Multiple selection in the Master grid not being retained on PostBack

I have to two Rad Grids functioning as master details linked by this select parameter, I need to make multiple selection on both grids , the problem I have is the multiple selection in the master grid is not being retained in the detail grid on post back. How can I make multiple selection in the master grid and filter by that multiple selection in the details grid?
the experience I am getting right now is the selection selection is used for the controlparameter value but I need to use all the selected values?
<SelectParameters>
<asp:ControlParameter ControlID="RadGrid1" Name="Region" PropertyName="SelectedValue" Type="String" DefaultValue="All" />
</SelectParameters>
Thanks

how to record the button clicked state and use it in usercontrol

Hello!

I used the code( tabs and grid) in sales dashboard. Now I want to record the three buttons (search, reset, clear) clicked state so that I can use it in the user control . When three buttons clicked then I will always get data from database and for other postbacks I only use session variable.

How could I do it? I used session to record the clicked state and pass it to usercontrol property. but I don't think it will work as when other postback the session still hold the clicked( true) value.

Thanks for any help in advance!

custom stylesheet for radFormDecorator not being applied

I have followed the instructions on http://www.telerik.com/help/aspnet-ajax/radformdecorator-creating-custom-skins.html to create a custom stylesheet but it does not seem to be applying. I have created a directory called CustomSkins and copied the FormDecorator.Forest.css file and the FormDecorator directory to it, just as a test I added a link to the css and set EnableEmbeddedSkins=False. Shouldn't that pick up and apply the Forest colors and look the same as if embedded skins was turned on and selected Forest. But in my page I'm getting no stylesheet settings. What we want to be able to do is us all the telerik styles but add items to the telerik stylesheet to handle things we have already incorporated in our apps.

<

head runat="server">

<div>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

<telerik:RadFormDecorator ID="RadFormDecorator1" Runat="server" DecoratedControls="All" EnableEmbeddedSkins="false" />

OnImageChanged

I seem to be unable to get the OnImageChanged server-side event to fire ... tried with an empty project with default.aspx content:

<div>

<telerik:RadImageEditor ID="RadImageEditor1" runat="server" OnImageChanged="RadImageEditor1_ImageChanged"

ImageUrl="~/images/160004.jpg">

</telerik:RadImageEditor>

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><telerik:RadButton

ID="RadButton1" runat="server" Text="PostBack" AutoPostBack="true">

</telerik:RadButton>

</div>

And in the code-behind:

protected void RadImageEditor1_ImageChanged(object sender, Telerik.Web.UI.ImageEditorEventArgs args)

{

Label1.Text = System.DateTime.Now.ToString();

}

It seems the Label's text never gets updated ...

What am I doing wrong here ?

Combine ImageEditor control with...

I have a RadGrid which currently allows for uploading an image from the local machine, and after which it displays in the grid. The image itself is stored in the database. Would it be possible to inject the ImageEditor control into this sequence so people could essentially upload their picture - make an edit if necessary - and then have the grid store the edited image to the database as it currently does?

RadImage Editor Dialogs z-index

Hello,

I have been trying to modify the z-index of the dialog box for cropping without success. Can you point me the right css class or way to do this? right now the editor is in a control with a z-index of 100001 and therefore when the crop button is pressed the dialog shows behind the editor.

Thanks

I'm using a radgrid which looks up against a datatable.

I need to be able to configure/set what the default values are, which are assigned to the new row When the "Add a New Record" button is pressed.

Is this possible? Currently it returns nulls.

When the search button is pressed a radgrid is binded depending on the value of the textboxes, the radgrid has enable paging=true, after hitting the search button the textboxes are cleared the when I try to change page,the grid is not binded because there's no value in the textboxes, My question is if is it posible that after clear the textboxes and change the page of the radgrid keep the last value of the textboxes?

Get all values from columns of each row

Hi all.

i have been trying to get Cell values from Radgrid. The columns can be items templates (textbox, combo, etc ) and can be simply data binding columns. I tried:

foreach (Telerik.Web.UI.GridDataItem dataItem in grdShippedOrders.MasterTableView.Items)
{
int OrderID = Convert.ToInt32(dataItem.GetDataKeyValue("OrderID"));
}

----------------------------------------

GridFooterItem footer = (GridFooterItem)grdShippedOrders.MasterTableView.GetItems(GridItemType.Footer)[0];
int order = Convert.ToInt32(footer["OrderId"].ToString());

-----------------------------------------

CompanyName = (grdShippedOrders.MasterTableView.FindItemByKeyValue("orderId") as GridDataItem)["orderId"].Text;

I know how to get the value froma control (textbox, checked) but i can't get the value of a column with data binding source. I need to get each value from each column and row. I tried with for(...){ .......... } too.

Please help me.
