C# - How To Delete A GridView Row
Dec 10, 2010
I have this code until now:
<asp:TemplateField ShowHeader="False" ItemStyle-Width="150px" HeaderStyle-BackColor="#003ca1" HeaderStyle-ForeColor="white">
<ItemTemplate>
<asp:LinkButton ID="linkDelete" runat="server" CausesValidation="False" CommandName="Delete" OnClientClick='return confirm("Diesen Eintrag wirklich löschen?");' Text="Löschen" />
</ItemTemplate>
</asp:TemplateField>
At this moment, the GridView deletes the row physically.I want to catch this in CodeBehind, cancel the delete-operation and want only set a "IsDeleted"-Flag in the database.

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 table with primary key whose importance is technically high and none business wise. So, when I display the table data to user, I would like not to show him the primary key. Even if I load it in sqldatasource and dont show (I did this by removing the cloumn in "Columns" tag of GridView), I am not able to update or delete row using the built-in UpdateCommand & DeleteCommand. I have created the delete paramters but it does nothing when I hit the delete button.How to get around it?

I created a GridView that uses a custom paging method that allows for alphabetical paging. I seem to be having some problems now rebinding the GridView after a delete occurs. The row is deleted, it's just that the rebinding doesn't happen so to the user it looks like the delete failed. Been over and over my code and can't understand why. See the final block which is supposed to fire on the GridView1_ItemDeleted event.

I have one GridView and one "Add" Button. If I click the "Add" button, one new row will be added to the GridView at the sametime I want to show "Update and Cancel" buttons in CommandField Column.
When I click the Update Button after the Insertion of the New Row, I want to Show the Delete Button in the Command Field Column. Once again When I click the Delete Button, the Corresponding row will have to be deleted.
So far I have done all the four things(update, cancel, edit and delete) at the same. But now I dont want Edit. The problem is when I include "ShowDeleteButton = True" in the command field, the "update and cancel" buttons are not displaying when I click the "Add" button.The "update cancel" buttons are displaying only when I include "ShowEditButton = true". But I dont want to Edit the Column.
Here I want only to do Update, Cancel and Delete. How to do? I dont want coding, I have written all the coding parts in Gridview_Rowupdating and RowDeleting Event.

How can I customize automatically generated command button, e.g. Delete?
I want to add a client confirmation on deleting and in the same moment I want this button would be generated on setting AutoGenerateDeleteButton="true". Is it possible??
I can add a custom button this way:
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton runat="server" CommandName="Delete" OnClientClick="return confirm('Delete?')">Delete</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
but it will be not automatically localized and will be not generated on setting AutoGenerateDeleteButton="true"!

I am interested in building an intranet document management system to be used from Internet Explorer using ASP.net, VB.net, and MS SQL Server but have no experience in doing a project like this. Supported file types would be txt, pdf (from scanner or imported from file system), or jpg. What concepts I should look at researching/learning about to build the system in a way that files will be stored as small as possible, retrieved and displayed quickly, and secured. The users would be spread out over a regional area covering 4 states.

I have a grid contol that allows delete what I would like to have is someway to say Are you sure you want to delete?I found this code online, and tried it but it did not work, Do I need something more some behind code maybe?Here is what I found online:Adding 'Delete Protection' to controls If you use a control set up to allow Delete, the Delete button gives a straight delete without any warning, which can be dangerous.To give a warning dialog box, add an OnClientClick event to the Delete button, as follows.
<asp:LinkButton
ID="DeleteButton"
runat="server" CausesValidation="False"
CommandName="Delete"
OnClientClick="return confirm('Are you sure you want to delete this record?');"
Text="Delete">
</asp:LinkButton>
Here is my code: You can see where I added the code from above.
<ItemTemplate>
ID:<asp:label id="IDLabel" runat="server" Text='<%# Eval("ID") %>' /><br />
Name:<asp:label id="NameLabel" runat="server" Text='<%# Bind("Name") %>' /><br />
Destination:<asp:label id="DestinationLabel" runat="server" Text='<%# Bind("Destination") %>' /><br />
OutDate:<asp:label id="OutDateLabel" runat="server" Text='<%# Bind("OutDate") %>' /><br />
ReturnDate:<asp:label id="ReturnDateLabel" runat="server" Text='<%# Bind("ReturnDate") %>' /><br />
LeaveTime:<asp:label id="LeaveTimeLabel" runat="server" Text='<%# Bind("LeaveTime") %>' /><br />
ReturnTime:<asp:label id="ReturnTimeLabel" runat="server" Text='<%# Bind("ReturnTime") %>' /><br />
ContactNumber:<asp:label id="ContactNumberLabel" runat="server" Text='<%# Bind("ContactNumber") %>' />
<asp:linkbutton id="EditButton" runat="server" CausesValidation="False" CommandName="Edit" Text="Edit" />
<asp:linkbutton id="DeleteButton" runat="server" CausesValidation="False" CommandName="Delete" OnClientClick="return confirm('Are you sure you want to delete this record?');" Text="Delete" />
<asp:linkbutton id="NewButton" runat="server" CausesValidation="False" CommandName="New" Text="New" />
