Hi,
I have a datagridview and on cellmouseclick the following code is called:
On the form, I have a 'Search By' with a dropdownlist i.e., ALL, firstname, lastname.
On Formload by default it has 'ALL' selected with all the records displayed on the datagridview.
Now, if I 'Search By' - firstname and enter details on the textbox the datagridview gets populated accordingly.
The issue is if I click a cell on the datagridview to display the content on another panel with textboxes and picturebox I get the following error message:
The following code is highlighted in GREEN
N/B: When I click cell when the datagridview is populated on formload i.e., 'ALL' is selected by default - this problem doesn't exist
Thanks
I have a datagridview and on cellmouseclick the following code is called:
Code:
Private Sub DgTenantDetails_CellMouseClick(sender As System.Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DgTenantDetails.CellMouseClick
