GridView Cells

[aljamala]

Hi,

I was wondering if there is a way to make a single cell readonly within
a GridView? I know you can do it for a column but what about a cell
within that column?

Thanks!

Thats for a DataGrid (Windows not Web controls)

Hello al******@gmail.com,

Sorry, missed topic a little bit (too tired after work)

Have u tried to handle CellBeginEdit and check the index of your cell in
GridViewCellCancelEventArgs to call Cancel property as described there

Thats alright Michael, I know the feeling.

However, the article you are referring to is again for windows forms, I
believe this is for the new DataGridView class.

This is what I'm trying to do, the property value DOES change, but I
feel like this isnt the correct way of doing it. There may be
something else needed missing?

Here is my RowCommand event code it will basically kick into edit mode
when a user double clicks on a row:

protected void GridView1_RowCommand(object sender,
GridViewCommandEventArgs e)
{
GridView _gridView = (GridView)sender;

// Get the selected index and the command name
int _selectedIndex = int.Parse(e.CommandArgument.ToString());
string _commandName = e.CommandName;
string _eventArgument = Request.Form["__EVENTARGUMENT"];

DataControlFieldCell cell =
((DataControlFieldCell)gameGrid.Rows[1].Controls[3]);
BoundField field1 = (BoundField)(cell.ContainingField);
//field1.ItemStyle.Width.Value = "100";
TextBox1.Text = TextBox1.Text + cell.Text;
lblStatus.Text = lblStatus.Text + field1.ReadOnly.ToString();
if (cell.Text == @" ")
{
field1.ReadOnly = false;
//cell.DataBind();

}
else
{
field1.ReadOnly = true;
//cell.DataBind();
}
lblStatus.Text = lblStatus.Text + field1.ReadOnly.ToString();
BindGrid();
switch (_commandName)
{
case ("SingleClick"):
_gridView.SelectedIndex = _selectedIndex;
this.Message.Text += "Single clicked GridView row at
index " + _selectedIndex.ToString() + " on cell index " +
_eventArgument + "<br />";
break;
case ("DoubleClick"):
_gridView.EditIndex = _selectedIndex;
_gridView.SelectedIndex = -1;
BindGrid();
this.Message.Text += "Double clicked GridView row at
index " + _selectedIndex.ToString() + " on cell index " +
_eventArgument + "<br />";
break;
}
}

I tried following the ReadOnly propoerty values across post backs
initial: False
my change: True
postback: False
my change: True
postback: False
mychage: True
.....

Problem fixed...in the RowDataBound event, I check if its in edit mode,
if so, then I check to see if the cell has a value and set the ReadOnly
property based on that.

protected void GridView1_RowDataBound(object sender,
GridViewRowEventArgs e)
{
DataControlFieldCell cell;
TemplateField field;

if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.RowState == DataControlRowState.Edit
|| e.Row.RowState == (DataControlRowState.Edit
| DataControlRowState.Alternate))
{
GridViewRow row = e.Row;
for (int index = 1; index < 10; index++)
{
TextBox4.Text = TextBox4.Text + "\r\n" +
String.Concat("SudokuCell", index).ToString();
TextBox theCell =
(TextBox)row.FindControl(String.Concat("SudokuCell ", index));
// lblStatus2.Text = lblStatus2.Text + (theCell.Text
== @"").ToString();
if (theCell.Text == @"")
{
theCell.ReadOnly = false;
//theCell.Enabled = false;
//TextBox1.Text = theCell.ToString();
}
else
{

theCell.ReadOnly = true;
//theCell.Enabled = false;
theCell.BorderStyle = BorderStyle.None;
theCell.BorderWidth =
System.Web.UI.WebControls.Unit.Pixel(0);

}
}
