Gridview标题背景颜色在PDF中不变

我正在将多个gridview导出为PDF，我想为网格标题着色。我尝试在Html页面和代码后面但它没有正常工作的颜色和字体正在改变，除了这种背景颜色。





我这样工作

< asp：GridView ID =DataListStatenamerunat =serverWidth =100％ EmptyDataText =未找到记录AutoGenerateColumns =falseShowHeader =true>

< headerstyle backcolor =＃C0C0C0

forecolor =MediumBlue/ >

< columns> < asp：BoundField DataField =VERSIONSHeaderText =VERSIONSVisible =false/>

< asp：BoundField DataField =COM_NAMEHeaderText =COMPONENT NAME/>

< asp：BoundField DataField =INITIALIZED_DATEHeaderText =INITIATED DATE/>

< asp：BoundField DataField =PDV_NEW_MATERIAL_CODEHeaderText =NEW MATERIAL代码/>

< asp：BoundField DataField =PDV_OLD_MATERIAL_CODEHeaderText =旧材料代码/>

< asp：BoundField DataField =PDV_FINALIZED_DATE HeaderText =FINALIZED DATE/>

< asp：BoundField DataField =STATUSHeaderText =STATUS/>









DataListStatename.DataSource = dt1.Tables [0];

DataListStatename.DataBind（） ;

DataListStatename.HeaderStyle.BackColor = Color.Green; //这不起作用

// DataListStatename.HeaderStyle.ForeColor = Color.Green; //这个工作正常

// DataListStatename.Style.Add（font-size，40px）; //这是工作ng $>
DataListProductInformation.DataSource = dt1.Tables [7];

DataListProductInformation.DataBind（）;



result =（

艺术品历史

< asp：image ID ='Image1'ImageUrl ='〜/ Images / Goose Logo1.png'runat ='server'>

）;

hw.Write（result）;

bindpdf.RenderControl（hw）;



// hw.Write（）;

StringReader sr = new StringReader （sw.ToString（））;

文档pdfDoc =新文档（PageSize.A4,10f，10f，10f，0f）;

HTMLWorker htmlparser = new HTMLWorker（pdfDoc ）;

PdfWriter.GetInstance（pdfDoc，Response.OutputStream）;

pdfDoc.Open（）;

htmlparser.Parse（sr）;

pdfDoc.Close（）;

Response.Write（pdfDoc）;

Response.End（）;

}
