Forms Data Controls :: Database ID For A Row Within A Repeater?
Dec 31, 2010
I'm using a repeater and need to change an image value based on the ID and folder value (both stored in a database); but to do this, I need to know that current database ID for that row.Is there a way to get the current database ID based on the row being rendered using _ItemDataBound???
Just dipping my toe with doing simple VB.NET stuff. Have used classic ASP, so im used to being able to place any field from a recordset whereever i want to putit , and i have just tried to recreate this event.Its got me a bit lost.. now i have read up and understand why it doesnt work - cant use DataItem in a HeaderTemplate - i get that, but how would you do something where you have complete control of the way the table is being set up? and you can use the contents of the container whereever you want, however you want?I just want to be able to get the values from database table, and put them into an html table, in a specific way.
I need a sample how I can check checkboxes in repeater using SQL statement. The checkboxes within repeater are populated fine and are named with ObjectName value from database but I just need to checked those values that are returned by a select statement:
private void CheckUserLocations() { // user reference that is currently viewed [code]....
I am trying to find a good way of building out dynamic controls in a repeater from sql. Basically I have bunch of questions(male/female, where are you from) and question type(textbox, radio button) in sql. In the repeater I need to build the control object based on sql table and the answer. Does anyone have a good example or ideas who it can be done.
I need to utilize about 30 different database values from within a repeater ItemDataBound Event and I am wondering if there is a better way to do it. I am currently exposing them by doing something like this 30 times:
[Code]....
Rather than making 30 declarations, is there a way I can make them all available as short variable names? The variable name could be the same as the field name.
My plain texts are image links and pdf URLs from a database table, in groups, in the correct order but I'm not sure how to render them correctly (sample image below shows what I am trying to render)
Is there any way to make a repeater template intelligent enough to render an "image link" OR "pdf link" based off the [type] column returned in the record?
table: pk Name Type (image or pdf) URL Description URL_Thumbnail (if image) GroupId (associate these records to each other) OrderNumber (order of these records within their GroupId)
I have a databound repeater and in this repeater is an imageButton. How do I pass info from the database into the click event? For example, I've got the description, heading and price fields populating labels, but want the id to go into the imagebuttons click event in order to build a querystring.
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...
I have two repeaters where i'am moving rows from one to another by jquery drag and drop.
My question is, I want to achieve the first and second columns (they are the parameters) of each repeater (table) so that could call a webservice to make the update on database. So, how I achieve this and how can i call a webservice passing to the method the parameters for each change on both tables.
I am displaying data in html table using Repeater. And I have two button for each row. When I click 1st button I want to insert particular row and using second button the same row to be updated. But my prob is When i click button all row is inserting. And I am using Button click event for two button.
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'm so confused I wasn't even sure what to make the title so that it would make sense.
Here is what I have:
[code]...
I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.
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.
