Forms Data Controls :: Access - Retrieve Values Of Checkboxlist Inside A Repeater?
Jun 24, 2010
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:
I'm having a problem trying to retrieve a dropdownlist value that is located within a nested repeater. Basically I'm trying to create a shopping cart that allows the user to select a shipping method and the shipping method is contained in the repeater. So my page structure looks something like this.
Gridview
[Code]....
To me this should work, but the problem I'm facing is that there are no repeater items. The Items.Count property in the repeater is 0. I am not calling DataBind on the Gridview nor the Repeater before this code is reached (this code is the first thing that happens in my button click event) and my binding is done inside a !IsPostBack statement in my page load. I've made sure databinding is not occurring by setting breakpoints on the code that databinds both the gridview and repeater.
It seems to me like the nested repeater is losing it's viewstate or something on a postback. If that's the case, how can I get the selected value of that dropdown control inside a nested repeater?
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..
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)?
I have a GridView inside a repeater, and for all the GridView events such as ItemDataBound, etc. I can't just use the same because it doesn't recognize it. I know I have to use FindControl and type in the ID, but how?
When user upload new documents then this document goes for approval to supervisor and for this i use dropdowns ...when I use dropdown the exact result not occur and now i wat to approve/reject through checkboxes...
In my code i will get the controls dynamically according to the Family members count.Now i need to display the values of each control individually which are placed inside the repeater control. plz plz go through my code then you can understand my situation.I want to get the values ofxtMemberName,drpRelationship,txtDateofBirth as in my database(dataset) for each control.This is my code:
I have a form with 2 sections. The first one contains some radio buttons. The second one contains a checkboxlist. When we change the selected radio button then it modifies the elements in the checkboxlist. For this I setted the radio buttons with autopostback, and in the code behind (in OnLoad) I populate the CheckBoxList depending on the selected radio button.
This work fine.
The problem is that I also have a button at the end of my form which post the data of my form in another page (with PostBackUrl). Then in that page I would like to retrieve the values of the checked checkbox. But I can't find how to do that. In the Request.Form I don't see anything.
I searched on the web but I didn't found really a solution.
I'm bounding data to repeater control by using SqlDataSource Control
bounded data is something like this:
attributeid attributename 1 color 2 size
How can I get access to attributeid values in Repeater control's ItemDataBound event handler,
I tried to use DataBinder.GetPropertyValue(container,"attribuetid"), but I can't set container, am I doing right, or maybe I should use another approach.
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 am having a form in a view page that looks as below:
[Code]...
Now when the form is posted, I am trying to retrieve the values submitted in the controller as below:
[Code]...
The string value shows null when I submit the form by checking some checkboxes. Is this the way to retrieve the values or am I doing something wrong? And I cannot use html control because all other controls on the form are server controls and I am not sure if I can only make this control a html control. And I am not sure how can I bind the values to it?
I need to access a control inside a repeater and change its properties. To enable it or not. I got an erorr message Object reference not set to an instance of an object. Here is my code inside a method. protected void
rptCAP_ItemDataBound(object sender, RepeaterItemEventArgs e) { LinkButton lnDel = (LinkButton)rptCap.FindControl("lnkDelete"); lnkDel.Enabled = false; //<<<<< this is where the error occur }
I have a button on a page with a Repeater and an ObjectDataSource. To give credit where credit is due, the Repeater's paging functionality is courtesy of ScottGu. (However, I'm using ASP.NET 4.0 and SQL Server 2008, as opposed to ASP.NET 2.0 and SQL Server 2005.)
Anyway, in the button's click event, I need to access the Text property of a Label that's inside the Repeater because it's used as an input parameter in a stored procedure. I'm getting a NullReferenceException when trying to access the Label's Text property. I have researched this error and have tried a few different solutions (involving FindControl and the Repeater's ItemDataBound event), but I haven't been able to get it to work. The code is below.
I have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?
I have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?
what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.
