What are the issues? You can't expect to get help if you don't identify the problem.

my xml is like this
<laser lasername="newlaser" modelname="Nufern v1.0" serialno="1" manufacturername="Nufern v1.0.0.0" maximumpower="200" ip="192.168.1.173">
<tabular>
<property id="1" name="System Id" prgbar="false" selected="false" min="0" max="30" pwd="true" units="Sec" gauge="false">
<property id="10" name="Startup delay" prgbar="false" selected="false" min="0" max="30" units="Sec" gauge="false">
In the above xml there two child nodes for node "tabular" . In that one node has "pwd" attribute and another one don't have, it is optional one.
So I want to know that for the specific node the attribute is there or not at runtime----I tried like this
XmlDocument xmldoc2 = new XmlDocument();
xmldoc2.LoadXml(objXmlTasks.decrypt());
XmlNodeList xmlchildnodelst = xmldoc2.SelectNodes("/lasers/laser [@LaserName='" + laseridval + "']/properties/tabular/property[@name='" + childLaserSelectedName + "']");
Password= xmlchildnodelst[0].Attributes.GetNamedItem("pwd").Value;
But there is now pwd attribute for second one so exception
"object reference null"

Yes, you can't do it this way. If GetNamedItem fails to find the attribute, it returns null, so the call to Value fails with the null reference exception.
Instead, you need to do it like this:
XmlNode node = xmlchildnodelst[0].Attributes.GetNamedItem("pwd");
if (node != null)
{
Password = node.Value;
}
else
{
}
Also, please put the code blocks, including the xml, inside <pre> tags, which will keep the formatting and make it much easier to read.

I want to use RadioButton in DataGridView but I do not how to do that.
I just need a very simple Class for getting/setting its Checked state true/false.

Please help me to that. It is urgent

According to your question, I hope this article willl help: Build a Custom RadioButton Cell and Column for the DataGridView Control. You can also download the code samples for the project.
Windows Forms 2.0 offers several cell and column types for its DataGridView control. For example, the product ships with a text-box–based cell and column (DataGridViewTextBoxCell/DataGridViewTextBoxColumn) and a check-box–based duo (DataGridViewCheckBoxCell/DataGridViewCheckBoxColumn) among others. Even though the product comes with a rich set of cell and column types, some developers may want to create their own cell and column types to extend the functionality of the grid. Thankfully the DataGridView control architecture is extensible enough that such custom cells and columns can be built and used in the grid. This document explains how to create and use a cell and column that easily let the user pick an entry among multiple choices.

Could you give me another solution.
Thanks so much

That sample is about as simple as it gets for what you said you want to do. There is no "very simple" way to do this.

The simple way is that, but is not a proper way u can add the asp.net label control in the gridview column and in the event of databinding of gridview u can write html (

Please see the following code snippet
class BaseClass
{
public virtual void SampleFun()
{
Console.WriteLine("In base class SampleFun");
}
}
class ChildClass : BaseClass
{
public override void SampleFun()
{
Console.WriteLine("In child class samplefun");
}
}
class GrandChild : ChildClass
{
public GrandChild()
{
Console.WriteLine("Grandchild contructor");
base.SampleFun();
}
}
From grandchild class I am able to call the Child classes overrided method. But how to call BaseClass original method from GrandChild class ? When I try to call this.SampleFun(), VS editor shows two overloaded method. But I am able to call only ChildClass SampleFun() method. Is there any way to call BaseClass SampleFun() method.

base.base.SampleFun();
