I'm using a book to create a shopping site and need to change the following code so that the current dropdown list, of colour options, is replaced by just read only text. I'm a novice and despite best efforts I can't fathom it out. If anyone can change the code for me I would be extremely grateful.
The code below is the code-behind page for a Product List page where I want each product displayed to also display its colour options as just text (I don't need the shopper to select a colour choice until they click through to the detail page)

I've been trying to figure this one out for hours now. I'm trying to figure out why IE8 insists on displaying my gridview differently than IE7 and other browsers. First of all, width is set to 100%. In IE7, the gridview uses up the entire space of the container it's in (like it should). In IE8, the gridview only takes up the space that is required by its content

View 4 RepliesI have data display in a gridview base on a dropdownlist. Basically, base on the downlist selection my gridview will be populated with the corresponding data. I have addresses and emails in the list. Where I am stuck and not sure how to do is export the emails to outlook for a mailmerge. For example, when the user clicks on button to send the emails in Outlook. The emails should be the ones that are display in the gridview. For the MS Word is to export the address to populate the the labels so the user can print out labels. Another button to send the address for the labels
View 7 RepliesI need to create a gridview to show in each row, some columns from the SQL Database, and in other columns I want to have text fields, buttons and DropDownLists!
This GridView is to display the users of the web application.
First columns are name, email, and other stuff that can be easly queried to the SQL database.
Then, I need to have a column with one text field, and some buttons, in the text field the AdminUser should be able to insert some text and then click in a button to change the email/pass from the user represented in that line.
The other field I need, is a DropDownList that shows by default the Role of the user of the row, but we can choose another role and apply it, with a button in the same cell!
If I create a code-Behind query and populate the GridView, I don't know how to insert textbox's, button's, DropDownList's
If I create the GridView with the wizard, I can had TemplateFields, but I don't know how to associate the query with the BoundFiels where should be the name/email of the users.
Other problem, is that, even If I get to construct my GridView with sucess, How can I reference the row? So I can apply the changes?
I am trying to apply the same logic I applied to a FormView. Here is what I do: I have a DropDownListBox as one of my FormView fields and when I choose a specific option the fields inside my FormView are enabled/disabled according to the options chosen.

I have a gridview with dropdown boxes. As soon as the complete gridview is databound, I want to loop through ALL the rows and set the values of the dropdown boxe in a row based on the value of another column in the same row. The gridview is databound, all data shows up. The condition "If ddl.Items(j).Value = searchstring Then" evaluates as true, but somehow the selected item in the dropdownbox is NOT changed and remains "<ignore>"

I have a bound dropdown list populated with a table of names through a select, and databinding. it shoots selectedindexchanged that (through a postback) updates a certain gridview.What happens is, since it runs from changing the index, the one that always comes selected (alexander) can only me chosen if you choose another one, then choose alexander. poor alexander.What I want is to put a blanc option at the beginning (default) and (if possible) a option as second.I can't add this option manually, since the binding wipes whatever was in the dropdown list and puts the content of the datasource.

I am trying to have a dropdown in a gridview. I dropdown will hold data from a column in a sql database table. So far, i have this code but when I test the page, the gridview is just pulling the data from the column and displaying it without the dropdown feature. In the code below, "label" is a field in the databaseI have tried to use the info in this walkthrough, but even this does not display the DropDown for me...so I might be doing something wrong.ttp://msdn.microsoft.com/en-us/library/ms178294(VS.80).aspx
View 3 RepliesI have a GridView, with a DropDownList as one of the Columns. I can get the SelectedIndexChanged method to trigger - but I cannot figure out how to get other Data regarding which row this triggered on i.e. if I could get the value in the ID column (DocID below), that would be great. My code is a bit too long, so I am just posting snippets. In the *.aspx file I have:

In the *.aspx.cs File:
[Code]....
I am wondering if I can get the DocID from within StatusDropDownList_SelectedIndexChanged - so that I can make appropriate changes to the Database. For e.g. in the RowDataBound event, which I had a GridViewRowEventArgs e, I could easily do e.Row.DataItem - to get the DataItem, I am wondering if I get/do something similar in the SelectedIndexChanged method. (I would prefer this be not the GridView Row Index i.e. I would prefer the DataItem if possible.)

I have 2 drop downlists 1 gets the User hits my sql database and pulls back all my users in the database. I have post back on. The second drop down brings back all the account numbers for the user that is selected in the first drop downlist I have that post back on also.
My gridview then uses those 2 dropdownlists to populate for that user and that account number selected.
Now for the problem.
User Albert is in the drop down when page is loaded because its sorts by name the first account number for albert is in the 2nd drop down and the gridview works on page load for albert and account number 1 i can select account number 2 and the gridview changes.
I then switch user to Bill and it populates the 2nd drop down with Bill's account numbers however my gridview at this point is still showing alberts account information. I have to take drop down 2 and select another account say account 2 then my gridview displays bill's account 2 information i can then switch back to account 1 for bill and see that account information.
What do I need to do so that my gridview will populate when the first dropdown is changed to match the 2 new values?
Here is my code

I have a gridview that has a dropdown on a template on the row. The user is wanting to change the value and update the record automatically. I know that when the value changes, I need to have the OnChange to trigger. I am not sure how to get the row so I can get the record ID so I can create a SQL statement to update this field.
Should I be using something other than the gridview?
