Have you tried googling for 'DataGridViewTextBoxColumn AND DataBinding'?

If you don't want to use DataSet/DataTable etc. Look up 'bind object to datagridview'.
Play around with the code from the results that you get and come back with any specific problem that you have with code you have written in trying to resolve your problem.

You can do something like this

DataSet ds = new DataSet();
ds.ReadXml("XML File Path");
DataColumn colPK= ds.Tables["tablename"].Columns["PKColumn"];
datagrid1.DataSource = ds;
datagrid1.DataBind();

You can design the datagrid to bind the values as required. if you want to add the fields in listbox

int i=ds.Tables["tablename"].Rows.count
int j;

for(j=0;j<i;j++)>
{
listbox.item.add(ds.Tables["tablename"].Rows[j]["colname"]);
}

syntax may not be correct. check into it... Smile | :)

log incoming sms to a form, then can be deleted one by one

I'd like to log some certain incoming sms to a form and I've came out with this code.

if (parent.checkBoxReplySMS.Checked)<br />
                {<br />
                    SmsMessage msg = new SmsMessage(request.From.Address, parent.textBoxMessage.Text);<br />
<br />
                    msg.Send();<br />
<br />
                    parent.documentSms.AppendFormat(@"Body: {0}<br />", request.Body);<br />
                    parent.documentSms.AppendFormat(@"Name: {0}<br />", request.From.Name);<br />
                    parent.documentSms.AppendFormat(@"Address: {0}<br />", request.From.Address);<br />
                    parent.documentSms.AppendFormat(@"Last Modified: {0}<br />", request.LastModified);<br />
                    parent.documentSms.AppendFormat(@"Received: {0}<br />", request.Received);<br />
                    parent.documentSms.Append(@"<br />");<br />
<br />
                }

But the problem is, if I want to clear the log, the code will erase all incoming sms which have been logged. What I want to do is, I can click the message and just delete that sms, not all.
Do you have any idea?

Depends on how you store them. If you use a DB, that would be easiest to manage. Otherwise, do you have a message id you can use, then you could use XML to store it all.

I am trying to implement paging in a datalist control but it seems so complicated anyways, i am using a stored procedure instead of a data list and the value is inputted from a querystring, but i just can't seem to find any example that implemented it my way. Anyone with any great walk through?

ASP.NET multiuser dataset shared problem

Hi,

I am creating a webpage that retrieves data from remote database and stores it in a dataset based on a sql query. Later this dataset is bound to a datagrid in the same page. This is working fine, for a single user. Problem is when multiple user are using the webpage, the dataset gets updated with all rows that are retrieved by other users. Hence the datagrid show what I searched for and also what other users are searching for. Can anyone help me solve this issue?

You haven't provided any code. So I assume you have declared the DataSet as static. If yes, you need to change this.

And what is the Main class? How do you persist the instance of the Main class from one request to the next? Does each user have their own instance of the class, or do you have a static reference to a single instance of that class?

Despite everything, the person most likely to be fooling you next is yourself.

The data set is local for the request, so there is nothing in your code that suggests that a search by one user would affect a search by another user. Therefore the problem has to be in the part of the code that you haven't shown.
