[英]Align text CENTER when exporting to excel
我正在使用下面的兩個函數將我的gridview數據導出到excel。問題是,數據已完全導出但已正確對齊,我需要將其居中對齊,但我無法弄清楚。 。任何幫助將不勝感激。
public static void GenerateExcel(GridView gv)
{
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AppendHeader("Content-disposition", "attachment; filename=Leave_Report.xls");
HttpContext.Current.Response.ContentType = "application/ms-excel";
using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter htw = new HtmlTextWriter(sw))
{
// Create a table to contain the grid
Table table = new Table();
// include the gridline settings
table.GridLines = gv.GridLines;
// add the header row to the table
if (gv.HeaderRow != null)
{
PrepareControlForExport(gv.HeaderRow);
table.Rows.Add(gv.HeaderRow);
}
//Make Header Coloruful
for (int j = 0; j < gv.Columns.Count; j++)
{
//Apply style to Individual Cells
gv.HeaderRow.Cells[j].Style.Add("background-color", "#4DB4EE");
}
// add each of the data rows to the table
foreach (GridViewRow row in gv.Rows)
{
PrepareControlForExport(row);
table.Rows.Add(row);
}
// add the footer row to the table
if (gv.FooterRow != null)
{
PrepareControlForExport(gv.FooterRow);
table.Rows.Add(gv.FooterRow);
}
// render the table into the htmlwriter
table.RenderControl(htw);
// render the htmlwriter into the response
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
}
}
}
private static void PrepareControlForExport(Control control)
{
for (int i = 0; i < control.Controls.Count; i++)
{
Control current = control.Controls[i];
if (current is LinkButton)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as LinkButton).Text));
}
else if (current is ImageButton)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as ImageButton).AlternateText));
}
else if (current is HyperLink)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as HyperLink).Text));
}
else if (current is DropDownList)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as DropDownList).SelectedItem.Text));
}
else if (current is CheckBox)
{
control.Controls.Remove(current);
control.Controls.AddAt(i, new LiteralControl((current as CheckBox).Checked ? "True" : "False"));
}
if (current.HasControls())
{
PrepareControlForExport(current);
}
}
}
嘗試
wSheet.get_Range("B3", "B3").HorizontalAlignment = HorizontalAlign.Center;
代替
wSheet.get_Range("B3", "B3").HorizontalAlignment = Constants.xlCenter;
嘗試這個
foreach (GridViewRow row in gv.Rows)
{
foreach (TableCell cell in row.Cells)
{
cell.Attributes.CssStyle["text-align"] = "center";
}
}
