I think u just want to know the definition of dataview.
u can assign datatable rows to dataview.
U can add,delete and edit row using dataview.
U can also set true or false to allow to add,delete,edit row of dataview.
U can sort out data using dataview.
U can find rows of dataTable using findRow property of dataview.
There are many properties of dataview.
for more info.. search in google
Best regard

My problem is gridview data does not get exported in explorer whereas when i select firefox it exported to excel.

what could be the reason.
please help.
code to export is
Response.Clear();
Response.AddHeader("content-disposition", "attachmentfilename=FileName.xls");
Response.Charset = "";
// If you want the option to open the Excel file without saving than
// comment out the line below
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.xls";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
GridView1.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();

Hello
If I want to perform a web based installation like what Symantec anti virus provides for installing updates, what are the things we have to take into consideration. I am new to web based development and unaware of the various factors to be considered during web based development. Is it possible in VC++ ?
Thanx.

You however need some client agent running on the desktop to recieve the installables and execute on the system running the web browser (at least an ActiveX Control).

Hi
i am trying to display data on a gridview but it doesn't display anything and it doesn't give any error.
here is my code
string conString = @"Data Source=jakes;Initial Catalog=K2;User ID=sa";
SqlConnection conProcinst = new SqlConnection(conString);
conProcinst.Open();
DataSet dsProcinst = new DataSet();
SqlDataAdapter daProcinst = new SqlDataAdapter();
try
{
SqlCommand cmdProcinst = new SqlCommand("SELECT * FROM _ProcInst", conProcinst);
daProcinst.SelectCommand = cmdProcinst;
daProcinst.Fill(dsProcinst,"_ProcInst");
GridView1.DataSource = dsProcInst;
GridView1.DataBind();
GridView1.AllowPaging = true;

Check whether you query returns any records!
Check your connection string. provide password too

My connection string is fine because i copied.

now it gives me this error.
The data source does not support server-side data paging

I think in ur constring database server name is missing, try to include the server name.

Will @ symbol comes in the connction string.
Mostly the @ symbol will be used for c# coding while giving long path of the source file where two slashes should be used.
Eg: in C# - @"C:/Myfolder/DBname"; or we can write "C://Myfolder//DBname";
Check without using the @ symbol.

here is my code
1. Is your select query returning values in query analyzer ?
2. What is your page size ? Try commenting the allow paging line.
3. Put break point and ensure your dataset contains rows.

I am having two image buttoms - One is ADD button and another is Delete Button, and two dropdownlists one with project names and another ddl with task names of the particular project.
1.) I click the project and onSelectedIndexchanged of project i get the task names and from the tasks i select one task.
2.) Now i want to add new row to the datagrid and when i add i create a row dynamically.
But the values in the previous rows disappear. How do i maintain the selected values of the controls during runtime even if i add aor delete rows.
Can u please help me to find out the solution.

Check when your grid is being filled!
Normally binding values to datagrid would be done in the pageload and when it is not post back.

I have filled my grid and i have written my code after post back only.
here is my code
if(e.Item.ItemType==ListItemType.Item)
{
if(Flag==true)
{
DropDownList drop=(DropDownList)e.Item.FindControl("dd1");
drop.SelectedValue=ddlSelectText;
cmd1=new OleDbCommand("select ptTask from Tasks where ptId="+taskid+"",con);
}
else
{
cmd1=new OleDbCommand("select ptTask from Tasks where ptId=1",con);
}
con.Open();
rd1=cmd1.ExecuteReader();
while(rd1.Read())
{
ddltasks.Add(rd1.GetValue(0).ToString());
}
con.Close();
if(Flag==true)
{
DropDownList tasklist=(DropDownList)e.Item.FindControl("dd2");
tasklist.DataSource=ddltasks;
tasklist.DataBind();
}
This is my code where i have written in datagrid_ItemBinding.Also this is the page load also. But when i add a new row i get the new row but i didnt get any value which i have set for my previous row.
I should get the value be maintained.
What should i do?
