Is it right way to get the selected values in DropDownList
Code:
cmbType.SelectedValue = reader.Item("HeadName")
or Please suggest the right way
I m getting the below error on this line
'cmbType' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I am using SelectedIndexChanged in the DropDowList and it works fine and populates a GridView based upon a site selection.
Is there there a way I can reset the SelectedIndexChanged so if user wants to refresh the GridView they would open the drop down list and click on the same selection again?
I am populating a DropDownList from a text file (class requirement).
The file is read in the Page_Load method and the DropDownList is populated then.
When I press the Submit button, throughout the process of the code it is supposed to get the SelectedIndex and use it to grab a value out of a List(Of ).
The thing is, nothing is ever passed through. I even setup an alert box and it passes right over the alert box and never even triggers it, but gives me an Index out of range error when it moves to the line right after the Alert.

I am having a problem with disabling DropDownList based on the chice of 1st DropDownList, there is no post back occuring, and it is a template based web app here is the current code:
<script type="text/javascript">
$(function() { var dropDownList1 = $('#<%= ddlUserType.ClientID %>');
var dropDownList2 = $('#<%= ddlMember.ClientID %>'); dropDownList1.change(function(e) {
if ( jQuery("#ddlUserType").val() != "ETOC") dropDownList2.removeAttr('disabled'); e.preventDefault();
else
dropDownList2.removeAttr('enabled'); e.preventDefault(); }
} );
</script>
what is happening now is page is blank and if I remove the above code everything shows, where I am going wrong. here is the plain and final javascript code which worked:
<script language="javascript">
function CheckDropDownState(lstbox)
{
if (lstbox.selectedIndex == 3) { document.forms[0].ddlMember.disabled = 1; }
else { document.forms[0].ddlMember.disabled = 0; }
}
</script>
and thew .aspx code: <asp:dropdownlist id="ddlUserType" runat="server" onclick="CheckDropDownState(this);"></asp:dropdownlist>
protected void DDLzone1_SelectedIndexChanged(object sender, EventArgs e)
{
BindDistrict();
}
[Code]......

View 1 RepliesI have two pages manager and user both have drop downs as
Week, Months and Years.
User have to enter some data week wise for each months and Manager have to approve that.
To Approve manager select months and week from dropdown on his own page and then navigate to User page.
How does I should bind the drop down so that if manager select 1st week from it's page and goes to view link of user then in drop down of user selected value shold be the same as selected by Manager on his own page.
I have a dropdownlist on my page with dates such as 1/1/2013, 2/1/2013, etc.
Then there is a second ddl.
If the date in ddl #1 is before 1/10/2013 I want to enable ddl #2.
If the date in ddl #1 is on or after 1/10/2013 I want to either disable ddl #2 or hide it (whichever's easier).
Disabling ddl #2 based on the selected date is a new requirement so I am enhancing the existing code. Obviously I want to do this without a postback, but I don't know what is the best way. I am trying to understand what an AsyncPostBackTrigger is because this is the existing code:
Code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:dropdownlist id="EffectiveDateDropDown" runat="server"></asp:dropdownlist>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="QuoteType"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
It wants to do something when the selected index is changed? This exists in the code-behind, but I set a breakpoint and never hit it:
Code:
protected void QuoteType_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
}
catch (Exception err)
{
this.PublishError(err);
}
}
I am binding months to a list 0-13 items default selection is 0 months duration, and years 0-8 items and 0 years is the default selection.As I know there are always going to be 12 months in a year, I could use selectedvalue or selectedindex without any perceived problem. Is there a reason why I should not use either/or of the two properties to select a list item?
View 2 RepliesI am trying to make a simple dropdownlist.Based off what is selected as the dropdownlist, I want it to open a new webpage.
For example:
Here is the dropdownlist - If they select team1, I want it to open up webpage /team1.aspx If it's team2, team2.aspx and so on.
<form id="form1" runat="server">
I thought this would be pretty simple, and in fact it's working on another dropdownlist on the same View, so I'm hoping I missed something very small that is easy to fix. Here's my code:
[Code]....
When I step through the code, the 'Active' option's 'Selected' property is being set to true. That's expected. But when the View renders, it's not selected and a look at the page source shows that the selected property isn't set. What is the problem here, and what's the solution?
how i handle this problem..Its in hidden filed.
