Problem with template filter for datetime column

Hi,

I'm testing RadGrid filters and I have problems with template filters.

I want to have a template filter for a column binded to a datetime datafield, for filtering between two dates. The template has these controls:
   - a Date picker for start date.
   - a Date picker for end date.
   - a button to apply/clear the filter.

These are pieces of the code I'm using:

- ASPX:

...

<telerik:GridBoundColumn DataField="DateTimeFieldDB"

DataType="System.DateTime"

FilterControlAltText="Filter DateTimeFieldDB column"

HeaderText="Date/Time" SortExpression="DateTimeFieldDB"

UniqueName="DateTimeCol" HeaderButtonType="LinkButton">

<HeaderStyle Width="150px" />

<FilterTemplate>

<telerik:RadDatePicker ID="FromDT" runat="server" Width="70px"/>

<telerik:RadDatePicker ID="ToDT" runat="server" Width="70px"/>

<telerik:RadButton ID="btnFilterDT" runat="server" Text="Filter" CommandName="cmdFilterDT">

</telerik:RadButton>

</FilterTemplate>

</telerik:GridBoundColumn>

...

- CS:

protected void myGrid_ItemCommand(object sender, GridCommandEventArgs e)

{

switch (e.CommandName)

{

case "cmdFilterDT":

GridColumn column = myGrid.MasterTableView.GetColumnSafe("DateTimeCol");

GridItem[] fItems = myGrid.MasterTableView.GetItems(GridItemType.FilteringItem);

RadDatePicker dpFrom = (RadDatePicker)fItems[0].FindControl("FromDT");

RadDatePicker dpTo = (RadDatePicker)fItems[0].FindControl("ToDT");

string sDateFrom = string.Format("{0: dd/MM/yyyy}", dpFrom.SelectedDate);

string sDateTo = string.Format("{0: dd/MM/yyyy}", dpTo.SelectedDate);

if (dpFrom.SelectedDate.ToString() != string.Empty && dpTo.SelectedDate.ToString() != string.Empty)

{

column.CurrentFilterFunction = GridKnownFunction.Between;

column.CurrentFilterValue = string.Format("{0} {1}", sDateFrom, sDateTo);

}

else

{

column.CurrentFilterFunction = GridKnownFunction.NoFilter;

column.CurrentFilterValue = "";

}

myGrid.MasterTableView.Rebind();

break;

}

When I click the filter button the command is fired and the code for 'cmdFilterDT' is executed, but no changes are displayed in the grid (I have a rule from myGrid to myGrid in an RadAjaxManager for refreshing the changes).

Anyone can help me? I've been reading the help and the grid forum but I don't find any solution to this method for using template filters.

Thanks in advance,
John.

Dynamic Column Selection

It would be nice to have context menu on the columns of the grid that define which columns display (like windows explorer does).

Does the RadGrid support this or does anybody know a way this can be easily done?

var MobileCombo = $find("<%= RadcbCustomersMobile.ClientID %>");

var ComboItem = MobileCombo.findItemByValue(sender.get_selectedItem().get_value());

MobileCombo.trackChanges();

if (ComboItem != null)

ComboItem.select();

MobileCombo.commitChanges();

}

function OnClientSelectedIndexChanged_RadcbCustomersMobile(sender, eventArgs) {

var EmailCombo = $find("<%= RadcbCustomersEmail.ClientID %>");

var ComboItem = EmailCombo.findItemByValue(sender.get_selectedItem().get_value());

EmailCombo.trackChanges();

if (ComboItem != null)

ComboItem.select();

EmailCombo.commitChanges();

}

my syntax is ok , but i have a logical error about these codes / it seems there is a loop here / how can i prevent this loop?

thanks in advance
best regards

Upload image via URL

I was wondering if RadUpload control has a built-in "upload via url" feature. I know i can use HttpWebRequest/Response classes but would be nice if you just paste the image url to the radupload and let it take care about the rest.

Virtual Paging in Rad Grid

Hello,

I have used Rad Grid on my web page, I had applied Virtual Paging on my radgrid, my page size is 30 for radgrid, After page loaded grid have 210 records ,so there would be 7 total pages, i have put down the grid into the rad pane so initially there are 15 visible records available.Now, the problem with virtual pagins is when scroll the page user will get rest of the records but when user reach up to 25 records, automatically paging get applied and come to the second page means records will display from 31-60...so in that case user can't able to view the records 26-30 those are the part of First Page. How can i manage the index of the records or any other solution to resolve this issue. same thing happen while i am editing any records which are near to paging (i.e. record 28 or 29).
