I have a DataGridView control that is bound to a dataset that I set up in design mode. This grid will contain addresses for a client. The relationship is 1 client to many addresses. So, when the user selects a client, I wish for this grid to populate with only the address records for that client. How do I set up in code a way for the grid to recognize this?

I got a pizza shop and the assingment is to create a application which allows the user to take a customer's order... I have a combo box filled with all of the items you can order (data from an access file)... and I need to have it so that when you select an item, it shows up in a text box below... I keep getting an error message saying you can't convert datarowview to string..

On the form load event i want to populate my ComboBox1 to display unique items directly from the DB. For that i have set the DataSource property of the ComboBox1 to the selected field. On the ComboBox1_SelectionChangeCommitted event i have set the filter for the DataSource which is working fine.
Now when i select an item from the ComboBox1 i get the filtered result in DataGridView but when i again drop down the combobox i see nothing other than the last selected item. Why is this happening? Is there a better way of populating ComboBox with the items directly from DB with default selected value as null?
I have a data grid, and I am pulling data from a mysql table. How can I populate my grid with the data? I also want it so when someone double clicks the item it will perform an event. How can that be done as well?
View 3 RepliesI use Vb 2003 and SQL server as the DB. The SQL server is on the server. I use a RS to populate the Data grid. But for some reason the it wont populate and I will have to get out of my program and then load it back on for the RS to populate the grid. I tried putting a message box just to give the RS to receive its data from the SERVER but still it wont work. It does not happen all the time. I don't think it is a problem with VB or SQL SERVER, I think the Server is not returning the request.
View 11 RepliesI have DataGridView control which i populate with some rows from the database the database table which i work with changes a lot so every 30 seconds I re-query the database to check if there is new record or existing record changed or record deleted, I can't clear and re-populate the grid view because people might work with it and they're might doing some changes in some rows.
so if the row was changed i just want to update the changes in the existing row without recreating it, if some row deleted i want to remove it and if a row was added i want to add the new row.

View 2 RepliesI created table named "tb_sale" using ms access 2007, it has 5 columns (date, product, qty, price, total)
I created a listview which has same columns with tb_sale (date, product, qty, price, total) Then, I dragged a datagrid (tb_saledatagridview) from tb_sale to the form, hoping i can insert multiple records from listview to tb_saledatagridview.
I manage to insert record from listview to unbound datagrid, but not for bound datagrid. code that I can use to insert and save data from the listview to tb_saledatagridview.
I have a datagridview which is bound to a table in a database. In said table, I have a field called Date and a field called Time, among other various fields. By default, I see that VB.NET attempts to help me by formatting the Date and Time columns for me, however I would like to do it my own way. I checked the columns' DefaultCellStyle fields and found them blank. Apparently, its current behavior is defined elsewhere. How would I go about removing the default formatting that VB.NET put in place to make room for my own?

I'm having some problems with a data bound datagridview.My current scenario is the following..The itemSetup has tree properties {ItemNo, CompNo, LocNo}(compno locno are not required)I have a datagridview with a datasource list of itemSetup And this has two comboxes cboCompany that is bound to a list of company the selected value is bound to compno. cboLocation that is bound to a list of locations the selected value is bound to locno the location class requires the compno to create the list of location the problem I run in o is that the when the compno is Nothing the cboCompany throw a datagridview_ dataerror when the form is loaded en when a item is added it looks like the binding of the combox runs later then the value is set.

I have a DataGridView on a form in VB 2005 Express, of the 10 columns i need on this DGV 6 of them will be pulled from an MSSQL DB and 4 of them i need to manually enter. One thing i have going for me (i think) is that the 4 manual columns have the same data in each row.I have been filling this DGV using a datatable, but i am not figuring out how to add manual columns and databound ones in the same DGV. My column layout would look like this:[code]some one please explain to me how i would do something like this. if you can include the datatable definitions also it would be a big help, in order for me to verify that i am at least doing that the right way.
View 1 RepliesI have an editable datagridview that's been databound with dataadapter and datatable, and a normal button on a form. When i edit the dgv's cells and click the save button it fires the datagridview_cellvalidating event and if the cell validation is correct it updates and saves the current record to the datasource. Also, before save it commits change in any cell under editing.But when I use a toolstripbutton to do the same work, though it saves the dgv records but doesn't update the current change i.e. it saves the old records that are being fetched when the dgv was populated first during form load. Also, clicking the toolstripbutton doesn't fire datagridview_cellvalidating, datagridview_rowvalidating etc events.
What it seems to be is it's not commiting the change in any cell under

My DataGridView is not sorting my date column correclty and it doesn't seem to be sorting it by String either. The column is bound to a date property, all is done using the designer.The set which I'm viewing it on is 424 entries long, there should be two entries for each date and they should be next to each other (regardless if sorting by date or string)The last few dozen entries are sorted correctly but the initial entries are not.Initially every second entry at the start is correct. Here is an extract if some of the sorting it does.(The beginning of the sorted grid is on the left, and the end of grid is on the right)
View 1 RepliesI've inherited a form that has a DataGridView that is bound to a dataadapter and it is connected to a binding source. Within the DataGridView is a combo box that is bound to its own bindingsource which basically just calls a stored proc to bring back the possible values for the dropdown combo control
With a blank new row and sometimes even with an existing row, this value for the combo box can be NULL which is a legitimate value for it if no value selected. Problem is everything is so tightly bound if the user mistakinly clicks the dropdown then a value is populated and there's no way to get back to NULL
I've tried to catch the mousecelldown event and others to try to catch this before a value is selected but the Cancel=True doesn't work - I can catch the event but don't know how to return the cell to unclicked or reset it to NULL or pre selected value if NULL I know how to at a new row with the datatable and then set the combo datasource to it and I have my null blank value but with a tightly bound control how do I add this row?
I am developing a Windows application in Visual Studio 2005, V2.0 using VB.NET. I am coding part of an Emergency Response Information System. On my form, I have two combo boxes (cboBaseStationID and cboPriority). I am trying to populate the datagrid with records from my database based on what is selected in both comboboxes.
For the first combobox, the user selects a name so the datagrid must only show records with that name. For the second combobox, this is a little more complicated. There are four emergency priorities in the combobox that the user can choose - 1, 2, 3, 4. In the database, there are different response teams (to be dispatched to these emergencies) and each response team has a grade of either 1, 2 or 3. [Code]
