推荐答案

BoundField

如果您使用 BoundField ，则下面的内容会起作用。

BoundField

Something like below would work, if you have used BoundField.

private void GridImport_RowDataBound(Object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if (e.Row.Cells[2].Text.Equals("D"))
            e.Row.Visible = false;
    }
}

TemplateField

如果值在<$ c内$ c> TemplateField ，然后你需要找到那个控件，然后尝试比较文本......假设里面有一个 TextBox code> TemplateField ，其中值已固定。

TemplateField

If the value is inside a TemplateField, then you need to find that control and then try to compare the text like... Suppose there is a TextBox inside TemplateField, where the value is fastened.

private void GridImport_RowDataBound(Object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        TextBox txtStatus = (TextBox)rw.FindControl("txStatus");
        
        if (txtStatus.Text.Equals("D"))
            e.Row.Visible = false;
}

GridImport.DataSource = dtTemSec.AsEnumerable()
                                .Where(x => x.Field<string>("Status") != "D")
                                .CopyToDataTable();
GridImport.DataBind();
