Forms Data Controls :: DetailsView Not Displaying Data?
Jul 19, 2010
Vista Sp2/VWD 2008 Express
Structure:
Simple List/Details combination of aspx pages.
Issue: Data not displaying in DetailsView web form control. (Details view control doesn't display at all although it's Visible and Enabled properties are set to True.) Other things such as textbox and hyperlinks do display on the page.
I'm feeding a QueryString from a user defined(hyperlink) column in a DataGrid located on the parent(list) aspx page.
The DetailsView aspx page has an object data source pointing to a table adapter that has a query defined that is expecting a parameter of type INT. The parameter source is coming from Request.Querystring. As noted above, the DetailsView control is not displaying when the page is loaded. I've alternately fed the ID from Request.QueryString to display in a textbox on the page; the ID parameter is present and displaying in the text box.
IF the ID Integer needed by the DetailsView's ObjectDataSource is making it to the page and if the ObjectDataSource is working(I can test preview data) I'm wondering why the Details view is not displaying, and displaying with data.

How can I display edit and new buttons without duplication in a detailsview control? This is a question from a past exam paper for 70-562. Part of the question is below:
"The company CIO assigns a task to you. According to his requirement, you must make sure that the users can insert and update content in the DetailsView1 control. Besides this, you have to prevent duplication of the link button controls for the Edit and New operations. At line 3, which code segment
should be inserted?"

I am persevering with visual developer express 2010 whilst learning visual basic from hello world stage onward. In the meantime I have a difficulty . I am trying to display a range of data in details view which is being fed a parameter from a dropdown list. I cannot seem to come up with a query that will pull over all data from a column that is less than a certain number and then display it with distinct values in the dropdown. for example I would like say to pull over height data where it displays all data below 20m all data below 30m etc. is this possible without heavy coding?

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.

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 built a set of custom business objects that I have successfully bound to the GridView and DetailsView controls using the ObjectDataSource. I have been able to provide insert/update/delete functionality and all is working as expected. However, I am trying to wrap this functionality into a custom user control that allows the consumer to specify a table name and a list of column names and have it build this functionality on the fly without regard to the table structure (ie...available columns). I have been able to successfully get the GridView and DetailView to build the columns from code behind and I had all the CRUD working while using 2 panels to show/hide the GridView and DetailsView controls, but I wanted to add some AJAX ability to the control using Matt Berseth's modal popup example to make the interface slicker. The problem I am having is that the EditItemTemplate for the DetailsView control has to be specified in the code behind (because of the flexibile nature of the columns) and I can't figure out how to bind the data from code (rather than having the columns defined and bound in the markup). For all intensive purposes, I am trying to find the code behind counterpart to the following code snippet that binds the data to the textbox:

I have a database containing a table with about 700,000 images so I recently enabled Filestream. However, I can't figure out how to render the images.
I have an Imagefield control within a Detailsview which is using an .aspx file to render the image through the DataImageUrlFormatString (which is typical). In my select statements I tried changing the binary field containing the image from objectdata to objectdata.PathName() per the Microsoft documentation but this does not work. I get the red X image box.

Note: i handle DetailsviewItemUpdating,DetailsviewItemInserting events to do some custom checks.

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 slight issue I awas trying to fix for 2-3 days, but nothing I try works.
The scenario:
DetailsView control in edit mode, I pass parameters to the SqlDataSourceProducts (edit.aspx?id=2) and the data source selects the appropriate data and fills in the DetailsView form.
Except two drop down lists. These two DDLs (DDL2 and DDL3) are dependent on the previous DDL (DDL1) in the DetailsView.
when the selected value of the DDL1 changes, DDL2 and 3 change their lists and get bound to the database.
The problem is: when I edit something from the database, DDL2 and 3 appear empty and when I update any other field and leave these, they get blanked in the database.
My goal is to set the selected value of DDL2 and 3 to the values in the database WHERE ID = QueryStringField="id".
I can go for not binding the data unless the field is changed, but does not sound professional and user friendly.
code:
The SqlDataSource used to select the parameters from the table and populate the DetailsView
[Code]....
The code of the fields that hold the DDLs in the DetailsView control
[Code]....
The codebehind:

[Code]....
I want to show FNature instead of FNatureID in the selected mode as Label and in Edit mode as dropdown. When I am running this project, in Select mode it is showing FNatureID instead of FNature and if I click to Edit the record it is displaying following error:
'lstNature' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value Do I have to give some If else condition that if FNatureID is .... then dropdown should display FNature.... If yes then what should be the code?

I'm using a DetailsView object to present a record from a database in table format. I'm actually using and ObjectSource object as the data source for the details view. In the object I am using as the source for the ObjectSource, I have paired properties that hold decimals. This is, I have a property called Year1 and another property called Year1Change. This for years 1 to six. The values from the Year1 properties are in a cell, whereas the change values are bound to texboxes. The code for the frontend is the following:
[Code]....
Now, as you can see in the tbYr2RtCh textbox, I have an OnTextChanged property to call an event handler. This is because I want to do two things when the text changes. The first one is to make the font in the textbox bold if the value it holds is different from the Year2 property. The second one is to change the text on tbYr2RevCh to adjust the revenue for the percentage increase in the rate. The problem I have is that I cannot access the object that is the source for the data and make those changes directly in the object, instead of having to update the database. I don't want to update the database until the client says so, but the changes should be calculated immediately. I thought about creating an method in the object that I could specify in the ObjectDataSource as the update method, but I'm still not sure how to go about it.

I 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.
