I'm trying to find an autogenerated delete button in a detailsview using this code but it is not working:
[Code]....
I 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"

I have used a dropdownlist once before with a datasource instead of listitems, this should be easier?
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 gridview with a template field column. In the edittemplate of that column i have a textbox. In the next column of the gridview i have a button. When i click the button i need to find the value of the before mentioned textbox. I do it like this:
gridview1.selectedrow.findcontrol("textbox1"). This sometimes work just fine and without a problem but sometimes it seems it can't find that control and throws a null reference object. The error it's random like i said, sometimes just work and other just don't work...

View 1 RepliesHow Do I prepopulate A databound textbox in detailsview. When I place my text in the textbox the error says "Cannot enter 'description' into database insert fails.
View 1 RepliesI 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?
I have a detailsview with editautogenerate. When I click "edit" to update the related row; showed up textboxes way narrow around 100px width.
My question:
Is it possible to enlarge edit mode textboxe size. I could not find in dietailsview proporties/editrowstyle sections...
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?
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?
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.

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.
