object reference error on Insert command

[Venkatesh]

HI,

I have added the radgrid and have the insert command. I do not have the ajax added to the page. when a new item is added, item.extractvalues count is empty. How to retrieve the inserted values.
Below is the current code:

<telerik:RadGrid ID="radgrid1" runat="server" EnableViewState="true"
        ShowFooter="True"
        OnInsertCommand="radgrid1_InsertCommand"
        OnNeedDataSource="radgrid1_NeedDataSource">

        <MasterTableView DataKeyNames="ProductNumber" AutoGenerateColumns="false" EditMode="InPlace"
            CommandItemDisplay="TopAndBottom" CommandItemSettings-AddNewRecordText="Add New Item">
            <Columns>
                <telerik:GridEditCommandColumn ButtonType="ImageButton">
                </telerik:GridEditCommandColumn>
                <telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow"
                    ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" ConfirmDialogHeight="100px"
                    ConfirmDialogWidth="220px">
                </telerik:GridButtonColumn>

                <telerik:GridTemplateColumn DataField="ProductNumber" HeaderText="Product Number" UniqueName="ProductNumber"
                    Visible="true">
                    <InsertItemTemplate>
                        <telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text="">
                        </telerik:RadTextBox>
                    </InsertItemTemplate>
                    <EditItemTemplate>
                        <telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text="">
                        </telerik:RadTextBox>
                    </EditItemTemplate>
                    <ItemTemplate>
                        <telerik:RadTextBox ID="RadtxtPrdNumber" ReadOnly="true" runat="server" Text="" />
                    </ItemTemplate>
                </telerik:GridTemplateColumn>

</Columns>
        </MasterTableView>
        <ClientSettings EnableRowHoverStyle="true">
        </ClientSettings>
    </telerik:RadGrid>

protected void radgrid1_InsertCommand(object sender, GridCommandEventArgs e)
        {

                GridEditableItem item = e.Item as GridEditableItem;
                Hashtable values = new Hashtable();

                item.ExtractValues(values);

}

How to fix this?
Thanks

Hi,

Here is the sample code that I tried to get new values in InsertCommand.
C#:

protected void RadGrid1_InsertCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
{
    GridEditableItem editedItem = e.Item as GridEditableItem;
    Hashtable newValues = new Hashtable();
    e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);
}

Thanks,
Shinu.

HI,
This code is not working for me.
I tried this:

DataTable purchaseOrder = this.PurchaseOrderData;

GridDataInsertItem item = (GridDataInsertItem)e.Item;

RadTextBox txtProductNumber = (RadTextBox)item.FindControl("RadtxtPrdNumber");
string strProductNumbervalue = txtProductNumber.Text;

I am getting the value for the first row insertion. when i insert the second row, the value is coming as empty.
How to fix this?
Thanks

Hi,

Unfortunately I cannot replicate the issue at my end. Here is the code that I tried to get new values on insert and update.
aspx:

<telerik:GridTemplateColumn HeaderText="template">
   <EditItemTemplate>
      <telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text=""></telerik:RadTextBox>
   </EditItemTemplate>
</telerik:GridTemplateColumn>

C#:

void RadGrid2_InsertCommand(object sender, GridCommandEventArgs e)
{
        GridDataInsertItem item = (GridDataInsertItem)e.Item;
        RadTextBox txt = (RadTextBox)item.FindControl("RadtxtPrdNumber");
        string value = txt.Text;
}
void RadGrid2_UpdateCommand(object sender, GridCommandEventArgs e)
{
    GridEditableItem editedItem = (GridEditableItem)e.Item;
    RadTextBox txt = (RadTextBox)item.FindControl("RadtxtPrdNumber");
    string value = txt.Text;
}

Thanks,
Shinu.
