radtab formatting css

Hi, I'm using the tabstrip with rendermode="lightweight" and skin="metrotouch" I'm trying to override some css to change some colors;

eg .selectedtab{background:#16a085 !important;}.RadTabStripTop {background:red !important;}

All working fine, except struggling to find what controls the strip below the tabs. See attached dump - blue strip across entire control. Need to change this color.....

Any suggestions please?

Using rad button and rad dropdown list to link to a sorted radgrid.

Hey, so I'm trying to use a rad dropdown and a rad button that will, when a value is selected, link to a rad grid that is then automatically sorted by the value chosen.

<telerik:RadDropDownList ID="RadDropDownList1" runat="server" DataTextField="Org" DataValueField="Org" DefaultMessage="Org List" DataSourceID="orgDropDown" Skin="Office2010Black"></telerik:RadDropDownList>

<br />

<telerik:RadButton ID="RadButton2" runat="server" Text="RadButton" ButtonType="LinkButton" Skin="Office2010Black"></telerik:RadButton>

protected void RadButton2_Click(object sender, EventArgs e)

{

DropDownListItem selectedItem = RadDropDownList1.SelectedItem;

if (selectedItem != null)

{

}

I have this so far but I'm absolutely lost as to what to do next.

Slider not showing units

Hi,

I have a slider declared as follow:

<telerik:RadSlider

ID="RdSldr_Threshold"

runat="server"

ItemType="Tick"

MinimumValue="10"

MaximumValue="100"

LargeChange="10"

Orientation="Vertical"

TrackPosition="Center"

Height="200px"

Width="70px"

AnimationDuration="100"

ThumbsInteractionMode="Free"

EnableEmbeddedBaseStylesheet="false" EnableEmbeddedSkins="false"

EnableServerSideRendering="true">

</telerik:RadSlider>

With this declared before:

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

<telerik:RadStyleSheetManager ID="RadStyleSheetManager1" runat="server">

<StyleSheets>

<telerik:StyleSheetReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Skins.Slider.css" />

<telerik:StyleSheetReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Skins.Default.Slider.Default.css" />

</StyleSheets>

</telerik:RadStyleSheetManager>

The problem is that while the slider renders properly, I see not ticks on the side of it.

Any idea what causes this?

This is a pretty urgent issue for us.

Thanks

Trying to capture when an item is transfered from list A to list B

Hello,

I am trying to capture when an item is transferred from the list RadListBoxSource to the listbox lbSupervisors. I have put breakpoints on lbSupervisors_Inserted, lbSupervisors_Inserting, lbSupervisors_Transfered, lbSupervisors_Transfering and none of them are being hit when I transfer an item from RadListBoxSource to lbSupervisors. Please tell me why these breakpoints are not being hit.

Thanks,

Stephen

Readonly Column at run time

Hi There
I have a bit odd requirement inside a grid. What I am looking for is.
I have grid which consist of Year column and all the 12 month(July, August,….June) and total Budget amount.
This grid could have many rows for different phases of the project (Concept, Design, Construction etc)
Now my task is do the phasing for that budget at runtime.
At run time I know which months (based on Dates Stored somewhere) I need to put the budget and based on that I have to divide this amount into these months and make all other month as read only.
I have to make sure that sum of all the month should be equal to total budget amount at client side
For example first row might be Design which might start from August and finish at October so remaining column for other months should be read only
Second row might be construction which might start from October and finish at December so remaining column for other months should be read only.
I hope this would be clear enough
Please let me know how to achieve this.
I will really appreciate that and look forward to hear from you all
Many thanks
Syed
