Web Forms :: GridView Delete Parameter Doesn't Delete Record
Jan 27, 2011
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).
I created a ListView and attempted to delete a record using the delete button and native procedures. It failed and threw an error.Pass in a valid dictionary for delete or change your mode to OverwriteChangesIn researching this issue, it appeared there is a problem with the list view when deleteing and ConflictDetection is set to
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.
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 connected to my objectdatasource, i wrote a class for the database queries.Now when i do an update of record i get the id form the grid, when i click on delete i don't get the id, its 0.Is there an option to set the id? i can't find it in the gridview.
First of all, when using the GridView control with Delete enabled, when I delete a record is the event handler in the code behind file handled before the record is deleted or after? I need to obtain a counter value that I have set up in the record before it is deleted so that I can decrement all of the counter values that followed it. Is the best way to do this to open a connection in the Delete even handler and take care of it by code, or is there another way to access a column value from the GridView control that would simplify the process?
I have 3 gridviews in one of my web page. I have simplified the system structure in the image below(further description will be stated below the image): As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews. During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
The data in the returned datatable will be filetered by type using RowFilter method and stored into the 3 dataviews. Each dataview will act as the datasource for the 3 GridViews respectively, and therefore I specified the datasource programatically instead of setting the datasourceid for each gridview.
However, the Update(command button) and Delete(template field) doesn't work, the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource. I couldn't figure out why, hope that someone who have come across the same problem couldn't provide some guidance.
I have a Gridview (VS2008 3.5) which has a Edit Button and a Delete button.he Delete button deletes the row without confirming deletion with the user first. ow can I use the Confirm/Delete Confirm from Ajax Toolkitif possible and if not, is there a way to Confirm/Delete with user firstwhen using Gridview?
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.
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.
