How to change a controls SkinID at runtime (asp.net 2.0)


S

stephen.mcallister

I am toying around with Personalization in asp.net 2.0 and would like
my users to be able to choose a SkinID at runtime.
I have a theme with a default gridview skin and a custom skin.
There are 2 buttons on a Control that I was hoping I could use to
switch the SkinID, but it appears it's not that easy to do during
runtime.

Here is the code I tried to use

protected void imgBtnDefaultColour_Click(object sender,
ImageClickEventArgs e)
{

gvReqListing.SkinID = "";

}
protected void imgBtnSecondColour_Click(object sender,
ImageClickEventArgs e)
{
gvReqListing.SkinID = "gvWebPart";

}

and the error message that I received

The 'SkinId' property cannot be changed dynamically if Page has a
stylesheet theme. For dynamic controls, set the property before calling
ApplyStyleSheetSkin().

Any help or suggestions would be greatly appreciated.

Change theme at runtime (asp.net 2.0)

you use session to save your setting, after that redirect site,like this:
protected void rad1_SelectedIndexChanged(object sender, EventArgs e)//rad1 is radioButtonList
{
Session["themesPage"] = rad1.SelectedValue;
Server.Transfer(Request.Path);
}

at method Page_PreInit, you use:
protected void Page_PreInit(object sender, EventArgs e)
{
string thm;
thm = (string)Session["themesPage"];
if (thm != null && thm != string.Empty)
{
Page.Theme = thm;//name theme
rad1.SelectedValue = thm;
}
else
{
Session["themesPage"] = rad1.SelectedValue;
Page.Theme = "theme1";//name theme
}


Good luck :driver:
