Refreshing gridview with new data

Question

I have a combobox and  a gridview. whenever an item from the combobox is selected , the gridview should be populated with related records.

My question is how can we refresh the datagridview with new  data and remove the old one.

 

Right now  when i click on combobox item A , the gridview displays  item A records.

Then when i select combobox item B, the gridview displays Item A and B records.

 I only want item B records to be displayed

 

Answer 1

You need to polish yourself to get a software developer/engineer job if not got placed in campus. There are many vacancies but companies wants ready-made hands. So, be tuned on latest trends with good understanding on basics.

A report says, there would around 1.5 Lac vacancies in this year. Last year they calculated it around 1.8 Lac. Don't worry, this figure is based on some parameter but actual employment was more than this as there are many startups and small firms has some take-on. 

Best of Luck!
