View 6 RepliesI have an UpdatePanel with a GridView. This GridView has a template column that is a DropDownList. The problem is that the SelectedIndexChanged event does not fire for the DropDownList. Here is the code:
[Code]....
The codebehind:
[Code]....
I have a gridview with some boundfields and a template field that contains a dropdownlist. I am trying to populate the dropdownlist with dateandtime values using code behind, but I get an error of Object refference not set to an instance of an object and I don't understand where I go wrongProtected Sub GridView1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.Load
Dim ddl As New DropDownList
ddl = GridView1.FindControl("ddlShippingDate")
ddl.Items.Add("11/11/2010 12:00:00")
End Sub
I am creating a gridview with 1 dropdown(Item),1 label(rate),2 Text bob (quantity,total amount).problem is that dropdown and label access records from one database table.on the basis of dropdown selection item rate label display rate of that item.then user insert quantity and amount calculated base of item quantity and rate. and row is autogenerated or by command button for other item.
View 3 RepliesI've seen several examples here but for some reason I still cant get this to work. I have a gridview of user information.
userid name phone role
00001 john 12345 [downdownlist]
00002 jack 12345 [downdownlist]
00003 jeffz 12345 [downdownlist]
00004 jims 12345 [downdownlist]
The code would look something like this:
<asp:GridView
ID="gvUsers"
runat="server"
AutoGenerateColumns="False"
DataSourceID="dsUsers"
DataKeyNames="id"
[Code].....
So as my example code above shows, I'm trying to build a dropdownlist within the gridview. The datasource for the dropdownlist is based on the userid. The two datasources (dsUsers, dsRoles) are two different tables in the database. HOw can I implement the dropdownlist to use the userid from the gridview to query the dsRoles to populate its list?

I have a GridView, the first column it's a RadioButton template and the second it's a DropDownList Template, the number of rows depends on the user, I mean they are not static. I'm using the following JS function to get the row selected with the radiobuttons:
[Code]....
With this function I know which RadioButton was selected, now, I would like to get the DropDownList value or text of the selected row, I know I have to loop through every DropDownList to get an array of controls, but since they are something like ctl00_ContentPlaceHolder1_GVProducts_ctl02_DValsDropDown, I just don't know how to achive this through JS.
I need to generate a GridView and inside of one of the cells insert a DropDownList.
The GridView is a list of the users of the web application.The DropDownList is a list of roles of the web aplication.
The GridView is to be a table with the diferent users, diferent columns with various information, the last cell should have a DropDownList with the roles, the role which the user of the line belongs to, should be visible!
I have a gridview which contains a templatefield. Inside this is an ImageButton and a dropdownlist. This is all created in the aspx page, although the ddl list items are populated in the RowDataBound event in the vb page. When i change the selected item in the drop down list and hit the imagebutton, the selected item is not maintained after postback. Instead the first record is displayed in the dropdownlist. I have wrapped an If Not Page.IsPostback around the datasource and databind's but this doesn't help. I have tried enabling viewstate in all areas on the page too, but still nothing. The list items for the ddl must be created on RowDataBound also. As far as I am aware, my ddl is not really dynamic, its just the list items which I add in the code behind which are classed as dynamic.
View 11 RepliesI am having Gridview ie : inside i have placeholder, So on Gridview_RowDataBound - according the Specific Condition getting from DB then - i am Creating the Dropdownlist dynamically here and assign Datasource. so up to this its ok.

I have 2 dropdownlist(ddlCategoryFooter and ddlItemCodeFooter)inside my gridview. I want to set ddlItemCodeFooter 's datasource to my getItemList(decimal categoryID) method. The selecteditem of ddlCategoryFooter will serve as the paramter which will be passed to my getItemList Method. Basically,ddlItemCodeFooter is dependent on ddlCategoryFooter's selectedItem.
I know it can be done in code behind approach but i prefer to place it in my asp page.
This i what i want to acheive:
DataSource ='<%# getItemList(Convert.ToDecimcal(ddlCategoryFooter.seletectItem))%>'/>

I want to add dropdownlist in gridview n connet it to one of my database column how can i?
View 1 RepliesI have a GridView with two templatefields, one with a DropDownList and the other with a TextBox, both loose their values once I hit the "update" button. Is it any way I can make the controls keep the values?
View 8 RepliesI have the following (abbreviated) code:
<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.
I have a listview that is showing its result by using a linq query. The linq query goes like this.
[Code]....
* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.
[Code]....
And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):
[Code]....
I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these
