I have a gridview that is binded with my datasource. I have 2 template columns in my gridview, out of which one is readyonly. Both the texboxes may or may not be filled with data from the db. What I want is when the user enters some values in the textbox, then on blur of that textbox that value is multiplied by 5 and entered into the texbox next to it. Or basically I want to handle the onblur event of the texbox in a gridview.
View 4 RepliesI have a web form where i have a key field "Account #" and ive put some live validations sort of function which validates the input text against values in database and instantly displays result if the account # is valid or invalid and ive put this on "onblur" event of the textbox.
The problem i am facing is that i have a "SAVE" button also and when user inputs account number the onblur fires and validates the input then user presses tab key fill other details and change his mind and go back to account # and type some invalid values and without pressing tab clicks on SAVE button with the mouse ..darn in this case it doesnt fire ONBLUR instead if fires SAVE event...how to overcome this problem and execute onblur first in any case.

I'm here again to share a problem that I'm fighting against for days. I'm developing an eCommerce Cart.
Within it, I have a repeater, inside of ITEMTEMPLATE I put one TextBox for product quantities and one Button, for update the quantity inserted on that textbox.
When the customer clicks over the Button, it fires a function that gets the content of the TextBox and do an update on my Database.
It works perfetly when it is done with the mouse click. But I need to fires the update function WHITHOUT the manually click event. When the customer just put the mouse out of the TextBox (onblur event), I want to fires that function.

I need to attach a function to the onBlur event of a textbox column in my gridview. I know how to attach the event but I need calculating the total.
I have a TemplateField with a textbox as the ItemTemplate and Three labels in the FooterTemplate for Sub Total, VAT and Total.
So when I enter new values into the textboxes I want the totals to get calculated automatically as the textbox loses focus.

I have TextBox1 (enabled = true) and TextBox2 (enabled = false) in my WebForm on loading. Both are validated by means of a RegularExpressionValidator.
How can I set TextBox2 enabled = true ONLY AFTER (!) the text inserted in TextBox1 has been validated and accepted as valid ?
Can this be done on client side exclusively or is some code behind absolutely necessary ?
I have a text for user inputs Date. There is a CompareValidator which is used to compare Date between 2 TextBoxes. User do not need to input separator. After finish inputting value, he presses Tab to call a Javascript function to Format value of this Textbox.
Ex : user inputs
TextBox1 (From) : 01012010 =>Press TAB =>Value : 01/01/2010.
TextBox2 (To) : 01022010 =>Press TAB =>Value : 01/02/2010.
But Compare Validator show Error after cursor leaves the TextBox2. If I choose these values from Date Picker => No problem.
I think Compare Validator is called before onblur event. Is that right?
If it is right, is there any way to do my work?
how to validate
1.TextBox should not accept the DateFormat
2.Should not accept only numbers
3.it's accept combination of numbers and alaphabets.

I have a project due for my Visual Basic course. The project is creating a web application. I'm setting up the application where the user will enter information in a textbox. I want to be able to test the value entered in the textbox. There are three test conditions - less than a certain number, between a range of numbers, and greater than a certain number. I'm familiar with Visual Basic but not that with Visual Web Developer. I want to display a message to the user that tells them the value entered is low, normal, or high, and display additional information. The question I have is can I attach three validation controls to a single textbox? I know how to attach one validator control, and that works fine. I try to attach three controls but when I run the program all three error messages display, which is not what I want. I think I would need to code a custom validator but not sure how to do that.
