Bind An IEnumarable Collection To A Datagrid (items Of Variable Contents)?
Aug 11, 2011While working with an excel file (.xlsx), the data I get from it is an IEnumerable(of Dictionary). When I bind this to my datagrid, I get the problem that I only see 2 columnsI've been tracing this problem and discovered that in the first row in the excel, there are only 2 values (cell C and D). I think the binding to datagrid looks at this first row to create its headers. This results in my datagrid only showing columns C and D.

VS 2008 Datagrid To .txt (array)
Mar 18, 2010I'm fairly inexperienced with VB but have been trying to get "save" functionality out of a program I'm trying to write. Basically I have a Datagridview and I want to write each line from the grid into a .txt file. So what I've been trying to do is use Datagridview.Items and then variables as column / row indexes to move cell by cell left to right , writing each cells data to an array which also increments along the way. Then using WriteLine to write the array to the text file, zero'ing all the counters then starting all over again for the next row.... make sense?

Using Variable In Array Variable
Feb 14, 2012if i generate a label dynamically i can change the text as followed, variable is a string: Form.Controls(variable).text = "test" I now have a sub that will create some and will get some information out of arrays. I have a lot of them. I only want the function for tat specific array. I do not want a case or if. Thats why i was wondering if i can use a variable in the array variable. [Code] But instead of TestArray being hard-coded i want it to be replaced with Shelf. So whatever gets send into the sub will change the array that i'm using. Is that possible some how or is the way totally wrong?

DataGrid View Changing An Array
Apr 26, 2009I have a table of 51 data points all numbers between 0 and 8000, i have stored the data in an array of ushors's, and on my form i have 10 numerical text boxes, So that the user can change the values in the table every 5th value. Using the value changed event the program then re-calculates the values in-between.
What i would like to do is show the table in a data gridview and allow the user to change the values in the array using the datagrid view, i know how to create a table but not how to link the table, so that it can change the values contained in the array.
Below is the code i am using to create the table:-

View 4 RepliesVS 2010 - DataGrid Custom Class Array
May 14, 2012I am working on a project which lets the user edit the students in a certain group using a datagrid. First I created a class called student and then I created a student-array. Displaying the students in a datagrid works fine. On form-load, I change the datagridview.datasource to the student-array. The datagrid has 20 rows by default (Public dbstudebt(0 To 19) As student). When I edit an existing student everything works fine but when I fill something in in an empty cell and press enter or tab to confirm and add a new student, it just clears the cell and nothing happens. So basically, editing existing studs in the datagrid works fine, making new student doesn't work at all as those cells are always cleared immediately.
