CFGRID Selected Item as Variable

Question

Is it possible to set the value of a selected item in a
cfgrid to a variable?
I have tried this but it does not work:
<cfset UpdateID={recipegrid.selectedItem.RecipeID}>
(Throws an error)
also tried:
<cfset UpdateID="{recipegrid.selectedItem.RecipeID}">
(Just sets the variable to the string
{recipegrid.selectedItem.RecipeID} not the actual value from the
selected row.)
or
<cfset UpdateID='{recipegrid.selectedItem.RecipeID}'>
(Does the same as above.)
How can I do this?

Your attempts don't work because they assign the Coldfusion
variable
UpdateID an Actionscript value
{recipegrid.selectedItem.RecipeID}.
Use cfinput's bind attribute. For example, the following code
binds the Actionscript value {recipeGrid.selectedItem.recipeID} to
the Coldfusion variable form.UpdateID when the form is submitted.
<cfif isDefined("form.UpdateID")>
UpdateID: <cfoutput>#form.UpdateID#</cfoutput>
</cfif>
<cfset recipes = "pasta,salad,meat">
<cfset ids = "1,2,3">
<cfform name="recipes" format="flash"
action="#cgi.script_name#">
<cfgrid name="recipeGrid">
<cfgridcolumn name="recipeID" header="Recipe ID">
<cfgridcolumn name="recipe" header="Recipe">
<cfloop index="i" from="1" to="#ListLen(recipes)#">
<cfgridrow data ="#ListGetAt(ids, i)#,#ListGetAt(recipes,
i)#">
</cfloop>
</cfgrid>
<cfinput name="UpdateID" type="text" label="Update ID"
width="100" bind="{recipeGrid.selectedItem.recipeID}" />
<cfinput name="sbmt" type="submit" value="Send">
</cfform>
