在特定的GridView行中禁用/隐藏控件 [英] Disable/ Hide a control inside a specific row of GridView

问题描述

我有下面的代码来在asp.net和gridview内部创建一个gridview我有一个删除按钮。下面的代码工作正常，并显示在所有行中删除。
我想在第一行隐藏/禁用删除按钮。有人可以提供代码部分吗？

 < asp：gridview ID =Gridview1runat =server
 ShowFooter =trueAutoGenerateColumns =false> 
<列> 
< asp：BoundField DataField =RowNumberHeaderText =Row Number/> 
< asp：TemplateField HeaderText =Cat> 
< ItemTemplate> 
< asp：TextBox ID =TextBoxCatrunat =serverEnabled =false>< / asp：TextBox> 
< / ItemTemplate> 
< / asp：TemplateField> 
< asp：TemplateField HeaderText =Delete> 
< ItemTemplate> 
< asp：LinkBut​​ton ID =DeleteItemsGridRowButtonrunat =server>删除< / asp：LinkBut​​ton> 
< / ItemTemplate> 
< / asp：TemplateField> 
< /列> 
< / asp：gridview> 
  

解决方案

您可以使用 GridView.RowDataBound Event 事件。

然后使用 FindControl 方法找到 LinkBut​​ton 。

  public class Animal 
 {
 public int RowNumber {get;组; } 
 public string Name {get;组; } 
 
 $ b protected void Page_Load（object sender，EventArgs e）
 {
 if（！IsPostBack）
 {
 Gridview1.DataSource =新列表<动物> 
新的动物{RowNumber = 1，Name =One}，
新的动物{RowNumber = 2，Name =Two}，
 new Animal {RowNumber = 3，Name =Three}，
 new Animal {RowNumber = 4，Name =Four}，
}; 
 Gridview1.DataBind（）; 
} 
} 
 
 private int _counter; 
 
 protected void GridView1_RowDataBound（object sender，GridViewRowEventArgs e）
 {
 if（e.RowType == DataControlRowType.DataRow）
 {
 if （_counter == 0）
 {
 var linkBut​​ton = e.Row.FindControl（DeleteItemsGridRowButton）
作为LinkBut​​ton; 
 linkBut​​ton.Visible = false; 
 _counter ++; 
} 
} 
 
} 
  

I have below code to create a gridview in asp.net and inside gridview I have a delete button. Below code works fine and shows Delete in all rows. I want to hide/ Disable the Delete button in very first row. Can somebody suggest the code part?

<asp:gridview ID="Gridview1" runat="server" 
  ShowFooter="true" AutoGenerateColumns="false">
     <Columns>
            <asp:BoundField DataField="RowNumber" HeaderText="Row Number" />
                <asp:TemplateField HeaderText="Cat">
                <ItemTemplate>
                    <asp:TextBox ID="TextBoxCat" runat="server" Enabled="false"></asp:TextBox>
                </ItemTemplate>
            </asp:TemplateField>
              <asp:TemplateField HeaderText="Delete" >
                            <ItemTemplate>
                                <asp:LinkButton ID="DeleteItemsGridRowButton" runat="server">Delete</asp:LinkButton>
                            </ItemTemplate>
                        </asp:TemplateField>
            </Columns>
        </asp:gridview>

解决方案

You can use GridView.RowDataBound Event event.

Then find the LinkButton using FindControl method.

public class Animal
{
    public int RowNumber { get; set; }
    public string Name { get; set; }
}

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        Gridview1.DataSource = new List<Animal>
        {
            new Animal {RowNumber = 1, Name = "One"},
            new Animal {RowNumber = 2, Name = "Two"},
            new Animal {RowNumber = 3, Name = "Three"},
            new Animal {RowNumber = 4, Name = "Four"},
        };
        Gridview1.DataBind();
    }
}

private int _counter;

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if (_counter == 0)
        {
            var linkButton = e.Row.FindControl("DeleteItemsGridRowButton") 
                as LinkButton;
            linkButton.Visible = false;
            _counter++;
        }
    }

}
