Forms Data Controls :: DropDownList.SelectedIndexChanged Not Working

<asp:SessionParameter

</SelectParameters>
</asp:SqlDataSource>
<asp:DropDownList

AppendDataBoundItems="True"
onselectedindexchanged="ddlPrescriptionCode_SelectedIndexChanged"

</asp:DropDownList>
<asp:SqlDataSource
ID="PrescriptionCodeDataSource"
runat="server"
ConnectionString="<%$ ConnectionStrings:SystemConnectionString %>"
SelectCommand="SELECT [PrescriptionCodeID], [CodeDescription] FROM [PrescriptionCode] WHERE (([Archived] = @Archived)

<SelectParameters>
<asp:Parameter

/>
<asp:ControlParameter
ControlID="ddlPrescriptionCodeGroup"
Name="PrescriptionCodeGroupID"
PropertyName="SelectedValue"
Type="Int32"
/>
</SelectParameters>
</asp:SqlDataSource>

When I select from the first dropdown I want to populate the second. However, this is not happening. The postback is happening, but the SelectedIndexChanged handler isn't being called (I have a breakpoint which isn't being hit). The user controls are created dynamically and put into a PlaceHolder which itself is within an AJAX Updatepanel, with ChildrenAsTriggers set to true.

Aug 4, 2010

I ask for a date, on OnTextChanged event i bind data with a SqlDataSource to a dropdownlist and also bind data to a repeater passing the dropdownlist SelectedIndex (i use SqlDataSource too and ControlParameter to link the dropdownlist and the repeater) On my repeater during the ItemDataBound event i create dynamic dropdownlist controls, my code is :

Everything works fine, datas are bound and SelectedIndexes are restore on every postback.

The probem occurs when user change different dropdownlists, if he choose to change the 1st dropdownlist the event is fire (normal), after if he modifies another dropdownlist the event is fire twice, if he modifies a 3rd time the event is fire 3 time etc...

Forms Data Controls :: Fire SelectedIndexChanged Event Of DropDownList When SelectedValue Is Coming From Database Table?

Jun 28, 2010

I have a form which has some dropdownlists (ListItems "Yes" "No"). I use my form to Enter data & submit to database and use same form to Edit aswell. Like I redirect to this form from another page with a QueryString. If there is a QueryString then SELECT * FROM Table WHERE ID = QueryString's value & fill all the controls in the form like

[URL]

I have certain things to do when DropDownList.SelectedValue = "Yes" so I can use SelectedIndexChanged event handler & AutoPostBack="true" when submitting form for the first time. Now when I edit the information(Data filled from table as stated above). How can i automatically fire all events like DropDownlist SelectedIndexChanged in the page_Load iteslef so that all the things that are supposed to be done when DropDownList.SelectedValue = "Yes". I'm posting my test code for reference to explain what I'm trying to do. This is just the Idea. I have something else to deal with if i can get this stright. I need to dynamically add controls based on the values of DropDownList. please suggest some thing guys.

Forms Data Controls :: Update Databse With DropDownList In GridView, SelectedIndexChanged?

Nov 20, 2010

I am new to asp.net (I may use some incorrect termology while I explain my issue...) and need some help with DropDownList in Gridview. Currently I have a GridView set up with three Columns bound to a database: Column1 - some kinda of index, Column2 - string, Column3 - DropDownList(called Active). So far when I build the page, all the columns show up and the DropDownList appears and the values are bound correctly. I want to change a value in the DropDownList and automatically update that value in my database.

I have set AutoPostBack = true and I made a DataObject (called UpdateActive) to update the database (it takes 2 inputs, the Column1 index and Column3 DropDownList value).However, I don't know how to find the row that I am changing, is there a way to figure out what row it is (like finding the Column 1 index?). Also, I don't want to have to click a button to update the data.

Forms Data Controls :: Disable Autopostback Of Checkbox Inside Of GridView During SelectedIndexChanged Of ListView

Sep 8, 2010

I have a checkbox placed inside a gridview:

<GridView><asp:TemplateField HeaderText="Driver"> <ItemTemplate> <asp:CheckBox ID="CheckBoxDriver" AutoPostBack="true" OnCheckedChanged="GridView_Persons_SelectedIndexChanged" ValidationGroup='<%# Eval("ID") + "-" +((GridViewRow)Container).RowIndex %>' CssClass="CXDriver" runat="server" Checked='false' /> </ItemTemplate> </GridView>

For example: A listViewItem 1 has 3 drivers are checked, A listViewItem 2 has 2 drivers are checked.

Therefore, if changing the selectedIndex of the list, the checkbox indexChanged event will be fired.

How could I disable the autopostback of the checkbox during the listview item changed.

Forms Data Controls :: LinkButton (ADD) In Footer Not Working In GridView?

Jul 29, 2010

I utilized the "Enhancing the GridView (Inserting a New Record from the GridViews Footer)" tutorial as an example to add a new record to the Access Database through the footer. Put a break at the RowCommand, but that never happens and the data that I put into the cells in the footer just sit there when I click the ADD link. I have included the portion of the code in CourseBuildDetail.apsx that deals with the TAB that contains the GridView, along with ObjectDataSource and the code that should be triggered when the Add link is click - CourseBuildDetail.apsx.cs. So - what am I missing - example works great.
