How can i remove an error of gridview which indicate that " the selected property can't be set declaratively.

I tried to put a ListView onto a webform but got an error right after that:
Error Creating Control - ListView1
The 'CssClass' property cannot be set declaratively.
BTW, does ListView support horizontal/vertical scroll bar? As I might have about 50 records in maximum, so need to have horizontal and vertical scroll bars. But do not need paging.
I've been binding dropdownlists within detailsview controls like so for years
SelectedValue='<% Bind("Field1")%>'
Now in VS 2008 is kicks out the error in the subject line. So what gives? And how do we bind dropdownlists then?
I have created a javascript to show hover colour and selected row in different colour in a gridview but when i select another row the previous row also still in the same selected row colour how to remove that.

I know that you can use exclamation sign to bind array of simple types (like string) to GridView like this
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Array Field" DataField="!" />
</Columns>
</asp:GridView>
But this doesn't seem to be the case with DataNavigateUrlFields
<asp:HyperLinkField DataNavigateUrlFields="!" DataNavigateUrlFormatString="RoleInformation.aspx?role={0}" Text="Manage users" />
and I get following error:A field or property with the name '!' was not found on the selected data source.

I've noticed that on aspx page IntelliSense doesn't display the Style property of a web control, even thought the control does have a Style property. Does that mean we shouldn't declaratively set the Style property:
<asp:TextBox ID="UserName" Style="color:Green; padding:0px; margin:0px;" runat="server"></asp:TextBox>

View 2 RepliesI'm attempting to load a GridView dynamically on a button is pressed.The gridview has AutoGenerateColumns="True" (set in skin definition) and has a declarative column definitions as follows:
<asp:GridView runat="server"
SkinID="GridViewDetail" ID="gvReport"
DataKeyNames="dateofcompletion">
<Columns>
[code]...
This all works fine the first time, but as soon as I select a different ddlCampaign item, it throws the"A field or property with the name 'FieldName' was not found on the selected data source" ERRORI kinda understand that it has retained the column mappings from the previous datasource assignment/binding and because the new datasource has different column headings it is throwing the error. What I can't seem to achieve is a clear or reset of defined gridview columns before adding the new columns. I cannot clear all columns because part of the GV defn is declarative.e.g.
gvReport.Columns.Clear();
gvReport.AutoGenerateColumns = true;
I have also tried clearing the previously added columns before new assignment/binding but it gives the same error.e.g.
for (int i = 2; i < gvReport.Columns.Count; i++)
{
gvReport.Columns.RemoveAt(i);
}
I am trying to bind the XML data to a datagrid from an XML file. I don't know why I am getting the message: "A field or property with the name 'User_x0020_Name' was not found on the selected data source."
The "User_x0020_Name" field does exist in the XML file. This is a portion of the XML file.

I have a web user control (ascx) that exposes an "ID" property. What I want to do is set this property when the SelectedIndexChanged event fires in a gridview in the containing page. However, I can't seem to do it.... Here's my code:
protected void grdPhysicians_SelectedIndexChanged(object sender, EventArgs e)
{
physicians_certif1.mdID = grdPhysicians.SelectedDataKey.ToString();
mvData.SetActiveView(viewEdit);
panAdditional.Visible = true;
}
Physicians_certif1 is the user control. It seems the user control is loading before the SelectedIndexChanged event has a chance to set it's property.

I need to remove certian rows from the Gridview so that certian users can't see certian rows. I have a row databoud event that checks for certian fields in the row and disables the entire row based on the value of those fields. However, it dosen't work well because if my gridview has 20 or 30 rows I have paging so if it disables all but 2 rows the user has to click in the pages of the entire gridview until they reach that row.
