View 4 RepliesI have a vb.net app that uses a table from an ESRI shapefile. The user the datagridview is populated based on a query. Now I need the datagrid to sort on three different fields, as in Street Name => Address Number => Unit. (I can sort on one field)
I've tried to use code samples on the IComparer class but am just not getting there from here. I may be missing something really really simple. (so I attached the code sample I'm using).
My 'workaround idea' is to add a column when the datagridview is populated and concatonate the three fields together. Then I can sort on that new field. I can add the column, but haven't figured out yet how to concatonate the values in the three fields into this new one. And I'm concerned about speed.
I am displaying data in DataGridView. When I am just adding a record at runtime, the new record gets add, but previous records are getting displayed two times.I tried to remove the rows which are displayed before adding the new row. But then new record is not getting displayed.
View 1 Replies1. I have a DataGridView box, that is connected to a MySQL database via the 'Data Source'. I am trying to do the datagridview1.rows.add("info here"), however i receive an error i cannot do this programmatically. I DO know the code to post to MySQL via the "insert into" la la la.However, I was curious if I can do this via the datagridview a bit..easier/simpler, such as a "datagridview1.rows.add(stuff)" sorta thing.

View 1 RepliesI'm trying to connect a VB application (2010) to an MS Access DB by adding a data source from the data menu but I receive this error message "The connection you selected uses a local data file that is not in the current project.Would you like to copy the file to your project and modify the connection ?
If you copy the data file to your project, it will be copied to the project's output directory each time you run the application" and the options are (yes , No , Help)
If I choose Yes I will not be able to make the application 'device independent ' since it will not be copied under the bin , and if I choose No , changes won't be applied to the DB

I have a datagridview and two datatables. I am comparing the information in the two datatables. Now, if the data exists is datatable2 but does not exist in datatable 1 I would like to add a row to the bottom of the datagridview and fill in the necessary information.
Can someone give me an idea of the necessary syntax that I will need to accomplish this goal? Also, I know this post is a little vague and if more information is needed to answer the problem I can give it.

I would like to add a row into a DataGridView: The first column is a string All of the middle columns are of integer type (for sorting) The last column is a string All the values above are passed to the Sub by a array (currentRow) of type String. However, the middle values have to a go through a type change to type Integer for sorting The following Sub works perfect except: The number of items in currentRow (the columns) may vary Then the hardcoded dgProduction.Rows.Add() code at the bottom with not work properly because it is fixed with a total of 6 columns. note that the length of currentRow() will not vary during the population of a single population event. Instead it may vary once I have cleared the grid and click on a different date. So all the rows within the grid will have the same number of columns.

I have a DataGridView that is bound to a DataTable. In this DataTable is a column that contains an image path location, ie; c:imagesmoon.jpg. In the DGV, I'm only displaying 2 columns, the "Name" of the image and the "Image" itself, which basically is the path information. how do I get the image to display in DGV Column? Because even though it's bound...no data comes up when I run the app.

I'm having an incredibly frustrating problem with datagridview that seems like it should have a very simple solution, but I haven't been able to find it yet.I have a form with a datagridview on it that is only usually 1 to 2 rows long but can be much longer. So when the form loads it populates the datagridview with values for however many rows there should be, and there is a blank last row. On the column header on that last row is an asterisk. If you click on the asterisk or anywhere in the blank line, it adds a new row where you can enter data, however, the blank line with the asterisk does not move down to be under it. In fact the asterisk stays on that line, and if you click anywhere on that same line, it adds another row, placing it on top of the one that was just added, and this can happen forever. I have a sub that refreshes the whole table and repopulates, however I can't run it in the new line code with an "Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function." which I can't seem to get past. If I exit the form however and come back in (it runs the refresh on loading), now all the lines that were added show up, with a blank line with an asterisk at the bottom.
View 1 RepliesI have an Access database with a Parts table. I'm using tableadapters in my project. A datagridview on my form is filled manually in code. One column of the DGV contains a columntype of combobox. I've got a bindingsource on my form whose source is the Parts tableadapter. The combobox column is tied to the bindingsource and is displaying fldDescription.
The part descriptions can be changed by the users, but the original part description is saved in another table that is used to fill the grid. If part "widget" gets changed to "widget, large" I can no longer display "widget" in the combobox of the grid. I need to know how to be able to add it to the bindingsource so I can display it in the combobox. I don't want it saved to the Parts table though.
I have a Datagridview with a bound datatable in it. Then I add a check box column to it.
When I click the headder of the DGV, it sorts the bound columns, and clears all checked checkboxes in the checkbox column.
How do I bind the checkboxcolumn to the rest of the table?
