Hi All
I have a datagrid & I want it to be sorted when the user clicks on the column header..How can I do that??
Thanks a lot in advance

it's very simple
use this function in your class file or at code behind
public void BindGrid(DataTable dt, DataGrid dg, string sortexpression, string order)
{
try
{
if (dt.Rows.Count > 0)
{
DataView dv;
dv = dt.DefaultView;
if (sortexpression != "")
{
if (order == "desc")
dv.Sort = sortexpression + " DESC";
else
dv.Sort = sortexpression;
}
dg.DataSource = dv;
dg.DataBind();
}
}
catch (Exception ex)
{
clsLog.WriteLog(ex.Message);
throw ex;
}
}
where, argument1=datatable object where you hv stored the data which you would like to display
2.argument2=your datagrid id
3.argument3=variable(here u cn take sortexpression which you will declare at the beginning like this private string sortexpression = "";)
4.argument4= Convert.ToString(ViewState["order"])
now on click of column_header event write the code
LinkButton lnkbtn;
lnkbtn = (LinkButton)sender;
if (Convert.ToString(ViewState["order"]) == "Asc")
{
ViewState["order"] = "desc";
}
else
{
ViewState["order"] = "Asc";
}
if (lnkbtn.Text == "1st column headername")
{
sortexpression = "1st column headername";
}
if (lnkbtn.Text == "2ndcolumn headername")
{
sortexpression = "2ndcolumn headername";
}
fillgrid();
(i think u know what to write in this function here just bind ur grid and one more thing in this function call the sort function with required paramts mentioned above)

Change the allowSorting datagrid property to true
go to Columns property, select the field what you want to sort, write onto the SortExpression the same column datafield.
On datagrid sorting function
<br />
protected void Grid_Sorting(object sender, GridViewSortEventArgs e)<br />
{<br />
string sql = "SELECT * FROM table WHERE conditions ORDER BY " + e.SortExpression;<br />
SqlDataAdapter data_Adapter = new SqlDataAdapter(sql, conexxxion);<br />
DataSet dataSet = new DataSet();<br />
data_Adapter.Fill(dataSet);<br />
Grid.DataSource = dataSet.Tables[0].DefaultView;<br />
Grid.DataBind();<br />
}<br />
you can do it with all datagrid columns

The simple answer is 'You can not'. The only FileOpen dialog you get is 'Browse' using , which creates a textbox and a button. Anything else might need ActiveX.

I see,it is XslCompiledTransform, in vs2003 we use XslTransform instead of it. In the FAQ of that article there is some detailed info about it(its name is "Net 1.1 version").;P

Thanks Steven.
I got the program working but i wasn't used to the XSL. After go'g thru the necessary docs i became somewhat familiar with that too.
Still the data from the dataset is not getting populated in the Excel sheet. As I went thru the XSl doc i came to know that
"<xsl:for-each select="NewDataSet/Table">"
The select keyword will select data from each inner node as per the depth specified. But here instead of XML file we are using dataset.
"<xsl:value-of select="ProductID"/>"
The select in here ---say "ProductID" IS it the field names that should be given as per our select commnd.
Is my problem something to do with the above.
Can u Plz suggest a possible solution for the same.
Thanks & Regards,
Jeeva

dataset is ok, i am just using dataset, u could use:
strExcelFile= objExport.TransformDataTableToExcel(ds.datatable(i),True)
objExport.SendExcelToClient(strExcelFile)
Also u have to have some polishment of ExcelExport.vb so as to run it in vs2003.
If u have any more question, u could sent email to me.
wish u could succeed!;P
Regards,
Steven

You can get that like this:
dataset.Tables[0].Rows[0][0].ToString();
This will give you the value of the first column of the first row of the dateset.

u can use
dataset.table["table name"].Rows[row number]["column name"];

private string GetWebContent()
{
string fullpath = @"http://www.google.com";
HttpWebRequest webreq = (HttpWebRequest)System.Net.WebRequest.Create(fullpath);
HttpWebResponse webresp = (HttpWebResponse)webreq.GetResponse();
StreamReader strm = new StreamReader(webresp.GetResponseStream(), Encoding.ASCII);
String text = strm.ReadToEnd();
strm.Close();
return text;
}
This is my code. it works well on my own computer, but when i put in my office computer, there is a WebException:
"The underlying connection was closed: Unable to connect to the remote server."
why? is it because the setting of firewall in the office server or something.
Thanks very much
