Dropdownlist In .net C# / SelectedItem.Text == "Reg" STA And STM Are Not Present?
Nov 16, 2010
I have two dropdownlist's.DropDownList2(not bound to a datasource) and DropDownList3(bound to a datasource)
On change on input in one dropdownlist some content in the other Dropdownlist should change. For that i had used the logic as.
Autopostback is enabled for both this controls.
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
if (DropDownList2.SelectedItem.Text == "Stamp")[code]....
Now the problem is when i select DropDownList2.SelectedItem.Text == "Reg" STA and STM are not present. I want STA and STM values back in the dropdownlist on selection of 'Reg'.
When i first load my page and select 'Reg' all the values in DropDownList3(including 'STA' and 'STM') are present and than when i select 'Stamp' the values 'STA' and 'STM' are lost(as shown in the code). Now again when i select 'Reg' this values are not there, i want this values to be present again. What do i have to do?? Do i have to bind it again to database?
Is there any other logic for it to be used in a different way ?

I have a dropdownlist is set to '--Select Item--' when the form is loaded first time. I don't see the Selected Item getting selected after I submit the form. It is set to '--Selected Item--' again.
<%= Html.DropDownList("lstDetails", new SelectList((IEnumerable)ViewData["DetailList"], "ID", "Details"), "--Select Item--")%>

I have a dropdownlist in a Usercontrol defined in a table as:
<asp:DropDownList
runat="server"
id="lstDIDFCM"
Width="135px"
AutoPostBack="true"
></asp:DropDownList>
i have the AutoEventWireup="True"; I have a breakpoint in the code behind on the SelectedIndexChange event.
The event does fire but the index is not changing. No matter what item in the list I select, the SelectedIndex always = 0. The list is bound to a dataset and the DataTextField and DataValueField are both set to the same value. Why is the index and SelectedValue not updating?

First post here, I usually try not posting until I am completely lost. I have a webform that gets a dynamic dropdownlist added to a placeholder in a method during pageload. During a submit of the page, I want to be able to get the selectedItem in the DropDownList that was also added dynamically from a DB. I know the ID of the DropDownList, and I know the Value of all the ListItems. Although when I am trying to use FindConrol(ID), and assign it to a DropDownList, the Control comes back Null and I get an error saying "Object Reference not set to and Instance of an Object", I believe because its not finding the control.
[Code]....
Can anyone show me how to use this to get access to the properties of the dynamic DropDownList properties, especially the ListItems within.

I don't know how to go about this. I have web form with two dropdown lists. one named Recruiter and the other Account manager. I have two two SQL tables named Perm_Commision_Lookup & UserList. The Perm_Commision_Lookup table does not contain recruiter's email, so I decided to Inner Join it with UserList table which contain recruiter emails. The LookupValue column from the Perm_Commision_Lookup table is what's displayed to the end user and the pk_LookupID column is the one that's inserted into the database. What I want to achieve is this: When a user select let's say "John Doe" from the Recruiter dropdown list, I want to send out an email to John Doe and at the same time insert the selected value (pk_LookupID) into the database. I set the DataTextField="LookupValue" and DataValueField="pk_LookupID but how to get the User_Email is another problem. Below is my SQL select...
SELECT Perm_Commision_Lookup.pk_LookupID, Perm_Commision_Lookup.LookupValue, UserList.User_Email FROM Perm_Commision_Lookup INNER JOIN UserList ON Perm_Commision_Lookup.LookupUserName = UserList.GM_Username

I am handling the row databound event. I need to bind a dropdownlist which is present only in the EditItemTemplate.
So it is throwing:
DropDownList ddlAccountingPeriod = e.Row.FindControl("ddlAccountingPeriod") as DropDownList;
UIControlHelper.BindApprovalPeriod(ddlAccountingPeriod);
this throws a null exception as the dropdown is not present in the ItemTemplate.
Is there a way to check whether it is itemtemplate or edititemtemplate.

This system is - AUTOMATIC - and it is restricted
Look the symbols before and after the word AUTOMATIC. When I try to write this on a dynamically generated html page using the code bellow, i got this on the screen:
This system is â€" AUTOMATIC â€" and it is restricted
Code used to print the SQL Field:

The - symbol is not a minus symbol, but is a Word minus (-) symbol...

Can any one let me know "How to validate the length of the text present in the textboxes of a Gridview using javascript".
For Example: In a page I am displaying a Gridview with textboxes inside it and a button on the page. The user need to input some text in the textboxes of the gridview and click on "Submit" button. When the user clicks on Submit Button, we need to validate the length of the text present in the textboxes of the gridview. If the length of the text inside the textbox of the gridview is less than 10 , we need to throw an error message. In the same way we need to do validation for each and every textbox inside the gridview.

I give up. After many hours of scouring the internet, cannot find a simple example of binding a simple object to a ListView and figure out which one is selected in the SelectedIndexChanged event.
Many people talk about the SelectedItem and SelectedItems properties; which somehow, according to intellesense, do not even exist on my ListView. I must have a "special .Net build" :)
If I have a collection of "Books" bound to a ListView. How do I get the "selected book" in the SelectedIndexChanged event? (Multiselect = false)
I would think it's something like:
Book MyBook = (Book)ListView1.SelectedItem
I'd even settle for
Book MyBook = (Book)ListView1.SelectedItems[0]
No such luck. My very special ListView does not seem to have either property.

I've been pulling my hair out over this one... I've searched on the net and even in the forums, but can't seem to come up with an answer for a simple question.I tried the following code inside my html to get the selected value that comes from our database into the grid and it doesn't work. I am positive that a value exists for the itemType. It is 1. Instead of Checked, I tried SelectedItem and SelectedIndex. Neither of those worked.
<code>
Checked='<%# DataBinder.Eval(Container.DataItem, "itemType")%>'
</code>
I erased the above code from my grid and inside the ItemDataBound event, I placed the following code, but don't know what other code I should place next after it. I know the value inside "itemType" is 1 by debugging it.
<code>
RadioButtonList itmtype = e.Item.FindControl("rblItemType") as RadioButtonList;
</code>
How can I simply find the selecteditem in the list coming back from the database inside the itemdatabound event?

I am using VB.NET and I can't compare the radio button lists selectedItem.Value to a string, it doesn't work...here is the code: (I have also tried selectedValue it does not work either)
Response.Write("RB1: " + rblOne.SelectedItem.Value + " FML FML FML<br/>")
If rblOne.SelectedItem.Value = "No" Then
Response.Write("Hey there!<BR/>")
pnlR1.Visible = True
If NumberOfAnswers = 7 Then
Score = Score - 10
ElseIf NumberOfAnswers = 6 Then
Score = Score - 15
Else
Score = Score - 20
End If
Response.Write("Score: " + Score.ToString)
End If
Response.End()
If rblOne.SelectedItem.Value = "No" Then is not working, notice the debug statements in there, here is the output: Why won't it evaluate that rblOne.SelectedItem.Value = "No" !?!?!? I tried rblOne.SelectedValue, that doesn't work, AND I added .ToString to both
