Forms Data Controls :: How To Empty A Textbox In Detailsview Codebehind

Oct 27, 2010

I have a detailsview with three textboxes as itemtemplates. Each for holding a different date. 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.

Asp:

[Code]....
In the code behind is the following for linkbutton on click:

[Code]....

Now, the problem is that no matter which linkbutton a user clicks all three textboxes are cleared/emptied. Why?

Forms Data Controls :: How To Move A Detailsview Sqldatasource To Codebehind

Apr 5, 2010

I have working code similar to the following in my Detailsview:

<asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:DATABASE %>"
SelectCommand="SELECT Id, PracticeId, FirstName, LastName, Notes FROM Providers WHERE Id=@Id"
UpdateCommand="UPDATE Providers SET
PracticeId = @PracticeId,
FirstName = @FirstName,
LastName = @LastName,
Notes = @Notes
WHERE Id = @Id"
InsertCommand="INSERT INTO Providers (
PracticeId, FirstName, LastName, Notes
) VALUES (
@PracticeId, @FirstName, @LastName, @Notes)">
<SelectParameters>
<asp:QueryStringParameter Name="Id" QueryStringField="Id" Type="String" />
</SelectParameters>
<UpdateParameters>
<asp:Parameter Name="Id" Type="Int32" />
<asp:Parameter Name="PracticeId" Type="Int32" />
<asp:Parameter Name="FirstName" Type="String" />
<asp:Parameter Name="LastName" Type="String" />
<asp:Parameter Name="Notes" Type="String" />
</UpdateParameters>
<DeleteParameters>
<asp:Parameter Name="Id" Type="Int32" />
</DeleteParameters>
</asp:SqlDataSource>

I would like to move all of this to codebehind so it's easier to work with programmatically. For instance the PracticeId is a selection from a dropdownlist that is populated from another table... i need to determine what the current selection is first so i can display the record / bind properly.

Forms Data Controls :: Detailsview Mode Updates Read Only Field To Null Or Empty

Sep 10, 2010

I have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?

Forms Data Controls :: Find And Set DetailsView Controls In Empty Data Template In Gridview

Oct 31, 2010

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";

Forms Data Controls :: DetailsView EmptyDataTemplate After Insert Defaults To Empty Insert Screen

Jan 27, 2010

In my detailsview, I have an emptydatatemplate set up to allow users to enter new records. The code works. However, once the record is inserted, the detailsview defaults to a standard insert screen. I know this will cause confusion for the users. I would prefer the detailsview to either show in edit mode or a read-only mode. I have used detailsview.changemode and detailsview.currentmode in the custom sub created for the add new button of the emptydatatemplate- neither of which do what I was hoping. It would be even better if when there was no data, it defaulted to the insert screen (which seems like that should be an easy, no-brainer way for .net to function) but it doesn't. Or, I don't know how to accomplish it.

I don't want to force the user to click cancel after inserting an item through the emptydatatemplate just to be able to use the detailsview for other records.

Forms Data Controls :: DetailsView Accessing Textbox Through Code Behind?

Jan 25, 2010

I'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, 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 :: 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.

Forms Data Controls :: Set Text Property Of TextBox In DetailsView To Query String Value?

Sep 19, 2010

I'm tyring to write a simple DetailsView only used for inserting new records that will pre-fill a textbox with a query string value. Here's the DetailsView:

[code]....

All I want to do is set VenueID_FK.Text to = the "VenueID" querry string. I also want the user to be able to see the VenueID number as they are filling out GridView1.

I know this is probably a simple thing, but I am very new to asp.net. I thought I could handle this in the page load event, but when I try something like this

TextBox VenueID_FK = (TextBox)DetailsView1.FindControl("VenueID_FK");

And then follow by setting the Text property programitically. I've accomplished something similar to this on a different page using a FormView, but only for ReadOnly mode and it was handled in the databound event on that page.

I get the error "The name 'DetailsView1' doesn't exist in the current context." when trying to do the above mentioned. When trying the same line in the databound event here, I get the same error.

This is probably something very simple that I've over looked, but I have a template field in a details view. In the field there is a html <p> tag that is bound to a database field. The database field is set to nvarchar(max) and will usually be very long.
