I really like the part that you are explaining to your viewers what a specific code is for and what does it do. I've watched many tutorials related to c# and database but yours are more helpful. Others were just doing the code without explaining what's happening with the code. Thanks for that.

O problema nesse codigo que voce nao fez foi criar o codigo de nao ter o mesmo ID de produto quando voce tenta fazer o mesmo ID do produto ele retorna um error this line -> cmd.ExecuteNonQuery(); you can try make two produtct with same PRODUCT ID will get error why say exist on DB

[@ProgrammingGeek]

Product id is primary key. can't insert duplicate value in primary key/unique key column.

[@richardkingus]

Great Tutorial thank you. My datagrid only loads after insert and not on load. any ideas?

[@ProgrammingGeek]

call the method in page load event.

[@barneydinosaur3218]

Hi i have this error message, do you know what it means?
"The conversion of a varchar data type to a datetime data type resulted in an out-of-range value. The statement has been terminated"

[@ProgrammingGeek]

Check your datatype. Make sure that it is datetime. thanks

[@jasonkleinhanstechnologies685]

When i update the rows, the DataGridview displays duplication rows, how can I rectify the issue

[@ProgrammingGeek]

Check record whether the record exist or not in database before performing insert and update operation. Just watch this tutorial ruclips.net/video/svPQ1Ze6uTs/видео.html

[@raphsanchez95]

Hi, I'm doing an experiment on a lottary table which contains a "date" (column1) the "wheel" (column 2) and the other 5 columns with numbers, which would be the draws. I can't search for 5 numbers chosen by me in no particular order. For example:
The numbers to look for are:
22 34 67 87 90, in the search if there is such an extraction, it finds it only in order or in sequence as I write it, while my goal would be that the 5 numbers can be found even if in different positions, for example 22 not as first extract but second or third, fourth and finally fifth, so for all the others, since the combinations are different and the numbers can come out on different columns. How to do?

[@ProgrammingGeek]

In my point of view you can do it by using an array and a for loop then load data into datatable. 1 put the no into array. 2. search number in for loop using array list. during search load data into datable then load datatable into your expected control like gridview. Thanks

[@frajdimalaj7927]

how do i make the boxes clear after i insert or delete an item

[@ProgrammingGeek]

very easy. just put textbox1.clear(). or textbox1.text="";

How to re-assign ID after delete?

[@ProgrammingGeek]

Nice question. First of all don't use primary key in ID column. you can use Unique Key, If you want to put ID manually you can put after delete. If want to insert automatically use MAX +1 function. Thanks.

[@hatsu1101]

@@ProgrammingGeek actually It's a bad idea about putting primary key on a column. How about when two clients are trying to insert a new row at the same time. Thanks for clarification

[@ProgrammingGeek]

@@hatsu1101 In this case don't use textbox for ID. after inserting a record user can see the ID of this record. Add a where clause to get the record with name and one more field so that you can get the inserted record. by following it, no problem occurred if 100 clients try to insert same time. If you have better solution can inform me please.
