我是 .NET 的新手,我的复选框有问题。即使它们被选中,它们都返回 false。这是我的asp代码
<asp:GridView ID="gvGeneros1" runat="server" class="divTable"
AutoGenerateColumns="False" DataKeyNames="idgenero" CssClass="table">
<Columns>
<asp:BoundField DataField="nome" HeaderText="Gênero" SortExpression="nome" >
<ControlStyle Width="200px" />
<ItemStyle Width="200px" />
</asp:BoundField>
<asp:TemplateField AccessibleHeaderText="Check">
<ItemTemplate>
<asp:CheckBox ID="checkGenero" runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
这是我的 C# 代码
DataSet dsDivided;
protected void Page_Load(object sender, EventArgs e)
{
Music musicbll = new Music();
DataSet dsGeneros = musicbll.getGenders();
int size = dsGeneros.Tables[0].Rows.Count;
dsDivided = null;
// Divide in two DataTable
dsDivided = Tools.SplitDataTableInTwo((DataTable)dsGeneros.Tables[0], size / 2);
gvGeneros1.DataSource = dsDivided.Tables["FirstSet"];
gvGeneros1.DataBind();
for (int i = 0; i < gvGeneros1.Rows.Count; i++)
{
((CheckBox)gvGeneros1.Rows[i].Cells[1].Controls[1]).Checked=false;
}
}
protected void btGravarPrefs_Click(object sender, EventArgs e)
{
DataTable dt = new DataTable("generos");
dt.Columns.Add("idgenero", typeof(int));
dt.Columns.Add("active", typeof(bool));
for (int i = 0; i < gvGeneros1.Rows.Count; i++)
{
int idCliente = (int)dsDivided.Tables[0].Rows[i][0];
bool check = ((CheckBox)gvGeneros1.Rows[i].Cells[1].Controls[1]).Checked; //always false
dt.Rows.Add(new object[] { idCliente, check});
}
}
}
我不知道该尝试更多,我到处搜索,似乎是正确的。谢谢
