Hi friends,
I am using template fields in my gridview to display the contents. I am also including Edit and Delete CommandField. Its working perfectly. When I click Delete the particular row is deleted. But for me, when i click delete it should give some confirm msg like "Do u want to delete" if i click yes it should delete that row r no then it should leave that field.
Please Help Me.
Thanks in Advance.
Regards,
Prya

Hi ALL
I want to share a web.config file for two projects.
I am using .Net 1.1 to create the web application.
I am having a solution and two different projects under the solution.
I want to keep one web.config file for these two projects.
Can I ?
Thanks in advance.

Ok so I have an aspx page with a function in the backend aspx.vb page to display a div(has to be done server side) I have a usercontrol on the page which contains a grid. Now onclick of a button on the grid in the usercontrol, I want to call the function on the main page from the usercontrol. Is there an easier way than to make the function on the main page a shared function, this seems messy, could I somehow use the parent attribute??
Thanks a mil in advance

You should be able to access page containing user control as this.Page, cast it to type of your page and then you can call its public methods.

That is excatly what I was looking for, Thank you very much dnh, but I think you have to use Parent.Page for the usercontrol and not this.Page, maybe that is just for my case but anyway thanks again

hmm not really, Control.Page[^] property really points to aspx *page* where your user control is, on the other hand Parent points to control that directly contain your user control, e.g. if it is in Placeholder, Parent will be that placeholder. They both should have same Page...

Well I want to access Functions on the page that the user control is contained in. So if I have a page called Maintenance.aspx which contains a usercontrol now I want to access a function on maintance.aspx.vb from the usercontrol I would have the following code in the usercontrol server side:
Dim maintenance As Maintenance
maintenance = CType(Parent.Page, Maintenance)
maintenance.viewQuestions() 'where viewQuestions() is a public function contained on the main page
This works fine for me as is, yet I stand to be corrected, I am I missing something?
Sorry if I have not explained this properly

cullyk wrote: maintenance = CType(Parent.Page, Maintenance)
could be as well
maintenance = CType(Page, Maintenance)
It's just that you said you have to use Parent.Page.

My application needs Exports to Excel and From Excel to Database
for that ,i have used the code
For Export:
Dim mySQLCommand As New SqlCommand
Dim myConnection As New SqlConnection
Dim datagrid1 As New DataGrid
Dim DS As New DataSet
Dim DT As New DataSet
myConnection = New SqlConnection("Password=technologies;Persist Security Info=False;User ID=sa;Initial Catalog=Lims_Demo;Data Source=VISHWA") 'ConfigurationSettings.AppSettings("MyConStr"))
myConnection.Open()
Dim da As New SqlDataAdapter("SELECT top 30 ProductCode,ProductName,GenericName,RetestPeriod FROM Results where status=0", myConnection)
da.Fill(DT)
datagrid1.DataSource = DT
datagrid1.DataBind()
Response.Clear()
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
Me.EnableViewState = False
Dim tw As New System.IO.StringWriter
Dim hw As New Html32TextWriter(tw)
datagrid1.RenderControl(hw)
Response.Write(tw.ToString())
Dim path As String = "C:\...\abc.doc"
Response.AddHeader("content-disposition", "attachment; filename=Worddocument.xls")
Response.End()
'FileStream sourceFile = new FileStream(path, FileMode.Open);
'long FileSize;
'FileSize = sourceFile.Length;
'byte[] getContent = new byte[(int)FileSize];
'sourceFile.Read(getContent, 0, (int)sourceFile.Length);
'sourceFile.Close();
'Response.BinaryWrite(getContent);
'dim SaveFileDialog1 as System.
'If SaveFileDialog1.ShowDialog() = DialogResult.OK Then
' RichTextBox1.SaveFile(SaveFileDialog1.FileName, _
' RichTextBoxStreamType.PlainText)
'End If
myConnection.Close()
the above coding is working very good and giving the required results
but when i am going to Import Excel data to Database
I have used the code, which i found in Msdn help
'---------------------Importing Data From Excel to Database
If Not FILE1.PostedFile.FileName = "" Then
FilePath = FILE1.PostedFile.FileName
End If
'Excel Work Sheet Database Connection
MyConnection = New System.Data.OleDb.OleDbConnection( _
"provider=Microsoft.Jet.OLEDB.4.0; " & _
"data source=" & FilePath & "; " & _
"Extended Properties=Excel 8.0;")
'Select the data from Sheet1 of the workbook.
'MyConnection.Open()
'Dim dt As Table = MyConnection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null)
Dim f As Array
f = Split(FilePath, "\")
Dim k As Integer = f.Length
Dim str As String = f(k - 1)
Dim filename As String = str.Substring(0, str.LastIndexOf("."))
'str.Split(".xls")
'Dim f1 As Array
'f1 = Split(str, ".")
'Dim str1 As String = f1(f1.Length - 1)
Try
Dim str2 As String = "select * from [EXPnIMP$]"
'Select the data from Sheet1 of the workbook.
'MyCommand = New System.Data.OleDb.OleDbDataAdapter( _
' str2, MyConnection)
''' Select the data from Sheet1 of the workbook.
'MyCommand = New System.Data.OleDb.OleDbDataAdapter( _
' "select * from [" & filename & "$]", MyConnection)
MyCommand = New System.Data.OleDb.OleDbDataAdapter( _
"select * from [" & filename & "$]", MyConnection)
DS = New System.Data.DataSet 'DataSet
MyCommand.Fill(DS) 'Filling The dataset

it is also working fine,but it is working only for Excel sheet , which i create
it is not working for the excel sheet which i created by using the above code
it is giving the below error,
i think the errror may be in exporting to excel,
when i put google search,it is showing that, file should be exclusive,how can we set exclusive to a file
the error , i am getting is :
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC Microsoft Access 97 Driver] The Microsoft Jet database engine cannot open the file '(unknown)'. It is already opened exclusively by another user, or you need permission to view its data.

After you export the data to the excel file close it and then try to export the data from excel to database.

<compilation debug="true" />

The "who" who is using the image is probably you the first time you uploaded. Make sure that you are properly disposing of objects that you use when dealing with the image. One of them must still be holding on to the image file.
I've done had this problem before when using a System.Drawing.Image object in my code to deal with a file. After you are done with it you must dispose it to get it to release it's hold on the file. This is my example:
Dim x as System.Drawing.Image<br />
x= Drawing.Image.FromFile(strMyImageFilePath)<br />
x.Dispose()
Hope this helps.
