Making the variable an instance member doesn't help a bit, as the instance of the Page class doesn't survive between postbacks.

Yes you are right. But he didn't explained that he is doing this in webforms. I thought it's in winforms.

A page object only lives while the response is created on the server. Once the response has been created and sent to the browser, the page object goes away.
If you declare a variable in the page object, it will only live as long as the page object lives. Once the response is sent to the browser and the page object goes away, the variable doesn't exist any more.
When you press the button, a new request is sent to the server, a new page object is created to handle the request, and the new page object contains a new instance of the variable that is assigned the initial value of zero.
Web pages are stateless. If you want to keep a value between requests, you have to either send the value back and forth between the server and the browser (using a cookie, viewstate or a hidden field), or assign it to a session variable.
Experience is the sum of all the mistakes you have done.

No it's not mandatory. SQLDataSource is for newbies which makes things very easy. You can put a template column on the main gridview and put another gridview inside the template column. On GridViews' RowDatabBound event, find the child GridView and bind it.

i am doing in the Folowing manner
protected void gvCars_rowDataBound(object sender, GridViewRowEventArgs e)<br />
{<br />
if (e.Row.RowType == DataControlRowType.DataRow)<br />
{<br />
GridView gv = (GridView)e.Row.FindControl("gvModels");<br />
AccessDataSource asd = new AccessDataSource(@"App_Data\SkinSample.mdb", "SELECT carmodel_name,carmodel_engine,carmodel_color FROM carmodel WHERE carmaker_id=" + ((DataRowView)e.Row.DataItem)["carmaker_id"].ToString());<br />
gv.DataSource = asd;<br />
gv.AutoGenerateColumns = false;<br />
BoundField bfModelName = new BoundField();<br />
bfModelName.DataField = "carmodel_name";<br />
BoundField bfEngine = new BoundField();<br />
bfEngine.DataField = "carmodel_engine";<br />
BoundField bfColor = new BoundField();<br />
bfColor.DataField = "carmodel_color";<br />
gv.Columns.Add(bfModelName);<br />
gv.Columns.Add(bfEngine);<br />
gv.Columns.Add(bfColor);<br />
gv.DataBind();<br />
}<br />
}
seems a little busy process because i have 15000 rows and doing paging @ 10
Sir , I have to show it in something like , there is a button in gridview in each row, on clicking the button at the particular row , it should view it's pertaining information into the same row.
i think , i should use the edit item template ?

No you can show the inner gridview on click of a button without any postback using javascript. Put your inner Gridview inside a HTML <div> element and make it's visibility to none. Assigns a JS function to the button which changes this div's display status to block. It will be very easy for the user to view the records.

This is not at all a secure method. You have to use parameterized queries which won't cause SQL injection problems.

In performance perceptive, selecting 15000 records and doing paging is not recommended. You need to look into custom paging.

I didn't understood what you mean ? Do you want to write an XML file in RSS structure ? RSS follows a standardized structure for XML files. To show this interactively, use XSLT.

Actually, RSS is a XML file with the RSS specific tag.. Please take a look at this link "What Is RSS?" to get more idea.

maybe. you doesn't add this dll in your setup... So, what you can do now is that you upload this dll on the server and register it or adding it into GAC. or..install Microsoft Office on the server

As Shujaat suggested, "Copy Local" might work but you need to re-package your setup file.. "Interop.Excel.dll" should be under bin\debug folder.
HatakeKaKaShi wrote: how to adding in to GAC
sorry. you don't need to add it in to GAC as this dll is COM..

Check The properties of dll you added and verify that Copy Local property is set to true.If not make it true and rebuild your Application.

Go to Solution Explorer There must be node with name References under this node you will get all the dlls you have added in your project now select the required dll right Click on it and go to properties now You would see the Copy Local property set it to true.

Hi,
I have recently encountered the same problem on my PC, my local IIS server would work with OWC11 but the remote server would not.
What ended up being the case is that the interop DLL was not installed on the remote server's GAC (global assembly cache).
One way to check and see if the Remote server has the correct interop in its GAC is to go onto your remote server, go into Start->Run (it has to be run because Explorer can't browse to it) and type in "C:\windows\assembly\gac". An Explorer window should appear, and if a folder named "Microsoft.Office.Interop.Excel" exists on the remote server, then my suggestion won't help. But, if this folder is missing, you can copy that directory from your local GAC to the Remote server's GAC.
A direct copy of the folder from PC to PC works; I had to do this when I was installing my application on my remote server.
I hope this helps,
Mitch

I had never experienced that error myself.
One suggestion that I will give to you to try and run "regsvr32 dllname.dll" on the DLL that you are using to interface with Excel (this is not the interop DLL that you just copied across).
When I did this on my server, I had to run "regsvr32 OWC11.DLL" to get it to work, however, the DLL that you have to register might be under a different name.
I hope this helps,
Mitch
