I have a .net 3.5 web form with an ajax combo box and a text box inside it. The bombo box is bound to a SqlDataSource.
My requirement is to show/hide the text box depending on the text of the selected item in the combo box. If a particular string, say 'xyz', appears in the text of the selected item, the I will make the text box invisible. I enabled the AutoPostback, made the text box disappear in the SelectedIndexChanged event, and everything worked fine.
However, when users enter their own texts (which are not in the list items), I am unable to show / hide the text box. I've tried the TextChanged event but nothing happens. It seems the event is not trigger after I enter a new text and locate the focus to other place.
is there a way to prevent the user ented text from being inserted into the bombo box?
I have a problem with the Ajax ComboBox from the Ajax Control ToolKit. When I want to erase the text in the ComboBox, I got this error:
"Microsoft JScript runtime error: '_optionListItems[...].text' is null or not an object". I only get this error when deleting the content of the Combox is the first action I do on the ComboBox. If I overwrite the text by entering something else before deleting this text, I got no error.
I have 2 tables, call them stock and visit. Stock contains a list of standard products (code and description columns). Visit contains a list of products used during a visit (product description column amongst others). When a user adds a product to the visit table they can either select a standard product from the list or select a product code and amend the description, e.g. they could select "paint" and change the description to "blue paint". The new description will only be relevant in the Visit table. This all works fine.
I have an editable gridview which lists the products used during a visit. There is an Ajax control toolkit combo box in the EditItemTemplate which allows the user to select a different product. If the product exists in the Stock list then everything works fine. If the user amended the description (e.g. changed "paint" to "blue paint" when they added the product to the Visit table I get the following error.
'ProductDescription' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I presume this is because the amended description won't exist in the standard list of products. How do I add the amended description to the combo box list? I've tried using the RowEditing event but can't reference the combo box in the EditItemTemplate.I think what I want is something along the lines of [Code]....
Combobox markup below
<asp:ComboBox ID="ProductDescription" runat="server" [code]...Answer in vb preferably.
When the WebPage loads i would like for the Text to be cleared in Ajax ComboBox and/or DropDownList. However Setting the text to nothing or null doesn't seem to work. So I did some searching and found this...
Is there another way to clear the text other then adding a null item to the list? I don't really want the user to have a selection of "null", this seems like a hack job.
I am using the combo box for my project and I am having some odd behaviour from combobox...
i am using this combobox inside a formview control...once i click on combobox it is showing the list items at the bottom of formview not next to combobox control...I think it is taking the top and left values from formview offset.
I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).
I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.
I've been trying to find an easy way of highlighting the current selected menu item of an asp.net menu (so the user knows which page they are on), but no matter what I have tried I can't get it to work. In my markup I have:
it binding correctly(datasource dynamically binded) and it raises event too while changing index but it is not raising event when we manually clearing the combobox text..if currently combobox having text "ASP" then i manually select that entire text and using del key i am deleting but it is not raising event for me.. when i change index it automatically raising event...i need to raise event while combobox is empty...
I am trying to write a page that dynamically changes the options of one drop down based off the selected item in another one. I have varified the AJAX calls are happening correctly and vaified the root problem is that the new selected value of the dropdown is not being read during the AJAX postback. The code I am using is:
ddlGameName is the dropdown that the user selects from which calls the postback and then updates another dropdown. I can place a label in the updatepanel and assign the test as ddlGameName.SelectedValue.toString() and it will always read the first item in the drop down no matter which is selected. So how can I get it to read the updated selectedValue?
The Calendar shows up when you click in the text box. And when it shows up it has no background. It is just letters and numbers, you click a number and that one appears in the textbox. I cannot use ToolkitScriptManager because the AjaxControlToolKit.ddl I have is old, I am afraid to download the newer version because this is for work and they told me to use that specific one. here is my code:
I have TabContainer, every tab has asp:lable(inside header). I want that when I select a tab, the color of text(not tab background) would be change to white.I've already read this article but it does not help in my case. also found that .ajax__tab_active .ajax__tab_tab should be involved, but I can't find the property that can change the color.
