Where is ScriptManager.IsStartupScriptRegistered method?
- by Ismail S
Below is my code
if (!Page.ClientScript.IsStartupScriptRegistered(Page.GetType(), scriptKey))
{
ScriptManager scriptManager = ScriptManager.GetCurrent(page);
if (scriptManager != null && scriptManager.IsInAsyncPostBack)
{
//if a MS AJAX request, use the Scriptmanager class
ScriptManager.RegisterStartupScript(Page, Page.GetType(), scriptKey, script, true);
}
else
{
//if a standard postback, use the standard ClientScript method
Page.ClientScript.RegisterStartupScript(Page.GetType(), scriptKey, script, true);
}
}
I'm doing as suggested in this answer so that I can register startup script on both times i.e. when there is partial postback and a full postback.
The problem is Page.ClientScript.IsStartupScriptRegistered(Page.GetType(), scriptKey) always returns false when it is partial postback. And I couldn't find ScriptManager.IsStartupScriptRegistered method. As a result of this additional script is emitted on all partial/async postbacks.
Please note that I'm using script manager of AjaxControlToolkit version 4.1 i.e. ToolkitScriptManager in my masterpage. But I don't thing it has something to do with this.
