Is it compulsory to design crystal Report In Asp.Net...
Can We Use Dataset Or DataTable Directly Without Designing Crystal Report???
When i m Trying it returns Error.
Any Idea Please Help

For filtering filter using session which will hold value after postback

You have to write textbox value in session

write code where you using sql expression..

Eg..

String sql="Select * From Table_Name ";

If(!String.IsNullOrEmpty(txtFirstname.text))
{
sql+= txtFirstname.text;
}

===============
The code below works when columns are created explicitly as declerative >><asp:BoundField DataField="ID" HeaderText="ID" SortExpression="" />
===============

AllowSorting

="True"
OnSorting

="GvEvent_Sorting"

<

asp:TemplateField ItemStyle-HorizontalAlign="Right" HeaderText="MyDate" SortExpression

="MyDate">

#region GV_sort event and Sort Direction

protected void GvEvent_Sorting(object sender, GridViewSortEventArgs e)
{

//Retrieve the table from the session object.
DataTable dt = Session["MyDS"] as DataTable;
if (dt != null)
{
//Sort the data.
dt.DefaultView.Sort = e.SortExpression + " " + GetSortDirection(e.SortExpression);
GridView Gv = (GridView)sender;
Gv.DataSource = Session["MyDS"];
Gv.DataBind();
}
}

private string GetSortDirection(string column)
{
// By default, set the sort direction to ascending.
string sortDirection = "ASC";
// Retrieve the last column that was sorted.
string sortExpression = ViewState["SortExpression"] as string;
if (sortExpression != null)
{
// Check if the same column is being sorted.
// Otherwise, the default value can be returned.
if (sortExpression == column)
{
string lastDirection = ViewState["SortDirection"] as string;
if ((lastDirection != null) && (lastDirection == "ASC"))
{
sortDirection = "DESC";
}
}
}
// Save new values in ViewState.
ViewState["SortDirection"] = sortDirection;
ViewState["SortExpression"] = column;
return sortDirection;
}
#endregion
