Forms Data Controls :: Bound DetailsView Not Updateing SQL Dataset
Apr 30, 2010
I am using a DetailsView component (dvExpertsData) bound to a SqlDataSource (sqldsExpert) with a field that has a ItemTemplate (Field[9]) with a checkbox component (chkbxAvailable) assigned to it. The idea is to have only this item updated out of all the data presented, so I do not have a requirement for editing an other data. sqldsExpert's SELECT query is a call to a stored procedure as is the UPDATE query.

Codebehind: creating dataset, getting data from sql with adaptor and filling into dataset object, then setting detailsview's datasource.

My question is, what to do inside the detailsview update event function to able to edit and update data. My method can be wrong too.

I have a dropdownlist in the edititemtemplate of a detailsview. The dropdownlist is bound with an objectdatasource. The detailsview is bound to a seperate objectdatasource which connects it to the insert method. When the page loads the dropdownlist is bound properly. However, when I make a selection and select insert I get the following error: Could not find a property named 'DeptID' on the type specified by the DataObjectTypeName property in ObjectDataSource 'objCurrentProduct'. I've tried to remove the SelectedValue='<%# Bind("DeptID") %> attribute. I can then insert without an exception being thrown but the selected value of the dropdown is not recognized. Here is the code:

I want to add boundfield to the Detailsview control at the run time. The data is coming from the dataset, which is fetching data from SqlDataAdapter. I tried using the following code
string st = "select * from tbrob,tbemp,tbcty,tbcmp where robfircod=" + TextBox1.Text.ToString() + " and robempcod=empcod and robctycod=ctycod and robcmpcod=cmpcod";

If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs

I have a GridView populated by an ObjectDataSource. I also have several DropDownLists filtering the ObjectDataSource. I found a link providing a way to export a DataSet (or DataTable) to Excel here:
http://msmvps.com/blogs/deborahk/archive/2009/07/23/writing-data-from-a-datatable-to-excel.aspx
ow I can ensure that filters applied to the ObjectDataSource when the method is called are applied. In short, how can I ensure what the UI is displaying is what the file will include when exported?

I have a dropdownlist in a Usercontrol defined in a table as:
<asp:DropDownList
runat="server"
id="lstDIDFCM"
Width="135px"
AutoPostBack="true"
></asp:DropDownList>
i have the AutoEventWireup="True"; I have a breakpoint in the code behind on the SelectedIndexChange event.
The event does fire but the index is not changing. No matter what item in the list I select, the SelectedIndex always = 0. The list is bound to a dataset and the DataTextField and DataValueField are both set to the same value. Why is the index and SelectedValue not updating?

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'm hacking my way through ASP.Net WebForms, coming from VB.Net WinForms. I was hoping the transition would've been more seamless... it is not.
I have a GridView (Paging enabled) bound to a DataTable, filled with Joined tables from an Access 2000 DataBase.
The GridView and DetailsView are bound to the same DataTable.
In the GridView's SelectedIndexChanged Event I have the following:
vb.net Code:
' dtvSelected is the DetailsView' dgvJobTOF is the GridView Me.dtvSelected.PageIndex = Me.dgvJobTOF.SelectedIndex
When the page loads the first item in the GridView is also displayed in the DetailsView.
I've added a "Select" button in the GridView and when it is clicked the Data in the DetailsView remains the same regardless of the selected GridView row.
DataBinding Method:
vb.net Code:

I'm trying to populate a date from a bound text field in a DetailsView. I keep getting a error when a DBNull is in the column. How do I avoid the DBNull when populating the text field.My code is as follows:
<asp:TemplateField HeaderText="CBYD Clear Date">
<EditItemTemplate>
<asp:TextBox ID="CBYDExpDate" runat="server" ReadOnly="true" Text='<%# IIf(Eval("CBYDDate") is DBNull.Value,"", String.Format("{0:MM/dd/yyyy}", Eval("CBYDDate").AddDays(30)))%>' />

I just can't figure out how to approach this, but this is what I want, would be I have a database-table containing an XML-field. Using LinqToSql I succesfully bound this table to a GridView and a DetailsView control.ow I wrote a WebUserControl that renders a bunch of textboxes, and has a method 'Serialize' that returns the XElement-object that I can use in my codebehind to assign it to the LinqToSql-property to save it to database. It also has a public property 'Xml' (type string) that I can use to Bind() the xml-string from the database to it, so the WebUserControl can prefill it's textboxes.

I am using the DetailsView Control to read a LastUpdatedDate field (which can be null until an update is performed) from the database. The LastUpdatedDate is of type DateTime saved in UTC. With the DetailsView control, I can use the NullDisplayText property of the boundfield to safely display an custom message. However, once converted to a template field, that property is lost. Now, how would I display that message if the field is null as I am also formatting the date for display to show in local time.

I've been using the Item Inserted event for my data controls, such as details view. I'm wondering if there are advantages to doing this with the data sources instead of the data control. There is a lot of overlap in the events provided by these two types of controls. Are there advantages to using the events raised by the data source instead of the ones raised by the data control itself. Should I be using the events raised by the data source instead of the control used to enter the data?

I have a foreign key (TeamID) in a GridView. I use a TemplateField to display it as the lookup value (TeamName) in a label, and a dropdown for editing. When row is selected and SelectedIndexChanged is fired, I want to access the TeamID. I can get the TeamName from the label. I tried putting the TeamID in DataKeyNames, but that fouled up my dropdown when saving (it reverts to the original value). So, how can I get the TeamID?

When I bind my listview with a typed dataset the textbox is filled with spaces up to its max length.
For example if I have "ABC" in the typed dataset and the textbox has a max length of 5 it will actually bind "ABC ".
I know I could trim it ont he databound event, but I shouldn't have to.
