Forms Data Controls :: GridView And DetailsView Delete Feature?
Feb 15, 2011
currently have a page that I use to allow users to edit information for their attending group. They can edit names, sex, tshirt sizes etc. All they have to do is selsct their club from the gridview and the details are bound to the detailsview. They edit then click submit. What I now want to accomplish is a similar page that deletes members. I know gridviews come with a delete button you can enable, but I need it to fit in with my custom code-behind. I want users to select the member they want to remove from their registration, that persons details to pop up as text in the details view positioned below the gridview (as text, not as text boxes), ask them to confirm the delete by clicking the delete button in the detailsview. I'm really not proficient at VB or ASP.Net, I just got thrust into this project, so any help would be amazing. I'd like to know how the thing works though. Below is the code I use for the editing.

I have both a details view and gridview with deleting enabled. I'm concerned about users accidentally clicking delete, and poof, the record is gone. Is there a setting to get a confirmation message before the delete is actually done?

I am using the multiview which on one view has my gridivew and the other has my detailsview. My gridview is a template gridview and I have a button for edit and another for delete.What I want to do is when either the user clicks the edit or delete buttons that the appropriate record is selected and the multiview view is changed to the detailsview showing the selected record.My datasource is microsoft's object container datasource NOT the objectdatasource and I am using model view and controller design pattern in my coding.

I am using VS 2008 SP1. My also have included CSS Friendly adapter [URL] in my project ( I mentioned this because my GridView Empty data template is not showing when using GridView's CCS Friendly adapter). I have a GridView and a DetailsView. When a record in GridView is selected its details information is shown in the Details View. Type of Data source I am using is ObjectDataSource. My Insert and Update methods works perfectly. It is only the Delete method that is passing null values to the underlying object delete method. My source codes for both the UI, BLL, DAL is shown below

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.

CellPadding="4" ForeColor="#333333" Width="400px" Font-Size="9pt" [code].....

In my Admin page, I have a drop down list containing all current user tables in the database. The user chooses one.
My DetailsView below uses that parameter to populate itself with data from that table. The stored procedure used to select the data passes a string to sp_executesql. The string is concatenated from a select statement and the tablename parameter. Can I do something similar for Update/Delete statements? I'm not sure of the best approach, given that I won't know which/how many fields will be in the DetailsView at runtime, and which of these are keys - the choice of table depends on the user. I think Insert will be straightforward - am I right? I would like to streamline things as far as possible. Is it possible to dynamically pass in the values in, say, a string, and get my stored procedure to understand them? And what's the best method of grabbing the values from the DetailsView in this situation?

Here is a snapshot of my gridview with selection enabled. How can I modify this, so instead of having an extra row that says select, I could have the order numbers be selected (hence the order numbers would all be underlined)

How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?

Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="photoID"

I am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
Assembly="Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c" %>
and I added this as a Gridview column:
<SharePoint:DeleteItemButton
runat="server"
ID="CustomFormDeleteItemButton"
ControlMode="Edit"
/>
and this is the error I get:
An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.

I 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.

I 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 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.

I've got a Gridview which has a datasource to a particular database.
I've got a DetailsView which has a datasource to a table in another database.
when I select a Gridview row, I need to populate a field in the DetailsView with the Primary Key field (showing in the Gridview) from the Gridview.
Can this be done (if so, how?)?
Also (but not as important) :
If there's no field related in the second table, I'd like it to come up in Insert Mode - if there is a field related, I need it to come up in Edit mode

I am using a GridView and a DetailsView to establish a master to detail form, the idea is to let user select a record on Gridview and Detailsview will load selected record for editing. Here is declaration for the ODS and Detailsview.
[Code]....
this is working fine when I select a record from GridView and edit/update it in DetailsView. But it's not working so well when I insert a new record using DetailsView, because after insertion the selected record remains as the record selected in GridView.

I have a gridview with a select button. There are 181 records in the gridview all coming from the same database table. When I select the first 5 rows the details view comes up, but after that it doesn't show... The information that it is pulling is the same for the first 5 rows as the other 176 rows. Why won't it show the detailsview?!
