i have a dropdownlist that bind with sqldatasource1. everytime i load this page, dropdownlist will display directly the content of data.
However, what i want is display empty message like --Please select your currency-- by default.
I make SqlDataSource1.DataBind(); with some parameters on button click,
then I'm working with a Grid onDataBound();
but if my SqlDataSource1 returns empty data I've got an error even if I'm trying to check if (GridView2.HeaderRow.Cells.Count != 0) so I guess I need to check it on SqlDataSource1 someway.
How to get sqldatasource1.selectCommand value
[Code]....
i want to set that if nothing return i will display a msg to users.
I am getting the following error:
Must declare the scalar variable "@Approved"
I want to add a parameter to my SqlDataSource1 when certain controls are checked.
[Code]....
I have a query that looks like this attached to a sqldatasource :
SELECT [fldBaseline] FROM [BI_PATHS_Target_Baseline] WHERE fldBranch = @fldBranch and
fldyear=@fldyear and fldcategory = @cat
and i want to make a LABEL to read that fldbaseline value and i tried this :
[Code]....
btw the @fldbranch is pulling from a dropdownlist and so it the @year but the @cat is just defined always as 'LEAN' But im not sure what to put inside the select() part. i know you have to put atasourceselectarguments.empty if no parameters, but what would I do here since their are 3?
