Hi,

Try setting the RadGrid Property PageSize to '5' as shown below.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" PageSize="5" AllowPaging="true" . . .>

Thanks,
Shinu.

Hi,
Thanks for the reply.

Sorry for the confusion caused. I am not looking for paging.
I am looking for the below:

By default the user should be able to enter 5 rows one below the other.. when the user sees the grid, it should have 5 new rows created.

Hi,

I am not quite sure about your requirement. Please check the sample code snippet i tried to show 5 blank rows in RadGrid.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource"
    CssClass="grid">
    <MasterTableView CommandItemDisplay="None">
        <Columns>
            <telerik:GridTemplateColumn HeaderText="Asset Name" UniqueName="AssetName">
                <ItemTemplate>
                    <asp:DropDownList ID="txtAssetName" runat="server" />
                </ItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridTemplateColumn HeaderText="Asset No" UniqueName="AssetNo">
                <ItemTemplate>
                    <asp:TextBox ID="txtAssetNo" runat="server" />
                </ItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridTemplateColumn HeaderText="Description" UniqueName="AssetDescription">
                <ItemTemplate>
                    <asp:TextBox ID="txtAssetDescription" runat="server" />
                </ItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridTemplateColumn HeaderText="Class" UniqueName="AssetClass">
                <ItemTemplate>
                    <telerik:RadComboBox ID="rcbAssetClass" runat="server">
                    </telerik:RadComboBox>
                </ItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridTemplateColumn HeaderText="Useful Life" UniqueName="AssetUsefulLife">
                <ItemTemplate>
                    <asp:TextBox ID="txtAssetUsefulLife" runat="server" />
                </ItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridTemplateColumn HeaderText="Original Value" UniqueName="AssetOriginalValue">
                <ItemTemplate>
                    <asp:TextBox ID="txtAssetOriginalValue" runat="server" />
                </ItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

C#:

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    DataTable ds = new DataTable();
    RadGrid1.DataSource = addBlankLines(ds,5);
}
private DataTable addBlankLines(DataTable ds, int num)
{
    int count = 0;

    if (num != 0)
    {
        DataRow drBlank = default(DataRow);
        for (int i = 0; i <num; i++)
        {
            drBlank = ds.NewRow();
            ds.Rows.Add(drBlank);
        }
    }
    return ds;
}

Please elaborate your scenario if this doesn't help.

Thanks,
Shinu.

Hi,
Thanks for the reply.
This is almost working. I can see in the datatable 5 rows being created while debugging, however in the UI it shows the empty datatemplate. In the MasterTableView, i have set EnableNoRecordsTemplate="false". But still see the no records template and not the 5 rows.
How to fix this?

Did you write:  RadGrid1.DataBind() in the end?

Hello Venkatesh,

Could you please provide your code declaration in order to investigate the issue locally? Note that if you are using advanced data binding it is not necessary to call DataBind() method.
