C# Gridview单击标题进行排序触发行命令
我有一个相当简单的GridView。这是列的标记:C# Gridview单击标题进行排序触发行命令,c#,asp.net,.net,asp.net-4.0,C#,Asp.net,.net,Asp.net 4.0,我有一个相当简单的GridView。这是列的标记: <Columns> <asp:TemplateField HeaderText="JD Name" SortExpression="FullName" HeaderStyle-HorizontalAlign="Center" ItemStyle-Width="180px" > <ItemTemplate
<Columns>
<asp:TemplateField HeaderText="JD Name" SortExpression="FullName"
HeaderStyle-HorizontalAlign="Center" ItemStyle-Width="180px" >
<ItemTemplate>
<asp:LinkButton CommandName="edt" CommandArgument='<%#Eval("JurisdictionID") %>' runat="server" Text='<%#Eval("FullName") %>' />

<asp:BoundField HeaderText="JD Abbreviation" ItemStyle-Width="200px" DataField="JDAbbreviation" SortExpression="JDAbbreviation"

然而,当我点击一个列进行排序时,它首先触发一个row命令事件,然后触发排序事件。有人能告诉我我犯了什么错误吗?在RowCommand参数中,我得到SortExpression。这对我来说真的很有趣
排序
是一个行命令
。查看此MSDN以了解更多详细信息
在row命令事件中,您应该添加一个if
语句,以便确定row命令代码应该在何时执行。使用e.CommandName
void ContactsGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
// If multiple buttons are used in a GridView control, use the
// CommandName property to determine which button was clicked.
if(e.CommandName=="Add")
{
// Convert the row index stored in the CommandArgument
// property to an Integer.
int index = Convert.ToInt32(e.CommandArgument);
// Retrieve the row that contains the button clicked
// by the user from the Rows collection.
GridViewRow row = ContactsGridView.Rows[index];
// Create a new ListItem object for the contact in the row.
ListItem item = new ListItem();
item.Text = Server.HtmlDecode(row.Cells[2].Text) + " " +
Server.HtmlDecode(row.Cells[3].Text);
// If the contact is not already in the ListBox, add the ListItem
// object to the Items collection of the ListBox control.
if (!ContactsListBox.Items.Contains(item))
{
ContactsListBox.Items.Add(item);
}
}
}
