Forms Data Controls :: Unable To Set The SelectedValue Of DropDownList

Jun 15, 2010

My page has a gridview, and the gridview has a TemplateField called "Acciones" (Actions). The column Acciones has a ImageButton with CommandName "Select" and CommandArgument "Tutor". Thus, the GridView has controlled event "SelectedIndexChanged". The idea is that in GV_SelectedIndexChanged, I must to set DropDownList's SelectedValue property. But, the value seted in this function don't affect the rendered dropdownlist. The debugger talk's that the value is correctly seted, but the visual result don't.

I'm using a FormView which has odsMain as the datasource. I am also using a dropdownlist which is being populated with objectdatasource odsddl.

I'd like to set the selectedvalue of the dropdownlist with the value contained in odsMain (the current record value for it). Is there any way this can be done?

Forms Data Controls :: Dynamically Set SelectedValue In DropDownList With SQLDataAdapter?

Mar 28, 2011

I have a form that's being databound with a SQLDataAdapter. I have a DropDownList with a SelectedValue='<%# Bind("FieldName")%>' on it. I was wondering if there was a way I could remove this field and set it dynamically in the codebehind and still have it insert the value of this field with the SQLDataAdapter. The reason for this is because the control I'm using doesn't have a separate InsertItemTemplate, only an EditItemTemplate which serves both purposes, and I need this to dropdownlist to only be databound on Insert.

Right now it's looking like I'll have to stop using the SQLDataAdapter and Update/Insert the data in the codebehind, but I wanted to see if there was something I was missing just-in-case.

Forms Data Controls :: Dropdownlist Selectedvalue Does Not Exist Error?

Mar 2, 2011

I have a drop down list inside a formview control's edititemtemplate and itemtemplate. The dropdown list is not bound to a data source. I am hard-coding the listitems for the drop down list. The formview is bound to a datasource. All I want to do is set the selectedvalue of the dropdown to what is in the record from the database. But I keep getting the error.

<asp:formview .....>
<edititemtemplate>
.... //some other controls like textboxes that are correctly bound and display the value from the datasource
<asp:dropdownlist ID=myddl runat=server cssclass=myclass selectedvalue='<%# eval("mychoice") %>'>
<asp:listitem value='0'>I dont know</asp:listitem>
<asp:listitem value='1'>Yes</asp:listitem>
<asp:listitem value='2'>No</asp:listitem>
</asp:dropdownlist
.....//rest of the edititem controls that display correctly.
</edititemtemplate>

Just for kicks, I added a textbox and set it's value to eval("mychoice") as well and it correctly prints 0,1 or 2. So, I know that there is no illegal value coming back from the datasource. It seems as something with the timing of events - when the listitems are getting bound to the ddl. The error I get is - "myddl has a selectedvalue which is invalid because it does not exist in the list of items".

Forms Data Controls :: Prepare Dropdownlist Selectedvalue To Be A ControlParameter Source For ObjectDataSource?

Apr 12, 2010

I have following in many controls:

<asp:ControlParameter Name="SvcCluster_Id" ControlID="frmConfigEdit$ddlCluster" PropertyName="SelectedValue" />

Everything was good before I bumped into the problem when declarative binding (SelectedValue='<# Bind("SvcCluster_Id") >') produced the error, because value has not been found in the list. So i moved binding to the code:

protected void frmConfigEdit_DataBound(Object sender, System.EventArgs e)
{
if (frmConfigEdit.CurrentMode == FormViewMode.Edit)
{
var svcCluster_id = DataBinder.Eval(frmConfigEdit.DataItem, "SvcCluster_id");
var ddlCluster = (DropDownList)frmConfigEdit.FindControl("ddlCluster");
if (svcCluster_id != null && ddlCluster.Items.FindByValue(svcCluster_id.ToString()) != null)
{
ddlCluster.SelectedValue = svcCluster_id.ToString();
}
}
}

But now seems like this happens later than ObjectDataSource tries to access frmConfigEdit$ddlCluster...

How to manage this?

I wouldn't like to move everything to the code (I mean creating Control parameters, etc)

p.s. Oops, actually it works ok for DataBound event! Sorry.

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 :: Dropdownlist In Edit Template, In Detailsview. Getting "SelectedValue Does Not Exist In List?

Jun 7, 2010

I have a standard gridview and detailsview. My detailsview has some fields which are templates, with dropdownlists. The user selects a record in the gridview, then can go down to the detailsview, select Edit, and change some values (using dropdownlists).I am getting the error, "DDL has a selectedvalue which is invalid because it does not exist...." when I click Edit in the detailsview.

I know the problem has something to do with the dropdownlists not being instantiated or bound until I enter Edit mode. Is that right? In what event should I databind my dropdownlists? I've tried several things but could not get it to work. Do I have to loop through all the rows of my details view looking for the dropdownlists, or can I access them directly from some event?

Setting SelectedValue For One DropDownList Also Updates The SelectedValue For Another DropDownLIst

Jul 21, 2010

I have a WebForms page that has two DropDownList controls on it that both contain a range of temperatures from 60-80 degrees, one for heating the other for cooling. They are declared in the .aspx as:

<asp:DropDownList ID="heating" runat="server" />
<asp:DropDownList ID="cooling" runat="server" />

The values for each list are populated in the code-behind using:

for(int i = 60; i <= 80; i++)
{
var listItem = new ListItem(i + " degrees", i.ToString());

heating.Items.Add(listItem);
cooling.Items.Add(listItem);
}

When I try to set the selected value for each DropDownList using the values in an object containing data loaded from the database using:heating.SelectedValue = myHome.avgHeatingTemp.ToString();
cooling.SelectedValue = myHome.avgCoolingTemp.ToString();

The SelectedValue for both lists is set first to the value in myHome.avgHeatingTemp, then to the value in myHome.avgCoolingTemp. Heres what the values are for each variable after each step of the process of setting the SelectedValues:

Initial State
heating.SelectedValue: 60
cooling.SelectedValue: 60 [code]....

Web Forms :: Setting SelectedValue In Dropdownlist

May 11, 2010

I have a ASP.Net webform with a DropDownList control. This Dropdown gets it's values from a states table in an ObjectDatasource. The Dropdown contains states spelled out.

If I try to set the drop down to:
DropDownStates.SelectdValue = "Ohio"

I get an error that the value does not exist in the dropdown even though it does exist. But if I pad the value with the correct number of spaces to the right, it works like so:
DropDownStates.SelectdValue = "Ohio "
or
DropDownStates.SelectdValue = "Michigan "

How can I either define the dropdown without trailing spaces in the value of the dropwdown or set the SelectedValue with adding trailing spaces?

Web Forms :: Dropdownlist SelectedValue Not Changing?

Aug 26, 2010

I have a quick question on my ddl. I have a search page that searches based on the ddl. Once the button is clicked. the result of the search shows on the gridview.Which all works well.Now the problem i am having is that. On my gridview i have a select button that brings out another ddl on an update panel based on the first ddl. When i do this... it goes back to the first record on the ddl and shows a wrong result.. Basically the new ddl is supposed to change on "selectedindexchanged" handler of that gridview which works fine but the selectedvalue is just going back to the first one.
