添加在GridView的

Question

我加入列在最后一栏删除对grid-view dynamically

DataTable dt1 = new DataTable(); 
dt1.Columns.Add("Item Title", typeof(string)); 
dt1.Columns.Add("Unit Pack", typeof(string)); 
dt1.Columns.Add("Pack", typeof(string)); 
gv1.DataSource = dt1; 
gv1.DataBind(); 

按钮，并通过

<asp:GridView ID="gv" runat="server"> 
    <Columns> 
     <asp:CommandField ShowDeleteButton="true" /> 
    </Columns> 
</asp:GridView> 

添加delete button automatically这表明像

| Delete | Item Title | Unit Pack | Pack | 

在GridView现在我想在最后一列显示删除按钮，如

| Item Title | Unit Pack | Pack | Delete | 

我该怎么做？如何在最后一栏创建删除按钮？

Answer 1

<asp:GridView ID="gv" runat="server" AutoGenerateColumns="False"> 
    <Columns> 
     <asp:BoundField DataField="Item Title" HeaderText="Item Title" /> 
     <asp:BoundField DataField="Unit Pack" HeaderText="Unit Pack" /> 
     <asp:BoundField DataField="Pack" HeaderText="Pack" /> 
     <asp:CommandField ShowDeleteButton="true" /> 
    </Columns> 
</asp:GridView>\ 

和代码的背景是：

dt1.Columns.Add("Item Title", typeof(string)); 
dt1.Columns.Add("Unit Pack", typeof(string)); 
dt1.Columns.Add("Pack", typeof(string)); 
gv1.DataSource = dt1; 
gv1.DataBind(); 

试试这个代码

你加入柱动态这就是为什么你需要添加删除列的动态。或者你可以在的RowDataBound添加的LinkBut​​ton：

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
if (e.Row.DataItem != null) 
{ 
    LinkButton lb = new LinkButton(); 
    lb.CommandArgument = e.Row.Cells[3].Text; 
    lb.CommandName = "Delete"; 
    lb.Text = "Delete"; 

    e.Row.Cells[3].Controls.Add((Control)lb); 
} 
} 

在rowCommand

您可以删除写代码：

protected void gv_RowCommand(object sender, CommandEventArgs e) 
{ 
switch (e.CommandName.ToLower()) 
{ 
    case "delete": 
//your code here 
     break; 
    default: 
     break; 
} 
}

在GridView的RowCreated事件，你可以把CommandField中向右：

protected void gv1_RowCreated(object sender, GridViewRowEventArgs e) 
{ 
    GridViewRow row = e.Row; 

    TableCell cell = row.Cells[0]; 
    row.Cells.Remove(cell);     
    row.Cells.Add(cell); 
}
