I have a gridview with a dropdown list that was created programmatcially. I want to have access to the selected value and to that row's Id. I have the dropdownlist created in *Gridview_RowDataBound* and I am able to use the text in the cell but my addHandler is never fired. Where do I give it the Add handler. I believe I can assign it the addhandler in RowCreated but how would I be able to set up the add handler if the button is created in rowdatabound?
[Code]...
It fits best in Rowdata bound because my dropdownlist items don't duplicate but I need to be able to use the addhandler I created.

I know the question is a little choppy and perhaps misleading,but I have a gridview with dropdownlists on the rows. I created an AddHandler and a Delegate for the SelectedIndexChanged and it gets to the sub. Here is the code for that:
AddHandler ddlmgr.SelectedIndexChanged, AddressOf ddlmgr_SelectedIndexChanged
Public Delegate Sub DropDownList_SelectedIndexChanged(ByVal sender As Object, ByVal e As DropDownList_SelectedIndexChanged)
Protected Sub ddlmgr_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
End Sub How can i get the row's Id if GridView_RowCommand is not called?

I've created a custom user control that has several properties. One specifies which database I want the control to access. I want to be able to present the user of the control a drop down from which he can select which database the control will interact with. How do I get the dropdown to work? I can get default values, but have yet to figure out how to get the selectable list.

I have been searching everywhere but I am unable to find a reference to what I need.I have a huge number of entries where each entry is composed of three long numbers:
a b c
1 2 40
2 1 40
1 8 12
3 9 13
8 1 12
ect.
in my algorithm I will find that I need to disregard values in column a which will then lead me to disregard values in column b. I initially thought that I may want to use three arrays and just change the disregarded value to a null value with each iteration. find function that would allow me to not have to loop through the entire array every time.This lead me to want to define the columns as lists where I could remove specific values from the list and reduce the size of the list with each iteration of the algorithm. The problem then is how do I say, listb.remove(8) and at the same time have the corresponding values for lista(1) and listc(12) removed?

I've never really used the Check List Box in the past, however, for the recent program I am developing, I am using this control rather than individual check boxes scattered across the form.Anyway, I want to be able to program through code which items get checked in this checked list box. Specifically, I have a variable that contains the text of each check box that I want checked.With a normal check box, I can simply say:
Dim strNames As String
strNames = "John Doe, Mark Johnson, Mike Brown, Cindy Smith"
If strNames.ToString.Contains("Mike Brown") Then[code]....

Suppose you have list 1 (ilist1) and list 2 (ilist2) both lists have 3 items.
At index 0 item1 which has text "-- Select --"
At index 1 item2 which has text "Yes"
At index 2 item3 which has text "No"
Both lists have identical items. I would like to know if it is possible to have the selection of list one be "Yes" and the selection of list two be "No" and vice versa using SelectedIndexChanged or something of the sort.
For example:
ilist1 = --Select--
ilist2 = --Select--

I have a custom control. I need to add a property, say, Comparison, to the control. The property should be set at design time using a dropdown. The Dropdown will have String values like '=','>','<' etc.
I tried using Enum values and working perfectly but I need to do some extra coding to convert the Enum values to the string I required. It would be great if I can get the values from the dropdown so that I can directly use the selcted value.

then uses it as selected value (the so called standard value) the one uc without clicking on the arrow if the none of the values match with the string value of the ini then it executes

How to set up a Chart using the new MS Chart control. I want to be able to populate the data via SQL because the user will be able to dynamically change the values via drop downs. The format of the data will be the same (Qty, Time Period) but the Focus of that data will change. I'm honestly not sure where to start, I can draw the chart but I have no idea how to populate it with data via code so it can be changed dynamically.

I would like my gridview to be filtered by the dropdown list I have. It is pulling specific information from the database, so when you choose a value from the dropdown list, it should search through all the records and find only records with the ddl value in them.
The code that I am using in the codebehind for the SelectedIndexChanged is not right though. I get an error message saying 'Value' is not a member of 'Integer'. This is on the line dsCompanyFilter.SelectParameters.Add
It probably has something to do with the gridview not tying to the dropdown list properly, but I am not sure how to fix that code.
