How to pass Mulitple values through 'location.href' ??

Hello,

Hope you all will be fine,I want to send multiple values through "location.href" after getting these values from DropDownList in ASP.net using C#, How can i do that? the DropDownList is in HTML not <asp:dropdownlist>. The code is like that;

location.href='addsuccess.aspx?color='+<%=colordropdown%>.options[<%=colordropdown%>.selectedIndex].value

Moreover I am calling this on "onClick" Event of an Image.

Hope you will understand,

Regards,

Would it not need to be something more like this:

location.href='addsuccess.aspx?color='+<%=colordropdown.options[colordropdown.selectedIndex].value%>

Yes paddyboyd you are right it is working quite well but in this way i can only pass one value like color but in real case i want to pass more than one value so how is it possible to pass more than one values in following string ???????
location.href='addsuccess.aspx?color='+<%=colordropdown.options[colordropdown.selectedIndex].value%>
Regards

Separeate the values using the & character, e.g. create an url in the format:

addsuccess.aspx?color=3&something=42

Create Directory.....

Hi,

If I want to save an uploaded file to subfolderX I can use this:

objFile.SaveAs(Server.MapPath("subfolderX\" & savedFilename))

OK, no problems. But now I want to check that subfolderX exists, and create it if it doesn't. So I do this:

If Not System.IO.Directory.Exists(Server.MapPath("subfolderX")) Then
System.IO.Directory.CreateDirectory(Server.MapPath("subfolderX"))
End If

OK, no problem. This works.. on my local machine. When I try it on my ISP's server I get an error: "Could not find a part of the path e:"

When I contacted them they suggested I try hard-coding the fully qualified network path instead:

If Not System.IO.Directory.Exists("\\iisX\domains\x\....\subfolderX") Then
System.IO.Directory.CreateDirectory("\\iisX\domains\x\...\subfolderX")
End If

This works - but why doesn't Server.MapPath, esp given that it DOES work for saving files??!! This doesn't make sense to me...

I don't want to use the hard-coded version if possible, as it doesn't lend itself well to the application's portability.

Any deas, anyone...?
thanks
Phil

Try printing out what path the Server.MapPath() method returns, and see if this helps.
The reason the createdirectory doesn't work seems to have to do with the fact that your application is hosted on a different machine internally in the hosting company, since you have to give them the full networkpath.

How about it if you try with the Tilde "~" character (implying the current application)?

Server.MapPath("~/subfolderX")

I have - it gives "e:\...." (etc)

Same as above.

Weel, yes... but why then does

objFile.SaveAs(Server.MapPath("subfolderX\" & savedFilename))

work fine but

System.IO.Directory.CreateDirectory(Server.MapPath("subfolderX"))

not? That's the really puzzling thing.

I dont think anyone other than your hosting comany could possibly give you a definitive 100% accurate answer - but the chance of finding and speaking to a programmer there that understands such matters is slim!.

I can tell you that Server.MapPath works better the more of the path it has to go on. So, in your case you say that this works:

objFile.SaveAs(Server.MapPath("subfolderX\" & savedFilename))

so you are giving it quite alot to go on
Server.MapPath("subfolderX\myfilename.ext")

the one you say does not work has less to go on
Server.MapPath("subfolderX")

if you know the folder above subfolderx, you might try prepending that to give MapPath more of a hint, but I cant guarantee that will make any difference whatsoever.

Thanks - but didn't help.

This is so odd - the line that checks if the folder exists works:

If Not System.IO.Directory.Exists(Server.MapPath("subfolderX")) Then

because if I replace subfolderX with one that does already exist then it returns true; but if subfolderX doesn't then

System.IO.Directory.CreateDirectory(Server.MapPath("subfolderX"))

fails with a "Cannot find part of path" error. As I can create folders by hard-coding the network path I assume it isn't a permissions thing. (Unless there are different permissions to creating network folders from virtual ones..? Never have understood this side of things...) And saving files works.

I am defining relationship between datatables by using oracle as the backend.
It works fine in sql but in oracle it prompts an error "OBJECT REFERENCE NOT SET TO AN INSTANCE OF AN OBJECT"

Dim adapter1 As New SqlDataAdapter(str1, conn1)
adapter1.Fill(ds1, "categories")
adapter1.SelectCommand = New SqlCommand(str2, conn1)
adapter1.Fill(ds1, "products")
ds1.Relations.Add("categories_products", ds1.Tables("categories").Columns("categoryID"), ds1.Tables("products").Columns("categoryid"))
Dim categories As DataTable = ds1.Tables("categories")
DataGrid1.DataSource = ds1.Tables("categories")
DataGrid1.DataBind()
DataGrid2.DataSource = ds1.Tables("categories.categories_products")
DataGrid2.DataBind()

If it is a server control then you set the text like this:

YourButtonName.Text = "whatever";

if it is a HTML input tag then you set the value attribute.

Hi,

Below code solves your problem.

<script language='javascript'>

function newtest()
		{
                //check box checked
		if(document.getElementById("CheckBox1").checked == true)
		  document.getElementById("DropDownList1").disabled = true;
                else  //check box uncheck
                  document.getElementById("DropDownList1").disabled = false; 
		}

</script>

Add the below code inside checkbox tag..

OnClick="newtest()" 'removed' text has to be changed to 'onclick'

Hope this helps you... Smile | :)
