Hi,

I am binding a dropdown box to a datareader, I would like to limit the length of the strings because if the string is grater than 25 CHR then it starts to push my formatting on my page around


        Manufacturers.DataSource = ManuReader
        Manufacturers.DataTextField = "SupplierName"
        Manufacturers.DataTextFormatString = HERE IS THE PROBLEM
        Manufacturers.DataBind()

I know I can loop through the datareader and use left(STRING,25)  but I would like to know if I can use DataTextFormatString

Thanks

The easiest way would be to change your SQL to only return the first 25 characters of the field with SUBSTRING function.

DataTextFormatString is for numeric formatting.

So what should the format do when its longer then 25 characters, that what i dont' understand???

This will code will make it so the dropdown is 25 characters long.
Manufacturer.Width = 25;

kaffay, What would my SQL look like? currently it is

SELEC DISTINCT SupplierName From Products ORDER By SupplierName ASC


BirdBuster, When over 25 CHr long I would truncate to read  "phillips semi cond..." or similar. I tried setting the width iof the combo box, but it resizes it when you put a 50 CHR string in it and as it is in my Nav bar on the l;eft of my page it pushes all my tables about.

Depending on the version of MySQL, you should be able to do something like this:

SELECT SUBSTRING(Field1, 1, 25) AS Field1

   or

SELECT LEFT(Field1, 25) AS Field1
