I have three drop down lists that are all databound to a gridview. When the user selects 1. a school, 2. a house number, and 3. a street from seperate drop down lists, bus stops for that address are displayed in a gridview. Everything works fine. After the user selects a valid school/house number/street combination the gridview automatically displays. I would like to add a "Submit" button and not have the gridview display until this button is clicked.

View 2 RepliesI have a page with multiple textboxes and each has a button associated with it. This works as a search 'hub', I suppose, where the user can search by ID, name etc. When entering a search term for e.g. name however, pressing enter 'clicks' the very first button on the page (ID search), causing an error if the associated textbox is empty (which it would be if someone meant to search by name). I have attempted to rectify this using JQuery, and have written the following:
$('input:text').click(function (e) {
e.preventDefault();
$(this).next('input:button').focus();
});
I'm simply using the click event so that I can monitor where focus is redirected, but eventually I would use .keypress. However, nothing happens upon clicking a textbox and I can't see for the life of me what is wrong with the JQuery. To elaborate on the problem, the .NET code used looks similar to the following throughout the page.
<tr>
<td style="width:100">Company ID</td>
<td style="margin-left:3px;">
<asp:TextBox ID="...TextBox" runat="server" Width="230px"></asp:TextBox>
</td>
<td>
<asp:Button CssClass="Button" ID="...NameSearch" Text="Search" runat="server" /></td></tr>
This is generating this (view source):
<td><input name="...TextBox" id="...TextBox" style="width: 230px;" type="text"/></td>
<td><input name="...NameSearch" class="Button" id="...NameSearch" onclick="javascript:__doPostBack('...NameSearch','')" type="button" value="Search"/></td>

View 4 RepliesI have a modal popup and a GridView in it. The GridView is populated programmatically, i.e. I use .DataBind(). I can enter data into some of the GridView's controls. After I press Submit, I expect to do something with the entered data. But in the button press handler, the GridView is empty. I realize that I have to DataBind() again in the handler, but how can I preserve the data the user enters?

After selecting one item from the radio button, the drop down list below fetches values from database and is refreshed. I choose some value in the dropdown list and submit the form.

I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:

Have a dropdown list with autopostback set to 'yes' have another dropdown list box that will be populated based on the selection of the first dropdown. It works fine until I put a submit botton on the form. When I do it appears to not do the auto postback until the submit button is pushed. Can you have a submit button on a form that has a dropdown with autopostback active.
View 2 RepliesI have a dropdown list which is in updatepanel. I have to fill that dropdown on a client event through javascript which calls __dopostback of the updatepanel and calls its load event.
Problem is that when i submit the form updatepanel_Load event also execute again and it again reset the DropDownLIst which causes the loss of selectedValue in Dropdown.
<asp:UpdatePanel ID="UpdatePanel3" runat="server" OnLoad="UpdatePanel3_Load" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="ddlItems" runat="server" CssClass="dropdown">
</asp:DropDownList>
</ContentTemplate>
</asp:UpdatePanel>
On page Load this dropdown is Empty .... no funtion to fill it.Now the problem is when ever I Fill the Dropdown throught Load of UPatepanel, that UPdatepanel Load event also execute when I submit my page. Actually the solution of javascript is due to a table and on Selection of the table row item it Fills the DropDownList from __dopostback of my updatepanel.
I have button which opens a popup window and that popup window contains a table, when client select some item from that table and close that popup window then I fill my dropdown (in parent or opener page through Ajax, Updatepanel's Load) as further selction option. so dropdown databind is dependent on that tables input.
