SelectedItem backcolor

[tman24m]

Hey all,

I'm trying to get the selected item (only the selected item) to have a backcolor of cyan. However, the problem is that I can't use the commandname="Select" method because I've already assigned the commandname property to another command. Here's the code:

<asp:datagrid id=&quot;dgMMCTRN3&quot; style=&quot;Z-INDEX: 101; LEFT: 15px; POSITION: absolute; TOP: 27px&quot; runat=&quot;server&quot; AutoGenerateColumns=&quot;False&quot; GridLines=&quot;None&quot; Height=&quot;73px&quot; Width=&quot;219px&quot; OnItemCommand=&quot;dg_ItemCommand&quot; DataKeyField=&quot;ID&quot; OnItemDataBound=&quot;dtgMMCTRN3_ItemDataBound&quot; ShowFooter=&quot;True&quot;>
<SelectedItemStyle Font-Bold=&quot;True&quot; BackColor=&quot;#FF8080&quot;></SelectedItemStyle>
<AlternatingItemStyle BackColor=&quot;AliceBlue&quot;></AlternatingItemStyle>
<HeaderStyle Font-Bold=&quot;True&quot; BackColor=&quot;SkyBlue&quot;></HeaderStyle>
<Columns>
<asp:TemplateColumn>
<HeaderTemplate>
<u>Link</u>
</HeaderTemplate>
<ItemTemplate>
<asp:LinkButton ID=&quot;lb1&quot; CommandName=&quot;doProds&quot; Runat=&quot;server&quot; Text='<%# Container.DataItem(&quot;MCCSUM&quot %>'>
</asp:LinkButton>
</ItemTemplate>
</asp:TemplateColumn>
<asp:ButtonColumn CommandName=&quot;Select&quot; DataTextField=&quot;MCCTYP&quot; HeaderText=&quot;Typ&quot; HeaderStyle-Font-Underline=&quot;True&quot;></asp:ButtonColumn>




AND THE CODE BEHIND IS:

Sub dg_ItemCommand(ByVal sender As Object, ByVal e As DataGridCommandEventArgs)
Dim mo, trn As Double
Dim acct As String
mo = CDbl(Request.QueryString(&quot;postDat&quot)
trn = CDbl(Session(&quot;LastPost&quot)
acct = Request.QueryString(&quot;acct&quot

If e.CommandName = &quot;doProds&quot; Then
sProduct = CType(e.Item.FindControl(&quot;lb1&quot, LinkButton).Text
Dim intID As String = dgMMCTRN3.DataKeys(e.Item.ItemIndex)

Dim strSQLDet As String
strSQLDet = &quot;select MCNRRN, MCCSUM, MCCTYP, MCCTRN, MCAJE, MCFDPT, MCFDBT, MCFCRD, CONCAT(CHAR(MCCSUM),CONCAT(MCCTYP,MCCTRN)) AS ID &quot; & _
&quot;from P12582.MMCTRN3 &quot; & _
&quot;where MCFDBT = '&quot; & acct & &quot;' AND MCDGLM = &quot; & mo & &quot; AND MCDTRN = &quot; & trn & &quot; AND CONCAT(CHAR(MCCSUM),CONCAT(MCCTYP,MCCTRN)) ='&quot; & dgMMCTRN3.DataKeys(e.Item.ItemIndex) & &quot;' AND MCFPAG = '1' &quot; & _
&quot;or MCFCRD = '&quot; & acct & &quot;' AND MCDGLM = &quot; & mo & &quot; AND MCDTRN = &quot; & trn & &quot; AND CONCAT(CHAR(MCCSUM),CONCAT(MCCTYP,MCCTRN)) ='&quot; & dgMMCTRN3.DataKeys(e.Item.ItemIndex) & &quot;' AND MCFPAG = '1' &quot;
Dim dr As OleDbDataReader
dr = GetDataReader(strSQLDet)

e.Item.BackColor = Color.Red
dgDetails.DataSource = dr
dgDetails.DataBind()
dr.Close()
End If
End Sub



The item changes to red, but then when another item is selected, the first item retains the backcolor of red

There's got to be a better way to do this, but all I can think about now is this (C#): add this loop inside the dg_ItemCommand, instead of e.Item.BackColor = Color.Red line.

foreach(DataGridItem dgItem in dgMMCTRN3.Items)
{
if(dgItem.ItemIndex == e.Item.ItemIndex)
{
dgItem.BackColor = Color.Red;
}
else
{
dgItem.BackColor = Color.White // or whatever default color is
}
}

This will probably achive your goal and highlight the selected row, but like I said, there must be a better way of doing this.

thanks for the post.

i added this and still no worky

Dim dgItem As DataGridItem
For Each dgItem In dgMMCTRN3.Items
If dgItem.ItemIndex = e.Item.ItemIndex Then
e.Item.BackColor = Color.Cyan
ElseIf dgItem.ItemIndex <> e.Item.ItemIndex Then
If e.Item.ItemType = ListItemType.Item Then
e.Item.BackColor = Color.White
ElseIf e.Item.ItemType = ListItemType.AlternatingItem Then
e.Item.BackColor = Color.AliceBlue
End If
End If
Next

When you pick the autoformat builder, it assigns a color to the selected property, does it not???

Try taking a blank form, slap a grid on it, and see how it sets the color.
I'm not trying to be smart, it's just what I would try.

I want to do a tutorial when I am done this project titled &quot;How to make your Datagrid behave&quot; LOL

My grid wants to grow in the Y direction.

thanks for the post. with the autobuilder, it only assigns the color if you set the commandname property to = &quot;Select&quot;. Problem is, I'm already using the commandname property for something else. Anyway, I just figured it out. I was hasty with my last post. Didn't realize that after I was setting the backcolor of the selected item I was resetting based on whether or not it was an item or alternating item. I moved the selected item down later in the code and now it works fine

Dim dgItem As DataGridItem
For Each dgItem In dgMMCTRN3.Items
If dgItem.ItemIndex <> e.Item.ItemIndex Then
If e.Item.ItemType = ListItemType.Item Then
e.Item.BackColor = Color.White
ElseIf e.Item.ItemType = ListItemType.AlternatingItem Then
e.Item.BackColor = Color.AliceBlue
End If
End If
Next
e.Item.BackColor = Color.Cyan
