[Solved] How to open / close radwindow on server side

Hi,

I have Radwindow Manager in page, Radwindow1 is opened if a condition is met on server side . User closes this window by clicking "Save" / "Cancel" Button . If "Save" button is clicked, information is processed on the server and Radwindow1 is closed.

Logic is:
If(condition1)
{
    Create a new Radwindow and add it to Radwindow Manager
    Open RadWindow1
}

SaveButton_Click( ....)
{
   .......................
   close RadWindow.....
}

Any idea?

Thanks
Prava

[Solved] Can't export to Excel...

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem dataItem = (GridDataItem)e.Item;

rev1Sum += CorrectlyParseString((dataItem["Rev1"].FindControl("Rev1Label") as Label).Text.ToString());

}

else if (e.Item is GridFooterItem)

{

GridFooterItem footer = (GridFooterItem)e.Item;

(footer["Rev1"].FindControl("Rev1Total") as RadNumericTextBox).Value = Double.Parse(rev1Sum.ToString());

}

when I'm exporting to Excel, it gives me Object reference not set to an instance of an object
Rev1 is GridTemplateColumn

I want a modal popup effect to display content on a same page on which it is using DetailsView

t looks like the only content that is to be displayed in RadWindow is the content of a page that is specified in NavigateURL. That is a problem for me because what I want to display is the dynamic content that I show on the same page on which the rad window is defined.

Is it possible to display the content on the same page defined in the rad window detailsvew?

[Solved] DataList within a RadGrid Question

I have a RadGrid that has a DataList inside of each row.
The DataList has checkboxes in them.

Example:
Let's say the grid has four rows, and the datalist inside each row has three rows itself.

When a user checks one of the checkboxes in the datalist, I need the same checkbox in the the other three rows with the same value to get checked. Would it be easier for me to do it client side or server side? Also, any help to achieve this would be great.
Here a sample of the code:

<telerik:GridTemplateColumn HeaderText="Optional Languages" HeaderStyle-Width="100%" ItemStyle-HorizontalAlign="Left" Groupable="false">

<ItemTemplate>

<asp:DataList ID="DataListl" OnItemDataBound="DataList1_ItemDataBound" RepeatLayout="Table" Width="100%" ItemStyle-BorderStyle="None" runat="server">

<ItemTemplate>

<asp:CheckBox ID="CheckboxOptional1" runat="server" />

<asp:Literal ID="LiteralOptional1" Visible="false" runat="server" />

</ItemTemplate>

</asp:DataList>

</ItemTemplate>

</telerik:GridTemplateColumn>

Create icon button (no text)

I'm trying to create a single icon button to launch a lookup window. I want the button to match the calendar popup button (Default skin) that can be viewed on this demo: http://demos.telerik.com/aspnet-ajax/calendar/examples/datepicker/custompopup/defaultcs.aspx.

I tried creating a RadButton with an icon element (and no text property) but it still has a space to the right of the button (and has the button background whereas the calendar background is transparent until rollover). Any suggections?

<telerik:RadButton ID="RadButton1" runat="server" >

<Icon PrimaryIconUrl="images/icons/find.png" />

</telerik:RadButton>

ItemTemplate missing for dynamically created template columns on rebind

I followed the example found in your documentation at the link below on programmatically creating template columns.

http://www.telerik.com/help/aspnet-ajax/grdprogrammaticcreation.html#Creating_template_columns_programmatically

This works great for the initial data binding of the grid. However, on a subsequent postback when I call Rebind the output for the column with custom item template is blank. When I use the debugger to step through the NeedDataSource event handler it appears the custom item template is no longer associated with the column. The ItemTemplate property on the column is now null.

I followed the recommendation to add the new column to the collection before setting properties.

templateColumn = new GridTemplateColumn();

rgPlans.Columns.Add(templateColumn);

templateColumn.HeaderText = "Custom Column";

templateColumn.ItemTemplate = new CustomFieldTemplate("MyCustomId");

Other non-template columns on my grid which I created dynamically seem to retain their settings.

Any ideas on why the column item template was lost?

Thanks

Horizontal Scroll not appearing in RadGrid

Hi,

1) I have a RadGrid with MasterTableView and DetailTables. There are many columns in DetailTables and because of this the last column will not be shown fully. I want the Horizontal scroll to appear so that we can see the last column properly. I have added the code <Scrolling AllowScroll="True" ScrollHeight="50px" UseStaticHeaders="true" /> but still the Horizontal scroll is not appearing. How to achieve this?

2) If I enter data in textbox (in RadGrid) and go to Page 2 and come back again to Page 1, the data entered in Page 1 will be lost. I want to retain the values in the grid after Paging. How to retain the data after pagination?

The browser I am using is IE8.

I have also attached the code and screenshot. Please provide the solution for the queries.

[Solved] Try to get AsyncUpload worked with RadProgress

Hi, I've been trying to get AsyncUpload worked with RadProgress. All I got is "undefined" JavaScript error (see attached).

I've placed RadScriptManager in Master page, TemplateMain.master, and AsyncUpload, RadProgressManager, RadProgressArea in my "Default.aspx" which implements TemplateMain.master.

Any idea with this error?

Thanks
