View 1 RepliesHow to programmatically change foreground color and make bold text in individual cell location on DataGridView control (Visual Basic)?
I use "dgMatrix.Rows(r).Cells(c).Value = x" to assign individual numeric values to individual cells in a DataGridView control. My question; is there a similar way to change foreground color and make bold the text in this cell, by specifying the individual row/column cell location?
For example; for cell (row 3, col 5) in the DataGridView make text in cell say red and bold or blue and bold so as to highlight and distinguish individual cell contents. As needed, I will also need to reset these properties (foreground back to automatic/black and font from bold back to regular); the reset could be done globally to the whole DataGridView as opposed to indiviaually by cell.
I have a DGV I am working on, and I have many columns.
For example I have Columns colcase(Combobox), colreportTime(Time)
the combox shows 4 cases {A,B,C,D}
what I need to do is if the user select "C"
the the colreporttime will show the time of this change unless the old value is C
I am using VS2008 and I have a form which has a datagridview. This is for an invoice where I already have the user select the customer from a details view and want to have the items in the datagridview change based on what the customer selected. Then when the item is selected I want to have the price change accordingly.
So far I have the customer selction as well as the item combobox(not limited to cust items yet) appear, but I cannot figure out how to get the join of the 2 items (cust+item as the price varies from cust to cust) to change the price. Question is, is it possible to do this in the same datagridview, or should i try to just break this down some other way?
1) How can I make the text in RTB control to change without clicking on it (RTB control) again? I notice that the event handler is mousedown so its only occurs whenever the users clicks on the controls. But I really have no idea how to do that. Anyone can guide me how to do that???
2) How to make the RTB's Back Color to transparent??? Cause it is not supported. Or is it I use the wrong control???

I'm having a problem with a tab control in the program I'm writing. I have a tabcontrol with 2 tabs, tab 1 and tab 2. The user goes to tab2 and submits a db search for which the result is displayed on tab1. When the search is done all of the data displays correctly however the screen still shows that tab2 is selected and not tab1 even though the data from tab 1 is displayed correctly as content on the open tab. How can I ensure that tab1 is shown as selected and not tab2 ? I have tried to change the tab focus but this doesn't make any difference.

I cannot get a tool-tip to appear over a DataGridView object, although checking Microsoft's advice, it should do so, as I assume I have a DatSource property NOT set to 'Nothing' for the said DGV. ( I believe this is right, as the columns sort alphabetically, when I click the column headers ! As normal ) If I can get this to work, is there a way to get the underlying data from a Mouse Hover ( Cell Enter ) event, from the cell in question to modify the Tool-Tip's caption ?

I may have missed the solution to this problem, but in my database I have 2 columns that cannot be null and a system.NoNullAllowedException message is displayed if they are mt. I want to change this message to simply indicate that the cell cannot be null, instead of the huge message with all of the information which is of no use to the user. I cannot seem to find where to change this message. When the exception is thrown I would like to see the message say something like "Empty cell not allowed".
