Duplicate Data in Gridview and Updating textbox in DetailsView
View 2 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:

In the code behind is the following for linkbutton on click:

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 have a DetailsView control where I use templatefields. One of them are textcontrol tempatefield and dropdownlist templatefield.
What I want to so is, when I select let's say "Dollar" value in DropDown list, textcontrol text to be assigned "USD". Basically, text property of textcontrol to be asggined based on dropdownlist selected value.
I am trying to use something like this but it gives me an error:

I have a DetailsView Control, inside as a template a TextBox. I need to findout the value for a TextBox when Inserting data Event handler-, _ItemInserting. The script does not work.
<asp:TemplateField HeaderText="Profile" SortExpression="ContentAuthor">
<ItemTemplate>
<asp:Label ID="uxContentAuthorDisplayer" runat="server" Text='<%# Bind("ContentAuthor") %>'></asp:Label>
</ItemTemplate>
<InsertItemTemplate>
<asp:TextBox ID="uxContentAuthorInput" runat="server" Text='<%# Bind("ContentAuthor") %>'></asp:TextBox>
</InsertItemTemplate>
</asp:TemplateField>
CODE BEHIND
protected void uxInsertAuthor_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
//// Find control on page
TextBox myAuthorProfile = (TextBox)uxInsertAuthorInput.FindControl("uxContentAuthorDisplayer");
// Set a default value in Data Base if field has been left empty (DB field NOT NULL)
if (string.IsNullOrEmpty(myAuthorProfile.Text))
{
string myAllert = "Field is NULL";
}
else
{
string myAllet = "Field is NOT NULL";
}
}
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 have a listview that is retrieving some values from a database and showing them. The information are; product name, price, etc. At the end of each row, I have a textbox and a button. Within the textbox the user is able to insert how many items he wants of that particular item and by clicking the button I want the value from the textbox retrieved. It may be relevant to mention that
with the button is a event attached (OnClick) which is where I want the value of the textbox to be retrieved. The part that is giving me problem is retrieving the textbox value for that specific row when the button is clicked.

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.
they could provide with regards having a word count of a mulitline textbox that is found within a DetailsView? I have tried using JavaScipt and a this [URL] but I don't seem to be able to get it working within that DetailsView,
View 2 Repliesim using visual studio 2008, c#, asp.net, sqlserver to develop website. my problem is i want to change textbox control in detailsview when editing and inserting to other controls such as dropdownlist or radio button. is there any possible way to do it? i've try using edit item template, its work only to change it to other control but not working to bind it to database.
View 7 RepliesThis 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. When the text is loaded into the <p> tag, it is not wrapped and does not go onto a new line when it reaches the edge of the screen.
View 1 RepliesI have a dropdownlist("ddlTemplate") control and a gridview("gvPlanning") control with 1 BoundField column, 1 TemplateField column and remaining columns will be generated dynamically from database.In TemplateFiled Column i have 3 image buttons viz: Edit, update and cancel.Gridview will be populated based on the selecteditem of dropdownlist.
if i click on edit imagebutton, i need to add textboxes dynamically in all the columns of that row except first 2 column. And if i click on Update imagebutton i need to retrieve the textbox values.we can add template field column for textboxes also, but why i am sticking to this method is.. the number of columns changes depending on the selecteditem from the dropdownlist. Eg: If i select india from dropdownlist the number of columns in the gridview would be 4 and if i select UK from dropdownlist the number of columns would be 9 likewise.

I´m trying to link the gridview to detailsview and I used this page as my inspiration:
http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.
I have a gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.
