I have a "simple" gridview that has some columns, and the ability for editing/deleting. I recently found that I can change the editing textbox to a dropdownlist and have follow that, using:
[Code]....
It's quite simple and instead of using an sqldatasource, I have successfully implemented using the sqlclient in the codebehind to bind data only when I want (since this GridView is for "reports" and is queried by many parameters from user inputs).From what I've found online, the only way people have populated the dropdownlist is by using an sqldatasource - is there any way to populate it using the codebehind sqlclient like I have for binding the gridview and other dropdowns on the page that are exactly the same actually. I'd obviously have to set the SelectedValue to be what the value is coming from the database, which I can't see being that difficult.
The tough part seems to be knowing when to access this "MoneyTypeEdit" dropdownlist. I thought it would be in the RowEditing event, so I tried something like:
[Code]....
And I know everything outside of the "inserted code" works, because it was fine before I added that, but the dropdown obviously didn't have any values. And I know the code inside the "inserted code" works because I use it somewhere else on my page to populate a similar dropdown. But I get the error that MoneyTypeEdit is null, and I'm guessing it's because it can't find the "MoneyTypeEdit" dropdownlist.
So question from a Newbie !So I have a web page with a Details View component for Inserting data into a table.One of the fields is a date/time which I want to be now().SO I guess there are 2 ways of doing it - either I populate the date/time field in the form with a variable that represent now() and make it Read Only so the user can't change it or I somehow make a hidden variable (ie not displayed in the form) that writes a date/time of now() into the database whenever an INSERT takes place.What is the best way and how do I do either of them ? How do I make one of the fields in the INSERT form of the Details View a preset variable ?

{
DropDownList DStatusEdit = (DropDownList)e.Row.FindControl("DStatusEdit");
string query = "select distinct status from directory";
SqlCommand cmd = new SqlCommand(query);
DStatusEdit.DataSource = GetData(cmd);

I am having problem with rowdatabound, want to add if conditions intact, i am using teh following two if conditions and they don't look right. i found them on google.
If e.Row.RowState = DataControlRowState.Normal Or e.Row.RowState = DataControlRowState.Alternate Then end if
If e.Row.RowState = DataControlRowState.Edit Or e.Row.RowState = 5 Then end if
With datagrids i use these and they work excellent:
If e.Item.ItemType = System.Web.UI.WebControls.ListItemType.Item OrElse e.Item.ItemType = System.Web.UI.WebControls.ListItemType.AlternatingItem Then
end if.....
