But fo you filter the product by title and then delete the product, if i try a rebind on the grid it fails as the selected value of the combo in the filter template no longer exists so it errors as follows:

Any ideas?

Hi Jon,

From what I understand you delete the item by which you filtered on each filtering, therefore I do not see why you set the SelectedValue at all, as this value will never exist. You should better add an empty node or an unbound one to the combo and set it as selected.

All the best,

Hi Tsvetina,

Thanks for your reply, i am not sure i follow and maybe i didn't explain it properly.

If i simply call the page up and the grid returns rows and i select one to delete the code:

Case "DeleteProduct"

ProductItems.Delete(e.CommandArgument)

RadGridProducts.MasterTableView.DataBind()

Works fine. But If i use the product title filter option and i filter so that the grid filters down only to show a single product and then I delete that product, the above code fails with the error I posted before. It may not be linked to the combo box but i wondered from looking at the error code that maybe it doesnt clear the selected item property of the radcombo on the rebind and then trys to find it but cant as the item has been deleted from the DB, the delete works fine.

does that make sense?

answered on 02 Sep 2011, 02:03 PM

Hi Jon,

It is in your markup that the combo looks to select this value:
SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("Product_Title").CurrentFilterValue %>'

If by deleting it from the grid datasource, you also delete it from the combo source (if they use and and the same table in the database), the combo cannot find it and may cause the exception.

Can you try removing the SelectedValue setting to confirm whether it causes the exception?

One other thing, if you are using a declarative datasource to bind the grid, do not call DataBind() in the code behind for rebinding the grid, use Rebind() instead.

Kind regards,

I have run into a similar situation. I searched for a solution and came across this. In my filter Combo I am using a separate datasource from the main grid. If I try to remove the SelectedValue the delete will work but the filter will not after selecting an item. It will not Select All because the OnClientSelectedIndexChanged will not fire since it is changed to All after the filter item is selected. The grid column is shown below. When the item is deleted I use the rebind to rebind the grid.

            <telerik:GridBoundColumn DataField="QuoteNo"
                FilterControlAltText="Filter QuoteNo column" HeaderText="Quote No"
                SortExpression="QuoteNo" UniqueName="QuoteNo">
                <FilterTemplate>
                    <telerik:RadComboBox ID="RadComboBoxQuoteNo" DataSourceID="QuoteFilterDS" DataTextField="QuoteNo" DropDownAutoWidth="Enabled"
                        DataValueField="QuoteNo" Height="200px" AppendDataBoundItems="true" SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("QuoteNo").CurrentFilterValue %>'
                        runat="server" OnClientSelectedIndexChanged="function(sender,args){FilterIndexChanged(sender,args,'QuoteNo')}">
                        <Items>
                            <telerik:RadComboBoxItem Text="All" />
                        </Items>
                    </telerik:RadComboBox>
                </FilterTemplate>
            </telerik:GridBoundColumn>

Hi Jeff,

In case you use a different DataSource to bind the RadComboBox in the filter template, there wont be any issue deleting the row, since it will be not deleted from RadComboBox source. Here is a sample code snippet i tried:

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" AllowFilteringByColumn="True" . . .>

<MasterTableView DataKeyNames="ID" CommandItemDisplay="Top" >

<Columns>

<telerik:GridBoundColumn UniqueName="ID" DataField="ID" HeaderText="ID">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="ExamID" HeaderText="ExamID" UniqueName="ExamID">

<FilterTemplate>

<telerik:RadComboBox ID="RadComboBoxQuoteNo" DataSourceID="SqlDataSource12" DataTextField="ExamID" DataValueField="ExamID" AppendDataBoundItems="true"

SelectedValue='<%#TryCast(Container,GridItem).OwnerTableView.GetColumn("ExamID").CurrentFilterValue %>' runat="server" OnClientSelectedIndexChanged="ExamIDIndexChanged">

<Items>

<telerik:RadComboBoxItem Text="All" />

</Items>

</telerik:RadComboBox>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function ExamIDIndexChanged(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

tableView.filter("ExamID", args.get_item().get_value(), "EqualTo");

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

</telerik:GridBoundColumn>

<telerik:GridEditCommandColumn ButtonType="ImageButton">

</telerik:GridEditCommandColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Thanks,
Princy

Hi Jeff,

I have created a sample RadGrid web site to test the described behavior. On my side both filtering and item delete work as expected. Can you please run the attached application and let me know about the result.

Eyup,

I also am having issues with the filter template, I looked at your project and updated the Order ID column to a Filter Template as

<telerik:GridBoundColumn DataField="OrderID" DataType="System.Int32"
FilterControlAltText="Filter OrderID column" HeaderText="OrderID"
ReadOnly="True" SortExpression="OrderID" UniqueName="OrderID">
<FilterTemplate>
<telerik:RadComboBox ID="RadComboBoxOrderID" DataSourceID="SqlDataSource3" DataTextField="OrderID"
DataValueField="OrderID" runat="server" OnClientSelectedIndexChanged="OrderIDIndexChanged"
SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("OrderID").CurrentFilterValue %>'>
<Items>
<telerik:RadComboBoxItem Text="All" />
</Items>
</telerik:RadComboBox>
<telerik:RadScriptBlock ID="RadScriptBlock2" runat="server">
<script type="text/javascript">
function OrderIDIndexChanged(sender, args) {
var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");
tableView.filter("OrderID", args.get_item().get_value(), "EqualTo");
}
</script>
</telerik:RadScriptBlock>
</FilterTemplate>
</telerik:GridBoundColumn>

The data source is defined as

<asp:SqlDataSource ID="SqlDataSource3" runat="server"
ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
SelectCommand="SELECT [OrderID] FROM [Orders]"></asp:SqlDataSource>

If I select an Order ID it will produce one record. If I select Delete I get an error

I have also moved the Filter Template to the ShipName field as

<telerik:GridBoundColumn DataField="ShipName"
FilterControlAltText="Filter ShipName column" HeaderText="ShipName"
SortExpression="ShipName" UniqueName="ShipName">
<FilterTemplate>
<telerik:RadComboBox ID="RadComboBoxShipName" DataSourceID="SqlDataSource3" DataTextField="ShipName"
DataValueField="ShipName" runat="server" OnClientSelectedIndexChanged="ShipNameIndexChanged"
SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("ShipName").CurrentFilterValue %>'>
<Items>
<telerik:RadComboBoxItem Text="All" />
</Items>
</telerik:RadComboBox>
<telerik:RadScriptBlock ID="RadScriptBlock2" runat="server">
<script type="text/javascript">
function ShipNameIndexChanged(sender, args) {
var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");
tableView.filter("ShipName", args.get_item().get_value(), "EqualTo");
}
</script>
</telerik:RadScriptBlock>
</FilterTemplate>
</telerik:GridBoundColumn>

With the datasource as

<asp:SqlDataSource ID="SqlDataSource3" runat="server"
ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
SelectCommand="SELECT DISTINCT ShipName FROM [Orders]"></asp:SqlDataSource>

If you select the Country filter then the ShipName filter for a result of a few rows when you delete the last row of that filtered data set this error appears.
