Vb net datagrid row validating

Please, could you elaborate a bit more and describe in detail what you want to achieve. I have a grid with values in it; quantity, price, discount (%), unit price.If the user wished to place a discount on each row, they enter it once, and then in a For Each loop, I place the value in the cell; however the calculation does not take place.

vb net datagrid row validating-47

I do have a visual basic 2005 - wrox book and 2 programing in visual basic books by Bradley and Millspaugh which I refer to alot. ----------------------------------------------------But just a little info on my situation.

I've copied some code from someone elses thread and made some changes. I had no idea at the time that the IT manager has absolutly no IT experience.

When I select data from my first combo box (not part of the datagrid) I get this error and shouldn't. I was told I'd be developing in VB6, and there was a person here how knew it, so for my first month here I was teaching myself vb6, until I found out they don't have it, it's ,net.

Ok, to make sure I understand, when I update a field through code, the calculations will not take place due to the Cell Validating event not firing.

If that is the case, is there a way to fire that event or do I have to manually calculate the values and manually update each field? Invalidate Row() method in the Cell End Edit event of the the grid to perform the calculations.

However, I am not sure that I fully understand your scenario. Regards, Jack the Telerik team I think I am looking for the same effect.

No values are changed in the data source before validation. If you do this, it will take care of the validation warnings for you. Index refers to the index of the current column which is being validated. You can sometimes get away with less code and overhead when you create your own code as opposed to what the GUI creates for you as well. If the value must be numeric, is it possible for you to set the Data Type of the column of your data source to a numeric data type? Until you're familiar with all of the intricacies of ADO. Net book and practice creating your connections, datasets, dataadapters, commands, etc. It makes a lot more sense when you can see and create what's going on behind the scenes.it appears as if the Cell Validating or Row Validating events are not firing.Here is my snipit of code: OK - sorry for the drawn out process.When I go through the loop, the last row is not displaying the calculated value, although the Cell End Edit event is fired performing the calculation and placing the values in the right cell. Thanks Hello Bob, Could you please send us your application and describe in detail the exact behavior that you want to achieve?
