Gridview code for insert,delete,update

Question

0.00/5 (No votes)

See more:

Here I have taken Gridview in the design by using the Gridview task add new column I have generated delete,update,insert buttons by using the DataSource.

I have written command for delete,update,insert as -

C#

DeleteCommand="DELETE FROM Empdetails WHERE (Empname =raghu)";

And

C#

UpdateCommand="UPDATE Empdetails SET Empid = 1865201, Empname = 'Reddy' WHERE (Empid = 1865200)"

By doing this it is deleting,updating only particular Empid, but I need code for deleting all the records,and updating all the records where we click the update any button in the row of Gridview.

The code which I need is only for in Gridview delete,update ,insert buttons.
For example here - Gridview in this

empname|empid|city|
raghu |18652|hyd| Delete(button)|Update(button)|insert(button)
ram |1547 |hyd|Delete(button)|Update(button)|insert(button)

Like I have records and delete,update,insert buttons.

Here I need code for only clicking the update in every row it should update, similarly delete ,insert buttons also.

Solution 3

Firstly deleting on the basis of name is wrong. You must have a field holding unique value. As all the records with the name "raghu" will be deleted, better use Empid

Secondly your query is wrong, it should be like this

DeleteCommand="DELETE FROM Empdetails WHERE Empid=1011";

or for what you are writing

DeleteCommand="DELETE FROM Empdetails WHERE Empname ='raghu'";

But Raghu in database a query will be fired against name, where the name matches that all records will be deleted, may be one row or more. I hope u undrestand what i m trying to say.
