I have a dropdown in the InsertItemTemplate of a FormView that I need to add code to it's SelectedIndexChanged property, however I can't seem to find any way to do this.
For example, if the dropdown was not in the FormView I would simply use...
[Code]....
...but because it's inside the FormView I can't use the above.
i have the following scenario: one formview. when in editmode there is a child formview linked to the other by a column value. i need to take the value of one of the values of parent formview controls and set it to a textbox of child formview in insert mode. I wish to know which event should I use in codebehind to bind both controls? (that escenario will have paging and must keep the binding as if it was master detail)
View 9 RepliesOn my formview I have a drop down list that is populated with the names of the files in a certain directory. This works fine, but when the drop down list selected value is bound to the database field I get the following error :
'ImageFileDropDownList' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I have setup other drop down lists in the same formview populated from SqlDataSources and these all work fine. I can see perhaps why this is an issue because I have not specified a DataValueField or a DataTextField for this drop down that is populated in code (whereas I can for the SQL bound ones) because I'm not sure what these settings would be.
I need to have a "blank" option as well so that the field does not default to the first value in the list.

I have a formview with many textboxes, dropdownlist, labels etc. I want to populate these fields using code and not a datasource.
View 1 RepliesI am using a form view control which has two binded textbox. Now at this level it works fine and the textboxes show the values from database.

View 2 RepliesI am attempting to show/hide a control (txtInpatientType) when a user views individual records on a FormView (frmData) depending on the value stored in another control (txtPatientType). For example, if txtPatientType.Text = "Inpatient" then txtInpatientType.Visible needs to be True. Very simple code follows.

txtPatietType and txtInpatientType are both ReadOnly. txtInpatientType.Visible = false by default.
I have a very complex page with 11 formviews, 1 dropdownlist, and 11 sqlDataSources.I have several issues
Page: This page controls my website users and their info. There are 2 different users with 3 different permissions; users - 1 Primary(account Creator), and the rest; Permissions - View, Edit(Manage), Create/Delete(Author)
Each Formview controls one column in the table.
1st. After Permissions are read, the add, delete buttons are to be disabled if no permission. If the User selected is the PrimaryUser the delete button is disabled. On Page load, the delete button is enabled even though the displayed user is the Primary, when you select another user, then select the primary again, the delete button is disabled, but when you select another user the delete button is still disabled. This should not be!
2nd. I then added a check to see if there was one or more locations, and if there is only one, then disable the edit button that allows a user to assign a user to a specific location. example: if there are 3 locations, you may assign a user to that office location, but if there is only one location, there is no need. I try to disable the edit button in formview, but I get "object reference not set to instance" which is total cr#$ because the button is there in the form.
3rd. When a page loads and all of your sqlDataSources have a Select controlParameter that is determined by a DropDownList, how is the initial record determined other than it is the first record?No matter how I work my code, these issues do not work, and it is very frustrating and holding my project back. I have been working on thes for a week.

I have a formview with an insert item template. I have added two dropdown controls that are databound to two different database tables to this insert template. However, when I click the 'InsertQuery' for the Accessdatasource neither of these controls are available as 'Parameter source options'.Out of interest, if I take these dropdown controls out of the formview and put them on the page they then become available to use.
View 1 RepliesI have a calendar control where a user selects a date and then inputs info into a FormView control. Underneath the FormView is a GridView that shows all data from the SelectedDate on the calendar control. However, when the date is selected, all the information from the table ( from all dates ) is displayed.

I use a GridView control to select the row to display within the FormView. The FormView contains a RadioButtonList to facilitate the selection of one of its values. My C# codebehind contains a "selected_index changed event to grab the values from any of the modified FormView controls. My problem is that it is not picking up the selected radio button. Here's some code:

View 2 RepliesI am doing a library application. I am using a formview control to display and edit the details of an existing borrower.
What I wish to do is to allow the user to enter the borrower barcode into a textbox and select the details of the borrower corresponding to the barcode.
At present I have kept the textbox and a button outside the formview. Once the user enters the barcode in the texbox and clicks the button, the data is displayed in the formview control.
Now, my doubt is that is there a way to keep the textbox inside the formview control itself and use the value(Which should be user input) for selecting the details?
I want to add some functionality into a formview when it is in its "editable" state. I want to have a check box and if a user clicks the checkbox then it makes certain text areas and labels appear inside a table. Seems straightforward except that I am not sure how to access a formview in a code behind and do it when its in the editable state and then I have the consideration of the ProfileDataSource which shouldn't matter because thats not part of manipulating the visual elements inside the Formview.

I have a Formview ('formview1') with a pager. I also have a gridview ('gridview1') linked to a SQL datasource ('History'). I need to set the SelectParameter ('Serial') of the datasource to be the value of a field on the current page in the formview. The value i need to get is in the ItemTemplate and is a label called 'SerialNumberLabel'. So, something like:
<SelectParameters>
<asp:ControlParameter Text = "Eval fromview1.currentpage.itemtemplate.SerialNumberLabel" >
I also need to ensure that the SQL source and gridview rebind when the pager is activated.
