Forms Data Controls :: Access Values Of Dropdownlist Of DgChildren Inside DgParents?
May 12, 2010
I have a datagrid "dgParents" and inside this datagrid I have another datagrid "dgChildren".
In dgChildren I have three dropdownlist drp1, drp2, drp3.
I have a button"Save"
I am able to populate data.
Now User selects any value from dropdownlist of dgChildren and click button "Save".
I have a function in code behind for button click here I want to access the values of drpdownlists that are in dgChildren so that I can save in thesevalues in db.
I'm not able to acess the vlues of dropdownlists that are in dgChildren.
I tries findcontrol and controls etc but didnt work.
I'll really appreciate any help for sample code/tutorial/.
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
how I access /retrieve values of checkboxlist inside a repeater? My code is below..is it the same as if it was not inside a repeater? My other concern is how do I distinguish these checkboxes because basically what 's going to happen here is based on which checkbox is selected I need to query an xml file to get the location of a folder which I'm then going to zip up and allow user to download..So here's the breakdown. I have an accordion panel using jquery ui. Each panel hold a product and each product has the same checkboxes..so depending on which product the user wants to download files for which he/she will indicate by opening the accordion panel for that product and checking which checkboxes/file they want to download . So how will I know which product the user clicked the checkboxes for being that I'm using this repeater which just one ID?
[Code]....
can I still use this code or will it not work cause it's inside a repeater..also I was going to use jquery to add an onclick event to the checkbox so how can I do that now with me using this control?
[Code]....
Here's another issue..I can't even assign values to the checkboxlist using databinding..so how am I suppose to do this.. Server Error in '/ArchitectView' Application. Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.ListItem does not have a DataBinding event.Source Error:
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 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:
I have a ObjectDataSource and a ListView referencing it.
I have created a Templated User Control (see: http://msdn.microsoft.com/en-us/library/36574bf6.aspx) and placed it in the ListView's InsertItemTemplate It has one template <ContentTemplate>. Inside that template, I've defined a couple of server controls with their properties = '<%# Bind("colName") #>'.
I need the ability to check a box and then store or remove the text of the checkbox clicked to my sql server database. see my code below that is written in vb.
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="SBN_Company_Cat_Types.aspx.vb" Inherits="ShopBuyName_Test_Site.SBN_Company_Cat_Types" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
I have gridview in my page that users can edit their data in gridview... and in this gridview I define label that I want when users click on Edit button it change label3.text:
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.
I'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]
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 list of addresses and would like to bind ZIP Id to DropDownList.
when I use SelectedValue property it throw the error: 'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value.
I am new to ASP.NET, trying to learn it. I am using ASP.NET 3.5 with VB for scripting. Also read some books. I just can't figure out how to bind a DropDown List inside a Repeater Control. I saw a few examples but none were clear enough and explained all the details. I want to populate the Drop-Down using values from a Database inside the repeater.
I also read this article [URL] but still can't understand how to bind dropdown in a repeater.
I want to display 2 things inside the Repeater Control.
1. User Selected Values (which comes in the form of an Arraylist) from a previous page using "PostBackUrl" method.
2. Then allow users to select values from a Dropdown list corresponding to each design code they selected on previous page. (the dropdown values here must come from a backend db)
Also, I want to control the number or rows displayed inside the repeater control. It should be equal to the number of "design codes" selected by the user on a previous page.
I'm trying to bind a value to a dropdownlist. Here how the code looks like in the aspx page...Bind the textboxes below is not a problem...but its not working with the dropdownlist..
So basically, what i want is the value selected from the dropdownlist to be remembered after i press next button and back button..
I have a dropdownlist which gets the data from the oracle database, the values that contains quotes example "Apple's" or "Website's" or not getting seelcted from the list except these values remaining values have no issues.
