Web Forms :: How To Validate The Length Of The Text Present In The Textboxes Of A Gridview Using Javascript
Apr 6, 2010
Can any one let me know "How to validate the length of the text present in the textboxes of a Gridview using javascript".
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 am working on asp.net, for example in a form they are 10 text boxes i want to validate each textbox if it is empty it should display a alert message.
how to achieve this by using a single javasript method. can we pass texbox as an argument into javascript how to achieve this

I have a two-character field for US State. I add a RegularExpressionValidator control to validate the input using
ValidationExpression="[a-zA-Z]{2}"which works to validate the content when something's entered, but it doesn't catch if someone just leaves the textbox blank.
Is there any way to validate within the same regex to catch an empty textbox?
I have an ASP.NET gridview where I allow the user to edit a record. I need to validate multiple fields as one. I need to require that the user either enter a first and last name OR a company name. All three cannot be blank. Most of the sample code I am finding does not address the text boxes only being visible while the gridview is in edit mode. When not in edit mode, the text boxes do not exist so document.getElementById('<%= editFirstName.ClientID %>') throws an error upon page load.
I am trying to add a validation of the textbox.text.length in a FormView and prevent the insertion of being made in case the text length is not compliant (less than four characters).
In the scenario when clicking the submit button an Alert should appear with xxxx warinig text. and the Insert command being prevented.
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 two textboxes on the same page with their corresponding buttons to enter the data and both the textboxes require validation.
The problem is that if any of the two buttons is clicked it causes client side validation. What I want is only corresponding button shud cause validation.
I'm looking to validate the length of a textarea using a regular expression validator. It should allow all characters and crlfs. I'm also concerned about crlfs counting as 1 or 2 characters, I'm concerned it may be different across browsers but I'm hoping ASP.NET regulates it. Also, I'm saving to a mix of varchar and nvarchar fields in MSSQL, do I need to be concerned about the way crlfs are saved there? I'm in a hurry to do this right, so I'll be researching all this on my own but I'm just hoping someone out there might have experience handling such concerns.

My user filled a textbox with a text that was copied from Microsoft Word. This is a part of the text .
This system is - AUTOMATIC - and it is restricted

This system is â€" AUTOMATIC â€" and it is restricted

Whatz wrong with my this code ? I wanna validate two checkbox using if statement ... on Button click
When the box is checked, I want to display the length of Textbox1's value. The problem I encounter with the code below is that it gives error about object not found. It cannot find TextBox1 object. I try to replace document.forms[0].TextBox1.value.length with MainContent_TextBox1.value.length or with document.getElementById("TextBox1").value.length or with document.getElementById('<%= TextBox1.ClientID %>').value.length but none of those works. They all give the same error about Textbox1 object.
