I have a database and a dataset as the image shows in the link, how would i add the values of the colums "amount1" and "amount2" for every row and entry as the user make entries to be automatically displayed in the "total" column. Meaning that every time values are entered in those amount columns, they will be added and the total displayed in the "Total" column.
ei guys how to compute values in a datagrid column.. we have just tried some codes but it appers false anyway.. just need it badly.. i just have 30 min. :CCC
I am using vb.net and WPF. In a wpf window I am showing a datagrid in the load event while in the load event itself, I need to count grand total amount from a single datagrid column and add it to a textbox in same page .
My page looks like this: My DataGrid: Item Quantity Total Shirt 2 200 Pant 1 500 Tie - - Belt 2 100 My Textbox ---> Grand Total amount : - 800
How do I do that if I am counting from a ((Total Column )) DTG And adding it and showing it in my (( GRAND TOTAL AMOUNT)) TEXTBOX
I was wondering the best method or code to Sum\total a bunch of cell values of an unbound column in a datagrid to a textbox string. this request is 100% genuine...im not some student trying to get you guys to finish my project, this is purely for educational and personal information for myself. im new to vb.net.
am trying to calculate the values in rows in column 6 based on values of column 5. Bellow is the the code I am using I get a run time error about the string not formatted properly
It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
Private Sub DataGridView1_ColumnHeaderMouseClick(sender As Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick Try
