View 1 RepliesI'm using Dynamic Data and LINQ to SQL for some admin pages on a .NET 3.5 web app. All my admin tables have a CreatedBy, CreatedDate, UpdatedBy, and UpdatedDate.I'm looking for a way to inject the setting of these properties before the objects are inserted and updated.
I've seen an object_inserting hook if you have a linq to sql datasource in the web form, but I'm using dynamic data...is there an easy way to generically set that? And I've also looked at modifying each of the partial classes for my admin objects, but the closest hook I see is to implement the OnValidate method with the Insert action.
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'.

View 1 RepliesI have a gridview with linq and in the itemtemplate I have a column like this :
Bind("SUPERFICIE","{0:N00}")
If I display my gridview, I have this kind of value : 6'555
When I delete this row I have this error :
Failed to define one or more properties of type DS.MY_TABLE 6'555 is not a valid value for Decimal.
Apparently, when I use a format on bind, it change my values in my ds and I cannot delete my row!
I don't understand, because in my logic with the bind format I don't need to correct some formats for delete a row !
Insert Edit Update Delete (CRUD) in GridView using MySQL Database?
View 1 RepliesI have a gridview that displays data from my online database. Works great. edit/update/delete functions work also.
I decided to import data into my database through my SQL Server web admin. It worked fine, and the imported data now shows up in my gridview, but once I decide to use my gridview edit/delete buttons, the grid won't update the data or delete the rows. It will however properly function on the rows that were manually entered with the gridview and/or in visual studio.

View 1 RepliesHow 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.

I can open the modalpopup, can close the popup, but if i click the "edit" button to edit any of rows, the popup closes automatically. If I click again, the "Update" and "Cancel" buttons shows, and after clicking one of those, popup closes again. The above code works, if i use gridview the insert, edit or delete the data, does not close automatically. What may be the cause of this problem.

View 1 RepliesHow do I clear my formview after a record has been inserted or deleted? At the moment it just sits in the previous state with the same details in the fields, still with the Insert button. Either it would be good to drop the formview altogether (I have a grid view on the same page) or move into the edit mode for the just inserted record.
Also the same with the delete - the formview stays on screen with the deleted record details and the delete button still available - I know it has fired though as my gridview is updated.
