Web Forms :: How To Change Input Format
Feb 9, 2010
I have a matadataclass which I use to show my table individually. No I have the problem that I want to have a kind of input format for my date field like: yyyy/MM/dd and not the german format I'm using on my SQL Server. I already learned from the video that I have to change the display format to show it on my main page. I want to see the two " / " as akind of mask. Sorry for my bad english.
[DisplayFormat(DataFormatString="{0:yyyy-MM-dd}")]
[DisplayName("Delivery Date:")]
public object deliveryDate { get; set; }
Maybe I need a kind of "input validation"? I need the same for my IP field. I have a IP field to add the IP address of a system into my inventory database there I want to have the 3 dots xxx. xxx . xxx . xxx and the range per tree letters from 0-255.
[ColumnOrder(190)]
[DisplayName("Production IP Address:")]
public object IP1 { get; set; }

I'm trying to update a db record via a business object, based on a users input.
In my button event handler, I check for a null or empty value like this before I set the object properties:
[Code]....
But if the textbox is empty, I get the "System.FormatException:
Input string was not in a correct format." in the line:
[Code]....
How can this be?

I'm getting "the input string was not in the specified format" on the last line of code below. The grid is based on a SqlDataSource that has a stored procedure pulling an integer for column 0.
int theUserID = 0;
string theUserFullName =
"";
theUserID = Int32.Parse(gvUserPermissions.Rows[gvUserPermissions.SelectedIndex].Cells[0].Text);

there is a template field in gridview this is basically for showing amount.
<asp:TemplateField HeaderText="Amount" ConvertEmptyStringToNull="False">
<ItemTemplate>
<%#GetQTY1(float.Parse(Eval("Sub_ContractAmt").ToString())).ToString("N2")%>
</ItemTemplate>
</asp:TemplateField>
if my data base field has any value then it shows no error. but if this fiels is null then it shows error
input string was not in correct format while binding the gridview.
so can you please tell me the method that if this field has null value then what should I do so that i dont get this error. this fields might be null.

I'm stumped on this one... it seems really simple, but I can't get around it. I am pulling 2 values (discount percent, discount amount) from a formview label control. I want to use these numbers in a calculation, but I can't seem to get the format correct.
I hit the error on this statement:
DiscountAmt = Convert.ToDouble(fvDiscountResults.FindControl(
"DiscountSubtotal1"
).ToString)

I have an AJAX Calendar extender that puts the date in the textbox in this format: MMMM d, yyyy. I also have a compare validator control that does at DataTypeCheck for DATE. However, when the Calendar Extender enters the date as MMMM d, yyyy (eg. November 2, 2010) the compare validator doesn't like it. It only seems to like the date in the format MM/dd/yy. Not sure how to get this compare validator to accept the input format from the calendar extender?
