This is my first post as a newbie to asp.net.
I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.
What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.
So far my edit page has a datagrid with the following code:

I have 2 grids gvParent & gvChild I would like to filter gvChild when a row is selected in gvParent the linking fields are contractNo
I added a column for selecting:
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Select"
OnClick="LinkButton1_Click" Text="Select"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.

Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.
[URL]
I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.

I have a small gridview containing two columns: "modeluserid" and "modelid". It fills out nice.
[Code]....
Now, I want that when the user selects a row, he is automatically getting redirected to another page.
For example: (/Evaluationform.aspx?modeluserid=1&userid=1)I've used this code in the c# behind:
[Code]....
The url is generated on each click and the userid variable in the url is correct.
The only problem is that the modeluserid always stays the same for each url? ("1", first value in the table). Does someone know what I am doing wrong with the modeluserid variable?
Is it also possible that the user has to "select" the row instead of an "onclick" on the entire row?

Is it possible to save selected items in a gridview for future purposes?
let say i have a gridview, from all items selected in the gridview I want to give the user the possibilty to save the selected Items,.
in this case the items is data of persons, name adres, email etc. If the data is saved (for instance in a textfile) it should be reusable the next time. so a user can choose again a selection frmo the gridview or can load the earlier saved list.

I have a gridview on a web page as shown below
[Code]....
On checking the checkbox, the user will actually be selecting the products that he/she wants. The selected products will be stored in an arraylist by using a foreach loop through the gridview. The arraylist will then be saved to a session before being redirected to another page. (a button will be clicked after the selection of products to proceeed to another page)
On the redirected page, a bar graph needs to be generated based on the products selected previously and also the product sales (this is retrieved from the database).
How can I generate this bar graph without having to code the whole graph out?

I have a datagridview control that I'm using to display cache data to the end used on a web form. The issue that I'm having is that every time I re-run the application, and the cache data is re-generated... it loads duplicate data that's being displayed to the end user. I can't seem to figure out how to keep this from happening.
What I would like to have happen is that only unique data rows be returned and cached for the end user. Unless there are new data rows on the database that needs to be included in the cache data results...the previous data results should not be duplicated. I've tried to change a few properties on the datagridview control, but nothing seem to keep this from happening.

How do you save a radio button selection to a DB (within the .aspx page)? I have 5 sets of "yes/no" radio buttons (1 for yes/ 1 for no). Do I just add each radio button as a field into the DB and if its not selected, leave it NULL (or whatever the default value is)... this does seem very efficient.
