C# - Bind The Values Without Duplicates From Database Into Dropdown Using LINQ?

Apr 2, 2011

I have a small issue binding the values into a dropdown using LINQ in ASP.NET code-behind.

var clientquer = from i in Entity.New_Bank select i;
//var q = (from s in names
// select s).Distinct();
// var getlendername = (from db in mortgageentity.New_Lender group db by db.Bank_Name into t select t.Key).ToList();
if (clientquer.Count() > 0)
{
ddlbankname.DataSource = clientquer.ToList();
ddlbankname.DataValueField = "Bank_ID2";
ddlbankname.DataTextField = "Bank_Name";
ddlbankname.DataBind();
}

It is binding with duplicate values, but I don't want bind duplicate values. I'm trying to solve this by using a group by clause, but it is not working.

AJAX :: How To Bind Textbox Control To ComboBox/DropDown Control

Jul 12, 2010

I am using AJAX ComboBox control (or I can use simple ASP.NET DropDown Control it does not matter) in my form. What I do is, I bind combo box control to my database and retrieve client names:

[Code]....

But here is the problem. I want First and Last names to go into separate TextBox controls (txtFirstName and txtLastName). Now it inserts Last Name and Firts Name in txtLastName control. At the same time I would really like to keep LastName + FirstName together in Combo Box.

AJAX :: ComboBox Input / Whenleave The Combobox It Adds To The Combox List?

Dec 3, 2010

I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).

I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.

VS 2010 - When Selecting Default Option For Combobox 1 / Second Combobox Is Disabled

Jun 13, 2012

I have a problem with CascadingDropDown... I have two related comboboxes, where the second is a slave of the first (e.g. country the first, cities the second). What I want is that if I select one country from combobox 1 then the second must be "filtered" by that selection (it should display all the cities inside the selected country, and the actual CascadingDropDown implementation is OK), but if I leave the combobox 1 in the default option (e.g. "Please select a country") I want the second to display all the cities I have in the database. The problem is that when selecting default option for combobox 1 the second combobox is disabled and a postback to my webservice never occurs.

How To Validate Inserted Items In AJAX Combobox Against Database

Nov 30, 2010

I wonder how to validate if a inserted item in a Combobox exists in a database during postback? If the item.text exists, a errormessage should notify the user that the item already exists in the database. If the item does not exists in the database a inserting should be done.

Should i use the customvalidator and create a servervalidationfunction that searches my databasetable for the item name?

Should i validate inside one of the two ComboBox control events, ItemInserting and ItemInserted?

After validating the existence i would like to validate if the inserting to the database was successfull.

VS 2015 - ComboBox Click To Refresh Another ComboBox

Jan 19, 2016

How do you refresh a combo box from clicking on something from another Combobox (using Visual Basic).

I don't want to use a button for this as i know it works that way by using .Databind() on the other combobox.

In access it is so easy by using the click event on a combo box but visual studio does not seem to use it.

SQL Server :: Select SubQuery / Bind Two Values Into One?

Feb 25, 2011

I have a SELECT query which grabs data from two different tables however when I run the query the CurrentCallOwner often pulls up the same name twice albeit with a different SLAFailed value. What I am trying to do is bind those two values into one. I thought that running a subquery and using a count would solve this however I all receive are a bunch ones. Do you know how I could bind those values into a single value (i.e. add them up?)

SELECT CurrentCallOwnerx, SLAFailed, COUNT(CurrentCallOwnerx) AS Expr1
FROM (SELECT BSFLBWF_1.CurrentCallOwnerx, COUNT(BSFLBWF_1.Incidentx) AS SLAFailed
FROM .SRFILE INNER JOIN
BSFLBWF AS BSFLBWF_1 ON BSFLBWF_1.Incidentx = SRFILE.SRONUMBER
WHERE (SRFILE.SR_GROUP = '38') AND (BSFLBWF_1.KPIFailx = '1') OR
(BSFLBWF_1.SchoolChargex > '0.00') OR
(BSFLBWF_1.LANMLEChargex > '0.00')
GROUP BY BSFLBWF_1.CurrentCallOwnerx
UNION
SELECT BSFWES_1.CurrentCallOwnerx, COUNT(BSFWES_1.Incidentx) AS SLAFailed
FROM SRFILE AS SRFILE_1 INNER JOIN
BSFWES AS BSFWES_1 ON BSFWES_1.Incidentx = SRFILE_1.SRONUMBER
WHERE (SRFILE_1.SR_GROUP = '38') AND (BSFWES_1.KPIFailx = '1') OR
(BSFWES_1.SchoolChargex > '0.00') OR
(BSFWES_1.LANMLEChargex > '0.00')
GROUP BY BSFWES_1.CurrentCallOwnerx) AS derivedtbl_1
GROUP BY CurrentCallOwnerx, SLAFailed
