I am using a DetailsView Control and have a "MemberStatus" field.
When using the templates in edit mode, I am using a dropdownlist to change the member status.
e.g.
<asp:TemplateField HeaderText="Member status:" InsertVisible="False" SortExpression="MemberStatus">
<EditItemTemplate>
<asp:DropDownList ID="ddlMemberStatus" runat="server" DataSourceID="adsMemberStatus" CssClass="eitField" DataTextField="MemberStatus"
DataValueField="MemberStatusID" Width="120px" SelectedValue='<%# Bind("MemberStatusID") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label6" runat="server" Text='<%# Bind("MemberStatus") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
What I would like to achieve is, if the MemberStatus is changed during edit mode, e.g. from "Active" to "Deceased"
I would like to enable certain fields e.g. txtBoxDateDeceased, and attach a RequiredFieldValidator for the textbox field.

I have a Details view where I want to have a multi-select value, with the choices driven from another table.I need to iterate through the check-boxes in the list, and I do that by using a DetailsView1.FindControl("MyCheckBoxList") to find the check box list.The challenge I'm having now is that if I name the CheckBoxList differently in each of the templates (Item, Edit, Insert), then they each need a separate handler to find the control and iterate through the checkboxes. I can't find a method to fire a handler
View 2 RepliesI've been struggling with trying to figure out how to do this for about 2 weeks now. I have a DetailsView with several template fields in it. The first field (Unit_Code) is a dropdownlist item where the user would select a Unit based off the Unit_Code's Unit Name. Further down I have a field named (System), system needs to get it's value from the selectedvalue or selectedindex that the user selected in the (Unit_Code) dropdownlist. I have another dropdownlist item (Component) that will need to get the selected value from System to sort on, so once I have the first Unit_Code to System figured out I should be able to figure out the System to Component part seeing as it will basically be doing the same thing.

I use the DetailsView control to display selected employee's data for HR. The list of data elements has gotten pretty long so I thought I'd put some tables & panels inside the ItemTemplate and EditTemplate. Testing with NO code behind in effect works perfectly on display & update. Now I need to manipulate some stuff in the code behind which requires me to cast the controls I'm after. However old cast code doesn't work (it says the row index doesn't exist).
First is a clip of the DetailsView which gives me 3 nice columns.

I'm trying to add an DropDownList to a DetailsView by code, because i'm writing a solution that let's the user select an table and view your records and edit them, some of theese tables, have a foreign key column and the user must have to select some item in the list.
Below is my sample code:
[Code]....
the code above is working correctly, when the user click in the buttons New or Edit , the DetailsView opens correctly, showing the DropDownlist, but when the user click in the buttons update or insert , an error occurs, the viewState cannot be loaded:
Failed to load viewstate. The control tree which viewstate is being loaded must match the control tree used to save viewstate during the previous request. For example, when controls are added dynamically, the controls added during a post must match the type and position of the controls added during the initial request.
I would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.
1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.
2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.
1. Link button (on click) in the gridview footer (works fine)
protected void LinkButton1_Click1(object sender, EventArgs e)
{
string zupa1;
zupa1 = ddlSelectEmployee.SelectedValue;
try
{
DetailsView zupa = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1"); TextBox zupa2 = (TextBox) zupa.FindControl("txtInsertEmployee");
zupa2.Text = zupa1;
}
catch
{
}
DetailsView dettraining = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1");
TextBox training = (TextBox) dettraining.FindControl("txtTrainingType");
training.Text = "4";
}
2. EmptyDataTemplate.FindControl - can save record but cannot access txtInsertEmployee and txtTrainingType
DetailsView zupa = (DetailsView)gvTraining4.EmptyDataTemplate.FindControl("DetailsView1");TextBox
zupa2 = (TextBox)zupa.FindControl("txtInsertEmployee");TextBox
training = (TextBox)dettraining.FindControl("txtTrainingType");"4";
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?

View 2 RepliesI have a webform with a DetailsView control. In the DetailsView, I would like to update the headertext (showing field names) to a "friendly name"
I also have a cross-reference table which has a field name with a matching friendly name.
Is there some code to get my DetailsView control to look up the field name, and then display the friendly name on my form.
