Forms Data Controls :: Can Retrieve Values From A DataList
Apr 26, 2010
I have a datalist that is bound to a table in the database. I need to have a button for each item. Then, when users click that button I want to be able to retrieve information about that item. I have done this with gridview, but cannot seem to get it to work with a datalist. The only reason I am using a datalist is because I am able to arrange the items how I want and not be forced to have columns.
Updates to the edited item are not passing the new / updated values but rather the original values. And I can't for the life of me figure out why when I change the original value in an edit textbox and post the update the new value is not being passed. I get the original value. Perhaps fresh eyes can spot the problem. This should be super basic but apparently I'm missing something.
Here's the code for the Item and Edit templates. The code behind is below this.
I have data in mydatabase. My AnswerText in the database is test1,test2,test3 While retrieving it is displaying as test3,test1,test2. I am using the below code to display the data.
Dictionary<string, string> dicKeyValues = new Dictionary<string, string>(); for (int i = 0; i < cnstsData.Answer.Count; i++) { dicKeyValues.Add(AnswerText, AnswerImage); } DataList.DataSource = dicKeyValues; DataList.DataBind();
I want to display the AnswetText as test1,test2,test3. Basically i want the same order which i added to the database while retrieving also.
I'm populating a dropdown box bound to an sqldatasource. From the sqldatasource, I'm retrieving locationID,locationType and LocationName.
The locationName is displayed in the dropdown. The selected values is set to, "locationID'. Based on the 'LocationID' the user is directed to a new page.
However, I need to pass the "locationID" and also the "LocationTYpe" values for the selected Name, so the sure can be directed to a specific page..how do I get BOTH values, 'locationID' and 'LocationType' when the user selects 'Location NAme' from drop down.
The method has a return type of collection<businessEntity>, i am calling the method from the aspx page in order to populate a drop down -> ddlDropDown. I am binding he DataTextField of the ddlDropDown with the BusinessEntity.Name and the DataValueField with BusinessEntity.Id, the business entity contains another id which is BusinessEntity.ProductId. I need to use the ProductId of the value selected in the drop down list in the code behind.
One possible way could be to call the method in the page_Load on the code behind and save the collection in a hidden variable and when required do a loop through in the hidden variable and retrieve the selected value Product Id.
I am coding one project for my last year project. In this project i have code for seat selection logic. In this I used datalist control and one image button control inside template field. I want to code like,,,
when I do click on this image button i want to send this buttons's alt text in DB as seat no. but I could not code for same.
code this or do you have any another logic for seat selection in asp.net code?
am using C# .net.. in my page am having nested repeater control.. in child repeater there is check box and a hidden ID. i want to store(here am get strucked) the ID of checked box in to my data base.. look at the below code..
Anyways i am having some serious trouble with a datalist. im sure it is probably pretty easy but im am just not very good at all with the codebehind. Basically i have a datalist connected to sqldatasource and it pulls a list of items. I want to be able to select a record from the datalist and store that value in some sort of shopping cart.
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.

I want to retrieve and store(in an array) all the row values of a particular column in a gridview..i.e,if I have gridview with columns col1,col2 and col3, I want to retrieve rows of col1 by specifying col1..And,store all the rows in an array
I have a datagrid whose columns are autogenerated (based on the results from an SQL SELECT query). However, I need to retrieve values from certain cells across the datagrid, using the following code to step through the results.

I need to specify all my columns using TemplateField?
I am new to using ASP.NET and I am using a datalist to represent the data obtained from querying a database.However,I am facing 2 issues:
1) If the string returned after querying the database is too long,the datalist is displaying the long string as it is which is not looking good.I am using Eval to fetch the data from the database for the sake of displaying.I need to have some page breaks so that the information fetched is presentable.
2) While repeating the datalist I want to hide all the columns except for 1 column whose value are unique.Upon searching I found this link: http://www.programmingknowledge.com/DataList.aspx but the code is in VB and I am not familiar with it.I am familiar with C#.
I am inserting the front end code for my datalist.I also want to know if datalist is the best control to present the data from the database.
I have a datalist menu that has several menuitems in it(each item load user control).I want to show each menuitems in seperate dynamic Ajax tabs when I click on first item tab is created but when I click on second menuitem to create second dynamicajax tab I faced this error:
I have one checkbox control in Datalist Header and some controls in Item Template. On click of the "Submit" button in the page I should capture the state of controls from Datalist.For Item template I can get the values from datalist.Items property.How can I get the state of checkbox in "Header Template"?
I have One DataList in their three columns ID, FirstName and LastName, when I select ID then I want to access the value of ID how to get the value of selected ID.
I use a ModalpopupExtender to show a dialog to the user which consist of a CheckBoxList control that is bound to a session table. The user can check/uncheck the CheckBoxList items and click the Ok control to close the ModalPopUp. How can I retrieve the values of the CheckBoxList items controls using JavaScript (seems like I cannot do it using server side scripting)?
The problem is that i have a search page. Access Database holding the information. I have a Access Datasource on the page with a Datalist to show the data. I need to find a way on setting it up to says "Sorry no results found" when the is no results. i am unsure on how to do this though.
