I have form with a HTML.DropDownList and a HTML.SubmitButton. I would like to validate item selected in dropdownlist once there is a click in submitbutton. Any ideas?
I have checkboxes in one column of listview and outside the listview I have one dropdown and one button.
when I dont check any checkboxes in listview fire a validation "Select any one checkbox" on button click.
simirarly when I check Checkboxes in listview and I'm leaving to select dropdown fire a validation"Select any item in the dropdownlist" on button click.
how to validate both controls(checkboxes in listview and dropdown) when those are not selecting.
I have 1 drop down, 1 text field and 1 command button i.e. "Search". Dropdown contrains following values
Type1 Type2 Type3
In textbox user will enter numeric or alphanumeric value
Here I want to check if 'Type1' is selected so user can enter only numeric value between 1000 and 2000, otherwise display some message "Entered value is not valid for "Type1". I want to display this message thru required validator error message property
If user select 'Type1' and 'Type2' then user can enter any alphanumeric value other than 1000-2000 numeric range.
I want to implement thru Search button or once user leave the textbox after entering value. Here I want to display message.
if txtQuantity is a positive Number I must enter something in txtDesc
So
I can't submit the form without entering txtDesc if txtQuantity is positive/decimal number & No need to enter anything in txtDesc if the txtQuantity is 0/null/empty/space/spaces/blank How?
With the HTML helper, how would you enforce number only without submitting? I know it was done with regular expression if you had a textbox in classic ASP.NET

i have a calendar control whose value will be displayed in a textbox, i need to validate the textbox value to the current date... It should not be less than current date.....
I have a textbox called "tax rate" which I need to validate the input... The only thing I need to ensure is that the value entered is a number (decimals ok of course). eg. the input might be "8.75" How do I write the validation expression?
I have tried everything and can't seem to wrap my head around it...I am trying to use the RegularExpressionValidator to validate that a asp:textbox has an '' in the value that the user types in, and it can't be the first or last character.
I have a drop down list and a textbox on a form. If a user select employee in the dropdown box, I wish to add employee email addresses in the text box. It should do the same if users select client on the drop down (i. e. Add client addresses in the textbox). I have not been able to do it without having to click on a button.
I'm developing an an asp.net 2 application in c#. This site is being built with accessibility in mind, and as such I need a to build a registration from that validates using server side scripts and not use client side validation.I need to validate a textbox (whether any text has been entered), if a check box has been checked.
Bear in mind that I can't use any clientside code such as javascript postback that is wired into the <asp:CheckBox /> control.
how am I be able to validate multiple entries (textbox control). It seems that using custom validate is not possible because each validator has one control to validate. In my case, I have to determine if at least one entry was filled with data.
I have 3 text box's and a submit button when i enter the values and submit then values are entered in database but when i enter the same values and enter then those values are also entered.......This should not happen...I need a popup window showing there are duplicate values that you have entered.Please give the code for aspx and aspx.cs and data base.
I have a textbox that I am "custom" validating to lookup in a table to see if the name exists. When I test it out, if it finds a duplicate, the validation results in an error message as I would expect. First is this only works if I add autopostback to my textbox and that I click elsewhere on the page. The other issue is that after I type a string in my textbox, I want it to validate such that if it returns an error, I don't want to submit the form until the validation is good.

I'm trying to create a simple user registration page. I'm using an MS Access database which has some test data in it. What I would like to do is use a CustomValidator on the user name textbox to check if the user name entered already exists in the database. I've read about the possibility of using the ServerValidate event for the CustomValidator control but I can't figure out how to make a connection to the database, query it to check the existing user names, and then fire off the CustomValidator if the user name exists.
