How to make the text for radiobuttonlist disappear
<asp:radiobuttonlist id="radio1" runat="server">
The pages text are modified and styled with an HTML editor (teleric). The resulting html is stored in a database. The html and style tags are stored with the text ofcourse.
Now, sometimes the HTML tags are DELETED from the text! I realize this has happened first when i see the page text totaly plain on the site. Then i go to the databse and check, and the HTML tags and styling is not there anymore!
The only thing i can think of that could be reason is a method i wrote to search in the text. It strips the texts from html tags so that only the main text will be used when searching for the string that the user has asked for. But the modified texts without HTML tags are not saved to the database. I use LINQ and i never call a SubmitChanges();

In a project of mine I dynamically create controls and add them to the nodes of a radtreeview (a control by telerik) in theLoadViewState event. By the end of this event everything seems fine, but as soon as the
Page_Load event fires the controls have disappeared. No code of mine is executed during this phase.
I'd love to know why this is the case,
I have a couple of dropdowns in my form and each item having tooltip. Upon postback these tooltip texts are not getting displayed
I did displaying tooltip using .Attributes.Add("title","mytooltiptext");
I have following controls on my page
<asp:Button ID= "Submit" runat="server" CausesValidation="true".....>
<asp:textBox ID="txtPrice" runat="server" ...../>
<asp:Button ID="btnReset" runt="server" OnClientClick="ResetPriceBox(); return false"/>

I am an asp.net newbie and encountered problem with postback. I have created a web form and put some web controls and set their AutoPostBack property to True.
Some of the controls are listbox, checkbox. However, the SelectedIndexChanged and OnCheckChanged do not fire automatically when an item is selected from the listbox for example or when the checkbox is checked. I noticed that the commands I put in the SelectedIndexChanged and OnCheckChanged is only fired when a button is clicked.
e.g. The code below that sets the text of a label is being fired only when a button is clicked even if the autopostback property of the listbox is set to TRUE.
protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
{
ListItem myItem = ListBox1.SelectedItem;
Label1.Text = myItem.Text;
}
Again, I would like the Label's text to change when an item is selected from the listbox and not only when a button is clicked.
What else could I be missing to make autopostback work?

I created a web part called 'staff phone search'. There are two controls 'Button' and 'Textbox' in it. The web part is inherited from Webcontrols webpart class not from sharepoint web part.My problem is that if I fill the search keyword text box and click the button, the text box and the button disappear. However the webpart displays result properly. Subsequently I am not able to search again because the web part never shows the controls again. How can I keep the controls after the webpart is submitted?
My code can be found below.
public class WebPart1 : System.Web.UI.WebControls.WebParts.WebPart
{
TextBox _myTextBox;

I have a GridView in MultiView and everything works fine. When page load everything looks good,but then when i try to edit something in my gridview it does postback and the whole gridview disappear from the multiview.
View 1 RepliesI have a gridview in which i have declared one static templatefield (with some button ctrls inside) in design itself.
I add the remaining columns to it as a dynamic templatefield by inheriting the ITemplate interface.
My problem is that now when i cause some postback for the firsttime after the Gridview is bounded, it works fine. But when i cause some postback for the second time, all the controls in the static templatefield disappears.
below is my code

I have a checkbox column in a Gridview that is added in the aspx and the other columns are added in the code behind. The checkbox is a choice to print the record or not. When the print button is pushed the page posts back and the checkboxes are gone.
I have read that you have to re-add the checkboxes on postback, but where do you do that and how do you retain the viewstate values - checked/not checked? I have tried everywhere - PreInit, PreLoad, PreRender... I can't get the viewstate values to appear anywhere. The checkboxes can be added just about anywhere but the vaules are set to "unchecked" by default... no values ever come back no matter where I re-add them.
I already implemented the dynamic templatefield which will re-created in every postback. Everytime I make a postback in the page I see no problem but when I click my imagebutton inside the gridview then the dynamic templatefield disappear.
To double check if it is really gone at all I just select the second page of the gridview using my customize paging using dropdownlist outside the gridview and the templatefield with its correct data reappear again.
I already put a variable inside the rowcommand to see if the number of columns are the same with the number of columns the gridview render together with the dynamic templatefield during debugging and it is there but cannot render that templatefield in the client.
I have a gridview with checkboxes going down the side for each item. Some are enabled and others are not. At the top of the page is a checkbox which when checked will make all the checkboxes on the side enabled. THis is not working and I have tried 2 variations. What am I doing wrong?
