Changing Tile Title Styling from Code Behind

[Silviu]

I have a RadContentTemplateTile with a default Title colour of Black set via

.rtileTitle
    {
         color: Black !important;
    }

Sometimes I have the need to change the Black to Red and I'd like to do it via CSS as below.

.rtileTitleRed
    {
        color: Red !important;
    }

 

The trouble is, I don't know how/where to apply this CSS in code behind. Please assist.

Hello Silviu,

You can set only CSS class names in code behind by the CssClass property and after that apply the mentioned styles regularly in your CSS file.

Hi Magdalena,

I have tried that already by setting the tile's CssClass but the changes were not applied. Could not see them applied when debugging IE with F12 either.

RadContentTemplateTile tile = myControl.FindControl("radTile") as RadContentTemplateTile;
tile.CssClass = "rtileTitleRed";

Hello Silviu,

Here is an example that works, with explanations:

/*you need a selector heavier than the built-in in order to override the rule*/
html div.RadTile.customTitleColor h6.rtileTitle
{
    color: green;
}

/*you need to incorporate the new class in the current selector, you cannot just append the color to the selector*/
html div.RadTile.customTitleColor.redTitle h6.rtileTitle
{
    color: red;
}

<telerik:RadContentTemplateTile runat="server" ID="RadContentTemplateTile1" Title-Text="click for red" CssClass="customTitleColor" OnClick="RadContentTemplateTile1_Click" AutoPostBack="true">
</telerik:RadContentTemplateTile>

protected void RadContentTemplateTile1_Click(object sender, EventArgs e)
{
    RadContentTemplateTile1.CssClass="customTitleColor redTitle";
}

You may also find useful some tutorials in the Internet on CSS selectors and their specificity, like these ones:
