suppose that if we search for value AROUT which is in cell nomber 3,5 and 7 when user hit the serch button first time then data grid cursor should move to the 3rd cell and when user again click search button then datagrid cursor should move to the 5th cell and when user click search button third time then datagrid cursor should move to the 7th cell i have tried many combination with FOR loop and IF condition but with following code i am able to search the string only once obviously if condition does not allow me to search a value more than once .the code is
for i as integer=1 to 90
If DataGridView1.CurrentCell.Value<>textbox1.text Then
DataGridView1.CurrentCell = DataGridView1.Item(0, i + 1)
End If
Next
The problem is when I search through a textbox and nothing matches the search query, I accidentally click the column header which is the lastname then the error "Object reference not set to an instance of an object." pops up.
The highlighted part of my code is the text closed in quotation marks.
"If dgvStud.CurrentCell.Selected = Nothing Then"
btnEdit.Enabled = False
btnDelete.Enabled = False
Exit Sub
Else
btnEdit.Enabled = True
btnDelete.Enabled = True
End If
This code is under my dgv cell click event. Here is a screenshot for the column header where I found the error. [URL]

View 2 RepliesI've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.

I have on my form two datagridviews that correspond to the same table. They are both databound. They have been created automatically through dragging them from the datasources windows.One is datagridview and the other datagridview1. When ever I navigate through a datagrid the corresponding row on the other grid changes as well. I do not want this. Also I want to be able to fill and use each datagrid indepentent from each other. To fill a datagridview on load I use this code
Me.AllServicesTableAdapter.workstation(Me.Database2DataSet.AllServices)This code does not let me choose which datagrid to fill.
I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
what are the differences between the WPF Datagrid included in the .NET Framework 4.0 versus the Datagrid included in the out-of-band WPF Toolkit? I understand that the toolkit version was released first, and targets the .NET Framework 3.5 SP1.
I needed a WPF datagrid quick and have utilized the toolkit version in my applications. I'm considering moving the application to .NET 4.0 and am wondering what the pros/cons will be in changing out my existing datagrids for the new ones.
I have one data grid which contains a column which contains long string values. When I edit it, the text box which appears is very small. I want to increase the length of text box.
