C form validating event not firing


14-May-2020 17:34

I'm Developing a Windows Forms application with a datagridview bound to a datasource.In the process of validating some cell values the Row Validating Event does not fire when navagation moves off the row. However, if i change a cell value, Tab back to the left to another cell on the same row, then use the mouse to click on a Previous row above the changed row..... Example:: A B C D 1 x x x x 2 x x x x 3 x x x x If I change the value in C2, then backtab (or mouse click) back to B2, Then mouse click on any cell in row 1, the Row Validation Event does not fire and thus the changed value in C2 does not get evaluated. I am using Cell Validating but if one cell is dependant on another I cannot navagate away from the invalid cell to change the parent cell controlling the validation logic.On the parent User Control I call the Validate Children() method.But the event handler for the child control's Validating event does not run.I am manually handling the Datasource Update which is dependant on the validations. Example: I have both a "Company" column and a "Division" Column.

I had simply copied and pasted the code provided by google, which has a form tag in it. Anyone having problems where your buttons don't work in IE but do in other browswers, make sure you don't have any form tags other than the single form tag that is set to run at the server. After a day of pain wondering what I was doing wrong with every control I tried, I discovered after reading these posts that things were working just fine in Fire Fox (but not IE) and there was a element inside the form. Our SOLUTION was to remove the other form and used javascript to exec it instead (get the element values from the input fields and send to a function to process). This was causing many problems such as the button_click event not being fired, as well as, when the event was firing, values such as were being returned empty. NET 1.1 to 3.5 sp1 and no events work ONLY on my local environment on other dev environments it works fine. Loud in this in both hold.video converter Thanks, I fixed this for . The Causes Validation property is set to true on both the parent User Control and the child control.Is there any reason why the Validating event handler would not run? thanks in advance HI, I am having the problem very frequently on the production server. Actually it worked fine in 3 days back,but suddenly stoppped.
