I am having trouble using the values that were selected from the dropdown list. How would you reccommend passing the selected values from the view?Ideally, we want to use the selected dropdown values to determine a query.
View 1 RepliesI have a list of servers in the first dropdown. I want to get list of all databases in the second dropdown depending on the server selected in the first dropdown.
For this I need to query each server while selecting the server.
Check this code. Here I populated Dropdown with volumenames from webconfig file. Here I am getting volumename from webconfig file and in page load event I want to show this volumename selected.

I have a dropdown list that will add new titles to my database, however I would like to add a textbox that will allow the user to type in a new title if there is nothing in the dropdown that makes any sense for what they are trying to add.
I have the dropdown dynamically getting titles from the database. Unfortunately, this means that the first value in the dropdown list is not a default that says "Select an option." I don't know how to get the dropdown to have the first option listed as "Select" when the values are being pulled from the database. I can't add Select an option to the database so how would this even work?
What can I add to my codebehind that will allow the textbox to insert into the database if the dropdown list is not inserting anything? Right now I don't have any codebehind for the textbox but I do have the dropdown list inserting the correct information.
<li class="alternatingItem">

I have an asp.net dropdown like this
<asp:DropDownList width="95%" ID="RessourceComposantes" runat="server"
DataSourceID="Composantes"
DataTextField="Description" DataValueField="ComposanteID">
</asp:DropDownList>
[code]....
Is it normal that when I do dd_ressource_composante.selectedvalue on the server side I have no value. It's always "". the source looks like this :
<select name="ctl00$Tab$dd_ressource_composante" id="ctl00_Tab_dd_ressource_composante" style="width:95%;">
<option value="1">Composante</option>
<option value="3">DGAG</option>

I just tried to fill my dropdown in vb.net and I have the same result. The dropdown is full but when I do a postback I have no selected value Actually on the server side when I put a breakpoint on the dropdown, the item count is 0. I don't understand why... It's like the 8th dropdown list in this project and everything is the same but this one doesn't work.
I don't do any binding on the page load. it's all in the aspx file well it works ONLY when I add autopostback="true" SelectedIndexChanged="dd_ressource_composante_SelectedIndexChanged" for the dropdown.And theres no code in dd_ressource_composante_SelectedIndexChanged It's vb.net for the server side?
doing dropdown list selected index changed. I wan to select an item in dropdown list and display in textbox but I got more than 1 textboxes. Is the style sheet (.css) going to hard code by our own. how do I go about starting with it as I am a beginnner using visual studio.
View 1 RepliesI 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 have three dropdowns, which are all loaded in the same function. How do I grey out dropdown 2 & 3? I want them to activate if a certain choice is made on dropdown 1.
View 2 RepliesI have a comboBox that is populated with a dataset. The values are:
KG - Kilograms
LB - Pounds
and so on.
So when the user clicks the comboBox in the DropDown the user will see:
KG - Kilograms
LB - Pounds
and so on.
[Code]...
I have a combo box that has a drop down list with long values in the drop down
Ex:
LB - Pounds
GR - Grams
When the user selects on of the values I want to just show the Abreviaqtions and not the descriptions. So when the drop down is shown it shows
LB - Pounds
GR - Grams
When the user selects "GR - Grams" from the drop down list "GR" is the only this shown in the combobox. I've tried TextChange,SelectedIndexChange and SelectedValueChange but I can't get them to work.
VB.NET Winforms Application... When a user starts typing in the search box of the application it automatically populates the name list dropdown box with the valid results and sets the droppeddown value to true... Everything is working fine except the fact that the user is forced to select a value from the name list or press the esc key because without doing so the mouse cursor just disappears and you have to move the mouse all the way outside the application for it to come back and it will only do so while outside the applicaiton.. Below is the code that I am using for this and it should be noted that I am using the droppeddown value else where in the application and none of those instances have an issue its only this one..
Private Sub u_lastName_Box_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles u_lastName_Box.TextChanged

View 1 RepliesUsing VB.net 2010 i am trying to figure out if an item was selected or not. Reason being is that if the user clicks on an item and pushes a button then everything works just fine. However, if the user selects an item and then clicks on a blank spot on the bottom of the listview and then clicks the button then it crashes.
My code is this:
If (lstMaster.SelectedItems(0).SubItems(1).Text) Is Nothing Then
MsgBox("test")
End If
im trying to determine if there is an item selected on the listview..
i have a listview that displays customers name with a .tag that holds there ID.
how do you tell if the tag is 0 or empty before executing code?

the code i want to execute if there is a tag (or atleast a listitem is selected) is down here.

I want to add a context menu to a datagrid in VB2008 and I need to find out which menu item the user selected.
I don't want to use the ContextMenuStrip that's available in the toolbox since it doesn't allow for dynamic placement depending on what row is active in the grid (I haven't found a Top and Left property in the ContextMenuStrip)
Here's what I've got so far, I'm aware of the fact that the MsgBox uses a non-existing property, it is meant to show my intention.
Given the available properties in the ContextMenu object, I would think that there would be something like a SelectedItemCaption property but a search of the object tree yields no results.
dim grdContextMenu as ContextMenu
grdContextMenu = New ContextMenu
grdContextMenu.MenuItems.Add("Insert")

I'm a student and I have a small project to create for my VB class. For the personal touch, I tried using a ListView to manage a SQL database (on a remote web server).What I need to do right now is determine how many items are selected (if more than one, enable delete and edit buttons, if more than one, disable edit button). I searched a lot for that, but didn't find anything working with me.Do you know a simple way I could get the number of items that are selected in my ListView?

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.
I am making a app that reads options of a ini
dim config as new iniconfigsource("patch.ini")
dim test as string = config.configs("news").getstring("test")
Then I made a dropdown with options
I want my script to compare the values of the dropdown with the string readed from the ini
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
dropdown1.selectedindex = 0
I am trying to write a LINQ query which will return true if there are multiple objects which have a property with the same value.
Here is what I have come up with so far:
Formatters.Where(Function(f As DataModel.Formatter) _
Formatters.Select(Function(f2 As DataModel.Formatter) f2.Name.ToLower()).Contains(f.Name.ToLower())).Count > 1
However the above always returns true as long as their are more then 1 elements in the list?

View 3 RepliesHow 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.
VBE 2010, and I'm hitting an AccessDB
I want to have a drop down menu with the values:
Year 7
Year 8
Year 9
And I want to display different tables for each the values selected in the drop down menu. For example, when the "Year 7" value is selected in the drop down menu, a table is displayed for that year.
I am using VB .Net for this, so I don't have access to var or this would be a simple matter.Right now my query is as follows
[code]...
So I used this query in LinqPad to help me determine what the object would look like. I got back a IOrderQueryable(Of RSError) which then contained a IGrouping(Of String, RSError) for each grouped collection of objects returned by the query.However I ended up with the current object type of errors as IOrderedQueryable(Of IGrouping(Of String, RSError)) because of the cast error I am getting in VS.

I am using a webbrowser control, which is used for both internet and folder exploring. How can I determine when viewing files on the local directory, which file is selected?
I ran across something in my searches saying there was a property under the webbrowser.document called SelectedItem. But this must not be in 2008.
