我有一个包含三列员工姓名员工详细信息和员工年龄的网格视图。我想在每一行添加一个复选框,在选择每个复选框后,我想触发与该员工关联的插入查询。你能告诉我如何将这个动态功能添加到网格视图中吗?
另外,如果我们使用<%# EVAL %>
我不知道如何使用复选框来实现它。
ASPX:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="name" HeaderText="name" SortExpression="name" />
<asp:BoundField DataField="details" HeaderText="details"
SortExpression="details" />
<asp:BoundField DataField="age" HeaderText="age" SortExpression="age" />
</Columns>
</asp:GridView>
<br />
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="OK" />
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:connApps %>"
SelectCommand="SELECT [name], [details], [age] FROM [tblA]">
</asp:SqlDataSource>
<br />
<asp:Label ID="Label1" runat="server"></asp:Label>
后面的代码:
protected void Button1_Click(object sender, EventArgs e)
{
Label1.Text = "Selected item name:<br>";
foreach (GridViewRow item in GridView1.Rows)
{
CheckBox chk = (CheckBox)item.FindControl("CheckBox1");
if (chk != null)
{
if (chk.Checked)
{
Label1.Text += item.Cells[1].Text + "<br>";
}
}
}
}
输出:
您可以将 TemplateFields 用于 GridView:
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField >
<ItemTemplate>
<asp:CheckBox ID="myCheckBox" runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
并在代码后面使用下面的代码:
ClusterName = GV.Rows(1).Cells(2).FindControl("myLabelinTheGridViewTemplateField")
这是一个例子,
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
BackColor="White" BorderColor="#336699" BorderStyle="Solid" BorderWidth="1px"
CellPadding="0" CellSpacing="0" DataKeyNames="CategoryID" Font-Size="10"
Font-Names="Arial" GridLines="Vertical" Width="40%">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkStatus" runat="server"
AutoPostBack="true" OnCheckedChanged="chkStatus_OnCheckedChanged"
Checked='<%# Convert.ToBoolean(Eval("Approved")) %>'
Text='<%# Eval("Approved").ToString().Equals("True") ? " Approved " : " Not Approved " %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="CategoryID" HeaderText="CategoryID" />
<asp:BoundField DataField="CategoryName" HeaderText="CategoryName" />
</Columns>
<HeaderStyle BackColor="#336699" ForeColor="White" Height="20" />
