Vb net datagrid cellvalidating
I have tried the below code on datagrid View Cellvalidation event but its not working.
I want that whenever user presses anyother key than a number key(ex:1,2,3,4....)than immediately i should get a messagebox that only numbers allowed.
A: If you want take input directly in datagridview, column of string type takes any input but Data Grid View default error dialog is shown when making invalid input i-e 123a for integer type column that asks to handle the Data Error event of datagridview . Data Grid View Cell Validating Event Args) Handles Data Grid View1.
So you can use Cell Validating event of Data Grid View to validate integer type column as well as other. Cell Validating Dim cell As Data Grid View Cell = Data Grid View1.
For example, this event triggers everytimes the users switches to another row.
On the other hand, the Cell Value Changed event seems to trigger only when the value of the cell changes, which means the validation code runs only when the value changes and not everytime a user changes cells.
Steps: Private Sub Data Grid View1_Cell Validating(By Val sender As System. Is In Edit Mode Then Dim c As Control = Data Grid View1. Please suggest on what event and how can i do such validation. I have a Datagrid View in my Winform and i can change all cells's value.
I would like to save the new cell's value with the Cell Validated Event with the Formatted Value.
Its works but when i change a cell empty, Formatted Value is empty too.
