As you can see I want to pass Container.DisplayIndex to handler. The problem is that this is not just child od ItemTemplate - Button is a child of LoginView which is a child of a Panel inside ItemTemplate ) I found a way how to pass that Container.DisplayIndex: <%# (Container.Parent.Parent.Parent as GridViewRow).DataItemIndex%>
I'm trying to populate the DataPager using Container.DataItem (I'm not allowed to use FindControl) but I get this error
'System.Web.UI.WebControls.DataPager' does not contain a definition for 'DataItem' and no extension method 'DataItem' accepting a first argument of type 'System.Web.UI.WebControls.DataPager' could be found (are you missing a using directive or an assembly reference?)
I have a TabContainer, and one of its tab panels has a user control with a wide GridView in it. Because of some reason, the GridView goes way beyond the size of the tab panel and the tab container. How can I make the tab panel expand based on the width of the GridView?
In my application I have successfully pulled some rows from a database into a DataSet and then used an ASP.NET Repeater Control to create a div container for each row with each field contained within a span element as follows:
My problem is that I want the .png graphic link to have a onclick event so that a new div is dynamically inserted under the div to show data from a seperate database table. However since its all declared within the ItemTemplate then targeting the correct div using the JS DOM would be difficult/impossible as the id for each of the divs will be the same.
If this is going to be infeasible then what is the possibility of having data brought in from multiple tables would I have to manipulate the DataSet to include the extra columns as I think Repeater Controls can only have a single DataSet (corret me if i'm wrong).
I'm working on a questionnaire type application in which questions are stored in a database. Therefore, I create my controls dynamically on every Page.OnLoad.This works like a charm and ViewState is persisted between postbacks because I ensure that my dynamic controls always have the same generated Control.ID.
In addition to the user control that dynamically populates the questions, my questionnaire page also contains a 'Status' section (also encapsulated by a user control) which represents the status of the questionnaire (choices are 'Complete', 'Started' or 'In Progress'). If the user changes the status of questionnaire (i.e. from 'In Progress' to 'Complete'), I need to postback to the server because the contents of the dynamic portion of the questionnaire depend on the selected status.
Some questions are always present regardless of status, and yet others may not be present at all for the selected status. The point is, when the status changes, I have to postback to the page and render the right set of questions. Additionally, I need to preserve any user entered values for those questions which are 'always available'.
However, due to the page life cycle in ASP.NET, the 'Status' user control's OnLoad, which contains the correct status needed to load the right questions from the DB, doesn't get executed until after the 'dynamic questions' user control has already been populated (with the wrong/stale values).
To get around this, I raise an event from my 'Status' user control to the main page to indicate that the Status has changed. The main page then raises an event on the 'dynamic questions' user control. Since by the time this event bubbles up, the 'dynamic questions' user control has already loaded the 'wrong' questions from the DB, it first calls Controls.Clear. It then happily uses the new status to query the database for the 'correct' questions and does a Control.Add() on each. FYI, Control.IDs are consistent across postbacks.
This solution works...sorta. The correct set of questions for the selected status do get rendered; however ViewState is getting lost for those 'always available' questions. I'm guessing this is because the 'dynamic questions' user control calls Controls.Clear when responding to the status changed event. This must somehow kill the association between ViewState and my dynamic controls, even though the Control.IDs are consistent.
This seems like such a common requirement, I'm virtually certain there is a better, cleaner and less error prone approach to accomplish this. In case its not plainly obvious, I haven't been able to grok the ASP.NET page life-cycle despite working with it for the last year.
I have sqldatabase tables.I am reading table data and putting in a tabconatiner(wth tabs containing textbox, checkbox etc) specific to a client. If a client has more than one row i want to iterate through the rows and read each row data. Basically I want to use a button-click to read the next row data at put it in the tabs and so on. I used sqldatareader and a while loop.I can read the data but while loop iterates through the rows and show the last row data / i want to use a button to go to the next row and show data.
