Forms Data Controls :: Delete Table Row Without Using GridView's DeleteCommand
Sep 6, 2010
I'd like to delete the row without using the DeleteCommand in GridView. I created the button "Obrisi" which should delete the row from the table, but when I click on it I get the following error: "The multi-part identifier "System.Web.UI.WebControls.DataControlFieldCell" could not be bound." and I don't understand what the problem is.
Here is the code (part of the code after else if is important):
How to write a delete query which can delete a specific row from grid view? I wrote this :
DeleteCommand="DELETE FROM member" It delete all my entry in table called member. =( <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FYPConnectionString %>" SelectCommand="SELECT * FROM [member]" DeleteCommand="DELETE FROM member"></asp:SqlDataSource>
GridView: grvResultPrimary Key: FLTIDTextBox: txtRemarksThere is a button named btnAdd in the FormView named FormView2.txtRemarks is outside the form.The scenario is that if user wants to add a record with empty textbox and click btnAdd then how to restrict user to add empty row to gridview?I have tried Validation by controling txtRemarks but it is not helpful for me because in the page there is a FormView1, FormView2 and grvResult.If I am applying validation then all other updation methods of FormView1 and grvResult are disturbing.Simple is that I want to give option to user that without empty data using txtRemarks, user can enter data to grvResult.
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 typically don't use the sqldatasource control but trying it out and can't seem to get the delete function working. It doesn't seem to be passing a parameter to my stored procedure. The error I get is: Procedure or function 'sp_DeleteCraigsListEntry' expects parameter '@craigslist_search_id', which was not supplied. Any thoughts?
Colour(Colour ID, Colour) DogColours(ColourID, Dog ID) Dog(Dog ID, Breed)
Colour ID and Dog are primary keys.
I have three web forms, one for each table. Dog colours consists of data that is already in the system from the other two tables. It basically joins a breed to a colour. My problem is this:
When i try delete a dog which is being used in dog colours the program crashes. How can i prevent this crash?
The second problem, the data source in the dog colours web form has the insert, update and delete tick boxes greyed out in the 'configure the select statement' so i am unable to delete a colour and dog joined together. how can i delete something in the dog colours?

I have a gridview control on my page that lists records and sorts them according to the most recent to the oldest record. The most recent record is first record at index 0, and I want the users to be able to only delete the first record in Gridview. Is this at all possible? I'd like there to be the word 'Delete' next to the first record only.
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?

iam insert data through gridview using datable, and i have 2button , insert and delete button , i wants to delete a row from the gridview using delete button below the code i constructed for insert, how to delete the row.
I added a Gridview to my page and added a new item a delete button, now when i push that button there is an error... Do I need to add some code for it? And yes, can you give an example?
