I want to filter data on the textchange event on listview so I use dataview to filter data. Issue in the below code is, I use dataview inside for each so that it checks only one condition that is last value only it takes, I want to check value in s1 with dataview and remaining value should bind with listview.
eg: if I type an in textbox it should list all the item values starting with an value like anandha kumar,anna ect. suppose I keep the value anandha kumar and anna in array s1. I should list all other values expect the array values like antony ect... in listview.
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
dvProducts = (DataView)Session["ListViewItems"];
string serachText = EscapeLikeValue(TextBox1.Text);
string lvValues = hdRetailCustomerGroup.Value;
string trim = lvValues.Replace(" ", "");
trim = trim.Replace("\r", "");
trim = trim.Replace("\n", "");
trim = trim.Replace("\t", "");
string str = trim;
string[] list = str.Split('|');
foreach (string s1 in list)
{
if (s1 != string.Empty)
{
dvProducts.RowFilter = "(CODE like '" + serachText + "*') AND (CODE <> '" + s1 + "')";
Session["ListViewItems"] = dvProducts;
}
}
ListView1.DataSource = dvProducts;
ListView1.DataBind();
}
DataView view = new DataView();
view.Table = DataSet1.Tables["Suppliers"];
view.RowFilter = "City = 'Berlin'";
view.RowStateFilter = DataViewRowState.ModifiedCurrent;
view.Sort = "CompanyName DESC";
// Simple-bind to a TextBox control
Text1.DataBindings.Add("Text", view, "CompanyName");

Eg:
Datatable newTable = new DataTable();
foreach(string s1 in list)
{
if (s1 != string.Empty) {
dvProducts.RowFilter = "(CODE like '" + serachText + "*') AND (CODE <> '" + s1 + "')";
foreach(DataRow dr in dvProducts.ToTable().Rows)
{
newTable.ImportRow(dr);
}
}
}
ListView1.DataSource = newTable;
ListView1.DataBind();
