Forms Data Controls :: DataList / DataKey / EditCommand
Mar 15, 2011
I am using Microsoft's method for allowing editing/updating/deleting of a datalist:
<asp:DataList
runat="server"
DataKeyField="ChargeID"
ID="HistoryList"
DataSourceID="SqlDataSource1"
width="650px"
[code...]
I am using the ChargeID as the datakey for editing, etc., but I need to use the UserID to limit what gets populated into the datalist to begin with. I do have a session variable with the UserID, but how do I populate the list with data according to the UserID?

I have a DataList with controls in the Header that are used to filter the DataList. Everything works correctly until I try and edit the filtered DataList. Having set the EditItemIndex, I then need to read the values from the header filter controls to ensure the Bind returns the same collection of rows. I am calling a function that should return the Header DataListItem so I can get the filter values if set. The problem is the DataList Item collection does not seem to have the HeaderItems in it.

I need to loop through all the gridviewrows, and call a function for every row using the datakey. How do I get the datakey of each row?
My code looks something like:
foreach(GridViewRow gvr in GridView1.Rows)
{
DoSomething(gvr.INSERT DATA KEY OF THIS ROW HERE);
}

I have the DataKey value, I want to use that to get the GridViewRow and retrieve information from various columns - I see lots on information on how to get the datakey from a gridview row, but not the reverse.

Does any one know how set the FormView PageIndex to a DataItem with a specified DataKey?
Like:
DataKey dataKeyVal = myGridView.SelectedDataKey.value
myFormView.PageIndex = FormView.DataItems.GetByDataKeyVal(DataKey dataKeyVal).Index
The FormView is bound to the same ObjectDataSource as the GridView and the FormView uses the autoPaging so I can't just use a separate DataSource for the FormView with just one parameter being the ID.
There must be a way to set the FormView PageIndex by a Datakey value.

Lets say for example that I have a book object that looks like this:
[Code]....
And a Page_Load method that bounds a GridView called "gvBooks" from a generic list of books:
[Code]....
Now as you can see, I want to have the BookId value that is part of the Dictionary as a DataKey of the gvBooks GridView.
That piece of code of curse returns an Exception:
"DataBinding: 'GridViewTest.Book' does not contain a property with the name 'BookId'."
My question is: Is it possible to have the BookId value as a DataKey of the GridView?

I'm relatively new to the VS environment. I'm using VS2010 Beta 2 with VB. I have a Gridview setup to pull a list of employees. Next to their name I have edit and delete icons. When I leave the icons as ButtonFields, they pass the DataKey value to my code behind perfectly. When I convert the ButtonFields to TemplateFields, they no longer pass the DataKey.

i have a gridview that has only one column but multiple rows that i converted into a template column.
I have a linkbutton in this column that when clicked should collect the rows primary data key (forumId) and then insert it into a querystring and redirect to the threads page.
How do i select a datakey in the code behind file for the selected row without using the Selectedindexchanged event handler?
<asp:TemplateField HeaderText="Title" SortExpression="Title">

I want to select a row in my GridView based on a known data key value at runtime.
In other words, I have a data key value, 2 for ex., and the primary key value of one of the rows in my GridView is 2. How can select that row? (Without having to go through each row to find which one matches my key, then setting the SelectedIndex.

I have wired an event to handle delete command for my GridView. But I cannot determine which the record's unique key, in my case stored in DOCIDNO field. All I get is a row index, such as 0, 1, 2 which obviously cannot be used to accurately delete a record from database.
<asp:GridView
ID="gridTimeOff"
runat="server"
HeaderStyle-CssClass="gridHead"
RowStyle-CssClass="gridRow"

I have a gridview with a DropDownList (contained in a TemplateField). I have set the OnSelectedIndexChanged event to a function called "ddlAgent_SelectedIndexChanged" This allows me to aquire when a user has changed the value for the dropdownlist. What I need to do is persist this newly selected value to the database for the gridview record. The problem I'm having is how to I get the datakeyNames value for that row? See code below!
TemplateField source
<asp:TemplateField HeaderText="Agent">
<ItemTemplate>
<asp:DropDownList ID="ddlAgent" runat="server" AutoPostBack="False" OnSelectedIndexChanged="ddlAgent_SelectedIndexChanged">
</asp:DropDownList>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
ddlAgent_SelectedIndexChanged
Protected Sub ddlAgent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim gvItems As DropDownList = CType(sender, DropDownList)
' Write the selected Agent ID to the Inquiry record.
'Dim ID As Integer = gvMaint.DataKeyNames(e.SelectedIndex).Value ' THIS FAILS BECAUSE
e.SelectedIndex is not part of System.EventArgs
End Sub

private DataControlRowType templateType;

I have a Gridview which is populated from an ObjectDataSource. Data Source has a control parameter hooked up to the SelectedDataKey value of the GridView. My Gridview has rows which may not have a DataKey. I am receiving an error when a GridView row without a DataKey is selected.

I am binding SQL data to a GridView. The GridView's DataKeyNames property is set to the SQL column called "utID"
I know that within the SQL results, some of the utID values are NULL. After databinding to the GridView, I need to enumerate through the GridViewRows an read the DataKey values. However, when I try this I get the following error:
No default member found for type 'DBNull'. I am using the code below.
What object types are stored within DataKeys (I thought it was just integers or strings)
How to handle a NULL datakey value to prevent this error occurring?
I don't want to use Try Catch because it's too much of a 'hack'
