View 1 RepliesI am having problem with datagridview. Actually I have created datagridview control used to display the data using sqldatareader. My problem is that How can I fill the data in textbox control when user selects the row in datagridview using coding. For e.g. my form is having a) Datagridview and displaying values of columns: Name, Address, City, State etc and textboxes: txt1, txt2, txt3, txt4. Now if the user selects any row from datagridview the selected value of Name is filled with txt1, address is with txt2, city with txt3, state with txt4. I am directly dealing with database with using DataAdapter.
View 1 RepliesI am having trouble in allowing the user to select the row in the datagridview.
I managed to include the checkbox column in the datagridview but i do not know how to wrte the code such that when the user wants to update or edit the data in the checked row, he just have to check the affected rows checkbox, can be one or many, and then click on ok button, which will then lead him to the data updater form, allowing him to update the data.
Currently i have the below code which can populate the checkboxclumn only.
dbProvider = "PROVIDER=MICROSOFT.Jet.OLEDB.4.0;"
dbSource = "Data Source = '" & Form1.TextBox8.Text & "'"
con.ConnectionString = dbProvider & dbSource

I created Dataentry forms. In the form there are so many controls like DropDowns and textboxes. I am using Access database. Now I enterd the few records into the controls, and these records are saved into the Database. But now if i enter the any data which i recently saved in the database to the textbox or any other control then the remaining controls should be display the related data.
For example i have 4 controls in my form one is dropdown and 3 are textboxes. If i select the data in the dropdown then the remaining 3 textboxes shows the related data. How can i dispaly the corresponding data to the other controls?

View 2 RepliesHere is my problem: I have a DataGridView and I am adding a new row. In a particular cell, I have to check that the user does not enter existing values in the related table. That is, the value of that cell must be unique. If the user enters an existing value, the application must:
- Show error message
- Clean the cell
- Put the focus again into the cell, to allow the user to enter another value.
Would you know someone do this?

View 14 RepliesI have a datagridview showing data from an Access database. I have dragged the datagridview from "Data Sources" window - and not written any code. In bindingsource I have choose to sort on an autonumber field. Is it possible to let the user use the mouse to change the order, and the database to remember this the next time the user starts the application.I guess I have to have a number field in the database, and write code to change the value in number field as the user change order - and then save this back to the database? Does the datagridview support changing order by mouse at all?

View 4 RepliesI am sorry to keep bothering you about this damn DataGridView control ... As you might have noticed I am having a hard time with the DataGridView control ... My latest problem has to do with updating the data base file (Access) through a DataGridView control .
Up to now I have managed to successfully edit an entry in the DataGridView control and moreover to successfully update the data base file itself .
The above form and its code work fine . The problem starts when I am trying to run the code of the Update button from another form .
You see , I have another form , through which I change the contents of some of the cells in the DataGridView control (back in Form1) . What I want next is to simply update the data base file itself , just like I was doing with the button in the first form , after I manually changed the cell in the DataGridView control .Thus , on the second form I have a button with this code :
Form1.Button1_Click(Nothing, Nothing) (of course the Click event is declared public)I have also tried :
Form1.Button1.PerformClick()
but still nothing ...Although Form2 successfully changes the cells back in Form1 , the data base file itself does not get updated ...If I manually press the Update button in Form1 I once again successfully update the data base file , but I want to do the whole thing by calling the Update button from Form2 .
Asset Database, with DataGridView that is populated with desktop and laptop PC's by 'Office' and 'PC Type' (Combos). You can double-click a row to open an editing screen to edit the PC details eg: assigned user, purchase date, serial number and so on. The problem

I'm using Visual Basic 2008 in Windows 7. I've added a datasource to my project and dragged an element, a sort query, from Data Sources onto my form. It automatically created a DataViewGrid and placed this statement in my form load event: Me.SortBillsTableAdapter.Fill(Me.DoBills_2009DataS et.sortBills). The datagrid view shows all the fields/columns. When I preview the data element from right clicking the element, selecting Preview Data, and click Preview in the Preview Data dialog box, the data appears. But it does not appear when I run the app. The datagridview is empty. What am I missing to get the data to display in the grid at run time? I did notice that in the properties for the dataviewgrid the databindings property is empty. Is that right or am I supposed to do something there?