SqlDatareader reader=null; reader=cmd.ExecuteReader(); while(reader.Read()) { txtboxName.Text=reader["Name"].ToString(); } protected button_Click(Object sender,EventsArgs e) { //I want to read row data in this button click }
I'm using a third part control suite by Obout. I have a parent grid with two detail grids. One of the detail grids, grid2, has an edit template which generates a custom form. When I edit or add a record, I get the error The OboutDropDownList control 'ddlPosition' does not have a naming container. Ensure that the control is added to the page before calling DataBind.. Only the ddl(s) error. The textboxes, labels and calendars do not error if I comment out the dropdownlists. I'll attach the code.
referring to: [URL] v nice it works.. but i have tried this before in my previous app it works but i just try now <%# Container.ItemIndex + 1 %> but not work ..what is the difrence in these
I am collecting user roles into a single dimension string array.
I have a repeater that its source set to that array. The repeater template includes list of checkboxes for the values in the array.The checkbox text is set to: Text='<%# Container.DataItem %>'
All is good till this point.
But I am trying to call a javascript function triggered by clickign a checkbox and pass it the container.dataitem, but the javascript doesn't seem to be reading the value and either complain about string not being in correct format or that treats the container.dataitem as a liter. This is the trial that didn't work (I tried many different things too):
DetermineVal(<%# DataBinder.Eval(Container.DataItem) %>); determineval is my javascript function
I need to programmatically fill DropDownList in FormView and can't find the proper event to do it. I keep getting "'GenreList' has a SelectedValue which is invalid because it does not exist in the list of items" or "Bind, Eval can only be used in databound control" depending on the event. Sample code follows (there's no attempts to bind a DropDownList there ):
I have created a backend that allows me to update my site content. I am using fckeditor to pull the data from my table in the database. The problem I am having is this: i need to create paging of content so that when the height restriction is met a next btn or numbering system displays to allow the user to click to the next page of content.
I have a FormView with an EditTemplate.And the EditTemplate contains an ascx control:
<asp:FormView ID="fvTicketUpdate" runat="server"
[code]...
The contents of the ascx control has TextBox and DropDownList controls binding to the results of the FormView's ObjectDataSource through Text='<%# Eval("field1") %>'and SelectedValue='<%# Eval("field2") %>'.This works fine and I have been building all of my front end pieces like this as <asp:Panels> rendering as FieldSets that go 100% across the screen.And we call these areas "strips" accross the screen.But now I've run into a problem.One TextBox and one DropDown bind fine to a Ticket Object.But the DropDownList that works has its <asp:ListItems> hardcoded before hand.Now I have DropDownList that gets populated through a WebService in the ascx's code behind like this:
public partial class UserControls_FormControls_PntipUpdtFaaInfo : System.Web.UI.UserControl { protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack)
[code]...
The Problem I think is the FormView is trying to do its Bind to the objectDataSource before its child ascx control is loaded in the Edit Template.And I am getting this error:
Databinding methods such as Eval(),XPath(),and Bind() can only be used in the context of a databound control.Meaning that the control must already be databound to bind the selectedValue to a Property of the TicketObject.Is there an easy way to force the order of loading to make the PntipUpdtFaaInfo control load and have its Page_Load execute and bind ddlEquip before the FormView does its first dataBind and executing its Evals?Otherwise I have to take out the eval on the ddlEquip SelectedValue attribute and go to the Parent Page and hack and force everything to happen when it needs to.This layout has worked out well for me.All of the ascx area strips across the screen share the same Validation Summary for example.It allows me to think about one section at a time and the Properties to the Business Obect and CRUD methods as I go.But this is a big brick wall I've hit.
how can i read child gridview with checkbox here is my code
Protected Sub GridView2_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView2.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then
I enable AutoGenerateEditButton = "true", which can show me edit button in the child grid. Also i have tried to use the event rowediting which can return e.NewEditIndex too. for the master i use sqlDatasource design time. for the child grid am confusing how to do the edit/delete/add.
following link good enuf for master grid
[URL]
for child grid datasource if am not mistaken, guess need to assign the datasource during runtime. am not sure how to do this?
I am currently trying to figure out the best way to handle a data formatting issue. I have a stored procedure that pulls back basically all the data I need, but using a gridview doesn't really give me what I need.
For example...currently the gridview displays data like:
