I have a DetailsView control with DefaultMode = ReadOnly in my page. When the page loads, it shows the edit link. I would like to programmatically hide the edit link when the user is an administrator on page load. By default, I have set ShowEditButton="True". How do i reference the edit link when it is automatically genereated from the CommandField.

How to edit detailsview and gridview programitically?
I am binding data from the database to the detailsview/gridview dynamically with edit link .
Now when i click edit link i want to grab the selected row id and pass it as querystring or something like that to another page.
I am using c#,sql server and dataadapter to acomplish this.
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 am trying to programmatically set some lables inside a DetailsView that is populated by an ObjectDataSource. The detailsview is handled in an unusual way with one TemplateField that has one ItemTemplate that has one table that has two rows of significance and a boatload of bound items. I'll be working on the EditTemplate next. But now I need to set the top row lable values programmatically baised on the type of data that comes-up. I have scoured the Internet looking for ideas and found two possible approaches - neither worked. I get the error about something not being set to an instance of the object - or something like that.
Here is the ObjectDataSource:

My first approach was to set the OnSelected property to the following code in the code behind, which executes:

My second approach was to delete that OnSelected property and try the following code in the code behind:

I have a detailsview control linked to a SQL DB. I have created a template field with various controls within. When I click on edit and change the values and press update. The detailsview control changes back to read only and displays the original values. I have attached the code for the control and datasource below.

Detailsview edit not saving
View 3 RepliesI have already google the question, but couldn't found any relevant post.1) I want to make gridview's one column () editable according to some boolean value (flag). If flag is true when the edit is clicked, related column would be editable (text field), otherwise related column would be label.2) Same again, I want to make enable delete button in some rows and not some rows according to that flag.
View 1 Repliesi 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 have created two dropdown lists. The 2nd DDL depends for values on the 1st DDL. I have written code on the SelectedIndexChanged event of 1st DDL to change values of 2nd DDL. also i have used detailsview. In the template field i have used 2 DDL mentioned above. they are having SelectedValue='<%# Bind("") %>' property. Everything works fine but when i tried to edit record in detailsview & select value from 1st DDL then it gives me following error.
Server Error in '/' Application. Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I have a table that has previous data in it.
I have written a new site around this data
On occation a user will attempt to edit a record in a detailsview and they get this error:
System.ArgumentOutOfRangeException ddlState has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
This happens to be a list of states.
Is there way to allow the edit so the user can select a valid state from the list?
i have a gridview and a detailsview on my page.in gridview i have a EDIT Linkbutton - onclick i am displaying a Panel (with ModalExtender) within DetailsView (DefaultMode = readOnly).How can i change the mode of detailsview to EDIT (in code behind) when displaying in Modal.
I also have a Button NEW where i want to display the Detailsview (modal ) in Insert Mode.
I am trying to handle the detailsview programmatically but I don't know what I am doing wrong. My details view control isn't going into edit mode. My code for my gridview's select button properly loads the data into the detailsview but once the detailsview renders clicking on "Edit" doesn't switch the detailsview contol into edit mode.
This code draws the information from my database and loads the information into the dataview:

I have a webform with two gridviews; a textbox for the invoice number, and a button to kick everything into action. I programmatically handle the select statements in the VB.Net file because I need to iterate through the second gridview's table to perform calculations and then put those results into the first gridview's table. Then I bind them. It works just fine.
The first gridview has one row with the payment information. The second gridview has multiple rows with the items that the payment is handling.Now I need to handle the edit, update and cancel functionality. I tried using a sqlDataSource for edit, update and cancel because it is simple, but it requires a Select statement so I guess that idea is not going to happen. I put a commandField with showeditfield=true, but clicking edit gives an error that rowEdit isn't handled. I have put that sub gvInvoice_RowEditing in there, but being new at this I have no idea what to put into that sub.
I can programmatically create all that functionality in the code behind. Won't it be quicker and easier if I write sub's for Edit, Update and Cancel that tell the gridview what to do - trick it to automatically handle all that? Is there an example available demonstrating how to tell the gridview to go into edit mode and proceed as if it was using a sqlDataSource?As a final note: perhaps it would be simpler if I create a third gridview to handle the job of totaling all the cash and listing each check seperately.Here is my code. It probably isn't the most elegant approach, but it works.

I have a SQL DB with just 2 fields, ID and TEXT.What i was trying to do, was placing a Detailsview in EDIT MODE, then selecting from the DB like SELEC TOP 1 Text FROM DB.Then i placed a Ajax HTML Editor in the template field.How can i, keep the HTML Editor on the page, and use it for INSERT and/OR EDITING ?e.g.: on the first time the user opens the site management page, it will be blank, so it will show the HTML with no text on it. but the bottom button will be UPDATE and CANCEL. So when he enters the TEXT he clicks on UPDATE.

I have a Gridview that is filtered by a DropDownList.
A sales rep can select all prospects or filter on the first letter of the company name.
They can also sort the complete list or filtered by sales rep name.
There are several reps in the list
It was requested that once the list is filtered by the first letter of the name
and sorted by the sales rep, that once they select a customer to edit in the DetailslView, and that
edit is completed by closing the detailsview, they return to the same sorted list. they return
to the same filtered list but the sort is back to the default which is the company name.
Here's what is in the code behind file.
protected void Page_Load(object sender, EventArgs e)

I have used this before with no issues. Now I get to the page with the detailsview using parms I pass with the key to the row. When the page opens the row I want to update is displayed.
I am having 2 issues. One when I change any of the fields and hit Update (the Edit button),
all rows are updating not just the row displayed. The second problem is I have an update_date and an Updated_by field with code in code behind in the Onitemupdating event and they are not updating at all. (This bit of code works fine in another page I have to updated similar fields on an insert).
How can one disable a Link Button in gridview. In gridview, I had defined linkbutton as :

</ItemTemplate>
</asp:TemplateField>
Is there a way based on the current user that when the page loads that the Delete option on the gridview is disabled?
