和一个添加按钮，仅使用表格或网格添加设计页面中的字段。如果我点击另一个按钮，即所有行创建的保存按钮应该存储在sql server 2005中..

这里我的代码是

I need to add three fields which of ( country name,language name and description )..
and a "add button" to add the fields in design page only using table or grid.If i click another button i.e "save button" that all the rows created are should be stored in sql server 2005..

I had made 30% of it now i can add a single row.if i tried to add multiple row it's overriding.I can able identify the reason but unable to solve.. Plz help me to complete this process...

{
DataTable dt = new DataTable();

DataColumn[] columns = { new DataColumn("Country", System.Type.GetType("System.String")), new DataColumn("Language", System.Type.GetType("System.String")), new DataColumn("Description", System.Type.GetType("System.String")) };

        dt.Columns.AddRange(columns);
        DataRow dr;

        dr = dt.NewRow();
        dr[0] = ddlCountry.SelectedValue;
        dr[1] = ddlLanguage.SelectedValue;
        dr[2] = txtDescription.Text;
        dt.Rows.Add(dr);

推荐答案

protected void lnkbtnAddRow_Click(object sender, EventArgs e)
{
if(Session["Data"]==null)
{
DataTable dt = new DataTable();
 
DataColumn[] columns = { new DataColumn("Country", System.Type.GetType("System.String")), new DataColumn("Language", System.Type.GetType("System.String")), new DataColumn("Description", System.Type.GetType("System.String")) };
dt.Columns.AddRange(columns);
}
else
{
 DataTable dt=(DataTable)Session["Data"];
}
 
        
        DataRow dr;
 
        dr = dt.NewRow();
        dr[0] = ddlCountry.SelectedValue;
        dr[1] = ddlLanguage.SelectedValue;
        dr[2] = txtDescription.Text;
        dt.Rows.Add(dr);
        Session["Data"]=dt;
        GVaddrow.DataSource = dt;
        GVaddrow.DataBind();
}

尝试这个...它应该有用...
