View 6 RepliesI have 2 tables Table A & Table B Table A has the table values that I want to be populated in a datagridview control.The challenge is that column 1 in table A contains an ID(foreign key) to a name field that is a located in table B. I need the datagrid to have the first column be a combobox that displays the names(from Table B) that are already in table A via the ID's, but reference the populating values from Table B. So that when you bring down the combobox you would be choosing from Table B data but populating table A with the ID and you would see a name there instead of an ID.[code] How do I populate my DS dataset with Table B? And how can I create a link to these two tables using a bound datagridview control?

I know I have done this before and as I remember it should be really easy. But for some strange reason I can't do it now and I am about to jump off the building.I will make it simple:Two tables, one is just a list of products and their code.The other table: "details" has a field named product. I want to store only the code there.In the second table's entry form, I am putting a combobox. This combo box should display the list of products, their names, but depending on which one is selected, the code is what is passed to the table "details". Currently If I set the display member to product and the value member to code it still pases the product to the binded data source.

the error display is "property access must assign to the property or use its value"
I have got this error and i want to know what property access is, i have deliberately not shown the line of code that it is to do with as i do not want to be given the final answer. I think i understand 'must assign to the property or use its value' does this mean that when setting something the object being set (as i am trying with font stlyle i will use it) font style must be set to bold or italic and then the bold font needs to be put somewhere?

Is there a tab property I can assign to make a given tab not only the "top" (or active) tab but also the left most or is there another way to do this?(It seems pretty straight forward to make a tab the top or active tab.)The requirement is that I've got one tabcontrol that contains a potentially large number of tabs. Each member tab has a right fair number of controls and dialogs.These tabs are all grouped by fours sequentially. For example, tabs 0-3 are one group, 4-7 the next group, etc.I'd like to control the display of this tabcontrol from a different tab control. This second tab control contains high level information about the 1st tab control as well as a lot of other things pertaining to all four tabs that the user needs to see as well.For example, if I've got 8 total Tab1's, then I've got 2 Tab2's.When Tab2(0) is selected, I'd like Tab1's leftmost item to be Tab1(0). When Tab2(1) is selected, I'd like Tab1(4) to be my leftmost tab in Tab1, rotating the lower 4 out of view for the time being.
