多种控制类型

Question

用：SELECT ID，名称，标志1从表

是否有可能动态地显示任一按钮或基于标记1字段的比特值在一列中一个CheckBox ？

换句话说： 如果Flag1 = true，则将复选框显示为选中状态和只读状态。 如果Flag1 = false show click with click event并将行的id传递给handler。

我需要勾选哪个事件才能进行更改？数据绑定？ 如何设置.aspx或.cs中的复选框/按钮？通常我使用的ItemTemplate与GridView的...

  <asp:TemplateField HeaderText="Under Warranty" > 
      <ItemTemplate> 
       <asp:Button ID="WButton" runat="server" CommandName="AddWarrantyTrackerItem" CommandArgument = "<%# (Container.DataItemIndex) %>" Text="Track Warranty" Visible="false" /> 
       <asp:CheckBox ID="WFlag" runat="server" Visible="false" readonly="true" /> 
      </ItemTemplate> 
     </asp:TemplateField> 
     <asp:TemplateField HeaderText="Depot" > 
      <ItemTemplate> 
       <asp:Button ID="DButton" runat="server" CommandName="AddDepotTrackerItem" CommandArgument = "<%# (Container.DataItemIndex) %>" Text="Track Depot" Visible="false" /> 
       <asp:CheckBox ID="DFlag" runat="server" Visible="false" readonly="true" /> 
      </ItemTemplate> 
     </asp:TemplateField> 

代码隐藏：

protected void gridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.DataRow) 
    { 
     CheckBox WFlag = (CheckBox)e.Row.FindControl("WFlag"); 
     Button WButton = (Button)e.Row.FindControl("WButton"); 
     CheckBox DFlag = (CheckBox)e.Row.FindControl("DFlag"); 
     Button DButton = (Button)e.Row.FindControl("DButton"); 
     var record = (System.Data.Common.DbDataRecord)e.Row.DataItem; 
     bool flagW = (bool)record.GetValue(14); 
     bool flagD = (bool)record.GetValue(15); 
     int reqnum = (int)record.GetValue(0); 
     if (flagW == false) 
     { 
      WButton.Visible = true; 
      WFlag.Visible = false; 
     } 
     else 
     { 
      WButton.Visible = false; 
      WFlag.Visible = true; 
      WFlag.Checked = true; 
     } 
     if (flagD == false) 
     { 
      DButton.Visible = true; 
      DFlag.Visible = false; 
     } 
     else 
     { 
      DButton.Visible = false; 
      DFlag.Visible = true; 
      DFlag.Checked = true; 
     } 
    } 
}

是的，你可以使用一个TemplateField和RowDataBound切换可视性：

ASPX：

<Columns> 
    <asp:TemplateField HeaderText="Flagged"> 
     <ItemTemplate> 
      <asp:Button ID="ButtonFlag" runat="server" Text="flag it" Visible="true" /> 
      <asp:CheckBox ID="CheckFlag" runat="server" Checked="true" Visible="false" /> 
     </ItemTemplate> 
    </asp:TemplateField> 

Codebehind：

protected void gridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.DataRow) 
    { 
     CheckBox chkFlag = (CheckBox)e.Row.FindControl("CheckFlag"); 
     Button buttonFlag = (Button)e.Row.FindControl("ButtonFlag"); 
     DataRow row = ((DataRowView)e.Row.DataItem).Row; 
     bool flagged = row.Field<bool>("Flag1"); 
     buttonFlag.Visible = !flagged; 
     chkFlag.Visible = flagged; 
    } 
}
