I have the following code which doesn't seem to work. In the Page_Load function I populate the DataSet and display the results in a grid view.
newsCommand = new SqlCommand("SQL code here", dbConnection);
newsDataSet = new DataSet();
newsDataAdapter = new SqlDataAdapter(newsCommand);
newsDataAdapter.SelectCommand = newsCommand;
newsDataAdapter.Fill(newsDataSet, "Bulletins");
if (!Page.IsPostBack)
{
GridViewMain.DataSource = newsDataSet;
GridViewMain.DataBind();
}
I have some links which call this function to filter the data (yearID is passed as a parameter):
DataTable newsTable = new DataTable();
newsTable = newsDataSet.Tables[0];
DataView dvData = new DataView(newsTable);
dvData.RowFilter = "Year > '" + yearID + "'";
GridViewMain.DataSource = dvData;
GridViewMain.DataBind();
Yet the gridview shows the data it orignally loaded, and not the filtered data. The only thing I can think of is that I'm not using the DataTable in the Page_Load function. What else am I missing?
Thanks,
Adrian
Changed the code in the function to:
DataView dataView = newsDataSet.Tables[0].DefaultView;
dataView.RowFilter = "NewsDate2 Like '%" + yearID + "'";
GridViewMain.DataSource = dataView;
GridViewMain.DataBind();
It must have been something in the RowFilter statement.
