C# 对于每个gridview行，commandfield edit启用true或false

这里是我的代码，但全部在编辑列中启用了false，我希望false编辑按钮取决于状态值

foreach (GridViewRow row in GridView1.Rows)
{
    statuse = dt.Rows[0].ItemArray[6].ToString();
    if (statuse != null || statuse != "")
    {
        if (control is LinkButton)
        {
            LinkButton btn = control as LinkButton;
            btn.Enabled = btn.CommandName.Equals("Edit");
            btn.Enabled = false;
        }
    }
}

                <asp:TemplateField HeaderText = "No" ItemStyle-Width="50"  ItemStyle-HorizontalAlign="Center">
    <ItemTemplate>
        <asp:Label ID="lblRowNumberA" runat="server" />
    </ItemTemplate>
</asp:TemplateField>

<asp:BoundField DataField="ProposedBy" HeaderText="Proposer"  ReadOnly="true"
            ItemStyle-Width="10%" />

        <asp:BoundField DataField="Date" HeaderText="Date" dataformatstring="{0:d}"
           ItemStyle-Width="100px" ReadOnly="True" />


        <asp:TemplateField HeaderText="Note" ItemStyle-Width="70%" ItemStyle-HorizontalAlign="Left">
           <ItemTemplate>
           <asp:Label ID="Label1ert" runat="server" Text='<%#Bind("Note") %>'></asp:Label>
           </ItemTemplate>
           <EditItemTemplate>
           <asp:TextBox ID="TextBox1edit" runat="server" TextMode="MultiLine" Text='<%#Bind("Note") %>' ></asp:TextBox>
           </EditItemTemplate>

在RowDataBound事件中通常是这样做的

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    //check if the row is a datarow
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //cast the dataitem back to a row
        DataRowView row = e.Row.DataItem as DataRowView;

        //find the edit button in the row with findcontrol
        LinkButton btn = e.Row.FindControl("EditButtonID") as LinkButton;

        //check the status of the correct data field and set the button properties
        if (row["statuse"].ToString() == "Closed")
        {
            btn.Enabled = false;
        }
        else
        {
            btn.Enabled = true;
        }
    }
}

                <asp:TemplateField HeaderText = "No" ItemStyle-Width="50"  ItemStyle-HorizontalAlign="Center">
    <ItemTemplate>
        <asp:Label ID="lblRowNumberA" runat="server" />

</asp:TemplateField>

<asp:BoundField DataField="ProposedBy" HeaderText="Proposer"  ReadOnly="true"
            ItemStyle-Width="10%" />

        <asp:BoundField DataField="Date" HeaderText="Date" dataformatstring="{0:d}"
           ItemStyle-Width="100px" ReadOnly="True" />


        <asp:TemplateField HeaderText="Note" ItemStyle-Width="70%" ItemStyle-HorizontalAlign="Left">

如果编辑按钮是自动生成的，则必须根据列索引查找链接按钮

LinkButton btn = e.Row.Cells[i].Controls[0] as LinkButton;

        <asp:BoundField DataField="Date" HeaderText="Date" dataformatstring="{0:d}"
           ItemStyle-Width="100px" ReadOnly="True" />


        <asp:TemplateField HeaderText="Note" ItemStyle-Width="70%" ItemStyle-HorizontalAlign="Left">

对
不

您在找这个吗

btn.Enabled=statuse==null | | statuse==“”

我将为此使用RowDataBound事件。是的，我将使用RowDataBound。我在寻找：如果status value=“”，那么commandfieled enabled false。但是在我尝试之后，所有的命令编辑都变成了false，其中status已经或者没有更新我的答案。如果编辑按钮位于第一列，

i

将是

0

对象引用，但未设置为对象的实例。更新我的答案：LinkButton cmdField=e.Row.Cells[9]。控件[0]为LinkButton；cmdField.Visible=false；-->错误，则该列中没有控件。请注意，索引是从零开始的。也许发布你的gridview布局
