我有gridview,其中包含复选框作为templatefield。我已经尝试过如此努力,但我仍然无法获得所需的结果,即如果选中复选框,则执行操作-1,否则执行操作-2,但每次执行操作-2时。以下是我的代码,我需要你的帮助。
Gridview代码:
<asp:GridView ID="final" runat="server" AutoGenerateColumns="False";>
<Columns>
<asp:BoundField DataField="name" HeaderText="Employee Name" SortExpression="date" />
<asp:BoundField DataField="ldate" HeaderText="Date Of Leave" SortExpression="ldate"
/>
<asp:TemplateField HeaderText="Half/Full">
<ItemTemplate>
<asp:RadioButtonList ID="RadioButtonList1" runat="server">
<asp:ListItem Enabled="true" Value="Half">Half</asp:ListItem>
<asp:ListItem Enabled="true" Value="Full">Full</asp:ListItem>
</asp:RadioButtonList>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Approve">
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
我已经检查了收音机和复选框的代码:
DataTable dtable = new DataTable();
dtable.Columns.Add(new DataColumn("Date", typeof(DateTime)));
dtable.Columns.Add(new DataColumn("Half/Full", typeof(float)));
dtable.Columns.Add(new DataColumn("Status", typeof(string)));
Session["dt"] = dtable;
SqlConnection conn = new SqlConnection();
conn.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["leave"].ConnectionString;
conn.Open();
foreach (GridViewRow gvrow in final.Rows)
{
dtable=(DataTable)Session["dt"];
CheckBox chk = (CheckBox)gvrow.FindControl("CheckBox1");
if (chk != null & chk.Checked)
{
RadioButtonList rButton = (RadioButtonList)gvrow.FindControl("RadioButtonList1");
if (rButton.SelectedValue == "Half")
{
//perform action-1
}
else
{
//perform action-1
}
}
else
{
perform action-2
}
}
每次进入最后的其他地方......为什么?
答案 0 :(得分:4)
使用逻辑和运算符&&
代替按位&
运算符来组合if语句中的条件。
更改
if (chk != null & chk.Checked)
到的
if (chk != null && chk.Checked)
根据OP的评论修改
您需要检查绑定网格的方式,使其在回发时没有绑定。
if(!Page.IsPostBack)
{
//bind here
}

确保您在页面加载时没有再次绑定gridview,如果您那么必须应用IsPostback检查
答案 2 :(得分:0)
试试这个
<asp:CheckBox ID="CheckBox1" runat="server" OnCheckedChanged="CheckBox1_CheckedChanged" AutoPostBack="true"/>
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
CheckBox chk = (CheckBox)sender;
GridViewRow gr = (GridViewRow)chk.Parent.Parent;
RadioButtonList RadioButtonList1 = (RadioButtonList)gr.FindControl("RadioButtonList1");
if (RadioButtonList1 != null)
{
RadioButtonList1.Items.FindByText("Full").Selected = true;
}
}
