Hi,

I am using a GridView, no sql or objectdatasource. In the rowdeleting
event, the event arg e.Values.Count = 0, and the sender.Rows = 0, yet I have
3 rows and multiple non-key datavalues. Why would these values be 0?

thanks for any help,
Marianne

event code:
protected void CoBrandsGrid_RowDeleting(object sender,
GridViewDeleteEventArgs e)
{

// Delete the row in the database

int cobrandID =
Convert.ToInt32(CoBrandsGrid.DataKeys[(int)e.RowIndex].Value);

string description = e.Values["Description"].ToString();

//string description = CoBrandsGrid.Rows[e.RowIndex].Cells[0].Text;

CobrandData.DeleteCobrand(cobrandID, description);

CoBrandsGrid.DataSource = CobrandData.LoadCobrands();

CoBrandsGrid.DataBind();

}

aspx code:
<asp:GridView

id="CoBrandsGrid"

autogeneratecolumns="False"

backcolor="White"

bordercolor="Transparent"

width="80%"

gridlines="None"

cellpadding="4"

cellspacing="2"

borderstyle="None"

DataKeyNames="CoBrandID"

EmptyDataText="No Cobrands have been created."

AlternatingRowStyle-BackColor="#E0E0E0"

OnRowDataBound="CoBrandsGrid_RowDataBound"

OnRowDeleting="CoBrandsGrid_RowDeleting"

EnableViewState="false"

runat="server" >

<headerstyle font-bold="True" horizontalalign="Center" forecolor="White"
cssclass="tableHeaderStyle"

backcolor="#660000"></headerstyle>

<footerstyle forecolor="Black" backcolor="#C6C3C6"></footerstyle>

<columns>

<asp:boundfield itemstyle-horizontalalign="Left" datafield="Description"
headertext="CoBrand Description"></asp:boundfield>

<asp:boundfield itemstyle-horizontalalign="Left" datafield="EnterDate"
headertext="Created Date"
dataformatstring="{0:MM/dd/yyyy}"></asp:boundfield>

<asp:boundfield itemstyle-horizontalalign="Center"
datafield=""></asp:boundfield>

<asp:boundfield itemstyle-horizontalalign="Center"
datafield=""></asp:boundfield>

<asp:CommandField

ButtonType="Link"

DeleteText="Delete"

ShowDeleteButton="true"

ControlStyle-CssClass="removeButton"

ItemStyle-HorizontalAlign="Right"

/>

</columns>

</asp:GridView>

hi,

the reason e.Values.Count = 0 (and e.Keys.Count = 0 as well) is that you are
not using a datasource object to bind to the grid.
When you use the traditional databinding method of calling DataBind()
method, GridViewDeleteEventArgs.Values and GridViewDeleteEventArgs.Keys are
not populated.

you need to access these values using the row index.

hope this is useful.
