if i use only one ddl, value is inserted into database.
im getting the following error if used three ddl's
Failed to convert parameter value from a String to a DateTime.
string str = DropDownList5.SelectedValue.ToString();
string str1 = DropDownList6.SelectedValue.ToString();
string str2 = DropDownList7.SelectedValue.ToString();
string final = str + str1 + str2;
cmd.Parameters.Add("@startdate", SqlDbType.SmallDateTime).Value = final;

Because, like I hinted in my previous post, the string you build is NOT in a valid date format. Try using the debugger and see for yourself.

yes it is may be due to not parsing the atr in datetime format.
you can try this
str=datetime.parse(str);
then you insert the str
|
|
|
|
|
final = DateTime.Parse(final);
error:Cannot implicitly convert type 'System.DateTime' to 'string'
datetime final1=DateTime.Parse(final);
String was not recognized as a valid DateTime.
|
|
|
|
|
yes your string is not in a valid date time format you can do this by
string final=str1+"-"+str2+"-"+str3;
final=datetime.parse(final).tostring();

Despite me telling you a *better* way, you'll go with the way where you don't have to do any work, you can just copy the code you were given ?

You could be stupid for your country.
That you even tried both of these things tells me you have no idea what you're doing. Stop now, buy a book and read it.
As the other guy said, you need to create a valid date time object. A better solution, is to grab the numbers directly from the drop lists, and build the date time that way.

C# can not convert type 'string' to 'DateTime'.
You can use a datepicker or other date select controls, which can be easily found on the internet.
And you can check the format "dd-MM-yyyy" by regular expressions.

i want to upload a file using a batch file and check the upload staus from asp.net code. please suggest me the proper command line argument in batch file.
mannu

This is idiotic. You obviously have no idea what you're doing. I told you this in the C# forum. Your 'ASP.NET' code runs on the server, by definition. No client side code can run batch files OR upload files. Only a file selection control, with the user selecting files, can do that.

Sounds great. But, what does that have to do with ASP.NET ? I mean, your C# code is not going to run on the client, nor is your batch file going to be on the client. Sounds to me like you're not smart enough to realise that your dev machine is both client and server, so you can write stuff that works there, but won't work when someone is browsing the web and looking at your site.

there is no server side or client side concept with Executing batch file.
mannu

OK, so now I just think you're an idiot. You said you had an ASP.NET question in the C# forum, and you got told to come here. Now you say that your question has nothing to do with a server or client side concept ? Are you totally confused as to what ASP.NET is, and just had a .NET question ? Or are you still confused about what a web app can and can't do on the client side ?

At this point, I am staying up for my own amusement. If you asked a sensible question, I'd happily answer it. Right now, I can't work out what the hell it is you're trying to do, but you're very confused somewhere. I would put to you that anyone else who reads what you posted, will give the answers I gave, so you need to explain at what point it is that you meant to ask something other than what you said, if you want a real answer.
Or you can just do what most people do. Ask the same senseless question again in a few days and in the meantime, tell the guy who is paying you $3 a day that work is going well.

ROTFL !!!!
Well, if you write an ActiveX control, and embed it in your page, then your only issue is security settings in the browser. At this point, your question has NOTHING to do with ASP.NET, because your ActiveX control ( which only works in IE ) is embedded in the aspx, and has nothing to do with any ASP.NET code.
However, I'm not sure how an exe comes into it. I can promise you, I know what an exe is, I've written more than a few. I just understand how web development works, too.

I'm sorry, i tried to stay up to help you, but I guess you've decided on going quiet. I expect you'll ask this exact same question tomorrow. I'd love it if you reworded it so it actually made sense and actually had an answer. But, if you get your project done or not, you gave me a laugh, and you're now immortalised in my sig, so that's got to make you proud at least.

How to set the visibility of a particular row of a gridview is false in the click event of a button.
|
|
|
|
|
It cant be possible you can only hide the row in rowdatabound event.

i have to do it in a button click event.How to catch the selected row from a button click event.
|
|
|
|
|
You can't. He just told you that. How does a button select a row ? Is it in the row ? Then perhaps you can check the parent, or store an id in the button's tag and just remove it from the data source.

Ya, if the button is in a row then you can hide it from row command event, else it is not possible.
