Forms Data Controls :: Datagrid Or Repeater Inside Of Datalist
Nov 3, 2010
I am trying to follow this tutorial(out of date) but the simplest I can find and understand to put a repeater or datagrid inside of a datalist.http://www.tutorialized.com/view/tutorial/DataGrid-inside-a-DataGrid/13926I get hung up in the cs part. Can I just add a sql datasource to the aspx page then call it from the cs like this somehow...my
Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.
I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.
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?
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.
I am going to have a page that list an (image, description, category) this needs to be an editable list (the user should be able to edit description or select a cateogry from a dropdown or delete the whole image). lets say I need to display 20 rows per page.here are my questions:1) should I use datagrid, gridview or datalist?2) would PagingBulletedList works well with any of the above control3) when I go to the database to get the rows , since i am going to have 20 items per page should I just bind the control with all the rows or should I just display the first 20 items and when the user click page 2 i go to the database to bring the second set of 20 items?
I have Datalist control in my application which contains one Gridview control as a child control in it. Now at the time of giving datasource to the child control, it gives object reference error.Note:I am binding the child grid at the time of ItemDataBound Event of Datalist controlMy code looks like :
I have a DataTable of datetime objects - starttime and endtimes for 1 to infinite (almost) weeks. I've created a webcontrol of my own because I can't get either a DataGrid, GridView or a Repeater to break line after each week in my DataTable.
But it most be possibly to make it happend.
My data is sorted by asc using my Startdate.
Is there an eventhandler on either of the mentioned controls where I can do my check for every 7th day and then make my control break into a new line for the next week and so on?
So the page is 500px width, and everything should centered.I get a DataList with RepeatColumns on 5, and set it to horizontal and also i add a datasource to it, with 4 items.
Everything is centered. But if i add 6 items to it, the 6th is below the first, so not centerd but aligned to de left. Logically like you add it to a table, but is there a possibility to center everything?"
I tryed it with a repeater and divs with float:left , but then everything is align to the left, i just want to center everything.
aspects of some controls in Code Behind (VB) with controls inside a datalist and/or repeater. I have read a lot of stuff on using some tricks but none seem to work so far. I am new to ASP.net so some of the explanations are too cryptic as well. Below is a section of code that I am trying to change. This example is attempting to make the label visible if the dataitem is true and hidden if false. No matter what I seem to do I cann't reference this label to change. I also want to change the text on some other controls in this dataitem if the returned value is a certain value.
I have this list of names where I want the location underneath each name but nothing is showing up. Is it not actually possible to bind the repeater's datasource to the items in the datalist because nothing is really selected in the datalist - it's just all there?
I have a DataList control setup with a Repeater inside it. It's displaying Ranks just fine, but the problem is I don't know how to make it start over with each DataList.
Right now, if there are two rows in the PointsCat table, it creates two DataLists (new DataList for each ID) and populates the Repeater with the person's rank, name and points from the Points table. The CatID in the Points table is a number equal to an ID in the PointsCat table (to tell which DataList's Repeater to display the data in). This code currently just orders ALL the entries from my database table, so the first Repeater in the first DataList may end with a ranking of 4 (4th), the first item in the next DataList's Repeater starts with a rank of 5...instead of starting over with 1.
So my current page may show something like this (notice the rank didn't start over in the second category):
Points Category 1 Points Category 2 1 John Doe 400 4 Janet Doe 275 2 John Smith 390 5 Johnny Smith 270 3 Jane Smith 380
My SqlDataAdapter line is below. I need it to start over the ranking for each CatID. Is it possible to do that within this line?
I have made a monthly view custom calendar.I have taken a repeater to make the control.Now what i want is there is a treeview showing some data.I drag from that treeview onto Datalist/Repeater control.on dropping the value should be inserted into database
