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 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();
