Question

这里是我的代码，但是所有编辑列都启用了false，我希望false editbutton依赖于statuse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;
        }
    }
}

Answer 1

这通常是在RowDataBound事件中完成的。

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;
        }
    }
}

更新

如果自动生成编辑按钮，则必须根据列索引找到LinkButton。

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

     <asp:CommandField  ButtonType="Link" ShowEditButton="true" ItemStyle-Width="100px" />

    </Columns>

foreach gridview row，commandfield edit启用true或false
