Adding Dynamic Menus from a Database

Opening a PDF file from ASP.Net

Use this single line of Code instead of going for Process to start Adobe Reader. This opens in a New Tab or in new window leaving your existing project to work.

ScriptManager.RegisterStartupScript(this, this.GetType(), "", "window.open('../PDF/Sample.pdf','_blank');", true);

Creating a PDF from Asp.Net

We need to have IText Sharp dll for this Code to work.. You can make a search in Google to get the Dll file. And after importing the dll you can use this code to create a PDF in specified path.

protected void btnPDF_Click(object sender, EventArgs e)
{
//ScriptManager.RegisterStartupScript(this, this.GetType(), "", "window.open('../PDFTest.aspx?PDFUrl=StatusLog.pdf','_blank');", true);


Response.Write("");
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=StatusLog.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
grdStatus.AllowPaging = false;
grdStatus.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(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();
}

To get the Grid Edit Index from a Template column Event

protected void imgButton_Click(object sender, ImageClickEventArgs e)
{
ImageButton imgBtn = (ImageButton)sender;
GridViewRow row = (GridViewRow)imgBtn.NamingContainer;
ScriptManager.RegisterStartupScript(this, this.GetType(), "", "Selected Index Is: " + grdRequests.Rows[row.RowIndex].Cells[1].Text.ToString() + ", true);
}

How can I show vertical text in the cell?

void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)

{

if (e.ColumnIndex == 0 && e.RowIndex > -1 && e.Value != null)

{

e.Paint(e.CellBounds, DataGridViewPaintParts.All

& ~DataGridViewPaintParts.ContentForeground);

StringFormat sf = new StringFormat();

sf.Alignment = StringAlignment.Center;

sf.LineAlignment = StringAlignment.Center;

sf.FormatFlags = StringFormatFlags.DirectionVertical;

e.Graphics.DrawString(e.Value.ToString(), e.CellStyle.Font,

new SolidBrush(e.CellStyle.ForeColor), e.CellBounds, sf);

e.Handled = true;

}

}
