you can do it like:
//hide
document.getElementById("TextBox1").style.display = "none";
//show
document.getElementById("TextBox1").style.display = "block";

So your web.config looks like this:
<configuration>
<system.web>
<sessionState
mode="InProc"
timeout="60" />
</system.web>
</configuration>
??
What are you setting the session values to blank? I would think in the session_end event you would set them to null so the memory would be freed. There is no reason to initialize them to blank. In your code check to see if the session varable is null or Nothing if you are using VB.net

Ascii value for enter key is 13. You need to write OnKeyDown javascript event for your textbox and call function. Check event.KeyCode is 13, if yes use controlname.focus() to set focus to other textbox.

dtData.Columns.Add("Column2")
dtData.Columns.Add("Column3")
dtData.Columns.Add("Column4")
dtData.Columns.Add("Column5")
dtData.Columns.Add("Column6")
dtData.Columns.Add("Column7")
Dim fInfo As FileInfo
fInfo = New FileInfo("C:\test.xls")
Dim sw as System.IO.StreamWriter("C:\test.xls")
Dim sepator as string = "\t"
Dim intColumnCount as integer = dtData.Columns.Count
for i as integer = 0 to intColumnCount -1
sw.write(dtData.Columns(i).ColumnName)
if i < intCount-1 then
sw.write(sepator)

Hi all
I am Trying To edit a datagrid
I am using this code
http://msconline.maconstate.edu/Tutorials/ASPNET1/default.htm[^]
But iam getting this Error
"Object reference not set to an instance of an object"
"ItemNumber = CType(Args.Item.FindControl("ItemNumber"), TextBox).Text
"
Can any one tell what wrong on my code
THAN Q

Your core problem is that you're using code blindly without understanding what it does. What this does, is it looks for a control, and it assumes it will find it. As such, this is bad code.
The 'ItemNumber' control is not found, so Nothing is returned. Which is what the error means.

Thx for reply
"The 'ItemNumber' control is not found, so Nothing is returned. Which is what the error means."
Dim ItemNumber As String
The 'ItemNumber' control declared in the code as a String
How can find the control
Thx

you can use DataGridItemEventArgs object to find out the textbox.
for example in C#:
Private void DataGrid1_EditCommand(object sender,DataGridItemEventArgs e)
{
TextBox txt=(TextBox)e.item.FindControl("ItemNumber");
txt.SelectedValue=" ";
}

Hi all,
I have a GridView that gets populated with a sqldatasource, then I have a detailsview that I use to update the values in the database, the gridview has autogenerateselect=true and when you select the row it should populate the details view, but I'm having trouble and the only reason that I can think of is because I have 2 columns as the primary key, because when I click on the select button on the gridview the detailsview just disapears. Can anyone please point me into the right direction as how I could fix this.
Here is the code that I use.
<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1"
DataKeyNames="menu_id,menu_language" AutoGenerateColumns="false" AutoGenerateSelectButton="true" AllowPaging="true">
<Columns>

<asp:BoundField ReadOnly="false" HeaderText="Text" DataField="menu_text" NullDisplayText="N/A" />
<asp:BoundField ReadOnly="false" HeaderText="url" DataField="menu_url" NullDisplayText="N/A" />
<asp:BoundField ReadOnly="false" HeaderText="Avtive" DataField="menu_active" NullDisplayText="N/A" />
<asp:BoundField ReadOnly="false" HeaderText="Content Id" DataField="menu_content_id" NullDisplayText="N/A" />
</Columns>
</asp:GridView>
</div>
<div>
<asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px"
DataSourceID="SqlDataSource2" AutoGenerateRows="false" DataKeyNames="menu_id,menu_language"

hi,
Delete all session setting from web.config file or apply default setting at there. The default setting for SessionState is "InProc".
Try this.

For deleting use System.IO.File.Delete("fullfilenamewithpath");
