View 2 RepliesI'm using the code below to extract data from a gridview and populate it into textboxes for the days and two drop downs for Project and Category.
For some rows in the gridview everything but the category ddl populates correctly. If I click the row a second time the category ddl displays the correct category.
why I have to click twice for some rows? And how do I fix this?
[Code]....
I would like to know if there is a way to debug the gridview and work around the code that is behind it.Right now i'm getting an error when i try to modify a record with this control. So, if any of you guys know a way to get this done,
View 6 Replies 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.

<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AllowPaging="True" PageSize="10" OnPageIndexChanging="countryGrid_PageIndexChanging"
CellPadding="4" ForeColor="#333333" Width="400px" Font-Size="9pt" [code].....
I have a gridview that shows when something is check out. I would like to only show results from todays date and forward. I have done this in Expression Web but when I tried to use the same code in Visual Studios it doesn't work.

In expression web I changed this line from this WHERE [ID] = ?"> to this WHERE [ID] = date()"> and I get the right results.
I have a detailsview with a sqldatasource! This is my update command, but it doesn't seem to work.
[Code]....
i have a webform to take user inputs. i am able to insert the data into database on clicking add button and also able to view the
records in the detailsview which is in the next webform.I have a edit and delete button in detailsview.
Now when i click edit button, i want the selected record from the detailsview to be populated in the first webform where i can update the record. also deleting record using delete button.i am using c# code,datatable and oracle stored procedure here.
I need a complete code reference for Detailsview and Formview using the code only:OnRowCreatedOnRowEditingOnRowUpdatingOnRowDeletingOnRowCancelingEditOnPageIndexChanged OnPageIndexChanging OnSorting OnRowDataBound
View 2 RepliesI'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 radiobuttonlist in a details view. Databinding is happening in PageLoad (if not IsPostback), after a details view item is inserted, edited and upon clicking cancel when in edit mode.Everything works well except when clicking cancel which for some reason the radiobuttonlist appears as empty. The code is surely working because up till OnPreRender the radiobuttonlist contains the required items. However OnRender the list appears as empty.
View 1 RepliesI have a details view in asp.net which I am dynamically replacing some of the controls using code behind (e.g. converting some text boxes to dropdowns). My problem is that I am unsure how to bind these to the field from the database on postback. I.e. I am trying to find the code behind equivalent bind('currency');
I can populate the dropdown with the current value from the database but cannot find how to save a new value on updating the detailsview.
Is Sqldatasource powerful? Is there any disadvantage using it over other controls?
And How to use Sqldatasource from code behind with datacontrols like gridview,detailsview and formview?
Is it possible to completely customize the gridview using sqldatasource from code behind?
I'm trying to add an DropDownList to a DetailsView by code, because i'm writing a solution that let's the user select an table and view your records and edit them, some of theese tables, have a foreign key column and the user must have to select some item in the list.
Below is my sample code:
[Code]....
the code above is working correctly, when the user click in the buttons New or Edit , the DetailsView opens correctly, showing the DropDownlist, but when the user click in the buttons update or insert , an error occurs, the viewState cannot be loaded:
Failed to load viewstate. The control tree which viewstate is being loaded must match the control tree used to save viewstate during the previous request. For example, when controls are added dynamically, the controls added during a post must match the type and position of the controls added during the initial request.
I have a detailsview bound in the code behind file. I want to format the column headers. How can I do that in the code behind file.
SqlCommand Cmd = new SqlCommand(SQLquery, connection);
SqlDataReader Dr = Cmd.ExecuteReader();
dvEstQty.DataSource = Dr;
dvEstQty.DataBind();
Cmd.Dispose();
connection.Close();
connection.Dispose();

procedure TCGI.LoadTV(var tv : TTreeView; s : String);[code]....
TXTARIZATIP.Text=DropDownList3.SelectedItem.ToString(); i think it should be worked but it does not.
View 5 RepliesI have a gridview and detailsview on the same page. The detailsview is defaultmode="insert" and works perfectly (Role, Site and Department are all bound to ddls). The gridview displays information fine and deletes fine - but when i click edit it breaks. But i dont understand why as it is using the methods and data sources as the gridview. I did a test run on this a few weeks back and it worked in visual web developer, lost all the data when i formatted the hdd and now - i cant get it to work, but i am sure its exactly the same. error is
DataBinding: 'System.Data.DataRowView' does not contain a property with the nameXXXX.
It does that on each of the ddls for site, role and department. But the property is there! i can see it when i test my SPROCS and they display / work fine in the detailsview.

