Datagridview单元格验证错误标志符号 [英] Datagridview cell validating error glyph

问题描述

如果我设置了e.cancel = true 并且设置为

，那么

在我的一个窗体上进行单元格验证事件取决于标准，该字段不会跳转提前 但错误字形未显示

表单框架4.5.2

甚至 

< ; appSettings>

  &NBSP; < add key =" EnableWindowsFormsHighDpiAutoResizing"值= QUOT;真" />

< / appSettings>

已添加到app.config

errorprovider控件已添加到表单

请看一下屏幕截图

你能猜出为什么没有显示错误字形

 private void dgvtest_CellValidating（object sender，DataGridViewCellValidatingEventArgs e） 
 {
 if（e.RowIndex == -1）
 return; 
 string clmname = dgvtest.Columns [e.ColumnIndex] .Name; 
 if（clmname.Equals（" test1"））
 {
 if（e.FormattedValue.ToString（）。Equals（" Stop"））
 {
 dgvtest [clmname，e.RowIndex] .ErrorText =" Test Erro" ;; 
 e.Cancel = true; 
返回; 
} 
} 
 
}

on my one of windows form for cell validating event depending upon the criteria if i set e.cancel = true  and set as under

the field does not jump ahead  but the error glyph is not shown

the form framework 4.5.2

even the 

<appSettings>
    <add key="EnableWindowsFormsHighDpiAutoResizing" value="true" />

</appSettings>

is added to app.config

errorprovider control is added to form

 private void dgvtest_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
        {
            if (e.RowIndex == -1)
                return;
            string clmname = dgvtest.Columns[e.ColumnIndex].Name;
            if (clmname.Equals("test1"))
            {
                if (e.FormattedValue.ToString().Equals("Stop"))
                {
                    dgvtest[clmname, e.RowIndex].ErrorText = "Test Erro";
                    e.Cancel = true;
