Forms Data Controls :: Detailsview Change To Edit Mode?

Mar 28, 2010

I am trying to handle the detailsview programmatically but I don't know what I am doing wrong. My details view control isn't going into edit mode. My code for my gridview's select button properly loads the data into the detailsview but once the detailsview renders clicking on "Edit" doesn't switch the detailsview contol into edit mode.

This code draws the information from my database and loads the information into the dataview:

This code is in my dvTeamDetails_ItemCommand sub and the beep works:

Forms Data Controls :: Populating Initial DetailsView In Update Mode?

Feb 3, 2011

I currently have a page that is used to insert or update records in a DetailsView using an EntityDataSource control. Insert is working perfectly. However, Updating is not. I have the default view set to insert. In PageLoad, I have:

[Code]....

However, the DetailsView always defaults to the first record in the table rather than the record with ID that is equal to the ID querystring parameter. I am not sure how to make it select the correct record. From spending a while researching, it looks like I might need to use a QueryExtender control on the Entity DataSource, but haven't been able to figure out how to configure the QueryExtender correctly.

There is also perhaps some sort of datasource="stuff", databind() that I could toss in there but again.. not really sure how to proceed.

Forms Data Controls :: DetailsView - Set Textbox Text When Going To Insert Mode?

Jan 19, 2011

I guess I'm not sure exactly how or where to do what I need.

First off - here's what I need - - when the user clicks on the NEW button in the detailsView, I have the User.Identity.name captured in a variable and I need to set one of the textboxes (InsertItemTemplate) named 'txtNew' to that name.

I've tried using the ModeChanging (and ModeChanged) event:
Dim
dv As
TextBox =
CType(DetailsView1.FindControl("txtNew"),
TextBox)
If (e.NewMode =
DetailsViewMode.Insert)
Then ....

However, no matter what, 'dv' always shows as 'Nothing', so I can't change the text of it.

Where do I put the logic and what am I missing?

Forms Data Controls :: Validate A GridView Textbox In Edit Mode?

Oct 17, 2010

I am working with VWD Express and Visual Basic. take this into consideration if you are willing to answer my question. I do have the following code for a GridView.

<asp:GridView
ID="OpenCloseUDTIGameThreadGridView"
runat="server"
AllowPaging="True"
AutoGenerateColumns="False"
DataKeyNames="AutoNumber"
DataSourceID="OpenCloseUDTIGameThreadSqlDataSource"
CellPadding="4"
ForeColor="#333333"
PageSize="100" >
<Columns>
<asp:TemplateField HeaderText="Picture">
<ItemTemplate>
<asp:ImageButton
ID="ThumbNailImageButton"
runat="server"
Width="75px"
PostBackUrl='<%# string.Concat("~/Classifieds/DetailPage.aspx?AutoNumber=",Convert.ToString(Eval("AutoNumber")),"&amp;FlagForm=NoSubmitted") %>'
ImageUrl='<%# IIF(System.IO.File.Exists(Server.MapPath(string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"))), string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"), "~/UploadedImagesClassifieds/NoPicture.gif")
%>' />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
<asp:CommandField ShowEditButton="True" />
<asp:BoundField DataField="TCategory" HeaderText="Category" ReadOnly="True" SortExpression="TCategory" />
<asp:BoundField DataField="TItemTitle" HeaderText="Item Title" SortExpression="TItemTitle" ReadOnly="True" />
<asp:BoundField DataField="TUDTIThreadActualStatus" HeaderText="Actual Status" SortExpression="TUDTIThreadActualStatus" />
</Columns>
</asp:GridView>

As you can see the second cell in each row is a EditButton, and the only cell that could be updated by users is the last one, DataField = TUDTIThreadActualStatus. I just want to know what could be the easiest way to validate the user entry when the row is in edit mode. Is there anyway to validate the textbox control with a validation control or is better to used code behind. Either way may you explain and drop some code if posible.

Forms Data Controls :: How To Fill Unbound Textbox With Data When Going Into Edit Mode

Feb 2, 2010

I have some template columns that have multiple textboxes in them.

There is one textbox for the Date portion of a datetime field and another textbox for the Time portion of the datetime field.

How do I populate those textboxes after the user clicks on the "Edit" button?

My assumption was I could get the data from the label that was displaying the datetime field data, break it down into Date and Time, and then access the textboxes.text property to fill those.

I can get the data from the label control, but when trying to fill the two textboxes with the data, I get Object Reference Not Set... errors.

Im assuming maybe those textboxes are not setup yet during the RowEditing Event?

Forms Data Controls :: Gridview - Column Styling - Class To Define What Textbox Looks Like In Edit Mode

Jun 10, 2010

In the example below I have set the control style to 'controlName' I want to use this class to define what my textbox looks like in edit mode. This works ok, so far so good. The Problem In a button event I add the class "validationError" to this textbox if the data is incorrect. When the grid gets rendered I expect to get 'controlName validationError as the class applied to the textbox. Unfortunately, it seems that the declarative statement overrides this and simply ends up as 'controlName' how I can intercept the application of the declarative class so that I get what I desire here?

<asp:BoundField
DataField="Name"
HeaderStyle-CssClass="headerName"
ItemStyle-
CssClass="itemName"
ControlStyle-CssClass="controlName"
HeaderText="Name"
>
</asp:BoundField>

Forms Data Controls :: DetailsView - Binding Datafield To TextBox On Update?

Jun 29, 2010

I have a bound field in a DetailsView that I want updated with the contents of TextBox2.Text when I update. I have TextBox2 set AutoPostBack True. Cannot remember how to move the contents on update. I tried converting the "Description_Update" to a template field without success.

I can copy and paste the contents of TextBox2 into the DetailsView and it does update as do the other DataFields.

<asp:TextBox
ID="TextBox2"
runat="server"
Height="80px"
TextMode="MultiLine" Width="360px"
Font-Size="Small"
MaxLength="120"
Text=""
Font-Names="Calibri" AutoPostBack="True"></asp:TextBox>
<asp:BoundField
DataField="Description_Update"
HeaderText="Descrip"
SortExpression="Description_Update"
/>

Do I need to use adn Eval or DataBind function or both. I have triued several combinations and do nothing but continue to butcher the database tables.
