NULL problem

[Xmen Real]

hi there, i have a problem that how can check the value of datagridview is null ?? if i write

if (DataGridView1[5, a].Value.ToString() == null)

or

if (DataGridView1[5, a].Value.ToString().Contains (null))

or

if (DataGridView1[5, a].Value.Equals(null))

all gives the same error Object reference not set to an instance of an object. for temporary i did

string aaa = DataGridView1[5, a].Value + "D";
if (aaa.Trim )== "D")

its working but i dont like this way some know any other good and short way ??

Hello, Have you tried: if (DataGridView1[5, a].Value != null) { //Go on }

All the best, Martin

Did you try this? DataGridView1[5, a].Value == DBNull.Value

Hi, According to the exception it is quite clear that CLR bumped into a null value while evaluating "DataGridView1[5, a].Value" what means "DataGridView1[5, a].Value.toString()" if "DataGridView1[5, a].Value" is null ?? You might not assume DataGridView1!=null nor a!=null nor DataGridView1[5, a].Value!=null though the following test should solve your problem : if (DataGridView1[5, a]==null or DataGridView1[5, a].Value==null) { /// } Hope it helps

I guess this will not help, if this is true: for temporary i did string aaa = DataGridView1[5, a].Value + "D"; if (aaa.Trim )== "D") its working but i dont like this way

All the best, Martin

I think your grid must be having only 5 records from 0 to 4. So its not geting the 6th record.
