Hi , i have a dropdownlist ,txtbox and a gridview.The dynamic data's are binded to it.I want to add a static value to the dropdownlist like "select" so that if i click on that select i should get all the values in gridview.i.e.,even if the textbox is empty and dropdownlist==select the gridview values must be displayed.

The functionality is :
1.wen values are entered in textbox the gridview is binded according to it and also the ddl will b displayed according to the textbox value
2.ddl will also work according to it.and ddl maintains the same value after postback.

But currently my problem is if i click on the "select option" in ddl nothin gets displayed in the gridview .but i want gridview values to be displayed for ddl="select"(static value).

how to bind the static value to the gridview ?ur answers are welcomed..

DataView dvtxtfullname = new DataView((DataTable)Session["GrdSearch"]);
StringBuilder filter = new StringBuilder();
filter.Append("fullname like '%" + Convert.ToString(txtfullname.Text) + "%'");
dvtxtfullname.RowFilter = filter.ToString();
ddlCountries.DataSource = dvtxtfullname.ToTable(true, "Country");
ddlCountries.DataTextField = "Country";
ddlCountries.DataBind();
ddlCountries.Items.Insert(0, new System.Web.UI.WebControls.ListItem("Select country", ""));

DataView dvgrid = new DataView((DataTable)Session["GrdSearch"]);

if (!string.IsNullOrEmpty(ddlCountries.SelectedValue))
{
filter.Append(" Country='" + Convert.ToString(ddlCountries.SelectedItem) + "'");

}

dvgrid.RowFilter = filter.ToString();
grdSearch.DataSource = dvgrid;
grdSearch.DataBind();

if (Session["ddlvalue"] != null)
{
ddlCountries.SelectedValue = Session["ddlvalue"].ToString();
dvtxtfullname.RowFilter = "Country='" + ddlCountries.SelectedItem + "' AND fullname like '%" + Convert.ToString(txtfullname.Text) + "%'";
grdSearch.DataSource = dvtxtfullname;
grdSearch.DataBind();
}

}

protected void ddlCountries_SelectedIndexChanged(object sender, EventArgs e)
{
DataTable dtCountries = (DataTable)Session["GrdSearch"];
DataView dv = new DataView(dtCountries);
dv.RowFilter = "Country='" + ddlCountries.SelectedItem + "' AND fullname like '%" + Convert.ToString(txtfullname.Text) + "%'";
grdSearch.DataSource = dv;
