1. For the first task, you can capture any suitable event of the
DataGridView in which you can get the content of the selected cell like
CellClick etc
2. To pass back the data to MainForm
There are many ways to do it. I choose the simplest one.
Create public properties in Second form and while closing this form, set the values of those properties with the selected values.
3. To get the data passed from form2
When the form2 closes, read the public properties created in step2

Just have the MultiplesFound form expose a public property indicating the row that was selected by the user.

<br />
if (ds.Tables[0].Rows.Count > 0)<br />
{<br />
//Used if there is only one Row returned.<br />
int SelectedRow = 0;<br />
if (ds.Tables[0].Rows.Count > 1)<br />
{<br />
cardNumber = txtCardNumber.Text;<br />
MultiplesFound myMF = new MultiplesFound(cardNumber);<br />
myMF.myCardNumber = cardNumber;<br />
myMF.ShowDialog();<br />
//Retrieve the row selection<br />
SelectedRow = myMF.SelectedRow;<br />
}<br />
//Display the selected Row (or first row when only one has been returned<br />
txtProductCode.DataBindings.Add("text", ds.Tables[SelectedRow], "prod_code");<br />
txtDescription.DataBindings.Add("text", ds.Tables[SelectedRow], "prod_desc");<br />
txtModelNumber.DataBindings.Add("text", ds.Tables[SelectedRow], "model_no");<br />
<br />
}<br />

What part of that don't you understand? Also, if you don't post your code, how are we supposed to tell you how to correct it?

//Remove the charset from the Content-Type header
Response.Charset = String.Empty;
Response.AddHeader("content-disposition", "attachment; filename=" + calFrom.SelectedDate.ToString("YYYYMMdd") + ".xls");
value is not posted in the calfrom date too

System.IO.StringWriter myTextWriter =new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter myHtmlTextWriter = new System.Web.UI.HtmlTextWriter(myTextWriter);
grdReport.RenderControl(myHtmlTextWriter);
error is coming here

//grdReport.RenderControl(myHtmlTextWriter);
//Write the HTML to the browser
Response.Write(myTextWriter.ToString());
//End the response
Response.End();

The problem is with the ASPX, not the CS file. Do what the compiler suggests, and if you stil face problems, post the relevant ASPX code. In the right forum.

First This is an asp.net question so you should have posted it in the correct forum.
And regarding the error it states that the gridview control has to be inside the form control which should have runat=server attributes.

Have a look at String.Replace method but remember that it will delete all occurrences from the string

I would suggest to use the System.Collections.Specialized.StringCollection class instead.

You can also use StringBuilder. It depends how many times you will use it

Hello,

I wouldn't prevere the StringBuilder as an alternative to a string[].
I would miss methods like Contains.

You can't easily. You'd have to copy the array to a second array leaving out the string you don't want.
Just use List<string> instead.

Problem with Creating a New Project of Compact FrameWrok

Hi,
I am trying to learn C# for a few months. I have managed writing my own classes and developped a few little .NET applications. My Pc has .NET FrameWork of ver: 2.0 .
Recently I have a need to create a new project (In Visual Studio - 2005) for some kind of small devices that runs Windows CE and have Compact FrameWork. In Visual Studio 2005 I do this steps "File\New\Project" and choose "Visual C# \ Smart Device" and <pocket pc="" 2006=""> Or <widnows ce="" 5.0=""> as project type, and choose <device application=""> .. Just to new a project for mobile devices.
Unfortunately creating fails with this message ("This Project requires .NET Compact FrameWork v2.0, whics is not installed on this machine"). And also I tried Device Application(1.0) but the result is an error. Althoug I use C#, just to test I tried this in Vb.net but I failed creating a new Device App. project.
What does it mean ? Should I install Compact FW 2.0 on my PC, which seems strange to me ? Confused | :confused:

And I also should mention that while I was intalling Visual Studio-2005 with a Custom Instalation in which I only not choosen the J# components. I am sure that I selected all other compnents (Vb.net, C#, Web programming Tools, Device porgramming Capabilities.. things like that )
Frown | :(

Thanks for all in advance.

You need .NET Runtime CLR. For Solaris, there should be a distribution from Mono.
