I'd like to create code for my datagrid view to be able to delete a row by first clicking the record selector column then pressing delete. Seems like some standard stuff but really difficult to create in VB 2005.
Basically, I am making a booking system. On one of the forms, you can: Add, Edit and Delete a record by using the selected index. I can do the Add and Edit part fine but some problems are occuring when I try to delete it. What I'm trying to do when deleting is, copy all the records except the selected one and then copy it back into the original file again.
i have one textbox ,this textbox contains a number ,i want to delete a record by searching that number in two tables Table1 and Table2,the record may present in Table1 or Table2 ,so it should check both the Tables ,if it is found in table1 it should delete or else from table 2 it should delete.
I want to delete record from GridView.Before to this ask for confirmation like "Are you sure to delete?"I used command field in GridView, [code] I wrote a function in javascript. [code] How I will call this on delete click.
The following code loops through the rows of a datatable to process each record which has a Processed column value not equal to -1. When a record is processed, its Processed value is updated to -1. As a record is processed, the code within the Do Loop may add a new record to the datatable with a Processed column value equl to 0. All of that works as intended. My test set record gets processed and a new record is added.At the end of the For.Next code, there is a line , "clsWTAdapter.Fill(clsWTDataTable)", which I intended to refresh the rows so that it would include the newly added record which would then be processed during the next iteration of the For...Next sequence. This is not happening. What am I doing wrong, and how can I refresh the rows and process the newly added records?
I found this line in an MSDN page about DbDataAdapter Fill Method (DataTable) at [URL]"The overload of Fill that takes DataTable as a parameter only obtains the first result. Use an overload of Fill that takes DataSet as a parameter to obtain multiple results."Does this mean that I am on the wrong trackby using a datatable where I should be using a dataset? Does "multiple results" mean filling the dataset multiple times like I am trying to do with the datatable?
