If I recall correctly, since .net 2.0, the cells have had a background color property.
However, back when I was thinking of doing that, I decided to use a TreeView instead -- I avoid data grids whenever possible.

I have <Contact> nodes within <Contacts> elemnt and I am binding it to a datagrid using ReadXML. If I place a button for MOVE UP and another button for MOVE DOWN, the how can I re-position the nodes in the XML file?

I would use XPath or XmlDocument and then rebind the grid.

Either manually, or by sorting the entries. Assuming that you'd want to sort it, there's two ways of doing so. The first option would be to use XSLT[^], the second option would be using the XmlDocument class to sort[^] the nodes.

but this will sort based on something.. what I actually want is just a simple MOVE UP and MOVE DOWN button which will move the row in the DataGrid as well as the actual XML file

Simple as it may sound, it still needs to be programmed. The buttons should do something to the grid, and the XML. Back to Danish;

His answer is completely valid; you can use the XmlDocument-class to manipulate the XML. "Rebind the grid" means that the next step would be to load that XML back into the datagrid.

Another option would be to add a field that says "order", and to sort on that - that way the buttons only need to change a value, as opposed to changing the complete order and structure of the Xml file.

Datagridview Error

I have a datagridview bound to a datatable. When I remove a row from the datatable the grid reflects the change, but when I attempted to add a row back in I get an error System Index out of Range? I have tried datagridview1.Refresh() with no luck. What am I missing?

Thanks

Instead of refresh you can try to rebind the grid after deleting.
(or) if this is a wrong solution a code sample would help a lot to give clear solution.

Is there an article or code sample showing rebinding? Here is my code:

//Are there rows that need to be deleted?
for (int x = 0; x < dsInvoice.Tables["Invoice"].Rows.Count; x++)
{
if (dsInvoice.Tables["Invoice"].Rows[x]["QTYORD"].ToString() == "0")
{
dsInvoice.Tables["Invoice"].Rows[x].Delete();
dataGridView1.Refresh();
}
}

Thanks for all your help

Here is the mistake, you are getting the value from the database but after that deleting temporary. This will not reflect in database.

I created a DataSource with a DataTable in it and added it through the wizzard when I added the Grid to my form. When a user enters 0 in the first cell I want to remove that row from the grid.

I hope this helps

Thanks!

How are you adding the row after deletion? Since you are getting IndexOutOfRange exception, you should check all the indexes you are using while adding the row.

I am clicking on the first cell in the next available row when I receive the error. When I selected the datatable to use for the grid it created a binding source. When I try to execute the RemoveAt with the binding source it errors out.

Is there an easier way to do this?

I have never used a wizard for doing something like this. I had set the datasource through code and deleted the row using same code as yours. I added and new row as well and didn't received any error.

how to clear cookie programitically

protected void btnAdd_Click(object sender, EventArgs e)

DropDownList1.DataBind();

}
protected void Button1_Click(object sender, EventArgs e)

Response.Cookies.Clear();
Request.Cookies.Clear();
DropDownList1.DataBind();

i have executed 1st method many times as to add more and more Cookies

and then i have executed 2nd method ones.This should Clear all items in deopdownlist1. but its not cleared

can anyone tell me why?

for (int i = 0; i < Response.Cookies.Count; i++)
Response.Cookies[i].Expires = DateTime.Now.AddDays(-1);
for (int i = 0; i < Request.Cookies.Count; i++)
Request.Cookies[i].Expires = DateTime.Now.AddDays(-1);

this is also not working

string[] c = Request.Cookies.AllKeys;
foreach (string co in c)
{
Response.Cookies[co].Expires = DateTime.Now.AddDays(-1);
}
this is working..

any idea why this approach is right and above 2 are wrong?

DataGridViewDataErrorContexts problem

Can anybody explain to me how I handle the DataError Event? I have the
following code but the error does not get picked up by any of them. Looking
at e.Context shows " Parsing | Commit | CurrentCellChange ", how do I get
the individual values?

if (e.Context == DataGridViewDataErrorContexts.Commit)
{
MessageBox.Show("Commit error");
}

if (e.Context == DataGridViewDataErrorContexts.CurrentCellChange)
{
MessageBox.Show("Cell change");
}

if (e.Context == DataGridViewDataErrorContexts.Parsing)
{
MessageBox.Show("parsing error");
}

if (e.Context == DataGridViewDataErrorContexts.LeaveControl)
{
MessageBox.Show("leave control error");
}

Hi,

DataGridViewDataErrorContexts is an enum and has the FlagsAttribute, which means all members are really bit-oriented flags, so try this:

if ((e.Context & DataGridViewDataErrorContexts.Parsing)!=0) {
    MessageBox.Show("parsing error");
}

PS: please use PRE tags to show code, as I did (see the difference?)

Smile | :)

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.
