View 6 RepliesI'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

After user entered a value into textbox (for example 4), datargidview must be create automatically(number of datargidview's columns and rows must be textbox value). And, user enter some values that among 0 and 1 into datagridview's cells. So i want to assing these values (values that are written in datgridview cells). For example, if user enter 0.25 in datagridview's cell 1, and 0.34 cell 2, 0.67 cell 3, and etc, in this instance array(1,1)=0.25, array(1,2)=0.34, array(1,3)=0.67 must be assigned. i hope, i could understand :) i illustrate this example below. i want to assign such as indexs that is written into following example table.

View 3 RepliesI'm using the follow code to grab values when a row is selected on my datagridview:
Me.DataGridView1.CurrentRow.Cells(0).Value
in this case for the first column. I am doing this for several columns. What I would like to do is switch to specifying the columns by name so the code won't have to be changed if columns are moved around. I have tried several things that didn't work. Can anyone supply me with the code to retrieve the value of a column on a selected row by the name of the column?
I have a simple DataGridView that I fill in with data from a SQL server source. The query is fairly simple and after the grid gets populated I manually add several new columns and then iterate through each row and fill in the columns with appropriate data. all that works well. but now when i click on a column header to arrange the data the data in the columns that were manually added disappears. is that suppose

View 2 RepliesI am workinng on an aopplication using the DataGridView.My intent is that the DataGridView is displayed with four columns, the user clicks on a row in any column and the complete record for the selected item is displayed and the DataGridViewis no longer in view.
The code to do this is in the event "dgvCollections_CellContentClick" and the function works exactly as I want it to.The problem is that when I want to sort by a specific column I click on the column header and not only does it sort , it calls the 'CellContentClick' event and the details form is displayed, which I do not want to happen.Is there a way around this problem other then using the "dgvCollections_CellContentDoubleClick" event to select the detail? This was what I did as I sterted this project and I found that the double click was very sensitive and often did not work. The single click is much better for the eventual user.

View 18 RepliesI�m migrating a project from VB6 to VB.NET 2010 Express. Im replacing msflex grid with datagridview. But i�m not quite familiar with it. Im not using datasource. This will be done (far) latter.
So far i�m filling datagridview by code reading a recordset from mdb. Works fine.
The problem is that, I have defined the columns at visual studio designer mode, without using any code. When I open my mdi child form for the first time it works. But If I close this form and open it again a error occurs because it loses the defined columns.
how to preserve columns defined at design after close de form?
My MS-Access database contains 30 "table" files with identical formats (e.g. Composer, Arranger,Lyricist, etc.) and I use a common VB.NET form and DataGridView for displaying and editing any one of the 30 tables. When a user makes a menu choice, the menu program puts the file name and its first field into two global variables and then shows a form that contains an unbound DataGridView. This other form then loads a dataset from the appropriate database table and programatically binds the DataGridView to the DataSet. (I clear the dataset before filling it.)
All goes well and three DataGridView columns are displayed for the first time. However on subsequent operations, the DataGridView retains the columns that were previously generated along with their column headings (but no data) and I get six DataGridView columns. On the third operation I get nine DataGridView columns.
I have unsuccessfully tried to obtain a count of the number of DataGridView columns so that I can remove them from the DataGridView but it always gives me a column count of zero.How can I accomplish the simple task of removing all columns from the DataGridView?
