Is there a way to use RangeValidator for large numbers (Int64 range)?

When using a range validator, if the user exceeds the defined range, How do you code it so it disables a button so the user can't continue. (without using JavaScript)

I want to validate textbox, so user enter greater than 30
if user enter lessthan 30 than message will display.. for that i use range validator of asp.net
<asp:TextBox ID="txtprice" runat="server" CssClass="textbox" Width="180px"></asp:TextBox>
<asp:RangeValidator runat="server" Display="None" ID="range1" ValidationGroup="grdsave"
SetFocusOnError="true" ControlToValidate="txtPrice" MinimumValue="30" MaximumValue="999"
ErrorMessage="Minimun budget is 30 USA dollor"></asp:RangeValidator>
It give message if i enter less than 30. but if i enter 100 or 200 it also give message. How can i allow that value?
it is a simple question, but i didn't understand. here is the code below:
Private Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowCreated
Dim drv As DataRowView
If e.Row.RowType = DataControlRowType.DataRow Then
For i As Integer = 0 To e.Row().Cells.Count
If " ".Equals(e.Row().Cells(i).Text) Then
e.Row().Cells(i).Text = ""
End If
Next
End If
End Sub
the line "If e.Row.RowType = DataControlRowType.DataRow Then" occured exception below System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection
I am getting error Specified index out of range of valid values. Parameter name index. I tried to put a breakpoint and see where am I getting the error. I have 5 columns (1 hidden). first 3 columns- no issue. But when the control reaches the 4th column it throws the error. I saw that I am getting correct values for the first 3..no ide what is going wrong with the 4th one.

when vieing a page with a datalist on it. i have other controls in the datalist. what would cause this? here is my code behind.

HyperLink hp2 = DataList1.Items[0].FindControl("HyperLink2") as HyperLink;

I recently had to remove a field from my datakey on all three gridview tables. On the top level table the field (ignum) remains as a non key field. On the two lower level tables it was removed completely. Now, the top level gridview opens correctly, but when I click on select this should bring up all the records in the second gridview associated with the selected row in the first gridview, but I get the following error:
[Code]....
I've looked at everything I can thing of and everything looks ok. The tables look good, I've removed all references to the removed field and I've restructured all the code to account for the changes. I'm missing something, but I don't know what. I've gone through debug step by step and the error occurs as I leave the GridView1_SelectedIndexChanged code. It goes down to the End Sub line with no errors, but when I step again it errors out. Here is that section of code.

I have data from multiple tables that I would like to display in a gridview via a stored procedure. I need to select the data based on a date range and display it. Once displayed I need to include a button that would allow the user to export the gridview data to an excel spreadsheet. Does anyone have an out of the box solution or know of a tutorial I can use to accomplish this feat? I am currently using 2.0 for this project. I am newish to .net.
Here is my stored procedure that calls the data from multiple tables.

I have used to code below successfully to export a gridview to an excel spreadsheet, however when i use it for a gridview with data from a different table i receive the following error:
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
The thing is it works locally fine but when i upload to my shared server i receive the error above?
how to resolve/troubleshoot this?

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.

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:

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:
DataKey currentDataKey = this.lvReports.DataKeys[currentItem.DataItemIndex];
This must be easier than this: I want to highlight a range of dates, in this case: All dates after today. The only control I can see which allows me to wire-in to a date based X-Axis is the Stripline So, I get today's date minus my earliest date in the dataset in days... No problems. So to set up the Stripline I try something like:
[Code]....
and ends up looking like: Today is where the second shade begins. This is fine, but it is looping over 12 months. The number of days since it began is 399 days. I was hoping that would have actually meant the offset was 399 days. Am I trying too hard with the wrong class? Is there something else I should be using?
i use objectdatasource control for bind record and also in gridview paging.in my gridview there is a linkbutton(edit) when i click it then it redirect to next page with some key value.but problem is when i try to paging in gridview an error is occure that is Index was out of range.

A dataview is throwing an out of range exception when a page submit button is clicked. The strange part is if you change the data in the dataview by selecting a different person in the DDL the page works fine. Its only when the page loads and the default person in the DDL is when the DataView throws the exception.
The exception is thrown on the last line when I add DV.Rows(0).Cells(1).Text to the id_num parameter. I know there is a value in the dataview because it is displayed on the page. I can refresh the dataview with another person's information and the code works fine. This really has me confused. Here is a bit of the code behind.
