View 1 RepliesI have 2 views in sql server and I create a dataset with those 2 views as datatables. Now I need to create a datatable and programmatically fill it with the other 2 datatables. Take the 2 datatable and create a third one in the dataset not create a third view in sql server.
View 2 RepliesI have a gridview on a page and based on the row selected I need to fill out a form view (dynamic data enabled) from a linqdatasource. On gridview_sleectedindexchanged I create the linqdatasource and set it as the datasource for the formview. It displays nicely but clicking update returns a "Could not determine a MetaTable" error for the datasource mapped.
THe goal is to create a single page that allows users to select a row then get the appropriate data, create an updateable formview so further edits can be done. Do not want to scaffold.
let's say we have datatable with "<a>12</a>" as rows.when i try to bind it to gridview programmatically
I'm not getting href links like 12 But just a strings like "<a>12</a>"
Code:
Dim datatable as new DataTable
datatable.Columns.Add("No")
dim datarow1 ad DataRow = datatable.newrow()
datarow1(0) = "<a>12</a>"
datatable.rows.add(datarow1)
gridview1.DataSource = datatable
gridview1.DataBind()
I have a dropDownlist in a Formview Edit and Insert Template that is Bound to a Field, It is for a credit card expiration date, so I want to programatically populate it so it will automatically show the next 8 years from this year. Works fine!
Except When I add it to the Formview, and click on edit it gives me an error basically saying my record does not match the list item data, but it should since it shows the year just fine. So I am figuring that it is not binding the ListItems to the dropdownlist.
I have tried every event I could try and I always get the same error. I have tried the ModeChanged, DataBound, DataBiding, PreRender, Load on both the Formview and the DropDownList, but no go. How do I do this?

This works fin on a DropDownList that is not in a FormView, so I know its not the Code. and the record I am updating is 2010, so the record is not out of range
Using C#, Visual Studio 2010
I have 8 drop downlists created in .aspx page.
I try to programmatically fill the 8 using a single datatable. Each dropdownlist has its own column in the datatable and is supposed to display only the column that corresponds to it. It does display the column it is supposed to however it also displays a number of empty slots equal to all the other columns combined.Here is the code can someone tell me why I get the empty slots?

For a large fillin form I use the asp.net FormView for the magic databinding to my model. In this model I've a property called Rides (shown below), which exposes a list, which I obviously not want to be replaced entirely. So I made it readonly.
However, this way I can't use the databinding features anymore. Is there a common solution for this problem?

My DataTable is programatically generated, and contains objects of type JobInstance in the cells.
[Code]....
When I bind this DataTable to an ASP GridView, it only displays the first column. But if I remove the "typeof(Job)" when creating the column (the line with // !!!), the GridView displays all the columns by showing the result of JobInstance.ToString() in the cells. However, I have no access to the underlying JobInstance object, only the string values that are being displayed.
I need access to the JobInstance object when displaying the GridView (for example in the OnRowDataBound), because I want to access the fields inside JobInstance for each cell to determine formatting options, and add other links in each cell.
I have a data table, in one of the column, I will have this data, I will bind the data table to a grid view. I was hoping that this column change to a hyperlink. But, it was display the entire text.
<A HREF="page_url">Remark(s)</A>
When I view the page source code, I saw this:
<A HREF="page_url;Remark(s)</A>
How to correct this?
