RadGrid Insert Form

[Sunil]

Hello,

I am using a RadGrid and I want to insert a new item into the grid using the built-in RadGrid functionality.  The new item has been defined as follows:

<EditFormSettings EditFormType="Template">

<FormTemplate>

<div>

<h3>

New Team Culture Assessment

</h3>

<table>

<tr>

<td>

<asp:Label ID="EntitiesLabel" runat="server" Text="Entities"></asp:Label>

</td>

<td>

<asp:DropDownList ID="EntityList" runat="server" AutoPostBack="True"

OnSelectedIndexChanged = "Entity_selected">

</asp:DropDownList>

 

</td>

</tr>

<tr>

<td>

<asp:Label ID="TeamsLabel" runat="server" Text="Teams"></asp:Label>

</td>

<td>

<asp:DropDownList ID="TeamList" runat="server">

</asp:DropDownList>

</td>

</tr>

</table>

</div>

</FormTemplate>

</EditFormSettings

My questions:

1.  I want to populate the EntityList and TeamList drop-downs in the page-load using "object data source", but when I access them directly, I am getting an error saying that the name EntityList is not found in current context...here is what I am doing in !postback in page_load:

var bd = new BfEntityDAO();

List<BfEntity> ents = bd.GetEntities();

EntityList.DataSource = ents;

EntityList.DataTextField = "BfEntityName";

EntityList.DataBind();

How can I populate these drop-downs so that the user can see the values when he inserts a new item?

2.  When the user opens the insert form and selects an entity from the entitylist drop-down, I want to populate the teamlist drop-down based on the value selected in the entitylist drop-down.  How can I accomplish this?

This is the code snippet I am using currently in the codebehind, but the method is not being called:

 Method called when item in entity drop own list selected

===========================================

try
{

var cd = new TeamDAO();

List<Team> teams = cd.GetTeamsForEntity(entityDropDown.SelectedValue);

teamDropDown.DataSource = teams;
teamDropDown.DataTextField = "TeamName";
teamDropDown.DataValueField = "Id";
teamDropDown.DataBind();

}
catch (Exception ex)
{
Common.Utils.HandleException(ex);
}

3.  Finally, when the user clicks OK on the form, I want a insert the data into the database from the code-behind file. How can I get a callback to method in the code-behind and how can I access the data entered by the user?

Thank you

Hi Jayesh,

Thank you for the information.  I don't need edit/update, only insert.  

I have a quick follow-on question.

1. I am assuming that when the user clicks the insert button, the Grid_InsertCommand method is called.  Here, I am populating the two drop-downs using the object datasource in the code behind.

2.  When the user selects the entities drop-down, I am assuming that the Entity_Selected method is called in the code-behind.  I am populating the team dropdown based on the selected entity value

3.  Which method in code-behind is called when the user clocks the OK button on the form to insert the form data?

Hi,

You can populate the dropdownlist in insert mode as shown below.
C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

        if (e.Item is GridEditFormInsertItem && e.Item.OwnerTableView.IsItemInserted)

        {

            GridEditFormInsertItem item = (GridEditFormInsertItem)e.Item;
           DropDownList EntityList = item.FindControl("EntityList") as DropDownList;

        }
}

When user clicks Ok button,UpdateCommand event is fired. Also check the demo for more.