We are using gridview to display data and detailsview to show details, update, insert, and delete as needed. I am a bit confused on whether or not htmlencode and htmldecode is needed when storing data from detailsview. Gridviews always use boundfields and I think encoding and decoding is built in. For detailsview we use mostly templatefields (eval(), bind()), some boundfields, and some data is stored in codebehind using e.values[] or e.newvalues[].Here is where I've got the idea:http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.detailsview.itemupdated.aspxIf I use the iteration and htmlencode, detailsview read only mode displays decoded data. However, gridview displays encoded data and of course update mode of detailsview. So, it seems like detailsview using htmlencode and htmldecode somewhat, but I am not clear as to what degree and what would be the best way to handle it.
View 2 RepliesI am designing a web page that allows for the maintenance of a single table - so I have some controls that allow the user to specify some search parameters, a button that then populates a gridview with the result of the search meeting the search parameters, and a details view for inserting and updating specific records. The gridview and detailsview are bound to appropriate sql data sources.All pretty standard.There is also a "reset" button that clears the results of the current search - sets the visibility of the gridview and detailsview to false, and clears the search parameters. Again, pretty standard.What I have done is when the user goes to insert a new record, the gridview and search parameter specification controls are hidden, and the details view displayed. If they cancel the insert operation, the details view is hidden, and the search parms and gridview displayed - but what I am finding is that there are situations when a previously populated gridview is displayed. Here's the situation:1) Specify some search parameters, click search - and the gridview appears, with the appropriate records displayed.
2) Click on the clear button (oops - I didn't want to search, but add a new record). The gridview disappears, the search values are cleared out.3) Click on the insert button - the detailsview opens in "insert" mode.So far, this all works well, and is intuitave to the users.4) Click on the "cancel" button on the details view. I hide the details view, and show the gridview and search parameters. The gridview appears - with the results of the previous databinding still in it.My question is: Is there an easy way to "unbind" the gridview? From my understanding of how the datasource to gridview (or detailsview) connection is done, there is a datatable "behind the scenes" that manages the two way data binding. I also assume that data that has been bound to a gridview is carried over in the viewstate - it would be nice to clear out unneeded data in that.
I'm using code to convert items in a Datagrid row from UPPERCASE to Title Case. It works good, but the problem is if it comes across a hyperlink field, it will put in a blank value. Not sure why its doing this, but here is the code below. Wondered if any one has came across this problem and managed to solve it?
The code:
aspx page:
<asp:GridView ID="SectionsGridLevel1" AutoGenerateColumns="False" onrowdatabound="SectionsGridLevel1_RowDataBound" emptydatatext="No data available." runat="server">
<Columns>
<asp:hyperlinkfield headertext="Section - click to view sub-sections" datatextfield="SectName" datanavigateurlformatstring="BrowseSections2.aspx?type=sect&list=1&level=2§ion={0}" datanavigateurlfields="SectID" />
<asp:hyperlinkfield headertext="View" Text="View All" datanavigateurlformatstring="BrowseSections2.aspx?list=1§ion={0}" datanavigateurlfields="SectID" />
[Code]....
the below works in Internet Explorer but not firefox.
protected void Page_Load(object sender, EventArgs e)
this.GridView1.Attributes.Add("bordercolor", "c3cecc");
I am trying to arrange the information from a SQL record into a 3 column by 3 row table to fit the form presentation that I want. I have placed on the page 3X3 table and then tried to place a detailsview in the first cell for the first picture called P1dv.
I have place a detailsview in the last cell that would control the paging of information called Controldv. I need to fiqure out how to link P1dv paging to Controldv page action. I am using visual web dev. 2005. I am not updating or editing these are read only views.
example of what i need the form output to look like:
picture1 picture2 picture3
name1 name2 name3
Contact1 contact2 contact3
what i ave coded as of now:

I have a master/detail page using a gridview as the master, and a detailsview as the details. The gridview is set to select a record, and the detailsview picks up the ID and you can either edit that record, or add a new one.The detailsview is set up with various template fields, and if everything on the page is visible, it works OK.However, I wanted to hide the Gridview when the user in working with the detailsview. But if I do that, the detailsview doesn't update the record.
