I have a FormView control that will either enter or update one (and only) record in a datasource. I need to set the FormView mode based on whether there is a record in the datasource. I know how to switch modes by reading the datasource myself, but is there a way to get the FormView to do it automatically? Or is there a way to get FormView to allow an Empty Template to update the database? It doesn't seem the Empty template will bind to a datasoource the way the Edit template does.

Hi
I thought I had sorted this but I was wrong.
Basically Ive need to get a column value for the current row I am trying to update. The update is happening on a dropdownselectedchange click event. I thought that if I added in:
string strID = GridView1.DataKeys[x].Values[1].ToString();
it would work but it doesnt perform the update. I need to get another column id for the current row I am updating
any help on this would be great
thanks! 
public void dd_OnSelectedIndexChanged(object sender, EventArgs e)
{
for (int x = 0; x < GridView1.Rows.Count; x++)
{
GridViewRow row = GridView1.Rows[x];
string strID = GridView1.DataKeys[x].Values[1].ToString();
SqlCommand cmd_update_activity_order = new SqlCommand("update_activity_order", con);
cmd_update_activity_order.CommandType = CommandType.StoredProcedure;

if you are trying to update only one row, Why there is a for loop inside SelectedIndexChanged event.
EVEN THE WORD IMPOSSIBLE SAYS I M POSSIBLE.
|
|
|
|
|
because another person on this forum told me to do it.
Do you know how I can get the current selected dropdownlist value and the another column value from the same row?
|
|

.netman wrote: current selected dropdownlist value
Because of you are going to do this in the SelectedIndexChange event,
You can you the 'sender', convert sender to dropdownlist and use selected value.
.netman wrote: another column value from the same row
How you are going to identify the current row(index of the row)?
If you know then, What is the problem of getting the value?

Can you explain what you mean by sender

I'm not sure how to get the current row values e.g. another column

I was talking about the sender object in the OnSelectedIndexChanged Event handler
In the OnSelectedIndexChanged Event, you can use something like below...
DropDownList dropdown=(DropDownList)sender;
dropdown.SelectedValue <-- gives the selected value

.netman wrote: I'm not sure how to get the current row values e.g. another column
One way of doing this is to store the row number in the value field of the dropdown,
Eg:
in first row dropdown
Text value
1 1_1
2 2_1
3 3_1
4 4_1
1_1 will change to 1_2,2_1 to 2_2 and so on in the second dropdown
If you select 4 from 3rd row you will get 4_3 as value
So that you can retrieve the row index from this value field as follows
string val=drop.SelectedValue;
string rowNum=val.Substring(val.IndexOf("_")+1);
Hope this will help you

Use DataKeyMember and DataKeyValue in your GridView.
In the OnSelectedIndexChanged(object sender, EventArgs e)
DropDownList ddl = (DropDownList)sender;
GridViewRow row = (GridViewRow)ddl.NamingContainer;
In that case you have the data of the GridViewRow that caused the Event.
GridView.SelectedIndex = row.RowIndex;
You know know the rownumber and with GridView.SelectedValue you know the DataKeyValue.
AT the end of the Eventhandler you state:
GridView.SelectedIndex = -1;
Good Luck

Assuming you are running this from a web page, you do not by default have permission to write to the file system, so I suspect that is your problem.

You need to create a datatable and add your data to it, you cannot cast an array to a datatable. If you want to allow nulls in the columns you will have to decalre them as nullable too.
This should get you started
dt = new DataTable();
dt.Columns.Add(new DataColumn("x", typeof(String)));
DataRow dumRow = dt.NewRow();
dumRow[0] = "All";
dt.Rows.Add(dumRow);

well I don't know about casting, as per previous answer, but you can certainly bind an array to a datatable... clickety[^]
