Drop down list in Form view returns error when value in bound field (data binding
I get the following error when I click edit to edit the details in the web form:'ddlUserRestrictionType' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value I would like it to accept any value which currently exists in the database. Is this easily achievable?
With what you've posted, all I can tell is that you are trying to set the SelectedValue of a ddl to a value that does not exist in the list. It would be helpful if you can post some code and the expected values of this control.~ Timwww.bucketo...Can a DataSource set the default value in a DropDownList (or the list fetch the value from a DataSource)?
I have a DropDownList that gets its values from a DataSource-control. Nothing magic so far. What makes me scratch my head is that I need to set the default (selected) value in the drop down.
As the values come from a data source, I do not know the key/value/index of the default I. Is there a possibility to make the drop down "ask the data source" which key should be the default (that is, only if the drop down is populated the first time, of course)?

I've created a custom drop down list by inheriting dropdownlist, and done a number of modifications to the DataSource property. The problem is that when I set the DataSource on the dropdown list it binds to the DataSource Previously set. Consider the following form: My modified dropdownlist is on the left, Each of the buttons modifies the data source and causes the dropdownlist to databind. However only button 153 causes any values to appear in the list (this is intended). Here's a scenario:The page loads and the Drop Down List empty because no datasource has be...DropDownList DataBinding to an object datasource but with itemlist from XML DataSource???
Hi,Im trying to get a solution to the following problem:I've got a number of DDL (DropDownList) controls on my page and I want each control to have an option range of -9 to 9. However I also want the SelectedValue to be data bound to an object datasource control.I was initially populating the DDL item list with a recursive routine which added the itemlist to DDL controls on the page and then programmatically set the selected value of each control from an object instance. To update the database I was applying the DDL selected values into the update method parameters of my obje...Gridview Search Without Object Datasource Filter ParametersGridview Search Without Object Datasource Filter Parameters
Couple weeks ago I read a article about highlighted search in Gridview (http://blog.evonet.com.au/post/2008/06/25/Gridview-with-highlighted-search-results.aspx) and in my project I used things I learned but now things changed I have a gridview and in code I give its datasource so because I dont use any objectdatasource I dont know where to write my filtering parameters. Is there anyway to use filtering without objectdatasource, or is there a way to give objectdatasource an source then bind it to my gridview.

I have searched around for some answers to this. Any links would be greatly appreciated.
To start, I'll explain the data model. I have a members table that has a typeId field. TypeId refers to a lookup table with the fields TypeId, TypeName...etc. I am using Linq to SQL to map the database.
Now in my aspx page, I'd have a formview that binds to the members table. In the formview's edit mode, I'd like to have a drop down list that populates itself from the values in the type table (with TypeId as value and TypeName as Text) but sets the selected value based on t...dropdown list datasource

ok - I am fairly new to the .Net way of doing things - so maybe the answer to my question is staring me in the face, but I need some help to see it! Thanks in advance for any who read this! :)
I have a form with a DataList on it. in the Item template, I have many data controls. (CheckBoxList, DropDownList, etc.)
I have set the Datasource of the DataList to an ObjectDataSource (odsDetails) - and for fields that I can bind directly to controls (textboxes, etc) - this works great!
However, I have other queries that populate the items in the dropdownlist and the...Custom Datasource Controls Vs. Object Datasource Controls
Hi folks,I am a web developer developing pages in the project. I need to integrate the front end pages with the backend API. Active directory is being used as the database system for our project. I only use the API and the methods offered by it to interact with the data.For all the operations on the data, I have methods that I can call from the API (viz. Create(), Delete(), Modify() etc.). For connecting the data to my frontend data controls (viz. GridView, DropDownList etc.) I can use Object Datasource Control. I also read some articles about Custom Datasource controls. Now, I am having a d...How to set DDL's selected value by datasource other than DDL's datasource
I have three TemplateFields in a Gridview. In each, the ItemTemplate has a label whose text value is bound to the GridView's DataSource. But in the EditItemTemplate the DropDownList is populated with a separate DataSource. This is a fairly common setup, so that wasn't too much to deal with.
What I need to do is, when the GridView goes in to Edit mode and the DropDownList is populated and displayed I want the value that was in the bound label to be the default selected value in the DropDownList. As it currently is, the DropDownList renders with "Select..." as the defau...gridview populated from datasource but want to add template column with different values from another datasource
