I have one table from where two comboboxes get their drop down lists, showing info that has been entered into the table (boxes are bound to the table columns I.E City (Box1) and Country (Box2). what I would like to do is if a city is selected in box1 then box2 will autofill with the country name.
View 3 RepliesI want to learn how to populate a combobox so if a vlaue is selected in another combobox then it will be invisible for selection. You can NOT use combobox1.items.remove since my box is bound to a datasource.So I either need to create a new query and adapter and bind the combobox2 to that query, or fill combobox2 from combobox1 minus the selected item in combobox1. Either way I need some help writing code correctly.I have tried a few different ways but not succesful, I was probably on the right track a few times but I am still not very proficent in code writing.This is the code I have written so far for my program, I deleted all my attempts at remove selected item since none worked and were just confusing.

In my datagridview, I want to be able to change the value of comboBox1 depending on what the user selects in comboBox2
I had this working correctly, however if I move onto a new line in my gridview and select a different value in the second row it changes the previous row also. For instance, on Row1, if comboBox1 = A, combox2 = B
Then on Row2, if comBox1 = Y, comboBox2 = Z
However, when I change Row1, Row2 is also changed to reflect what was chosen in Row1. Is there a way I can tailor it to each specific row?
I want to auto fill a range like this:
In Sheet1!A1 i have the formula "='Sheet2'!D1"
In Sheet1!A2 i have the formula "='Sheet2'!H1"

Now the Sheet1!Ax increments with +1 value; The Sheet2!D repeats again with D, H, L but only with a +4 to all 3 of them

I am Working in vb.net .The only i found is C# .. "The fuction you want can be called "cascade comboboxes", i.e. there're two comboboxes and the items of the second combobox depends on the selected item of the first combobox. The basic way to implement cascade comboboxes in a DataGridView is to handle the EditingControlShowing and CellValueChanged event of the DataGridView. in the EditingControlShowing event handler, if the column in question is the second DataGridView combobox column, change the data source of the editing control (DataGridViewComboBoxEditingControl) to another data source and filter the new data source.... In the CellValueChanged event handler, if the cell value under the first DataGridView combobox column is changed, clear the cell value under the second DataGridView combobox column in the same row.."
The Problem is this: 2 ComboBoxColumn already with their dataset (via propretries of datagridview design) and the DGV2 is a detailed datagidView Reffered to a Master which is another DGV on the top of my Form. So in DGV2 the first ComboBox 1(column 2) displays data .According to this Data the other ComboBox2 (column 3 ) filtered. The problem is that when you select more than one time the same value of the Combobox1 and then you try to select another value the displaying data of the ComboBox2 dissapears.
keep the values of combobox2 always visible..

View 4 RepliesWriting a little program for my wife and thought it would be cool to have the calendar auto select the next day of her choice when she opens it. Example it's Monday and she opens the program to make notes about things for her girly get together every Thursday. Right now she opens it and has to select the next Thursday first to get the date.
What i thought would be cool is if the program picks the next Thursday for her, in the future the night may change to Tuesday so i don't mind hard coding the selection for now as it wont change all the time.Is there an easy calendar or date picker routine available for this or is it a roll up the sleeves, i searched and not finding anything.

I'm working with referenced VB6 DLL's. The problem is that the results of a method/function call are not the same. Below the code examples:
First VB.Net Dim Validations() As String myErr = myEntry.ValidateLine(Validations)
When validation fails, the string array Validations is filled with the error description string. I've tried to accomplish the same in C#:
private string[] valArray = null;
sdkError = sdkEntry.ValidateLine(valArray);
Does anyone have an idea why I can't get C# to fill the string array? Additionally, the function in VB is called with ref to a System.Array ValidateLine(ref System.Array ValErrors), perhaps it has something to do with this?
