在项目模板中禁用图像按钮

Question

如何禁用/隐藏项目模板内部的按钮？我想在加载时隐藏保存按钮，然后显示它并在单击编辑按钮时隐藏编辑按钮。

模板：

<asp:TemplateField ShowHeader="False"> 
    <ItemTemplate> 
    <asp:ImageButton ID="ImageButtonEdit" runat="server" CommandName="Edit" ImageUrl="loginstyling/images/Edit.png" Visible="true" /> 
    <asp:ImageButton ID="ImageButtonUpdate" runat="server" CommandName="Update" ImageUrl="loginstyling/images/Save.png" Visible="true" OnClick="ImageButtonUpdate_Click" /> 
    <asp:ImageButton ID="ImageButtonDelete" runat="server" CommandName="Delete" ImageUrl="loginstyling/images/Remove.png"/> 
    </ItemTemplate> 
</asp:TemplateField> 

背后：

 private void ImageButtonUpdate_Click(object sender, EventArgs e) 
    { 
     ImageButtonUpdate.Enabled = false; // not working, dosnt find the button 
    } 

Answer 1

使用事件的sender

protected void ImageButtonUpdate_Click(object sender, EventArgs e){ 
    ImageButton btnupdate= sender as ImageButton; 
    btnupdate.Enabled = false; 
    //if you need to get other controls in the same row 
    GridViewRow row = (GridViewRow)btnupdate.NamingContainer; 
    var btnedit= (ImageButton)row.FindControl("ImageButtonEdit"); 
    btnedit.Enabled = false; // do enable or disable as you need 
} 

Answer 2

您需要检索的ImageButton如下，因为它是居住在GridView

private void ImageButtonUpdate_Click(object sender, EventArgs e) 
{ 
    //Get the ImageButton that raised the event 
    ImageButton btn = (ImageButton)sender; 
    btn .Enabled = false; 
} 

编辑

步骤1

为Update提供相同onClick事件和Edit即

OnClick="ImageButtonUpdate_Click" 

步骤2

使用CommandName属性

 ImageButton btn = (ImageButton)sender; 
     if(btn.CommandName =="Update") 
     { 
      btn.Enabled = false; 
     } 
     if(btn.CommandName =="Edit") 
     { 
      btn.Enabled = false; 
     }
