View 1 RepliesI want to create a drop down list, where user can view the code name and the name the code when they click on the drop down list.
But after they choose, only the code is appeared. This is my current coding as for now.
<asp:DropDownList ID="ddlcodetype" runat="server">
<asp:ListItem Selected="True">-</asp:ListItem>
<asp:ListItem>DK Deck</asp:ListItem>
<asp:ListItem>EG Engine</asp:ListItem>
<asp:ListItem>CT Catering</asp:ListItem>
<asp:ListItem>OT Others</asp:ListItem>
</asp:DropDownList>
With this, both my name and the code name are appeared.
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

View 3 RepliesI have a listview control which is bound to DataTable object. When a user clicks "Add", I am creating a new row in the underlying datasource and refreshing the datatable so that it includes the new row and displaying the listview. My requirement is to "select" the newly added row after listview is refreshed. I have the ID of the newly created row and it is bound as one of the columns in the datatable.Now my question is, how can I get the index of that particular row which was newly created from the Listview so that I can set its SelectedIndex.

View 3 RepliesI have a column in SQL Server 2008 called MapLocation which is stored as the geography data type. This column is used to store the location of a building in one table, and the location of landmarks in another table. I have to list all landmarks within 4 miles of a building.
I have a clustered primary key on an automatically generated int column in each table. I assume that I need to create a spatial index on the MapLocation column in the landmarks table. This I guess would aid finding all landmarks within 4 miles.
My problem is that I am not sure what settings to use for this spatial index. I have set the spatial index to have the following settings:
Cells per object: 16 Level 1: Medium Level 2: Medium Level 3: Medium Level 4: Medium Tessalation Scheme: Geography gridAre these the best settings? Am I doing the right thing?

I want to get the value of the specified index in a DropDownList
View 1 RepliesI've made a small site which purpose is to allow people to add members to their clan. The page has a dropdown list with the names of all available clans.
The name of the clans and the clan password come from a text file which is read when loading the page (but not when there's a page postback) and adds the clans to the dropdownlist.
The clan name and clan password are also read into an array for later use.
When the user selects an item in the dropdownlist I want to get the index so I know which clan name to use and which password.
I tried getting the index by using the indexchanged event and also just the click event of a button but somehow this doesn't seem to be working properly.
When the user filled in all fields and hits the submit button I want to check if the password is correct and want to know the clanname. I'm trying to do this by using the array's with that data and setting the item of the array equal to the index of the selected item in the dropdownlist.
But when I press the button I keep getting a wrong password error even though it's correct. If I remove the password check and submit it then the form should create or append to a text file with the name of the clan. But when submitted the text files is .txt instead of clanname.txt.
Tried setting the dropdown to autopost back or without and get the same result.
My code is the following:
reading the data into the array + adding the clannames to the dropdownlist
vb Code:
Dim data() As String Dim clanname(50) As String
Dim clanpass(50) As String Protected Sub Page_Load(sender As Object, e As System.EventArgs)
Handles Me.Load
Dim fileName As String = "C:/ClientSites/data/clans.txt"
[Code] ....
The submit button code
vb Code:
Protected Sub btnSubmit_Click(sender As Object, e As System.EventArgs) Handles btnSubmit.Click
naam = txtMemberName.Text.ToString gamertag = txtGamerTag.Text.ToString
platform = txtPlatform.Text.ToString index = DropDownList1.SelectedIndex
paswoord = clanpass(index)
[Code] ....
In short I load in data from a file into two arrays, clanpass and clanname. Populate the dropdown with the clannames. Then upon submitting I want to check the password against the password for the selected item by using it's index. I also want the name to write it to the correct text file.

i have 2 drop down list on my web page
-the first one bound to a sqldatasource and it's work fine
-the second one bound to a sqldatasource (with a parameter depends on the first drop down list selected value )and it's work fine too .
But when a user make a selection on the second drop down list, any post back on the page will return the second drop down list selected index equal to 0.I tried so hard (ON MSDN) to understand why this happen only on this drop down list.
I am having the code for selectedIndexChanged event of a DropDownList in Asp.Net that looks somewhat like this

I know that I can acheive the same objective by tweaking the code a bit, But I am more imterested to know if .NET provides any such implementation.
I want to compare each item in a dropdownlist to a value and if the item matches the value, I want that ddl list item to be 'selected' and showing...
why doesn't this work:

Im working on an ASP.Net web forms application, where I have a form and the Index is working correctly, until I select a value from one specific control, a dropdownlist. After that no matter what control I am on if I press TAB it will go to the URL/Address Bar, from there to the search bar and then again to the URL bar...
View 1 Repliesi have a user control that includes a dropdown list its actually a page navigator when the user press next page iam setting the index of the selector to the value of a hidden textbox where textbox is filled from javascript function. ex txtbox initially is 1. then when next pressed it is 2 and so on but when doing postbacks i.e pressing next it is not changing the index although in the debuy its showing its setting to the new value. as if there is something that is reseting it to the initial value after the page loads if i put my method in the prerender method its working fine. but in the page_load method its not updating to the new index changed. i need to put it in the page_load method as i have to register some event handlers for the navigator.
View 5 RepliesI have Created A Custom Control which is a DropDownList with specified Items. I designed AutoPostback and SelectedCategoryId as Properties and SelectedIndexChanged as Event for My Custom Control. Here Is My ASCX file Behind Code:
private int _selectedCategoryId;
private bool _autoPostback = false;
public event EventHandler SelectedIndexChanged;
public void BindData()

But Always The Selected Index of CategoryDDL1 is 0(Like default). this means Only Zero Value will pass to the event to update textboxes Data. what is the wrong with my code? why the selected Index not Changing?
I am using SelectedIndexChanged in the DropDowList and it works fine and populates a GridView based upon a site selection.
Is there there a way I can reset the SelectedIndexChanged so if user wants to refresh the GridView they would open the drop down list and click on the same selection again?
I am populating a DropDownList from a text file (class requirement).
The file is read in the Page_Load method and the DropDownList is populated then.
When I press the Submit button, throughout the process of the code it is supposed to get the SelectedIndex and use it to grab a value out of a List(Of ).
The thing is, nothing is ever passed through. I even setup an alert box and it passes right over the alert box and never even triggers it, but gives me an Index out of range error when it moves to the line right after the Alert.
