I need to select all the comboboxes on a form with a for each loop. I have about 19 comboboxes and I need to select each one. I tried to do for each box as combobox in me.controls But that gave me an error and i now tried this: for each box as control in me.controls if box.name.contains("ComboBox") then ... end if next That selected only the comboboxes but the problem is i need to access some data that is specific to comboboxes (aka the selected item(s), if its blank) but those properties are not present since "box" is a control, not a combo box.
how i can get the grid to select a row by clicking on any cell in the row?
The only way i can do this at the moment is by setting the AutoGenerateSelectButton property to True, but this adds a column to the grid with a crude "select" hyperlink and only selects the row if the word "Select" is cliked on.
Whenever a row is selected in my GridView, I want to take the ID field of my gridview's dataset and form a unique URL with it (use a ?id=1234 parameter). In the Page_Load event I have the following code:
I have aspx gridview with checkbox on evryrow, what is required is whenever we check any of the rows, a query should be launched to change the specific agent -each row consist of agentID, Pass, Status- to Paid Status. using javascriptWhat I need to know is how to loop to get the Checked row and get the ID of the row checked so that I can get THe ID of the Agent in thos row so that I can update its status.using javascriptI found something similar on stackflow:t GridView selected row DataKey in JavascriptBut it is not my case, what is needed is at the check of a checkbox a javascript function should launch through which I could update the selected row in grid view after having the index of this row and this all to avoid refreshing the page.

I want to populate a checkbox field in a gridview.
I am using the Checked='<%# Convert.ToBoolean(Eval("Inactive")) %>' statement but the issue that I am facing is that in the database some records contain NULL for Inactive. If it encounters a 0 or 1 value it works fine but if NULL it throws an exception.
Kindly guide me how to populate the checkbox so that it should be unchecked even if the field is null.
I'd like to have a backgroundworker process data that will eventually populate a gridview in my windows form. I need to use a backgroundworker because the process takes a little while, normally causing the program to slow/freeze until it's opening and streaming connections.. So, I'm using a background worker to perform these methods.How can I take the data from the background worker (on a separate thread than the UI) and use it to populate controls in the UI?
It has been so long since I have coded a page in VB. For the life of me I just cannot remember how to do this. I have a GridView on an ASP page. Each row has a comment ImageButton. I already have the gridview and text box wrapped in a UpdatePanel. The gridview shows all of the correct information. I just need to add some code to populate the text box with the comment when a user clicks on that row's ImageButton.
The comments are stored in SQL 2005 DB if that makes a difference. Should I shove the comments inside a hidden field of the gridview or is there a function that will allow me to query the db for that specific comment. End goal would be to not refresh the page if possible.
If I used a generic list Class to hold data objects that I am pulling from SQL Server using Linq to sql to populate a datagridview would I need to make any modifications to the datagridview control to accomodate multiple columns or would I need to make any modifications to the generic list class to accomodate the multiple columns in a row that is typical of a record in SQL Server? And one more thing which I believe is the easy part. To bind the list to a datagrid view would I just use the datasource property of the datagridview control.

I have a system that I need to connect to an access database. Once connected, I have a form that allows a new customer to be entered into text boxes. I need to then take the data in the text boxes and save them in the database table.On a similar note, I have another form, where the customer details can be updated. Basically, by searching for a Customer reference number in the database, the form is populated with the table data. Then I want a button that will update/overwrite any chages made.
All of the columns populate correctly except for the Long column. It returns a null for all rows. I have tested the SQL statement in Toad and it works perfectly. how to get an Oracle Long data type to populate in a gridview? This is driving me nuts

So in windows explorer, the form pops up and then the user keeps clicking on files and I want these file names to be added to the listbox.
