Here is what you can do. Before you bind your grid (on page load, or whenever) store you dataTable in viewstate.

//In page load<br />
ViewState["yourDataTable"] = dt;<br />
<br />
<br />
 private void Addrow()<br />
{<br />
DataTable dt = (DataTable)ViewState["yourDataTable"];<br />
<br />
 int row = 0;<br />
<br />
            while (row < dt.Rows.Count)<br />
            {<br />
<br />
                TextBox txt = (TextBox)this.GridView.Items[row].FindControl("txt");<br />
dt.Rows[row]["txtValue"] = txt.Text;<br />
                <br />
<br />
                row += 1;<br />
            }<br />
<br />
 DataRow dr;<br />
dr = dt.NewRow();<br />
dt.Rows.Add(dr);<br />
<br />
<br />
 dg.DataSource = dt;<br />
dg.DataBind();

Problem with Health Monitoring (asp.net c# web app)

Hi,

I am new to the built in health monitoring functionality that comes built into the .net framework. I have followed a v.good video tutorial and I cant seem to get the last part of my code to work correctly...

I have configured my app to display an error page (when necessary) and this will write errors to the event viewer along with my custom error messages - this works fine.

My problem is when I try to write these same errors to sql. Here is my code from web config:-

<code><healthMonitoring>
<eventMappings>
<add name="InputValidationEvent"
type="WebEvents.InputValidationEvent, WebEvents"/>
</eventMappings>
<rules>
<add name="InputValidationToSql"
eventName="InputValidationEvent"
provider="SqlWebEventProvider"
profile="Critical"/>
</rules>
</healthMonitoring></code>

Here is the code in my WebEvents assembly class:-

<code>using System;
using System.Collections.Generic;
using System.Text;
using System.Web.Management;

namespace WebEvents
{
public class InputValidationEvent : WebFailureAuditEvent
{
public InputValidationEvent(object sender, string message)
: base(message, sender, WebEventCodes.WebExtendedBase + 1)
{}

public override void FormatCustomEventDetails(WebEventFormatter formatter)
{
base.FormatCustomEventDetails(formatter);
//formatter.AppendLine("This is where you can write custom message for the event logger!");
formatter.AppendLine(string.Format("Actual error exception raised by the PNWeb app : {0}",this.Message));
}

}

}</code>

What happens when an error occurs in my app:-

1) Errors are written to the event viewer - which is ok.
2) In App-Data (within my app) an ASPNETDB.MDF file appears, along with aspnetdb_log.LDF.

It doesn't write the error to the aspnet_webevents_events table which exists in my DB?

So what I need to know is: Why does it write the error to the DB within the App_data folder & NOT to the aspnet_webevent_events table in my database?

Hope I've explained in enough detail - its driving me nuts!

Thanks
Janet

Hi,

I've just worked on something very similar, here is my code:-

protected void _gridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
//find the link button for each row being databound
LinkButton linkButton = new LinkButton();
linkButton = (LinkButton)e.Row.FindControl("_name");

//Needed as the first row is for the headings!
if (linkButton != null)
{
//set its CommandArgument so that this can be referenced in the RowCommand Event of the GridView!
linkButton.CommandArgument = e.Row.RowIndex.ToString();
linkButton.CommandName = "ImageClicked";
}
}

protected void _gridView_RowCommand(object sender, GridViewCommandEventArgs e)
{
if ((string)e.CommandName == "ImageClicked")
(
// Convert the row index stored in the CommandArgument property to an Integer.
int rowIndex = Convert.ToInt32(e.CommandArgument);

// Retrieve the row that contains the Linkbutton clicked from the Rows collection.
GridViewRow row = _gridView.Rows[rowIndex];

//use the findcontrol method
TextBox tb = new TextBox();
tb = (TextBox)e.Row.FindControl("_txtName");

)
}

Hope this helps
Janet

I find myself using "\n" when I'm writing to literals in javascript. I do this, because later when I view the source, to debug it, I get something that's intelligible rather than a single line. Ex:

<asp:literal runat="server" id="JSexample">

----- Later, in code-behind file ------

string jsString = "<script='text javascript'="">\n";
string jsString += "var something='This is something to say.';\n";
string jsString += "alert(something);\n";
string jsString += "\n";

JSexample.Text = jsString;

----- This way, I when debugging it shows up as: ----------

<script='text javascript'="">
var something='This is something to say.';
alert(something);

----- Instead of: ---------

<script='text javascript'="">var something='This is something to say.';alert(something);

This can make a big difference, when the javascript gets to be 50+ lines.

GridView printing problems

Hi All, I am facing GridView printing problems those are:
1. How can I get Formatted Contents of a grid using JAVASCRIPT.
function CallPrint(strid)
{
var prtContent = document.getElementById(strid);

var strOldOne=prtContent.innerHTML;
var WinPrint = window.open('','','letf=0,top=0,width=1,height=1,toolbar=0,scrollbars=0,status=0');
WinPrint.document.write(prtContent.innerHTML);
WinPrint.document.close();
WinPrint.focus();
WinPrint.print();
WinPrint.close();
prtContent.innerHTML=strOldOne;
}

Rightnow it displays all rows of gridview in one row
I tried outerHTML but this displays same GridView as it is in ASPX page. I want text format only with some formating so It can be readable and can be printed.
2. How can I print all rows of multiple page GridView, currently It is printing only the current page of GridView.
Many Thanks

Your making this tougher then it is. I would not try to print one section of a page via javascript. Just create a new page with only the content that you wish to print. For example if you want to print only a gridview copy and paste your grivdview into a new aspx page. On page load (re-load the grid) and then print.

Good luck.

Thanks ToddHileHoffer for suggestion.
Is using javascript for a new window that contains that gridView not a good idea
instead a new aspx page that contains printable contents(gridview).
I got almost I wanted to do except one thing that is, if GridView has multiple pages how can I print all pages using a single click. Right now I have to visit every page of that Grid View and then print.
If u have any better and simple idea that can print all pages of GridView, please post me. I will be highly thank full to u.

Turn paging off on your print page. That will lead to the problem of page breaks. You could add a counter in the itemDatabound event in the grid (along with a template column) you could add a page break via .css every 15 records or so. http://www.htmlgoodies.com/beyond/css/article.php/3470341

Although I've never tried that.

I am using BoundFields not the template column, So please tell me how can I insert a page break after each 15 records using BoundFields.
Thanks Again. Bye
