以下のコード スニペットを試してみてください。
ASPX
<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" OnNeedDataSource="RadGrid1_NeedDataSource"
OnUpdateCommand="RadGrid1_UpdateCommand" AllowFilteringByColumn="true" AllowPaging="true"
AllowMultiRowEdit="true">
<MasterTableView DataKeyNames="ID" EditMode="InPlace">
<Columns>
<telerik:GridBoundColumn DataField="ID" UniqueName="ID" HeaderText="ID">
</telerik:GridBoundColumn>
<telerik:GridEditCommandColumn>
</telerik:GridEditCommandColumn>
</Columns>
</MasterTableView>
</telerik:RadGrid>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="update All edit row" />
ASPX.CS
protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
dynamic data = new[] {
new { ID = 1, Name = "Name1"},
new { ID = 2, Name = "Name2"},
new { ID = 3, Name = "Name3"},
new { ID = 4, Name = "Name4"},
new { ID = 5, Name = "Name5"}
};
RadGrid1.DataSource = data;
}
protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)
{
GridEditableItem item = e.Item as GridEditableItem;
UpdateLogic(item);
}
protected void Button1_Click(object sender, EventArgs e)
{
foreach (GridEditableItem item in RadGrid1.EditItems)
{
UpdateLogic(item);
item.Edit = false;
}
RadGrid1.Rebind();
}
protected void UpdateLogic(GridEditableItem item)
{
// perform your update logic here
}
