Hi all

i am developing a project and on one of the form i am having a very weird Problem.Here is the Detail

1) i have added new data source from the data menu and then designed this form by selecting detailView from data Source Window and Draged and Droped on to the form.

2) Atfer Few Days i added 4 more fields to the database and configed the data set accordingly and draged and droped new field to the form as well.

3)But one of the new fields is not being saved to the database (saving null).all the other 3 new fields are being saved Properly

4)After spending alot of time on it.I set a watch on that textbox and set breakpoints on save button cl;icked
and found that when bindingsource.EndEdit() method is called it clears the textbox value.Before this EndEdit Method is called that textBox contains the value but after the execution of the EndEdit method the textbox is cleared

Any Ideas y this is happeding ????
thanks

When this happend to me, i had the wrong binding set on the textbox.

Verify that the DataBinding is on the TextProperty...

this .textBox1.DataBindings.Add("Text" , bindSrc, "Name" );

yes Telephone_previous is a string type in my dataset and nvarchar(50) in my database

"3)But one of the new fields is not being saved to the database (saving null).all the other 3 new fields are being saved Properly"


what are you doing to save null. ?

For this you have to set DataSourcenNullValue

Binding b = new Binding("Text", applicantsBindingSource, "TelePhone_Previous", true);

b.DataSourceNullValue =

b.DataSourceNullValue =

null;

this .TelePhonetextBox.DataBindings.Add(b );
