Forms Data Controls :: Find Control Inside A View Of Multiview Using Javascript (document.getElementById)
Nov 19, 2010i am using the multiview control inside a page and i am trying to find a control using the javascript function document.getElementById. My Problem is that the function returns null cause it cannot find the control. When i open the code of the page from the browser the active view is not rendered so I think thats the reason why I am getting a null value from the function.
On the HTML code is rendered only the first view or the view that is activated on page load.
Is there any way to find a control inside the view using javascript? or I am doing something wrong?

Forms Data Controls :: DetailsView DropDownList Do Not Find ListItems Entries?
Mar 30, 2010I am using Visual Studio 10/ASP4 but I am sure this problem is me. I created a program and got it all working. GridView and DetailsView, edit, insert and delete all works. :-)... I have spent 4 solid days attempting to have a simple DropDownList with three items on it EDIT a record. Lots of GOOGLeing for suggestions. It just will not work. The insert dropdown works fine(thats how I created the record). I wrote a new simplified program with just the detailsview and the edititem dropdownlist. Still can't get it to work. The detailsview data has a record and the "mode" field (char(20)) has three letters "FTP" in it. The letters display on the Detailsview. I can edit fine but when I add the following drop down list the page aborted with a
"'DropmodeEdit' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value"
Yet there is only one record and it HAS "FTP" in it! The list has FTP in it? I just don't get it, why?
I added an ondatabinding routine and breakpointed it in the try/catch and found the selectedindex pointed to the correct entry and the items list had the correct entry with no spurious data or spaces. The data being passed displayed good in the detailsview, Am I correct in assuming that is bound to the dropdownlist automatically? or is there some majic that I did not get from Rob Burke?
<asp:TemplateField HeaderText="mode" SortExpression="mode" >
<EditItemTemplate>
<asp:DropDownList DataValueField="mode" DataTextField="mode" ID="DropmodeEdit" Runat="server"
OnDataBinding="mode_OnDataBinding" AppendDataBoundItems="True"
[Code]....
I have used a dropdownlist once before with a datasource instead of listitems, this should be easier?

View 1 RepliesForms Data Controls :: Find And Set DetailsView Controls In Empty Data Template In Gridview
Oct 31, 2010I 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";

To avoid the option of users entering invalid values the textboxes are disabled and the user can use a calender control to fill the dates. Because the textboxes are disabled I added a linkbutton to empty a date, if the user decides to clear it.

Forms Data Controls :: DetailsView Accessing Textbox Through Code Behind?
Jan 25, 2010I've been playing with a certain detailsview for most of last week. This particular control is located within a panel that is hidden until a user clicks a linkbutton on a gridview. Then the panel's visible property is set to true and the detailsview is populated based on the commandargument passed through the link button. What I've discovered is that with each postback, the datakey or control parameter, still not sure which or if both, is lost. I've discovered a lot about ViewState and how controls work and am a bit surprised that something as common as using a detailsview within a gridview wouldn't be handled better than it is now. I have been able to get the proper information to build a correct select statement when the user decides to edit a record. I am now working on an update statement, but for some reason while I have the right key to update the right record, I am unable to access the user-generated data that was entered in the details view.
For instance, I select record with ID of 1 in the gridview. It pulls up the detailsview and I can view it. I then click edit. The correct record is still there. (It was previously going to default). When I enter new text in a textbox and click update, the app still knows I am working with record #1 but doesn't seem to be able to find the textbox control. I have currently hard-coded a value into the field just to see if I could actually get the record to update and it did. I am using an OnInit to cause the sub to run and think this might be the problem. However, I have been unable to find a better way around this.
Here is the sub that executes on the OnInit() of the detailsview:
Protected Sub notes_binding()
If notesDetail.CurrentMode = DetailsViewMode.Edit Then
sqlNotesUpdate.UpdateCommand = "UPDATE [Oilchange_Notes] SET [notes] = '" & CType(notesDetail.FindControl("notes"), Textbox).Text & "' WHERE [vehicle_id] = " & Session("unitNumVal")
sqlNotesUpdate.UpdateCommandType = SqlDataSourceCommandType.Text
sqlNotesUpdate.Update()
End If
sqlNotesUpdate.SelectCommand = "SELECT * FROM [Oilchange_Notes] WHERE ([vehicle_id] = " & Session("unitNumVal") & ")"
End Sub
And this is the error I get: Object reference not set to an instance of an object. If I'm correct about why it's not pulling the actual value or even acknowledging the control exists and is actually 'notes' (it is), then at would point would be the best to place this code?

Forms Data Controls :: DetailsView - Set Textbox Text When Going To Insert Mode?
Jan 19, 2011I 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 :: DetailsView - Binding Datafield To TextBox On Update?
Jun 29, 2010I 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.
