 'lazy' or even 'dangerous'?I appreciate the opinion of you as just about anyone has more experience with SQL Server than I do.
in my application (asp.net) i have a filed ( phone code) and it contain a text box. and i want to restrict the user to enter only 4 letter after that the cursor should not print any character how can i write the code
I am using CreateUserWizard control on my admin page.After successfully creating a user with the control, it displays "Complete Your account has been successfully created."After clicking on continue button it sets the ActiveStepIndex Correctly.The problem is, while it sets the ActiveStepIndex correctly, it retains the old user account credentials.
im using gridview to read data from datasuorce(my access) and im editing data using 'enable editing' from smart tag(in design window .aspx), now i want to change the edit text: edit(i hav named it as edit) to 'view' for one particular user whose name:'sunil'?
this is my table(in my access layer and calling this data through datasource of gridview):
Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene
