You can just set border="0" on the table which will keep the table invisible
<table border="0" width="100%">
<tr><td align="center" bgimage="downloading.jpg">
<object .... etc.
FLASH
</object>
<td>
</tr>
</table>

Hi everybody.
I got the following Exception when i try to hide a column filled by a dataset:
Index was out of range. Must be a non-negative and less than the size of the collection. Parameter name : index
I dont understand why i got this error because when i try to get a data from this column with Gridview.Rows[myrow].cells[thecellofmycolumn].Text, I have no error.
Does anyone got an idea how to resolve it?
Thx

What's the code that gives the error? Where is it called from?
|
|
|
|
|
I do this in the Page_Load. here is the code:
Gridview.DataSource = MyDataSet;<br />
Gridview.Databind();<br />
Gridview.Columns[1].Visible = false;
When i try to get a value of this column i don t have any error. here is the code to get a value:
string value = Gridview.Rows[MyRow].Cells[1].Text;

I have an asp.net Web App and I have a bunch of classes that hold the information from a page for example, I have a page form.aspx and it initialises a class info.class which holds all the information.
Now when I click a button on that page the class loosing all its values and the are set to null again. Does view state not save this class or is it just for front end things like textboxes,
If I can't do it with view state:
Should i store the class it in a DB
or session var
or in the cache????????
Thanks in advance

You can store it in viewstate, but you have to code it yourself:
Viewstate("MyClass") = myClassInstance
and to return it:
myClassInstance = ViewState("MyClass")
however, your class must be serializable to save correctly. If your class is very large, you may want to consider using session instead, as everything in viewstate will be sent over the wire to the client.
If you store it in cache, then the same data will be used for every user of the application.

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,
AbuBakar

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
---
b { font-weight: normal; }

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.
thanks

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.

Indeed....!
Oh well... thanks for trying folks

Hello There
There is a search form in my scenario in which user will fetch say 100 records in one go. and then he has button "Next 100". Now I am adding the next button dynamically . but the addhandler is not working.
Can any one help me how to make sure that handler should work. The code is
' I have a server side table in which I am adding rows and cells
Dim cellBtnPrevious As New System.Web.UI.WebControls.TableCell
Dim btnRow As New System.Web.UI.WebControls.TableRow
Dim BtnPrevious As New System.Web.UI.WebControls.Button
Dim BtnNext As New System.Web.UI.WebControls.Button
Dim BtnWidth As New System.Web.UI.WebControls.Unit(100)
BtnPrevious.Width = BtnWidth
btnNext.Width = BtnWidth
BtnPrevious.Text = "Previous"
BtnNext.Text = "Next"
AddHandler BtnNext.Click, AddressOf NextRecords
AddHandler BtnPrevious.Click, AddressOf PreviousRecords
cellBtnNext.Controls.Add(BtnNext)
cellBtnPrevious.Controls.Add(BtnPrevious)
btnRow.Cells.Add(cellBtnNext)
btnRow.Cells.Add(cellBtnPrevious)
tblContents.Controls.Add(btnRow)
'' The definition of one function is
Private Sub NextRecords(ByVal sender As System.Object, ByVal e As System.EventArgs)
'' code here
end sub
Thanks

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"
my code for SQL is
Imports System.Data
Imports System.Data.SqlClient
Dim conn1 As New SqlConnection("Server=ibmserver;database=Northwind;User id=ADMINISTRATOR;Password=ADMIN")
conn1.Open()
Dim ds1 As New DataSet
Dim str1 As String = "select * from_categories"
Dim str2 As String = "select * from products"
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()
******************************************************************************
my code for oracle is
imports system.data.oledb

dim myDa as oledbDataAdapter
dim myDa1 as oledbDataAdapter

dstDT = new dataset()

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.
