如何在GridView的命令字段控件中禁用控件 [英] How to disable a control in command field control in gridview

问题描述

如何在gridview中找到命令字段控件.

how to find a command field control in the gridview.

在未绑定行数据的方法中.

in a method not in the row data bound.

到目前为止，我已经使用了这种编码，但是找不到控件.

so far i have used this coding but i cant find the control.

<asp:CommandField ButtonType="Image" ShowEditButton="True
                  HeaderText="Enter Leave"
                  EditImageUrl="~/IMAGES/edit-icon.gif">
    <ItemStyle HorizontalAlign="Center" />
</asp:CommandField>

源代码:

ImageButton edit = (ImageButton)EmployeeDetails.FindControl("Image");
edit.Enabled = false;

推荐答案

您可以通过以下方式禁用列本身，

You can disable column itself with,

GridView1.AutoGenerateEditButton = false;

来自页面后面的代码.

或者您可以使用ItemTemplate代替CommandField，

Or you can use ItemTemplate instead of CommandField,

<asp:TemplateField>
    <ItemTemplate>
        <asp:LinkButton runat="server" ID="id" CommandName="Edit" Text="Edit" />
    </ItemTemplate>
</asp:TemplateField>

在后面的代码中，您可以遍历GridView的行并禁用每个LinkBut​​ton.

And at code behind you can iterate through rows of GridView and disable each LinkButton.

foreach(GridViewRow gvr in GridView1.Rows)
{
    LinkButton row = gvr.FindControl("id") as LinkButton;
    row.Enabled = false;
}

首次

我尝试了第二种解决方案，并且有效.但是，在使用 foreach 之前，请确保已填充 GridView .否则， GridView.Rows.Count 可能为0.

I tried my second solution and it works. However, make sure your GridView is filled before you use foreach. Otherwise, GridView.Rows.Count would probably be 0.

第二次修改:

这也适用于 CommandField .在您的 GridView 中，将 CommandField 的位置替换为0.

This works for CommandField too. Replace 0 with the location of CommandField in your GridView.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{        
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
         e.Row.Cells[0].Enabled = false;
    }
}
