Web Forms :: Range Validation To Allow Value Between Negative And Positive Number In TextBox
May 7, 2015
I want to put validation in a Textbox, that the numbers entered inside textbox should be between 1 to -1 only i.e., (-1, -0.1, -0.2, -0.3, -0.4, -0.5, -0.6, -0.7 ....... 1 )I tried below code but "RangeValidator" is not working as per requirement:
HTML:
<asp:RangeValidator ID="RangeValidator1" runat="server" MaximumValue="1" MinimumValue="-1" Text="value between 1 to -1" ErrorMessage="value between 1 to -1" ControlToValidate="TxtY" ValidationGroup="usrvalid"></asp:RangeValidator>
<asp:TextBox ID="TxtY" Text='<%#Eval("Y") %>' runat="server" Width="30%"></asp:TextBox>
<cc1:FilteredTextBoxExtender ID="FilteredTextBoxExtender5" TargetControlID="TxtY" FilterType="Custom" ValidChars="-01234567890." runat="server"></cc1:FilteredTextBoxExtender>
Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index after binding the gridview with data i need to set the column width as defined in a array.i am setting it as
string[] cwidth = Session["width"].ToString().Split(','); int colcount = coln.Length; for (int i = 0; i <= colcount - 1; i++) { Gridview1.Columns[i].HeaderText = coln[i].ToString(); int swidth = Convert.ToInt32(cwidth[i]); Gridview1.Columns[i].HeaderStyle.Width = Convert.ToInt32(cwidth[i]); }
I have an array called"List" with 1 item and a gridview "grdWorkingDays" with two columns.
In the First column, I want to display the working days dynamically from the arraylist and in the second column I need to display a dropdown with CL/PL/Halfday(Which has values from a database table and is already written in a method) against each date of array list.
The code is:
int NoOfWorkingDays = List.Count; for (int j = 0; j < NoOfWorkingDays; j++){ String Date = ((Label)grdWorkingDays.Rows[j].Cells[0].FindControl("lblLeaveType")).Text; Date = List[j].ToString();
[Code] .....
When I run this, I am getting error as:
"Index was out of range. Must be non-negative and less than the size of the collection." pointing to the 1st row of for loop.
I am struggling with this for past few days and count find what the error is.
FYI, the array count is being calculated correctly as "1" .
Basically it is the form when user enter all the data and press the submit button then the data will appear on the grid view . On grid view there is option edit when i edit the row and press the update button then the following error will occur
int cid = Int32.Parse(noticeDetails.DataKeys[e.RowIndex].Value.ToString()); "Argumentout of range exception and was unhandled by user code. Index was out of range must be non negative and out of collection the aspx.cs code0
This is my first attempt at paging on a listview. The first time my page loads it loads the listview fine, but when I try to use the paging I get the following error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Here's my code:
[code].....
When I take the following line out I don't get the error, but i need it to populate my controls:
I am inserting some text in texbox and there is range validation set as minimum as 10 and maximun as 100. But when i run the program, though i insert the text atleast or more than 10 characters, it is showing the error message of this range validation. how to set range so that user has to input atleast 10 character minimum ?

I have a table "RANGES" with the following columns
LowRange as int HighRange as int with the data similar to below select * from Ranges LowRange HighRange 1 100 101 200 201 300 . . . 901 1000
And another table "infoDetails" with the following columns
Range as INT amount as money with the data similar to below select * from infoDetails Range Amount 23 34.00 235 44.00 345 34.00 678 100.00 555 100.00 530 100.00 510 100.00 I need one report with the following format without cursor. LowRange HighRange Count Amount 1 100 1 34.00 101 200 0 0.00 . . 501 600 3 300.00 601 700 1 100.00
I have a gridview that displays the total hours and employee works. I also have another column in the gridview that shows the difference from the hours worked and 8.5. I want the column that shows the difference to display the number in red whenever the number is a negative.
The gridview looks like:
Time In Time Out Hours Worked Difference 7:30:00 AM 3:58:00 PM 8.47 -0.03
I would like it to look like:
Time In Time Out Hours Worked Difference 7:30:00 AM 3:58:00 PM 8.47 -0.03
I had a repeater that will be binded using dataset
[Code]....
and on page load I write this code
[Code]....
it worked very well on my machine , after applying it on the server it give the following error
Server Error in '/' Application.
Number must be either non-negative or -1. Parameter name: millisecondsTimeout Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

I want to validate a number by regular expression. Here is the requirement.
1- It should be between 1 and 200 2- maximum 2 floating point (e.g. 24.54 accepted but not 24.546) 3- the radix point can be either Dot or Comma (e.g. 29.45 - 29,45 both accepted) 4- can be intiger in this range also (e.g. 24 or 24.00)
Can anyone post an efficient regular expression for this?
I am getting Range1 and Range2 from database. Dataset is like below.
Range1 Range2
AB100 XY200
AB300 XY400
AB500 XY600
I have to bind these ranges to a Drop Down List as list items includung range number in my application.So list item should be like ==> 1 AB100 XY200 . When user selects a range I have to pass Range1 and Range2 to database.
How can I bind the two ranges with range number to Drop Down List.
I am using the asp.net and framework 2.0 with Ajax enable web.i have a text box and when user will enter "a" or number in this will search the name started from "a" character or number if he or she enter the number basically we can say live-search.
Employee search: Textbox.In this text box she/he will enter the first character of name or first number of employeeno and according to the a character name will search in list.
I have a ListView InsertItemTemplate where there is field (Date) using the AJAX Library CalendarExtender. I want to add some validation to this field, whereby they can't add a date that is later than today. So I have added a RangeValidator and tried to set its MaximumValue to DateTime.Now on Page Load. Unfortuantely it isn't working.
I'm trying to build up some regular expressions to validate some textbox controls. I have done some research and testing but cannot get this one working. Examples of what i am trying to create regular expressions for are as follows:
Range 0-45, 0 decimal places Range 0-20, 2 decimal places Range 16-65, 0 decimal places Range 0-99, 2 decimal places Range 0-1500000, 0 decimal places Range 0-200, 1 decimal place
For 1 and 5 respectively, I have used
([0-9]|[0-9]d|45)$ ([0-9]|[0-9]d|1500000)$
The first one I am having problems for is an age range of 16-65 (inclusive), where I want no decimal places. After a post on here (Regular expression to allow numbers between -90.0 and +90.0) I thought I could use the logic and get it sussed, but can't! The expression I got to was:
