2 guesses where a google search for 'GridViewInsideGridView' lead you![^]

Sonia, you really really must learn how to search the web. There is no way that any programmer can know how to achieve everything and anything. Any decent programmer knows how to search for a concept and change it to their needs.

We really can't do your job for you!

Have you any idea about DataRelation?
If yes follow following code

DataSet ds= //get dataset method here
//your ds returns two table one for parent and second child table.

DataRelation dr = new DataRelation("new_relation",ds.Tables[0].Columns["PKey"],dst.Tables[1].Columns["Pkey"]);
//PKey is PrimaryKey of one table and foreign key of second table that creat //relation.
ds.Relations.Add(dr);
parentGridView.DataSource=ds.Table[1];
parentGridView.DataBind();
//your parent gridview bind with table[1]

Now onRowDataBound event of parent gridview

GridView rp = (GridView)(e.Row.FindControl("ChildGridViewID"));
	rp.DataSource=((DataRowView)(e.Row.DataItem)).CreateChildView("new_relation");
rp.DataBind();

Link to a page which takes the filename off the URL and does a Response.BinaryWrite to send the file into the browser to be displayed.

This is a sure sign that your overall design is broken, because it's working when your code can assume that the client is the server.

If you are using Response.AppendHearder("Content-Disposition"........) remove it, it will be open in same window and will not give you any popup. Add all the content to Response.BinaryWrite(byte[],offset,count);

Try this
string sourceFile = "C:\\Documents and Settings\\PrateekGupta\\Desktop\\pref.xml";

Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = "application/octet-stream";
FileInputStream filIpStrm = null;
MemoryStream ms = new MemoryStream();
filIpStrm = new FileInputStream(sourceFile);
sbyte[] buffer = new sbyte[1024];
int len = 0;
while ((len = filIpStrm.read(buffer)) >= 0)
{
byte[] bbuffer = new byte[1024];
System.Buffer.BlockCopy(buffer,0,bbuffer,0,1024);

ms.Write(bbuffer,0,1024);
}

Response.OutputStream.Write(ms.ToArray(), 0, Convert.ToInt32(ms.Length));

filIpStrm.close();

Response.End();

let me know if it will work for u...

PDF storing in Temporary Folder [modified]

14-Nov-07 22:38

OK, you have a few problems here

1 - binary data is how you want to store it, you just need to turn that data back into an image, which you do by putting it into a memory stream and building an Image out of that.
2 - because you're using ASP.NET, any images you store in the database can only be served inside a page if you feed them out through a HTTPhandler. A far easier approach is to store the images in your file system and store the path to them in SQL Server.

Hi,

I have ASP.NET application in which i am showing some reports in pdf format. Application is login based some have rigths to see the report while some don't. Problem is whenever someone opens reports they are getting stored in Client Temporary folder. Any solution. I cannot change client setting.

I have asked another question in ADO.NET forum, if anyone can give answer to that one too. Here is the link

You can't, the window is going to close before the redirect occurs. The only way to get a message to the server when the window closes is to use AJAX.

MSSQL ? It stores the image as byte format. Choose image datatype.
