what do you mean exactly??
did you mean you want to update/select/insert/delete data on database from datagrid??
if you mean this,don't worry this is a simple job,
just use SqlDataAdapter and set these commands for it:
SelectCommand
UpdateCommand
DeleteCommand
InsertCommand

see this sample for more details:

in general you can export your xml data to sqlserver using SSIS(Integration Service)
but if you mean that your xml data binded to a grid and you want to insert these data into sqlserver from your grid, i think you can generate a datatable from your grid data, and then insert your datatable into sqlserver table completely.

There is no Select method in DataSet class. Also, DataSet is not designed for XML manipulations.

Member 3981366 wrote:
dataview

What this has to do with XML?

Member 3981366 wrote:
xmlDocument.SelectNodes

XMLDocument.SelectNodes or XMLDocument.SelectSingleNode with XPath expression will be fast.

Member 3981366 wrote:
xmlNavigator.select

AFAIK, this class is no longer used.

datagrid problem!

Hi to all,

I have a datagrid in which there is a checkbox and a textbox.
The user can change the value in textbox.
below there is update button.When the user presses the update button
the textbox value should be updated.

For this I have done this:

protected void BtnUpdate_Click(object sender, EventArgs e)
{
    dt = (DataTable)Session["data"];
    DataGrid2.DataSource = dt;
    DataGrid2.DataBind();

    //if I will not bind then it will not go in foreach loop.
    //as it will not find any items in the datagrid.

    CheckBox chkSelected = new CheckBox();

    foreach (DataGridItem dgItem in DataGrid2.Items)
    {
        chkSelected = (CheckBox)dgItem.FindControl("chkSelection");

        if (chkSelected.Checked != true)
        {
            TextBox TxtQTY = (TextBox)dgItem.Cells[2].FindControl("TxtQTY");
            string Txt2 = TxtQTY.Text;

        }
        else
        {
            int a = 1;
        }

    }

}

The problem is that this functionality is not taking the user input.
In the starting I have done databing because of which it is taking the previous value.But if I will not bind the data It is not going in the foreach loop to check wether any checkbox is selected or not as in debugging it is showing that the item collection in the datagrid is empty.

Please give some suggestions...
Thanks in advance.

cheers,
sneha

Problem is in above code.
You are rebinding DataGrid before fetching new values from textbox. This will over write all the previously entered text.

Try moving this code after you have read value from textbox

Why is the datagrid losing all the items. You may be doing something before reaching to this event.

This will clear the values changed in the textbox. Why do you need to rebind the grid?

Which event are you using for binding the grid? Is viewstate enabled for this control?

do you really want this in your web application. Bcos we often need this for Windows Application.
For windows use:
System.Net.NetworkInformation.NetworkChange.NetworkAvailabilityChanged += new System.Net.NetworkInformation.NetworkAvailabilityChangedEventHandler(NetWorkChangedCallback);

This has to be the dumbest thing I have ever heard.

If you're on a LAN and you want to know if an internet connection exists or not, just ping google or microsoft and if you get a reply or not, you'll know if you're online.

Yes Christian is Right.
For web application, just make an object of XMLHttpRequest and do an AJAX call to any page using SetInterval, so that this ajax call will occur after a certain time. And show the status message based on the reply from the server.

Thats all is possible in WEB... Cool | :cool:

I tried the DSN Management in Web Space Configuration but it seems only mysql is available and my database is oledb.

Thanks in advance. Wink | ;)

no, not this one.

what i mean is i have a free ASP.NET host. I can only access the control panel and ftp. But i don't know where they put the wwwroot directory.
I want to know where they put the directory path of wwwroot so that i can put the connection string on the webconfig file.

I mean this too,
try this:
create a simple aspx page with this code on page_load:

Response.Write(Server.MapPath(""));

then upload the aspx page on your free host, and browse it and see your result.
