Forms Data Controls :: Dynamic DetailsView - Adding Template Field By Code?
Feb 11, 2010
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 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

I'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.
My aspx page code is below:

I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.
After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...

I have a gridview which the columns are created programmatically.
When a button is click i will clear all columns and add the columns that I want. Im adding a boundfield which is not a problem. When I add a template field, I must add also the item template which is my problem.
How can I add a item template in the template field I created which is binded in my datasource. Also what event handler should I use to do this.
Here's the part of my code:
[Code]....
Someone know how can I bind a label item template from the datasource. The label item template should be firstname + middlename + lastname.
If im not doing it programatically, it will be just concatenating eval(). But how can create item template and bind it programmatically?

Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.

Have spent hours trying to create a Dynamic Data Field Template holding a DropDownList which is extended by the AJAX Cascading DropDown extension.Final form holds multiple cascading dropdown boxes. User selects Country (Land) then Postcodes, Counties (Provincie) are populated. Once postcode is selected then towns (Plaats) are populated. The problem I am now facing is that the viewstate for the dropdown lists is not being saved/restored after an insert action or custom validation error. So basically the dropdown lists are being reset to their default values.Some code (if missing parts, just ask and I will post them) - Don't mind the code structures etc... needs some refactoring :)Attribute I created:

I have a DetailsView control in a VS2010 project. There are 20 fields, most of which have been converted to template fields. However, when I right click the control and choose Edit Template, I only see the first 15. I cannot choose to edit any of the template fields beyond that. The fields work when I run the project, but I cannot edit them via the designer. Is this by design or is something corrupted?

The Detailsview has a template containing a textbox for one of it's fields.When an item is selected in the Gridview, I want to set a property of the textbox. How do I do that? I've tried Findcontrol for the item during Prerender of the detailsview. I've also tried many other things. Below is a portion of my aspx code followed by my VB code.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="LU_DutyStations_ID" DataSourceID="SqlDataSource1">
<Columns>
asp:CommandField ShowSelectButton="True" />
<asp:BoundField DataField="Duty Station Code" HeaderText="Duty Station Code"

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 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.

FileField.PostedFile.SaveAs("directory")

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 small application which allows publishers to update some information at will, one of the problems I have encountered is that sometimes they want to put in a url to certain section within the site.
The url expands the div, and I have this as an expandable div (vertical) and have been using the word-wrap:break-word to put wrap the url.
how to make the user choose what text they want to use and behave like a hyperlink. I was looking for this to be done in the detailsview edit mode.

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?
