Hello,
I am developing with VS.Net 2003 on the asp 1.1 platform.
I am a few days new to using a datagrid. I found a nice tutorial and had no
problems using an editable datagrid with textboxes and an additional
buttoncolumn where I used a delete button to delete a specific row.
Once I had finished that, I trnsformed the grid tso it will display a
dropdownlist indtead of a textbox. After much grappling, I pretty much have
it working except for one detail. Now, the delete function will not work
properly.
Following is the declaration of the grid in the .aspx page:
<asp:datagrid id=DGR_List runat="server" cellpadding="3"
oneditcommand=" DGR_List_Edit" oncancelcommand ="DGR_List_Canc el"
onupdatecommand ="DGR_List_Upda te" onitemcommand=" DGR_List_Comman d"
onitemdatabound ="DGR_List_Item DataBound" autogeneratecol umns="false">
<edititemstyl e forecolor="Maro on"></EditItemStyle>
<alternatingite mstyle backcolor="#B8C 6D4"></AlternatingItem Style>
<headerstyle font-bold="True" forecolor="Whit e"
backcolor="#336 598"></HeaderStyle>
<columns>
<asp:TemplateCo lumn HeaderText="Acc ounts">
<itemtemplate >
<asp:label id=Label4 runat="server" text='<%#
DataBinder.Eval (Container, "DataItem.Accou nt") %>'><!--use container because
the DGR is bound to the conatiner--></asp:label>
</ItemTemplate>
<edititemtempla te>
<!--this is a different data source...not what the dgr is bound
to-->
<asp:dropdownli st onselectedindex changed="Change _Cust_TB"
id=DropDownList 1 runat="server"
DataSource="<%# bizObj.Get_IB_A ccounts(IB_Acct )%>" DataTextField=" Account"
DataValueField= "Account" Width="100px" autopostback="T rue">
</asp:dropdownlis t>
</EditItemTemplat e>
</asp:TemplateCol umn>
<asp:BoundColum n DataField="Valu e" ReadOnly="True"
HeaderText="Val ue"></asp:BoundColumn >
<asp:BoundColum n DataField="Unit " ReadOnly="True"
HeaderText="Uni ts"></asp:BoundColumn >
<asp:EditComman dColumn ButtonType="Lin kButton" UpdateText="Upd ate"
HeaderText="Edi t Acct" CancelText="Can cel" EditText="Edit" >
<headerstyle wrap="False"></HeaderStyle>
<itemstyle wrap="False"></ItemStyle>
</asp:EditCommand Column>
<asp:ButtonColu mn Text="Delete" HeaderText="Del ete Acct"
CommandName="De lete">
<headerstyle wrap="False"></HeaderStyle>
<itemstyle wrap="False"></ItemStyle>
</asp:ButtonColum n>
</Columns>
</asp:datagrid>
When the Delete button is clicked, the onitemcommand event fires and
DGR_List_Comman d is called:
public void DGR_List_Comman d(Object sender, DataGridCommand EventArgs e)
{
switch(((LinkBu tton)e.CommandS ource).CommandN ame)
{
case "Delete":
Delete_Acct(e);
break;
default:
//do nothing
break;
}
}
And the function calls Delete_Acct(e):
public void Delete_Acct(Dat aGridCommandEve ntArgs e)
{
// e.Item is the table row where the command is raised. For bound
// columns, the value is stored in the Text property of a TableCell.
TableCell itemCell = e.Item.Cells[0];
string strCurrentAcct= itemCell.Text;
//call my own function to dlete item in first cell
bizObj.Delete_A cct(strListName , strCurrentAcct) ;
//do some more stuff and reload grid
