C# - Clearing Text Box / Text Changing
Aug 12, 2010
I have a scenario whereby I have a textbox with an autocomplete extender attached and two drop down lists; this enables a user to search for product info. Ideally I'd like to create something that effectivley, 'resets' the drop downs so that when a user clicks on the textbox (maybe I'll do it 'onenter'/'ondelete' if there is such a thing). I've had a look at .Attributes.Add but cannae figure it out. How do you include asp.net controls within this scenario so I could have something along the lines of:
tbxAutoComplete.Attributes.Add("OnClick", ddlLevelAuto.SelectedIndex = 0, ddlItemCategory.SelectedIndex = 0,);

I have a page with a text box, a button and a GridView. Enter an account number in the text box, press the check button and the result will show in the GridView.
Now user wants that if the text box is clear, the GridView disappear.
I can only find TextBox1_OnTextChanged. But I want to have that while the user is clearing the text, if the length of text becomes zero, the GridView is clear out. So I am looking for OnTextChanging(). Well of course this function does not exist. How to achieve the same purpose?

I have a ddl that controls the visibility of a textbox (using panels). For example if i select 'Other' from the text box, a post back occurs and a text box appears beneath it for you to give further details. If any other value (for example 'dry') is selectedit's an accepted value and nothing else happens. Only problem is that if i select other, add details the text box and then go back and change the value to 'dry' (for example) the text box may dissapear but the value is still held within the box

Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene

I have a dropdownlist, and a Gridview where one of the columns is a dropdownlist. both dropdown lists use the same data source. When a value is selected in the dropdownlist (outside the gridview) I want to chaneg the selectedValue and selectText of every dropdownlist in my gridview. This is what I have tried:
Dropdownlist:
<asp:DropDownList onclick="javascript:onJDSelection()" ID="DropDownList3" runat="server"
DataSourceID="SqlDataSource4" DataTextField="circt_cstdn_nm"
DataValueField="circt_cstdn_user_id">
Javascript:
<script type="text/javascript">
function onJDSelection() {
var jd = document.getElementById('DropDownList3.ClientID').selectedText;
var grid = document.getElementById('GridView2.ClientID');
//Loop starts from 1 because the zeroth row is the header.
for (var i = 1; i < grid.rows.length; i++) {
var OtherText = grid.rows[i].cells[2].innerText; // Works fine
grid.rows[i].cells[3].getElementsById('ddl_JD').selectedText = jd;
}
}
When I click I get an error. It says object expected. However I know those objects exsist!

I am currently designing a multi-tenant website where many clients will share the same code base but have their own "look-and-feel" to the site when the are logged in. This is nothing new, but I am looking for ideas on the best way to implement the solution using ASP.NET and MVC3 (which looks awesome).
The main thing I am looking at now is how to change the CSS style-sheet and text for the labels and static portions of the pages per client. So this would be something like localization where I would want to just have a string in the Razor template, like @FirstNameLabel and then at runtime it would grab the specific value setup for the logged in client for that variable.
I know I could implement this with a database, but I am just making sure there isn't some clever way to do this in .NET (I have been in the Java world for several years now). It seems like I could possibly use a variation of localization or globalization with ResourceManager, but I haven't found any examples that were not based on cultures, which I do not want/need at this time.

What would be the best way of going about doing this;
On my website I am putting some short stories in and allowing people to change the name of the characters in the story to match their own. I was going to keep the stories in a SQL DB but not quite sure how I would go about changing the names of the characters dynamically?
Would I be best using say (Name1), (Name2) etc in the stories in the DB then changing it using a string query on the code behind or is there a better / quicker way to acheive this?

I have a asp:listbox with 5 items in it. By default the list box is disabled. (i.e it only shows the items in it but user cant do anything with these items.) I have to make the color of these items in the list box to red but when the listbox is disabled the items are defaulted to the gray color. Any idea how I can change the color of the items in the disabled list box ?

I have a single event handler for multiple buttons. By default, the label says player 1 and when a button is clicked, the label changes to player 2. How would I go on having it go back and forth between player 1 and player 2 when a button is clicked until one of them wins? Preferably in C#.

The following code is my Grid View AA from aspx page.
<asp:GridView ID="GridView_AA" runat="server" OnSorting = "Gridview_AA_Sorting" OnRowCreated="GridView_AA_RowCreated">
<asp:TemplateField HeaderText="Period Name" SortExpression="PERIOD_NAME">
[code]...
I cannot sort after adding GridView_AA_RowCreated function. Each column of Grid view header-text worked well before I add this Row Created function. If I cut the following code: e.Row.Cells[2].Text = "Period Name";
Sorting works. I want to get sorting without removing this Row Created function. Do you have any brighter solution about my problem?
protected void GridView_AA_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[2].Text = "Period Name"; //Change header text in run-time
}
}
