Cellvalidating event in gridview great advice on dating
Since you have not added your new row yet it should validate OK.Or if not, then it is because the user has entered an invalid value in the current cell. Something there is causing the cell validating event to fire. [Edit] The validating event is firing because focus is being moved from the DGV to the button.Hi there, I have a question regarding datagridview, I add data to the datagridview in an interface and all the validation for the datagridview cell is in the datagridview cell validating event for the datagridview.I display the data of the is datagridview in another interface and make the cells read-only. But the thing is when I click on a row that data was added previously and press the Add new row the cell validating event is triggered.The Kettic Data Grid View allows users of the control easily validate data grid cells when data is committed to the data source.To validate data to grid cells and rows, we need to use the Validate Cell event, which will be raised by the Kettic Data Grid View when there are any changes to the current cell or when the grid cell loses input focus like.However, the user may prefer to validate all the data cells in a row at once.This scenario can be achieved by using the Row Validating event, which is fired when the user tries to change the current row (changing to another row or when the control loses focus).
Let's assume that the If the user enters empty string for a specific cell and tries to navigate to another row, the validation fails and the Error Text is displayed on the corresponding row.Or if not, then it is because the user has entered an invalid value in the current cell."The validating event is firing because focus is being moved from the DGV to the button.We are going through the following C# code to analyze the process of validating data in grid cell.The C# code snippet will enable the data cell validation in a textbox column for entering only none empty strings, which will disable the data validation and display the error indicator at the row header.
