Hot cahat in telugu language - Vb net datagrid cellvalidating

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.

Please suggest on what event and how can i do such validation.

In the Cell End Edit event handler, set the Error Text property on the row to the empty string.

The Cell End Edit event occurs only when the cell exits edit mode, which it cannot do if it fails validation.

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.

1) Add a conditional statement in the event handler code to only execute when required.

2) Detach the event hander before the unwanted event triggers and re-attach after. Add("Price", "Price") '---create a new bindingsource control--- Dim bindingsource As New Binding Source '---add the items into the control--- bindingsource. Header Text = "Types" '---data bind it--- combo Box Col. Add("Type C") '---create a combobox column--- Dim combo Box Col As New Data Grid View Combo Box Column '---set the header--- combo Box Col. There are two ways to manage unwanted execution of event handlers. Data Grid View Cell Validating Event Args' does not contain a constructor that takes '1' arguments" what is the solution for this???????1) Add a conditional statement in the event handler code to only execute when required. Cell Validating -= new Data Grid View Cell Validating Event Args(dgv Sub Contractor_Cell Validating); it says that "Error 7 'System. hey what do ouy mena by the below private void data Grid View1_Cell Validating(object sender, Data Grid View Cell Validating Event Args e) if (adding Row) - is to call the button event for adding a new row is it every time the cell validating event triggers and a value is entered in the datagridview cell right??2) Detach the event hander before the unwanted event triggers and re-attach after. so when i click the add button the cell validating event triggers i have posted the cell validating event do you know how to solve this thanxxx code!!!
