Forms Data Controls :: CheckBox In GridView - Replace With Images?
Jun 15, 2010
I am relatively new to asp.net and program using VB. I have written the following code to try and replace ReadOnly CheckBoxes with an image as the CheckBoxes appear grayed out and difficult to see. The GridView is linked to a SQL DataSource to display information only.
The problem I am having is displaying the image for unchecked boxes where the data (PET) in the SQL table is set to 'false'. The code displays the checkbox image fine when the bit is set to 'true', but no image appears in the GridView rows where the bit is 'false'.

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
The above error occurs with gridview control , when used with template field columns with item template / and edit templates etc.
updating a row within gridview, at the time of loadiong it loads perfectly fined, but when tried to modify an existing row within gridview control, then it produces the error. Make sure the grid view control has to be a child control which manages the child table info with in a master form. to reproduce the above problem the grid view must be loading the child records info of a master within the masterform, meaning both master data and gridview data all to be managed in one single form.
I had to replace gridview control with datagrid and then it worked perfectly fine. I wasted almost 4 days of my time., there is no way we could figure out the problem. here is the full info of the problem.

I am trying to replace carriage returns from a column in a database (MS access) with the br tag.
This could be easily done in classic ASP with <% = replace(recordsetField , Chr(13),"<br>") %>
Not sure how I would do it with .net (c#)

I have this scenario where i want to select multiple customers at a time and add them to a group/role. to do this i thought of using a gridView and listed them all with sqlDatasource and enabled 'selection' for gridview. but by default grid view is allowing only one selection at a time. so is there a way i can insert a new column of check boxes and some how read the gridview to know which checkboxes are selected? if you know a better approach than a gridview or check box please suggest me. i am not very familiar with asp.net so

I am working on creating a stored procedure that will output a pivot table. In the pivot table will be either the string NULL or a number. How can I reformat this in ASP.NET so the NULL value becomes a blank cell in the gridview and the number (whatever it is) becomes an 'X' ?

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!
