View 1 RepliesI am trying to use j-query autocomplete but i am getting this error: "The name 'txt_UID' does not exist in the current context" ..Â
I am using the code but the example I was following uses a text-box that was outside of the gridview. But my textbox is inside the gridview. Â
How can I make the autocomplete to work a text-box that is inside gridview? Â
-- Here is my javascript
<script type="text/javascript">
$(document).ready(function () {
$("#<%=txt_UID.ClientID %>").autocomplete({
source: function (request, response) {

In the example below I have set the control style to 'controlName' I want to use this class to define what my textbox looks like in edit mode. This works ok, so far so good. The Problem In a button event I add the class "validationError" to this textbox if the data is incorrect. When the grid gets rendered I expect to get 'controlName validationError as the class applied to the textbox. Unfortunately, it seems that the declarative statement overrides this and simply ends up as 'controlName' how I can intercept the application of the declarative class so that I get what I desire here?
<asp:BoundField
DataField="Name"
HeaderStyle-CssClass="headerName"
ItemStyle-
CssClass="itemName"
ControlStyle-CssClass="controlName"
HeaderText="Name"
>
</asp:BoundField>

View 1 RepliesI am using a textbox and button to get the user input (account number), this will be used as input to a data access class object (SQL) when the button is clicked. This action should populate the Formview control. I have bound the Formview control to the SQLdatasource and configured the SQLdatasource control to the textbox.TEXT property. What am I missing? What do I need to add to button_clicked event to get all this to work? One other thing, the textbox is in a table area separate from the formview control. I have each of the templates inside of the formview control in tables. The input textbox and button are displayed but the formview control is not, all of this is in a master/detail object.

View 3 RepliesI have a drop-down list that is wired up to a datasource from one table to retrieve a Vendor ID and Vendor Name. This ddl is outside a FormView that is wired up to a datasource containing Vendor contracts.
When I choose a Vendor from the ddl, I am able to populate a textbox outside of FormView with the Vendor ID from the ddl. However, what I need to do is populate a textbox within FormView with the Vendor ID. FormView is in Insert Mode by default since my page will be used for Adding Contracts only.
I would like the user to select an item from a drop down list. Next to the drop down is a textbox or label control. From the ddl selection I would like to populate the textbox or label from a database with a corresponding field from the database the dropdownlist was populated from. On selectindexchange event I can populate the textbox with the Unique id from the value, but I need to input a different field into the textbox. Can I use some sort of variable to assign the Textbox.Text = ?
