I am using the ErrorLbl to capture any errors.
im passing one input parameter to the SP, based on that parameter i have written the code like below create procedure SP1(@inpName varchar(10))
declare @where varchar(20);
if @inpName = 'ABCD'
@where = 'A';
else if @inpName = '1234'
@where = '1';
else if @inpName = 'AB12'
@where = 'A,B';
SELECT * FROM TABLE1 WHERE COLUMN1 IN(@where);
Now the above query was fine if its 'ABCD' or '1234', but if its 'AB12' then query failed.
How to resolve this issue.?

View 3 RepliesBasically, the user Selects a row on GV that executes an Insert into a table the GV cell values of the selected row.
The SQL field data type is varchar. If the GV field is Null, the Insert adds the value to the SQL field. How do I keep the @nbsp; from being displayed in the cell of a data control when it is called at a later time? Do I add some more asp to my control parameter? do I add some vb code behind? Here are some relevant code snippets of existing code.

I'm working on an ASP.NET/C# app.
I have 2 text boxes and I need to validate if the input text for both of them are not both null
ex:
if(string.IsNullOrEmpty(TextBox1.Text) && string.IsNullOrEmpty(TextBox2.Text) ) //FAIL!!! else
that is, at least one txtBox has values
I was planning on using a custom validator but it seems that the validation function only gets called when something is written on the textBox i'm using has the 'control to validate'. Now, that doesn't work for me since I want to show an error message when both text boxes are empty. Is there a way to make the validation function to be called with, for example a postback? Or is there any other better approach to this case than the custom validator?
My site was woking fine, now i noticed that i get an error "Microsoft JScript runtime error: 'null' is null or not an object" when i checked the view source, i saw the following system generated code
<script type="text/javascript">
var Page_ValidationActive = false;
if (typeof(ValidatorOnLoad) == "function") {
ValidatorOnLoad();
function ValidatorOnSubmit() {
if (Page_ValidationActive) {
return ValidatorCommonOnSubmit();
}
else {
return true;
}
WebForm_AutoFocus('txtMailAddress');// --> IS THIS RIGHT???? out side the braces???
</script>
</form>
</body>
</HTML>

If I have a 3 layer web forms application that takes user input, I know I can validate that input using validation controls in the presentation layer. Should I also validate in the business and data layers as well to protect against SQL injection and also issues? What validations should go in each layer?
Another example would be passing a ID to return a record. Should the data layer ensure that the id is valid or should that happen in BLL / UI?
I have a webservice method which needs to accept SOAP as input parameter. I've worked webservices between .NET clients but I've never worked using raw SOAP so I don't know what to do. The format of the input like this:
<?xml version="1.0" encoding="utf-8"?>
<S:Envelope xmlns:S = "[URL]/">
<S:Body>
<ns2:RemoteService xmlns:ns2 = "some.ns.url">
<RemoteServiceInput>
<param1>123</param1>
<param2>Asd Qwe</param2>
<param3 xsi:nil = "true" xmlns:xsi = "[URL]"/>
</RemoteServiceInput>
</ns2:RemoteService >
</S:Body>
</S:Envelope>
How should my method input be to accept this SOAP as parameter?
I am trying to test a SPROC from my ASP.net page by passing a date from my page or from visual studio server manager.
The date value is like so 2009-01-01.
I keep getting an error message this input parameter cannot be converted.
I tried all combinations like '2009-01-01', "2009-09-01" , 20091001.
Nothing seems to work.
But the SPROC works on the SQL side just fine.
I have placed a button inside datagrid.I have use MVVM model to do all manuplation in the grid.
