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.
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?
I have an ObjectDataSource with a number of parameters. These parameters are binded in my FormView EditItemTemplate and the ItemTemplate. My Stored Procedure column names in my ItemTemplate are different to the Bind properties used in the EditItemTemplate. This is obviously throwing an exception when I update a record.
Instead of using Bind("Columne Name") in my EditItemTemplate how do I use a ControlParameter to reference a TextBox in the EditItemTemplate?
I may be wrong but I'm trying to use the PropertyName=Controls but i do not know how to reference the Textbox in the EditItemTemplate.
I have a dropdownlist in DetailsView to which items are added programmatically during DataBound event. It is working fine in InsertItemTemplate, but in EditItemTemplate i am getting this error "'branchDDL' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value".
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 want to display selectedvalu on dropdonwlist i have a access table like this;1 Adana2 Ankaraits displaying the numbers of cities but i want to display name of the cities in my gridview how can i fix that ? im using theese codes for register page;
string baglan =DugunSitemiz.Properties.Settings.Default.baglan; OleDbConnection conn = new OleDbConnection(baglan); conn.Open();
I'm populating a dropdownlist in a formview with a different datasource from the formview's. I need to set the selected value according to the value in the formview's datasource but I'm having a hard time doing that.
Here's the code: <asp:FormView ID="FormView1" runat="server" DataKeyNames="ID" DataSourceID="SqlDataSource1"> <EditItemTemplate> [code]....
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.
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".
I am having Gridview ie : inside i have placeholder, So on Gridview_RowDataBound - according the Specific Condition getting from DB then - i am Creating the Dropdownlist dynamically here and assign Datasource. so up to this its ok.

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.
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?
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:
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]....
How do I set the selectparameter of Objectdatasource in usercontrol from dropdownlist in parent page?I tried the following but when I select a new value in the dropdownlist it does not change the data from the initial page load

I have a dropdownlist that pulls from a datasource. When a name is selected all information drops down to a formview. Once there 3 fields get populated from the dropdownlist and then there is 2 other fields that need user input. Once they hit submit, it should write to a different table in the same DB. I cannot get the fields to populate and write to the DB. Here is my code:
I'm trying to link 2 objectdatasource together using the Control Parameter Source.However, I'm stuck at the screenshot below. The Next button is disabled.
I am having a problem with using A Gridview SectedIndex or value in a sql ControlParameter. When I select the row it does what I need it to except it shows that there is no data.
but if I add Default Value of 1 the data shows up, but it needs to read from the Gridview.
[Code]....
I even added sqlDataSource.DataBind() in the SelectedIndexChanged Event to see if that would fix it but - No! I used it with a DropDown and it worked only when I use AutoPostBack = true of course.
i am a new user of asp.net and i am a learner so i just want to connect two dropdownlist to data souce and i want that the list item of second dropdown is changed according to change of selected item of first dropdown.
i have connect it to data source successfully it getting chaged items but it happance only when its load then if i select the next item of first one it would not work properly.
