I Have a gridview with a command button for delete defined.

On the Datasource for the grid I have a DeleteCommand that runs a stored procedure that takes theID field defined in grid view control.

When the delete command is selected in the gridview the deletecommand stored procedure is called twice with the same ID (I have traced this).

I have removed all delete eventsfrom the gridview and datasource.

I have a FormView that has a selectcommand using the GridViews primary ID.

I have autoeventwireup set to true.

There is no code being ran before or after deletion.

I did have a refresh procedure being ran after delete. When this was active Instead of the same record being deleted twice, the selected record and the record below in the grid were both being deleted with one call.

Any Ideas?

for anybody interested there's a workaround for this problem: insert the following lines in your RowCommand event:

if (Request["x"] == null || Request["y"] == null)
{
Response.End();
}

Here is my work around, that seems to work nicely. If you use a TemplateField and an ImageButton, you do NOT have to handle the button event.

The GridView sees the CommandName=Delete and handles it:

<asp:TemplateField >
<ItemTemplate>
<asp:ImageButton

id="DeleteButton"
CommandName="Delete"

ImageUrl="~/images/delete.ico" runat="server" />
</ItemTemplate>
</asp:TemplateField>

That's all, no double postback, no custom event handling of the delete. It would be nice if the CommandField worked correctly though!

The delete button is a "delete" configuredCommandField in the GridView. In the ASP.NET application I have found the following to be true.

If I set the ButtonType to image and specify a deleteimage url for the "delete" command field then the Datasources DeleteCommand fires twice.

If I set the ButtonType to button for the "delete" CommandField then the datasources deletecommand is properly fired once.

I would like to display a delete image in the GridView.

Sorry, I thought it was about Windows Forms...

I have the same problem! When the delete CommandField type is "Image", Delete fires twice!

Has anyone figured out why this happens?

this seems to be a known (and serious) issue that makes the gridview practically useless. i have seen several posts all dealing with that same problem, some of them even dating from last year. unfortunately ms doesn't seem to care... at least i didn't find any solutions posted yet.

btw: it seems that the problem doesn't correspond with the delete button, but occurrs when setting buttontype=image (no matter what command).

i have already seen thatsolution somewhere, but unfortunately that does not work for me. the reason is that when using a template field you need to rebind the grid after the postback in order to get the events of the controls in the template fieldfired -and this is exactly what i'm trying to prevent because my grid is showing the results of a rather complex search and having to bind it twice (and therefore execute the search twice) significantly lowers the performance. using the gridview commands helps me a lot there because the rowcommands get fired without the need to rebind.

Same problem here! Tried too design my crm app a bit as a programming break to find out that design influences functionality, should be taken care of. After three days of guessing where I went wrong I changed as a last option my nice delete image to buttontype="button" and no way, you're kidding, it works totally fine now! But looks like...*.*

Yours sincerely!

This seems to have fixed my problem with it firing 2 times, however in my function, it's only firing "Select" command when I select on this button.  I'm thinking it could be because I have it setup to select entire row when click anywhere...but is there a middle ground where I can make it run delete command when that field is selected?

<asp:TemplateField > <ItemTemplate> <asp:ImageButton id="b_Delete" CommandName="Delete" ImageUrl="~/images/Ex.GIF" runat="server" /></ItemTemplate></asp:TemplateField>

protected void gv_Files_RowCommand(object sender, GridViewCommandEventArgs e)

if (e.CommandName == "Delete")

Hi,

Did you solve your problem? I just spent 3 days fixing similar problems with the gridview, this is the first time I use the edit feature of the GridView.

Like everyone, during these few days, I complain a lot about the product quality of microsft, how come they produce such a difficult control with BUGS reported every where, I thought.

As usual, at last, ( 3 days almost 24 hours of work and learning) I found that most of my (I don't know whether it is yours), is due to a databinding call made to the grid inside the Page_Load event handler - every time there is a post back, the grid is databind again, before calling the RowCommand, RowUpdate...

void Page_Load()

{

if (Page.IsPostback)

{

DataBindingCall(); // this causes a lot of trouble. This method with bind the gridview to a data source.

// After I remove this call, a lot of troubles are gone.

....

}

else

{

}

}

I hope my experience is useful to you or other gridview users.

I found the problem to be with the Grid HTML declaration itself.

I was under the impression that tohave my delete event handler (dgResults_DeleteCommand) execute when the DataGrid's DeleteCommand event firesI had to specify OnDeleteCommand="dgResults_DeleteCommand" in the DataGrid's declaration. This turns out to be wrong or at least removing it from the grid declaration stopped the delete event firing twiceâ€?which was causing me grief & anguish as my coding buddy left work on-time as I was still sitting there stumped!

Grid that fires the delete event procedure TWICE....

<asp:DataGrid
runat="server"
ID="dgResults"
BorderWidth=1px
AutoGenerateColumns="False"
Width="98%"
HorizontalAlign=Center
BackColor="AliceBlue"
AlternatingItemStyle-BackColor="Lavender"
AllowSorting=True
HeaderStyle-BackColor="#FFFFFF"
HeaderStyle-Font-Size="Small"
HeaderStyle-ForeColor="#003366"
ItemStyle-Font-Size="9pt"
OnDeleteCommand="dgResults_DeleteCommand"
OnItemDataBound="dgResults_ItemDataBound">
<Columns>
columns ..... </asp:DataGrid>

Grid that fires the delete event procedure ONLY ONCE....

<asp:DataGrid
runat="server"
ID="dgResults"
BorderWidth=1px
AutoGenerateColumns="False"
Width="98%"
HorizontalAlign=Center
BackColor="AliceBlue"
AlternatingItemStyle-BackColor="Lavender"
AllowSorting=True
HeaderStyle-BackColor="#FFFFFF"
HeaderStyle-Font-Size="Small"
HeaderStyle-ForeColor="#003366"
ItemStyle-Font-Size="9pt">
<Columns>
columns ..... </asp:DataGrid>

Also, the problem is also present in the DataGrid with all the events. This bug was introduced in asp.net 2.0 because in 1.1 this situation did not happen.

Change the Button Field as Link Button:

Button field as Link button and, in the text, set de tag of a html image
<img src="IMAGENAME" >
and the event fires one time

<asp:ButtonField Text="&lt;img src=Images/edit.gif /&gt;" HeaderText="Editar" >

</asp:ButtonField>

I just hope microsoft could fix this problem promptly.

I think that the event is bubbling up, firing for the image/button, and then the grid column.

You probably have to catch the image event and cancel the event from bubbling up to the grid.

How about this:

if (!Page.ClientScript.IsOnSubmitStatementRegistered(this.GetType(), "fixTwice")){

Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "fixTwiceVar", "var isSubmited = false;", true);

Page.ClientScript.RegisterOnSubmitStatement(this.GetType(), "fixTwice", "if(isSubmited){return false;}else{isSubmited = true};");

Hallo RCUELLO,

you are the greatest! It works fine!
