View 3 RepliesI have Grid view on my WebForm, a Checkbox placed in a Grid view,i have 70 field/column values right below grid view,when ever i select the GridView Checkbox ,entire record should be displayed in field/column values.How can i acheive this please provide
I'm a little bit confused. I'm trying to pass in some values to the associated database table from a gridview.I have a databound gridview fetching values from a database, on each row a checkbox is generated to each item in the list. For exapmple, the gridview fetches data from the table "Interests" and prints it out on the page, and the visitor is supposed to check in those checkboxes that corresponds to his/hers personal interests.When clicking submit, the Table UserInterests in DB gets the values:
UserID = 1 (gets a unique ID from a previous step)
InterestID = 45 (Shopping)
UserInterestID = (auto increment)
What i need help with is how to check if the Checkboxes is checked or not, and how to pass in the true or false to the db.I have read Step 2 in this tutorial, and it seems like my solution will be somewhat similair to this:http://www.asp.net/Learn/data-access/tutorial-52-cs.aspxKnow it's a tricky question when not knowing the structure of the project, but i'll be glad for some pointers and tips!

View 2 RepliesI have a gridview with my inventory showing. Is it possible to add a checkbox to the gridview and when the user selects that row or multiple rows, this information can go to an order webpage. I'm a bit of a newbie so any examples in VB you can offer would be great. Seems simple I just don't know the process
View 16 RepliesI am displaying a checkbox in gridview in itemtemplate. It is displayed as checked when the database value is 1 and displayed as unchecked, if the database value is 0. My requirement is when a link button in gridview is clicked, the checkbox, if it is checked should be unchecked and viceversa. Also, I need to save the corresponding values to database. How is this done in the click event of linkbutton. Is there any other method.

First off, sorry if this is in the wrong section. I have a gridview that loads from a SQL database. It has three columns, the first being a template column with a checkbox, the second being a name from the database, and the third being a field from the database related to that name. (the third column is empty). I want to be able to click on the check box in each row, and automatically have the third column populate with data that the user can select from a drop down list at the top of the screen or something. I am using VB, and I basically just need a way to make this checkbox, add a value from somewhere into the database. (Also, I know that I can just use Edit in the gridview to change data, but there will be a long list, and that way gets quite time consuming) I hope this makes sense, if not I can try rewording it.
