And CS is

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                RadGrid1.Visible = true;
            }
        }

        protected void btnHome_Click(object sender, EventArgs e)
        {
            Response.Redirect("Home.aspx");
        }
        protected void ddlItems_SelectedIndexChanged(object sender, EventArgs e)
        {
            DropDownList ddlItems = (DropDownList)sender;
            GridEditFormItem editItem = (GridEditFormItem)ddlItems.NamingContainer;
            GridDataItem item = (GridDataItem)editItem.ParentItem; // access GridDataItem
            Label lblRate = (Label)item.FindControl("lblRate"); // access Label using DataItem
            if (ddlItems.SelectedIndex > 0)
            {
                DataSet ds = objSQLHelper.GetProductDetails("select * from tblProducts where Pid=" + ddlItems.SelectedValue);
                if (ds != null)
                {
                    lblRate.Text = ds.Tables[0].Rows[0]["Rate"].ToString();
                }
            }
        }

        protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if ((e.Item is GridEditFormItem) && (e.Item.IsInEditMode))
            {
                GridEditFormItem editform = (GridEditFormItem)e.Item;
                e.Item.Edit = true;
                DropDownList ddlItems = (DropDownList)editform.FindControl("ddlItems");
                ddlItems.DataSource = SqlDataSource1;
                ddlItems.DataTextField = "ProductName";
                ddlItems.DataValueField = "Pid";
                ddlItems.DataBind();
            }
        }
        private void RadGrid1_PreRender(object sender, System.EventArgs e)
        {
            if (!IsPostBack)
            {
                foreach (GridItem item in RadGrid1.MasterTableView.Items)
                {
                    if (item is GridEditableItem)
                    {
                        GridEditableItem editableItem = item as GridDataItem;
                        editableItem.Edit = true;
                    }
                }
                RadGrid1.Rebind();
            }
        }
        protected void RadGrid1_ItemCreated(object sender, EventArgs e)
        {

        }
        protected void RadGrid1_ColumnCreated(object sender, EventArgs e)
        {

        }
        protected void RadGrid1_NeedDataSource(object sender, EventArgs e)
        {

        }
        protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
        {
            if (e.CommandName == "RowClick")
            {
                RadAjaxManager manager = RadAjaxManager.GetCurrent(this.Page);
                manager.Alert("Row was clicked!");
                this.RadGrid1.DataSource = new object[] { };
                this.RadGrid1.DataBind();

            }
        }

I need to show an empty grid which will be used for inserting records.than the records within table would be saved to the database.I am takin dataset ds as datasouce but that also does'nt work..

m@dhu 8-Oct-10 2:00am

If the dataset is empty obviously the grid will be empty and
without binding the grid how can the grid be visible?

AmitChoudhary10 8-Oct-10 2:47am

Than what to do?...I have to show the grid empty in edited mode.

m@dhu 8-Oct-10 4:57am

May not be the best, Clear the dataset in the edit mode which makes grid empty.

Solution 2

Do you really need below block?

C#

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                RadGrid1.Visible = true;
            }
        }

Remove the line

RadGrid1.Visible = true;

from Page_Load()

Also check while debugging can you able to data in the dataset?

I need to show an empty grid which will be used for inserting records.than the records within table would be saved to the database.So there will be no data Item initially in the grid.removed RadGrid1.Visible = true;.still not visible.
