I have a Datagridview with a database attached , but I want to search the the collums by picking the collum I want from a combobox, writing in a textbox and pushing a button and the arrow in the database will move to the row if anything is found, BUT I don't know how to add the collums from the database to the combobox and do the search using the button.
I would like to implement a code which executes what a user selects from the combobox and display related data from the access database on the datagrid.I have managed to connect to my database.How do I connect the combo box action to display information on the datagrid?elow is a code that am using to read the contents of my table from the database and display it on the datagrid.
I am a new one to vb 2005 and I have no idea to get the datagrid filter view option.I developed a new program which have an datagrid view.I want to filter the data based on the 3 thingsthe first one is the "dates between start and end with 2 datetimepicker controlhe Second one is 2 of the filter combo boxes.For ex: it should filter the data between the two datetimepicker
I have a datagridview. The database is unbounded. When I display the database in the datagridview. I want to search for a value in a datagrid view. For this I want to add a textbox. The user enters a value in a textbox. Then the search could be able to search for the value entered in the textbox in the datagrid view .
I started a forms solution in VB 2008, created a datasource to an access database (2010) and used the datagrid view to display the data. 3 fields in the access database are lookup fields with 2-8 values each, typed in by me, since the linking to other fields did not work. This is not working either. When I change the column to combo-box or not, those values, typed into access, are NOT showing up in the datagrid. the combo box has its drop down arrow but the value fields are empty.
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.
i am trying to bind the combo box through details view in vb.net but unable. i am making a login form and i want to display two values e.g usertype admin , employee in combobox but when i run the form it doesnot show me anything in combo box although i have selected the true binding source and display member but still unable. Another problem is in my form load event if i left this line written
it not only shows me the combo box values but also types in the user name and password which is saved in database. All i wana do is when the form gets loaded ..user name and password field should be bland but the user type field should show two values.

I created a filter for a datagrid using a combo box, but every time I select an item from the combo box and there is no data for that filter I get the following pop-up error during debugging:Index -1 does not have a value.Here is the code that I am using:
1 Private Sub RYAN3estimatesBindingSource_CurrentChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RYAN3estimatesBindingSource.CurrentChanged
I need some advice I have a bound datagrid and a bound combobox lookup on a form. What i want to do is filter the combo box so it only shows the items left that are not in the datagrid already.
I have managed to achieve this already.But when the program runs, and there are items displayed in the data grid the combo box items are now filtered.The program crashes as it can't display the combobox item as i have filtered them out. The program runs fine if the datagrid is empty (IE combobox items not filtered). But as soon as there is a record in the datagrid when i save the database and refresh the combo box the program falls over is the items it is looking for is not in the combo box items list.
What would a work around be. I have thought of a separate combo box that is hidden and use the datagrid combobox events to show it in the correct position.Just to be tedious the displayed item is not the stored item value
* How can I filter or re-bind the source of the second one as the first one value changed (Both are in the same datagrid).>> So as I select an Employee I need the second one gives me just the specific departures of the desired employee.Where I have the (Employee_No) field connect the two tables related to each one.
Using Visual Basics Express 2008, I am trying to add items to a combo box FROM column headers in a datagrid in a separate form. I have written the code to create the datagrid from an external file but can not get the headers of that datagrid to populate the combo box in a separate form.

How To Avoid The Closing Of A Combo Box Popup Window In Datagrid? I was trying to block the closing of a custom combo box popup window in my custom DataGrid. The popup window comes by pressing F4 or ALT+DOWN keys which is getting closed if I press the down arrow for the first time after showing the first value in the combo box as selected. Next time onwards, if I press the F4 key and down arrow, I can move to any item in the popup window and select the item using keyboard and in that case, the popup window is not getting closed till I press the ENTER key or selection using the Mouse. Is there any specific reason for this behavior or something is missing in my code part?
I am still having issues with the combo box. I have the correct query. I have four tables in MS Access. I need to create a form in Visual Basic that has a combo box and a datagrid. The selection from the combo box will display all relevant information about that person on the datagrid. For example, if I select John Doe (from the combo box) the datagrid should display: [Code] How do I add John Doe to the combo box and link this query to it, when upon being selected, it displays the result in the datagrid?
I have a datagridview that is connected to a table from my database. It displays all the records from that table. The question is this, how can i put a checkbox column on my datagrid for me to be able to delete multiple records from my database? I am using visual basic .net 2005.
how to filter the datagrid view? what i mean is, the data that will only show in the datagridview depends on the date selected on the DateTimePicker(dtpDate) example if the value of Date is march 20 2012 the data that will only show on the datagrid view is the event that is save on the march 20 2012. also to arrange it ascending based on time.

I have this form for inserting and preview of data (access db) - VB 2008 express. Form is on picture 1. Now I want to print out details from this db (see word screen shot how I would like it to be, not exactly but something like that). Name of document should be form name and text is from db.
i'm having with a problem to refresh my datagrid view. I have 2forms and a database create from msaccess2010. This programme is too simple, in form1 requesting a costumer name and save button. After being saved, it'll show form2 which is database in datagrid view. Yes, in first save the name of costumer are being shown there but after i close (which is 'hide' actually,i cant use 'close' due to particular reason) and reinsert the data in form 1 and save it,the second data are not being shown in form2. So my question is,how can i make the data refresh(by form load or button refresh,any of them)?
