我有一个从数据库填充的gridview,我想允许用户编辑并添加到gridview。完成更改/添加后,将其提交到数据库。有人可以帮我怎么做吗?
这是我目前的代码
<asp:GridView ID="Grd" runat="server" AutoGenerateColumns="False" OnRowEditing="Grds_RowEditing"
OnRowCancelingEdit="Grd_RowCancelingEdit" OnRowUpdating="Grd_RowUpdating" Width="500px">
<Columns>
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:HiddenField ID="NameID" runat="server" Value='<%# Bind("ID")%>' />
<asp:Label ID="LblName" runat="server" Text='<%# Bind("Name")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Date">
<EditItemTemplate>
<asp:TextBox ID="TxtDate" runat="server" Text='<%# Bind("Date") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="LblDate" runat="server" Text='<%# Bind("Date")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField ShowEditButton="True" />
<asp:CommandField ShowDeleteButton="True" />
</Columns>
</asp:GridView><asp:Button ID="btnok" Text="OK" Height="25" Width="25" runat="server" />
和背后的代码
protected void Page_Load(object sender, EventArgs e)
{
BindGrid(int.Parse(hfID.Value));
}
protected void BindGrid(int iPerson)
{
DataContext dc = new DataContext(ConfigurationManager.ConnectionStrings["DB"].ConnectionString);
var qry = from p in dc.GetDetails(iPerson)
select p;
Grd.DataSource = qry;
Grd.DataBind();
}
protected void Grd_RowEditing(object sender, GridViewEditEventArgs e)
{
Grd.EditIndex = e.NewEditIndex;
//Bind data to the GridView control.
BindGrid(int.Parse(hfID.Value));
}
protected void Grd_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
Grd.EditIndex = -1;
BindGrid(int.Parse(hfID.Value));
}
protected void Grd_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
}
protected void btOK_Click(object sender, EventArgs e)
{
//update the database with changes
}

在按钮单击中尝试此操作, dtCurrentTable 是您的gridview绑定数据表。
int rowIndex = 0;
StringCollection sc = new StringCollection();
for (int i = 1; i <= dtCurrentTable.Count; i++)
{
//extract the TextBox values
Label box1 = (Label)GridView2.Rows[rowIndex].Cells[0].FindControl("lblbedroom");
DropDownList box2 = (DropDownList)GridView2.Rows[rowIndex].Cells[0].FindControl("ddpAccomodates");
DropDownList box3 = (DropDownList)GridView2.Rows[rowIndex].Cells[0].FindControl("ddpBathroom");
DropDownList box4 = (DropDownList)GridView2.Rows[rowIndex].Cells[0].FindControl("ddpBedType");
TextBox box5 = (TextBox)GridView2.Rows[rowIndex].Cells[0].FindControl("txtPrices");
DropDownList box6 = (DropDownList)GridView2.Rows[rowIndex].Cells[0].FindControl("ddpMiniStay");
//get the values from the TextBoxes
//then add it to the collections with a comma "," as the delimited values
sc.Add("Private Room" + box1.Text + "," + box2.SelectedItem.Value + "," + box3.SelectedItem.Value + "," + box4.SelectedItem.Value + "," + box5.Text + "," + box6.SelectedItem.Value);
rowIndex++;
}
InsertToDb(sc);
然后
private void InsertToDb(StringCollection sc)
{
string[] splitItems = null;
foreach (string item in sc)
{
//split and save in to db here
}
}
