View 5 RepliesI've just encountered an interesting problem in a standard BoundField in a GridView. The field is for EmployeeCode, which is purely numeric, but stored in a character column in the database. The DataFormatString="{0:00000}" attribute on the BoundField doesn't work, as I assume that format is only for numeric values.
To work around this, I had to use a TemplateField, and bind the text value using the attribute Text='<%# PadNumericString(Eval("EmployeeCode").ToString(), 5) %>'. Is there no simpler way of doing this?

View 3 RepliesI have a gridview control that has two bound fields. I want to restrict the user's to enter only numeric values in the second bound column. I went into the properties of the gridview control. Selected "Columns" and clicked on collection. The fields showed up.

I need to make sure a user can only enter numeric values for my Invoice Amount Textbox. It is a decimal field in my database.
I came across the MaskedEditExtender. It seemed like the solution for the problem. However, say I want to enter an amount of R50.00
The mask is set to 9,999,999.99.
When the textbox looses focus the amount becoomes 5,000,000.99.
Is there a better way that I can achieve this??
Code:
<cc1:MaskedEditExtender ID="InvoiceAmountMaskedEditExtender" TargetControlID="txtInvoiceAmount"
Mask="9,999,999.99" MessageValidatorTip="true" MaskType="Number" AcceptNegative="Left"
DisplayMoney="Left" ErrorTooltipEnabled="true" runat="server">
</cc1:MaskedEditExtender>
For efficiency's sake I've created a number of stored procedures to run against an SQL table. Which procedure runs depends upon the checkboxlist choices a user makes before clicking a button. The checkboxlist looks something like this:
<asp:CheckBoxList AutoPostBack="True" runat="server">
<asp:ListItem Enabled="True" Value="1">Item 1</asp:ListItem>
<asp:ListItem Value="10"> Item 2</asp:ListItem>
What I can't figure out is how to loop through the checkboxes in the Button1_Click event in the .cs code behind page to add up the values of the selected items. (The value of an unclicked box being 0.) Converted to a string, the totaled value is then appended to a stored procedure name (MyPROC) for entry into the SQL statement. In other words, if the user clicks just Item 1, then the Button1_Click event would produce a stored procedure name of MyPROC1, insert it into the statement, and fire off the query; if Item 1 and Item 3 are selected, then MyPROC101 would be called.
My second question is: how do I place the concatenated string into the SQL statement?
This might all seem a bit unorthodox, but given the number of variables going into statement, it seems to this newbie the best approach.

I am using Asp.net 3.5 listview control. In item_updating event I am using this code...
dim country as string = Dim country As String = e.NewValues("country_name").ToString.Replace(" ", "")

View 4 RepliesI'm using Microsoft Oracle Data Provider(System.Data.OracleClient). As soon as I get the string (SC1101E,B+,) in my input parameter, I get the below error:-
"ORA-06502: PL/SQL: numeric or value error: character string buffer too small"
Strange, as this same query works completely fine with my SQL client/toad.
The database type is varchar2 with 2000 length. A lot of longer strings easily able to be updated. But as soon as above string get in the parameter, the code starts vomitting error.

I have a SQL query I'm running in an ASP.NET page. The final parsed SQL needs to contain a list of string values in the WHERE [columnname] IN [values] format. For example, the final query might look something like this:
SELECT PRODUCTNAME FROM PRODUCT WHERE PRODUCTCODE IN ('ABC','DEF','GHI','JKL', /* etc */);
However, the string values in the WHERE clause need to be dynamic. Normally I use parametrized queries to make my code convenient and safe, so conceptually I'd like to do something like this:
String[] productCodes = { "ABC", "DEF", "GHI", "JKL" };
SqlCommand cmd = "SELECT PRODUCTNAME FROM PRODUCT WHERE PRODUCTCODE IN (@ProductCodes)";
cmd.Parameters.Add("@ProductCodes", productCodes);
However, this sort of functionality doesn't appear to exist in .NET. How should I go about implementing this? I could use a foreach loop on the array and run a query with a single value as a parameter for each value, but there could potentially be a hundred or so different values in the array and it seems like querying them separately would be very inefficient.
I've read another question where someone suggested a solution for strongly-typed int parameters, but that method would make me nervous about SQL injection when used with String values, especially since the client may very well be able to influence the input values.
How would you implement this query functionality?
