I'm using VB 2010.I want a 2-column listbox control where the program fills the first column and the user can fill the second column. For example: The first column lists data fields (age, weight, eye color) and the second column allows the user to enter a query criteria (>65, =150, 'blue') which control I can use? Or maybe I need to create a 3-column grid?
View 1 RepliesIn my window application i have taken one combobox field with its collection as "amc", "war" etc. Now in my datagridview this combobox column is display as Textbox column, i want to change it to combobox with the above collection "amc","war". I have retreiving the result in datagrid through sql query, hence in datagrid edit column section we doesnot have that part to change to Combobox column.

I need to create a checkedlistbox that has multiple columns and each column has a header. Is this possible? I can't really find much on Google. Here's the headers I need:
Checkbox Title Existing path Destination path
I have created these columns to the checkedlistbox I have in my form, but when it is run the headers don't show up. Also the items I'm adding don't seem to abiding to the column widths I put in. Also with the code I'm providing below the items don't display as multiple rows, meaning each item doesn't get displayed on a new row, but in a new column.

Movie = New MovieItem()

I need a way to have 3 colums of checkboxes inside a checkedlistbox. I know i could do it with a panel, labels and checkboxes. But having them all in the control would be more convenient. I'm pretty sure there is no direct way of doing this, so i assume i need to create a user control. If you're not completely sure what i'm trying to create, i'm going for something that looks like this: [URL]
View 1 RepliesHow to add a checkbox column at first column of datagridview including column header?After adding, how to code to "check all" or "uncheck all"?
View 27 RepliesI am creating a system that records attendance of students. I designed it in a way that the user needs to load an Access Database into the system to populate the checkedlistbox, and then is able to check(tick) for whoever attends the class and click the Submit button.
Currently, i have my form able to Load from an MS Access Database to populate the checkedlistbox, but that's all. As for the Submit button, i would like it to check for selected items from the checklist and for every checked students, value "1" will be added to the "Attendance" column in the database for each particular record. Those that aren't checked would not have any changes to it.[code]...
I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.

Add persistence to multible DataGridView in terms of Hide/Show column and column width
View 1 RepliesVB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

View 1 RepliesIt seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

I have check the properties settings without any luck.

I have a program and I get time data from a sqldb and display it in a column in a listbox. What are the proper steps for adding the time as I iterate through the data in the column? I figure I will need to do some conversions on the time to be able to add it and display it as a total.

This is my programs complete code, the only problem is i want to fix the amount of decimal places that show up in my gridview. The problem is if i do this on the asp side the location of the column gets thrown off and the column is duplicated. I figured if i just remade the table on the asp side it would work only problem is if i remove the sql for that particular column the asp side column cannot get data.

I have several controls on aWinForm (VS2010) which are bound to an SQL database table via a Dataset, BindingSource and TableAdapter (all bindings created via the IDE). When i try to update the daatbase table with changes made in the form controls using:
Me.QuoteHeaderBindingSource.EndEdit()Me.QuoteHeaderTableAdapter.Update(Me.BurdensCRMDataSet.QuoteHeader)
I'm getting the following error message: Cannot set column 'SalesTeam'. The value violates the MaxLength limit of this column Now on the surface the problem would seem self explanatory and the solution quite obvious. However i'm not changing the 'salesTeam' data, so it's exactly the same as it came out of the database and consequently it must be the same length. the data is two characters, the database field is a Char(2) data type and the datatable field has MaxLength = 2. So i can't see what's causing the problem or what i can do to resolve it
I've tried changing the data in the relevant textbox to just one character, but it still throws up the same error I've tried changing the SalesTeam DataTable field to MaxLength = 4, but it still throws up the same error I've tried reconfiguring the TableAdapter, but it still throws up the same error
I know my code is good because it works for other datatables that other controls in the same form are bound to. I'm I doing something wrong or missing something obvious or has anyone come up against this before

I wrote a function to format numbers like this: 123456100,12 -> 123.456.100,12 (I have a function too, which converts numbers from this strings).Now, I have a dgv and a column with these numbers (or rather strings). The sort mode is set to automatic. If I sort the column, it doesn't work, because the values are not really numbers, but strings. But I get the same result (the sorting doesn't work), if I use the formatnumber function (this returns strings too).
I could use the programmatic sort mode and before sorting I format the strings to numbers, then sort the column, and then format the numbers like above. But this is a bit slow (the dgv has appr. 800 rows), and in this case, I haven't an arrow next to the column header text.is it possible to sort the column like a normal number-column with automatic sortmode?
I'm trying to create a datagridviewrow and add data to it at runtime. I want the row to have the cells correspond to the columns in a datagridview, so that when I add data to the cells i can call the column name (the columns are likely to change around, so i think the name is better to use then the index).I create the row using the following code:
Dim row As New DataGridViewRow
row.CreateCells(Datagrid)
and the column using the following code:
Dim col As New DataGridViewComboBoxColumn
col.HeaderText = "Reference"
col.Name = "Reference"
datagrid.Columns.Insert(0, col)
I would like to add data to the row via the following code (or something similar that uses the column name instead of the index:
arow.Cells("Reference").Value = Detail.Reference
However at runtime I get the exception Column named Reference cannot be found. Parameter name: columnName I have a sneaking suspicion that the cells cannot be accessed with the column name because the row isnt really attached to columns yet (the row hasnt been added to the datagridview yet. (I tried cloning the cells of a row and then adding them to the row but no success)?

Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.

how can i change this in code at runtime
