C# - Dropdownlist Shows Duplicate Values While Editing A Row In The Gridview?
Jan 11, 2011
Well the dropdownlist has an existing items. I just want the selected gridview record to be displayed in the dropdownlist. The dropdownlist has several DataTextField in string and consist of DataValueField in numeric. The gridview passes a string text to the box which has an equal or same item inside the dropdownlist. Whenever i passed a record from a gridview to be viewed in the dropdownlist it just duplicates the same item. Q: How can i simply pass a text inside the dropdown and just simply display it without adding on the list.
sample item on the dropdown:
--Select--
Account
Savings
after selecting on the gridview and display inside the dropdown:
Account
Account
Savings
(you see the '--Select--' was erase and replace with the selected record)
I have hard coded and added items to dropdownlist ie teamsize as 1,2,3 like that.When i load this dropdownlist for edit/update i get duplicate values like this
I have a master table relationship, i.e. depending on what is selected in the dropdown list the grid show the relevant data.In the database there are several identical entries for the Position field, for instance there are four marketing managers that have different name. How can i group the identical Position name in the dropdown and when selected the grid should display all marketing managers. Here is the code:
i am making an application using a datagridview... And I am very new to it. And I need to edit my datas in gridview using a dropdown list.
So this is the flow of the program. As the page load, my gridview will appear, with the datas from the database binded to it, so far I have done that already. Every row in the gridview has an edit hyperlink, so when I click that, I can change the values in that row using a dropdownlist, wherein, the item in my dropdown are aswell from my database.
The user will enter values in the textbox of the gridview in item template. A button outside the grid, when it is pressed we have to highlight the duplicate values.

i have followed same steps just but difference is i have a edit imagebutton with commandname="Edit".Also dropdown needs to be binded from different table(directory) and not the table through whicch grid is binded(details).
if (e.Row.RowType == DataControlRowType.DataRow && (e.Row.RowState & DataControlRowState.Edit) == DataControlRowState.Edit && GridView1.EditIndex == e.Row.RowIndex) { DropDownList DStatusEdit = (DropDownList)e.Row.FindControl("DStatusEdit"); string query = "select distinct status from directory"; SqlCommand cmd = new SqlCommand(query); DStatusEdit.DataSource = GetData(cmd);
[CODE]..
the page is running but when i click edit image button the dropdwn shows but no data in dropdown binded it is empty.
My gridview is inside update panel.
How can i achieve this?
Should dropdownlist in my case be binded inside rowcommand and how?
On Edit Click, the DropDownList in the GridView brings the previously selected value.On Update Click, the error is: "System.FormatException: Input string was not in a correct format."
ddlRegionNavn.DataTextField = "RegionNavn"; ddlRegionNavn.DataValueField = "RegionID"; // from RegionNavn to RegionID
On Edit Click, the DropDownList values in the GridView is not firing and the following error shows.Object reference not set to an instance of an object. How to implement the code when having a value of type Int ?

I'm designing a web page with two dropdownlists, one for the Make of a car, the other for the Model, both bound to a database with separate SQLDataSources, and using a distinct statement. I add "All" at the top of both by setting appendDataBoundItems = true and adding items named all. Then when I fill the Make with a querystring all the model items get added twice (but only the databound items).Here's my code:
<asp:DropDownList ID="DropDownMake" runat="server" DataSourceID="SqlMakes" DataTextField="Make" DataValueField="Make" AppendDataBoundItems="True" EnableViewState="False" AutoPostBack="True"> <asp:ListItem Selected="True" Value="All">All</asp:ListItem> </asp:DropDownList> <asp:DropDownList ID="DropDownModel" runat="server" AppendDataBoundItems="True" AutoPostBack="True" DataSourceID="SqlModels" DataTextField="Model" DataValueField="Model" EnableViewState="False"> <asp:ListItem>All</asp:ListItem> </asp:DropDownList> <asp:SqlDataSource ID="SqlMakes" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT DISTINCT [Make] FROM [Parts]"> </asp:SqlDataSource> <asp:SqlDataSource ID="SqlModels" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT DISTINCT [Model] FROM [Parts] WHERE ([Make] = @Make)"> <SelectParameters> <asp:ControlParameter ControlID="DropDownMake" Name="Make" PropertyName="SelectedValue" /> </SelectParameters> </asp:SqlDataSource> 'And in the VB file: Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init DropDownMake.SelectedValue = Request.QueryString("Make") DropDownModel.SelectedValue = Request.QueryString("Model") End Sub
If I remove the line "DropDownMake.SelectedValue = Request.QueryString("Make")" it doesnt produce duplicates anymore. What is going on?? I swear I've spent more time developing entire iphone app.
I am trying to find out the best method or practice to use a dropdownlist to feed my oracleparameter value. I currently have this working when I have a value selected in the dropdownlist. My issue is how to account for if the user leaves the dropdownlist empty. I want this to then return all data. My SQL has a where clause = to :HRM. I use a function that gets the text for my SQL from a text file. My dropdownlist box is populated via databind. I then inserted a item in my dropdown with 0 index with no text display and a value of "novalue" Below is my code to populate my dropdownlist
[Code]....
[Code]....
If I select an item and run my code it works great. This doesnt work with the no selection tho. Do I have to build the SQL dynamically with a check if the listbox is empty or not and then add the criteria? I was hoping there was a eailer way since I have many queries and parameters to build.
Here is part of my code using the oracleparameter.
[Code]....
I also saw a post about trying this, but I get an illegal error.
[Code]....
Not sure if I can replace the "AND HRM_FIELD = " text and use :HRM instead and then build the oracleparameter with an IIF to include the AND HRM_FIELD part.
I feel so stupid asking this because this used to be such a easy task in webforms. Well here we go. It's on my admin part I got a site called edit, on that site there are a dropdown so I can choose what site to edit, once choosen it suppose to get the site body and put it in the textboxes and keep the selected site in the dropdown, this is all suppose to be on the same site Edit. I'm totally lost on how this should be done. this is the code I got so far in my AdminController, I only populate the Dropdown with Editable sites available.
i have 20 Textboxes i am not sure what did i touch by i normally dont play with VS Settings i dont understand. So those textbox are normally defined like this
I have 2 listboxes, when i add a item retrieved from database to Listbox1, i need to select the item and bring it to listbox2. But i do not want to have same records added again. In my case, i cannot use the codes below
[Code]....
because the text displayed on listbox1 and after transferring to listbox2 are different. So i come out with a logic which is "if listbox2 does not contain the item value in listbox1 then populate listbox2". So i tried the codes below, but it is not working as there are errors
I am making a crystal report which displays values from database. Now the values from db contains duplicate values. I need that duplicate values should be suppressed and should display 0.00
Value 250.00 250.00 250.00
Should display 250.00 0.00 0.00
I have applied "Suppress Duplicate" to the column but don't know how to display 0.00 there.
I am using SQL Server2005 with asp.net. I want validation at server side to restrict duplicate entries, Here i am using two tables companies and Branches. In Branches Table i had maintain a foreign key of CompanyId. In Branches the BranchName can be duplicate but not for the Particular CompanyId
