    I think that's the whitespaces in the field names that are causing your troubles. I generally avoid using whitespaces in my databases. Where you list the field names - put every field name, containing a white space in single quote and of course - don't use names like 'Unit Price' for named parameters - use UnitPrice instead.

    Re: Failed to convert parameter value from a String to a Int32.

    Don't use single quotes on the parameters, only on the fields whose names consist more than of two words.
    Did you actually change the field names in your DB table?

    Re: Failed to convert parameter value from a String to a Int32.

    i don't think the error may be there, if so then
    is the datagridview is bound to data ?
    (1) u r trying to insert a string to a numeric field
    i suspect this line or lines
    (2) check this
    vb Code:
    1. row.Cells(0).Value.ToString
    when you are converting the value of a cell to tostring then there must be some value
    whether all the cells you are using are having values ?
    try using
    vb Code:
    1. row.Cells(13).Value

    check any one

    Re: Failed to convert parameter value from a String to a Int32.

    hawk eye cic !!
    jay
    here why the quotes around the field names & also around parameters
    vb Code:
    1. 'ItemName',CategoryID,Category,UnitID, Units, 'UnitPrice',Quantity, Amount,'UserName')" & _
    2. " VALUES(@RequsitionID,@Date,@DepartmentID,@Department,@ItemID, '@ItemName',@CategoryID,@Category ,@UnitID, @Units, '@UnitPrice',@Quantity,@Amount,'UserName')"

    Re: Failed to convert parameter value from a String to a Int32.

    You can leave the names in your database, still it's confusing that's why I try to avoid naming fields like 'Unit Price' - note that you should surround such names in single quotes if you use them. It'll be easier and less confusing if you name it like UnitPrice (w/o whitespace).
    As for the parameter names - I don't even know if multi-word parameters are supported, so you should use @UnitPrice even if the name of your database field is 'Unit Price'.
    And of course the names of the fields in your SQL statements must exactly match the names of the fields in the database table.

    Re: Failed to convert parameter value from a String to a Int32.

    still i could see quotes around the fields (please refer point number (2))
    nonqueryCommand.CommandText = _
    "INSERT INTO Requisitions (RequsitionID,Date,DepartmentID,Department,ItemID,'Item Name',CategoryID,Category,UnitID,Units,'Unit Price',Quantity,Amount,'User Name')" & _
    " VALUES(@RequsitionID,@Date,@DepartmentID,@Department,@ItemID,@Item Name,@CategoryID,@Category,@UnitID,@Units,@Unit Price,@Quantity,@Amount,@User Name)"
    (2) as far as i know in access when there is a empty space in the field name the field name was
    surrounded with [] brackets, i never user SQL server
    (3) break at this line nonqueryCommand.Parameters("@RequisitionID").Value = row.Cells(0).Value
    and check what are the values line by line
    (4) try to run your nonqueryCommand.CommandText SQL statement with in your SQL server query
    window and find out what exception it is throwing
    (5) for the time being remove the try catch block

    VALUES(@RequsitionID Vs .Parameters.AddWithValue.AddWithValue("@RequisitionID"
    see these 2 red words in u r statement both should be same
    accordingly change them as @RequsitionID
    vb Code:
    1. .Parameters.AddWithValue.AddWithValue("@RequsitionID", .Value = row.Cells(0).Value)
