Extending WebPartManager class

Hi all,

I'm trying to save changes made to a web parts page to the db, I can add the webparts programatically but they disappear on the first postback. I've read about extending the WebPartManager class to use the SetPersonalizationDirty() function, but as I'm still fairly new to using WebParts I'm not sure how to do this.

Basically what I would like to know is how to gain access to the class itself to write an override function, or whether or not I can put the function in the existing code.

Thanks in advance for any help or suggestions, Cheers.

A humble novice,
Lil Turtle

Hi there,
Because the SetPersionalizationDirty is defined as below:

protected void SetPersonalizationDirty ()

So you cannot override this method, what you may do is to inherit from this class, and define a new public method which in turn calls the protected method SetPersionalizationDirty. The sample code looks something like;

public class MyWebPartManager : WebPartManager
{
    public void ExSetPersonalizationDirty()
    {
        SetPersonalizationDirty();
    }
}

To maintain the view state of a dynamically created control

I created a drop downlist dynamically and i am unable to capture its values i.e its view state.

I know that view state can't be retained for dynamically created controls .pls suggest a way out to retain the view state.

Actually, the dynamic control can persist data in the ViewState as the static control does. The important thing when working with the dynamic control is that you need to choose the right event to readd the dynamic controls. If this happens after the ViewState is loaded, then it will loose its ViewState data. For more information, you should read about the control life cycle in MSDN.

if you want to see the selected value each time, it is easy...

give it an ID, say idListBox.

while creating it, get the value from form variables to determine the selected value:

...
selVal = request.forms("idListBox")
loop
create a list item
if value of the item = selVal then add "selected" to the item
add item
end loop
...

That's it...

First parse the string into a DateTime value:

DateTime theDate = DateTime.ParseExact(theString, "dd/MM/yyyy", CultureInfo.InvariantCulture);

Then you can use the DateTime value in the call to the database.

Well it is very simple to create excel files from asp.net code.

The following is the sample code to create one with font and style settings etc.

----------------------------------------------------------------------
//Write a table structure with all formatting you need (e.g. font, etc.)
string strHtml="

strHtml+= ""

strHtml+=""

strHtml+=""

strHtml+="

Name	Color	Formatting
Ketan	This is Red Color Font	None
Abc	NA	None
Xyz	NA	This is bold text

"

//Clear the Response Headers
Response.Clear();

Response.Charset = String.Empty; // String.Empty();

//Set Content Type and add header
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "attachment; filename=abc.xls;");
this.EnableViewState = false;
System.IO.StringWriter myTextWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter myHtmlTextWriter = new System.Web.UI.HtmlTextWriter(myTextWriter);
HtmlGenericControl gn = new HtmlGenericControl();
gn.InnerHtml=strHtml;
gn.RenderControl( myHtmlTextWriter);
Response.Write(myTextWriter.ToString());
Response.End();
----------------------------------------------------------------------

If you need to embed excel sheet functionality, you need to work out more. Poke tongue | ;-P

Ketan Majumdar.

There are a couple of ways to create the Excel document:
+ Use the Automation to create the Excel file, however this option is not recommended at the server side.

+ Create the Excel file in XML format.

+ Use a third party component to generate the Excel file without using Automation.

Just follow the instructions given below
First of all,take datagrid from toolbox and paste it on webform1.aspx

1) Now Use some database to connect to table. Use its connection string.
e.g. Dim con as new sqlconnection
con.ConnectionString="Data Source=servername;Initial Catalog=pubs;User Id=sa;Password=sa;Persist Security Info=False;";

2) dim ds as dataset()

dim cmd as sqlcommand = new SqlCommand()
cmd.Connection=cn
Dim Query As String = "select * from EET_ACCRIGHTS"
'use above code for ref.
Dim MyCommand As SqlDataAdapter
MyCommand = New SqlDataAdapter(Query, con)

DS = New DataSet
MyCommand.Fill(DS, tablename)

3) Now use following code

If con.State = ConnectionState.close Then
con.Open()
End If
datagrid1.datasource=ds.tables(0)
datagrid1.databind()
If con.State = ConnectionState.Open Then
con.Close()
End If

Hello All,

I created a bit map and it is saved to a jpg file. The code is:-

oBitmap.Save("c:\\codes\\gen_img.jpg", ImageFormat.Jpeg);

I want the file to be given by the user(save dialogbox should come and the filename should be given by the user and the location "SHOULD BE" on the server),i.e, i need to get the location as well as the filename from the dialog box and should be given instead of the hard-coded one.

Hope Anyone can find me a Solution for this!
