View 3 RepliesI want to improve the performance of my web application. Whenever the page loads, it is taking 70-80% of CPU usage.
I'm using ajax timer controls to update the user controls on my page. Also I placed user controls in the update panels of my page.
How to avoid high CPU usage ?
I have seen this discussed in number of topics, but so far nothing to address my specific issue. I want to display the page the client, and then trigger an updatepanel refresh that will populate with data that takes 3-4 seconds to load (the rest of the page loads very fast). At the same time I want to display "...Loading..." text using UpdateProgress control.
Everything is working below in the sample code. However, UpdateProgress will not display unless the button is actually clicked by the user. In real production scenario I would hide the button. To invoke the immediate UpdatePanel refresh I trigger the click via Javascript. I have also tried "__DoPostBack" without success.

I am making a menu to display departments and sub departments. Each department has a corresponding pop-up menu to display the sub departments. The menu is built dynamically with values from the database. I'm using nested repeaters and the AJAX HoverMenuExtender. The problem is that when the page loads or is refreshed all of the sub departments are visible for a second or so underneath their respective subdepartments. In other words, for just a second the page is rendered as if the HoverMenuExtender was not there.

View 9 RepliesI want masked ComboBox, so I use a MaskedEditExtenderwith a ComboBox. The two controls came from the ajax control toolkit. But I got an error: "Unable to cast object of type 'AjaxControlToolkit.ComboBox' to type 'System.Web.UI.WebControls.TextBox'". Is there a way a can use a MaskedEditExtender with a combo box?
View 4 RepliesCan I provide a Combobox that will EITHER let a user type in a value OR let them select from the dropdown? I am trying to create a scenario where a user can attach a value to an object they are editing. When attaching that value, I want them to be able to type in a completely new value or, select from a list of already-existing values.
When I create the combo box, I add a list item that has text like "Type a value or pick from the list"...this has an index of 0. Then I append the databound values to the list.
A combo box seems like the perfect solution since it combines a text box with a drop down list but, I can not figure out how to retrieve the text that has been typed into the combobox once the form is submitted. cmbMyComboBox.text seems to be the obvious way to do it but, that returns an empty string. If I try to get the SelectedItem.Text then, I get "Type a value or pick from the list" instead of whatever text I typed into the combobox, once it was displayed.
Am I trying to do something that the ComboBox is not meant to do? How can I accomplish this?
I have decided to abandon trying to use the combo box. I am trying to use a dropdown menu in one column, and text boxes in all the others. But, I am having a strange problem with that as well. I will post those problems in the appropriate forum. I marked this post as "No Status" because I didn't see any way to delete it.
When i select or autosuggest in a combo box , i should be able to get the selected value in a text box in the client side using ajax without a postback.

View 2 RepliesI have a very typical set up, an ajax update panel is updated when a drop list of offices changes. Each form could have it's own values, for instance each store will have it's own list of employees. Here is where the fun begins. The form can be changed by the drop down (new office) or validated and submitted.
On drop down change, I create a new instance of the same rad combo, bind it to the current data, confirm that the correct data is bound. Then on the return trip I see selected the default user from the previous user. This is a composite control, and firebug shows me that the value for the "text box" that simulates the combo still has the old value. I'm suspecting onViewStateLoaded, but turning viewstate off for the Telerik didn't . II don;t need it anyway, cuz I have to put the selected value in another hidden to make a cross page post on submit.
I have an Ajax Toolkit combo box in DropDownStyle Mode. The DropDownStyle should prevent the user from entering values that are not in the list of items of the combo box. The problem is, if the user paste some text (right-click --> past OR ctr + V) in the combo box, it will work, event if the pasted text is not the list of items. Is there a way I can prevent this?

View 3 RepliesI have an Ajax Toolkit Combo Box in DropDown Style (to allow user to enter custom value). The event SelectedIndexChanged and TextChanged works fine if the user select an item of the list of the combo box.
The problem is if the user enter a value that is not in the list of the item of the combo box, the event SelectedIndexChanged nor TextChanged are fired. Is there a way to "force" those events to be fired?
I'm using the Ajax control toolkit Combo box for filtering purpose. If the number of items in the combo box is more and when i try to select an item in the drop down list, the scroll bar in the list automatically flickers in Internet explorer.I read the known issues section in the Asp.Net Ajax control toolkit website, and they say that When ListItemHoverCssClass is specified and the ComboBox list is scrollable, highlighting a list item will cause the scrollbar to flicker when using the Internet Explorer web browser. To avoid this issue, do not specify the ListItemHoverCssClass property.Am not using any ListItemHoverCssClass Property but still it flickers. Please help me on any work around to solve this. I know Auto Complete extender is a best solution instead of combo box, but the clients need combox that should list everything along with editing in the text box.
