I have a list of properties in a gridview. I have a property ID column. I have a delete column. On clicking delete, after the delete event has been fired e.g. gridview_rowdeleted. I want to get the propertyID of the deleted column in order to set it to the session("propertyID") usage is the use that propertyID in another function to delete associated property Images.
View 5 RepliesHow to access gridview commandfield delete button on RowDataBound event? How the cells and controls in griview are accessed
View 2 RepliesI have a very simple page that consisist of an UpdatePanel that contains a gridview. The gridview includes a delete button for each row, which should fire the Delete event. But the event never fires. If I set a breakpoint inside the event handler, it never gets hit and the row does not get deleted. When I say OK on the confirm dialog it just goes back to the page. I tried taking out the confirm button extender
ASPX:[Code]....

all of a sudden my GridView has stopped firing the row update event. Friday I was working on it and was working flawlessly. Now I haven't made any changes to the code and all of a suddent has stopped working (yes rediculously bizarre and have been banging my head all day thinking what the something is wrong with it, excuse my french).
Everyone of those events fire except the update. I click the update button and nothing happens.
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 with edit and delete parameters enabled. When I click on the edit link, I can edit the record successfully. However when I click on the delete link, nothing happens (the record does not get deleted).

View 6 RepliesI have created a custom control which uploaded files to the server . These uploaded files list that is the name of the file and the file path i save in a session and the files i save to a temp directory .
Now, I want to delete these files as well as clear the session when this control is no longer used .How do i find whether the control is no longer used in the page . I should be doing this from the Custom control and not from the Page ?
In my application there are some GridView(GV) controls. Deletion is already implementd in GV's RowCommand.
Now GVs are bound to ObjectDataSource(ODS). So, whenever a deletion is performed I run into situation like
"System.NotSupportedException: Deleting is not supported by ObjectDataSource.........."
So, I have created a Delete method in the DAL that does nothing and hooked it up to the ODS via its DeleteMethod property.
My question is, is it possible to suppress the Delete event of the ODS? So, when something is deleted thru GV, it will be handled in the GV's RowCommand and ODS' Delete event handler is not called.
in the grdview i use
AutoGenerateDeleteButton="True"
and call OnRowDeleting= "GridView1_RowDeleting"
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)

Creating a list of users with a "Delete" linkbutton next to each". Seems I got it all wrong (again..away from webforms a long time).
Here's what I do:
Building a list of users with delete buttons:
Code:
foreach (var user in users)
{
var usr = user as UserInfo;
var row = new TableRow();
var cell = new TableCell();
[Code] ....
The "Delete""event handler:
Code:
protected void btnRemoveModUser_Click(object sender, EventArgs e)
{
var button = sender as LinkButton;
var userController = new UserController();
var user = userController.GetUser(PortalId, int.Parse(button.CommandArgument));
RemoveUserFromRole(Enums.KnowledgebaseRole.KB_Moderators, user);
}
I got a hunch though it's because of the when/where I'm loading that list of users. I call the function (getting a list of all users, clearing the table and populate it again):
In the page load, if not a postback.
Every time the "Add user" function have been called (that works fine).
Every time the "Delete user" function are called.
The last will not delete the user (still in database) but reload the ^&* form without any users.
I just found that the delete handler does not get called at all, but the button post back the form, so my list of user's don't get loaded.
protected void ListView1_ItemDeleting(object sender, ListViewDeleteEventArgs e) {
// ListViewItem item = ListView1.Items[e.ItemIndex];
ListViewItem itm = ListView1.Items[e.ItemIndex];
// ListViewItemType gd = ListView1.Rows[e.RowIndex];
//ListViewItem gd = ListView1.SelectedIndex ;

I have two gridview in a single webform, I need to fire one gridview RowDataBound event from another one gridview's RowCommand.
View 3 RepliesI 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.
