Apr 10, 2010
I have bind the Repeater control . After filling the Repeater control . I am dynamically binding the Dropdownlist. Now , if i have 3 rows in repeater the last two rows are binded in dropdownlist but i am unable to bind the first record's dropdownlist. Here's my code for dropdownlist binding
I am not clear when do I want to use a webservice over a sqlDataAdapter for dataRetrieval. I want to populate a repeater control which I have been doing from a dataTable that I fill from a sqlDataAdapter. Is there criteria when I would want to use a webservice to fill my dataTable?
I am having a 2 dropdown list, in the first dropdown I have 3company names,for each company I am having separate tables,every table have a empcode, if the user select the company name in the 1st dropdownlist, as per company selected the 2nd dropdownlist it will fill the list of employee codes as per the selection..
Here is what am trying to accomplish...I want to have a DropDownList that is populated by a field from a table. Then once a user selects one of the enteries, he/she then enters a value for that selection in a textbox, then clicks enter or add....now upon doing this, I want to have a GridView that tabulates all the entries the user adds, and keep a total of all entries as the bottomline in the GridView. I can't seem to wrap my head around how to get it done.Does anyone know how I can get this done, or are there examples out there that my searches have missed cause I haven't really seen any examples I could look at. I would think this should be a common solution that is used all over
I have a gridview which gets its data from a database tablenow i ghave added a dropdownlist to this gridview but this dropdown should get the data from another table and should set its value automatically with a foreign key from the gridviewi have added the code like below in my rowDatabound but it just loads 1 field and then how should i get the selectedValue according to the gridview id field??
Protected Sub Friends_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) If e.Row.RowType = DataControlRowType.DataRow Then Dim conn As New SqlConnection(HttpRuntime.Cache("con"))
I get data using sqldatasource control (about 100 reacords) and fill first dropdownlist with this data , I want to fill the second one with all othe data without one which selected in the first one ( I want to remove selected record from datalist and fill others in next dropdownlist) . and repeat this operation for all 25 dropdownlist. (i want in final 25 value without dublicate )
I am new to ASP.NET, trying to learn it. I am using ASP.NET 3.5 with VB for scripting. Also read some books. I just can't figure out how to bind a DropDown List inside a Repeater Control. I saw a few examples but none were clear enough and explained all the details. I want to populate the Drop-Down using values from a Database inside the repeater.
I also read this article [URL] but still can't understand how to bind dropdown in a repeater.
I want to display 2 things inside the Repeater Control.
1. User Selected Values (which comes in the form of an Arraylist) from a previous page using "PostBackUrl" method.
2. Then allow users to select values from a Dropdown list corresponding to each design code they selected on previous page. (the dropdown values here must come from a backend db)
Also, I want to control the number or rows displayed inside the repeater control. It should be equal to the number of "design codes" selected by the user on a previous page.
Asp.net 3.5 using code behind I am using a repeater control. My datasource appears in code behind. I decided to NOT have my listitems populate from the database. I want the user to select a value, send it to the database via an update statement, and then when the user returns to the page (on pageload), have the user's previous selections appear on the screen. note the following:
When I use textboxes and labels, ALL of my data appears within the table of the repeater control. However, when I replaced one of the text boxes (originally used for testing purposes only) with a dropdownlist, I get the following error message'ddlDDuring' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value My Repeater1_ItemCommandI updates the data within the repeater perfectly. On page load, I want the data from the database to display as the dropdownlist's selected value (or selected item.text). Here is my Asp code
I tried the following code changes on asp page: I changed "SelectedValue" to "Text" and still get the same error message I changed "SelectedValue" to "SelectedItem" and don't get the error message, but dropdown is not populated I set AppendDataBoundItems = true Set first list item value = "" Verified that every field in the table column matched the items in the dropdown list. There were NO null fields in the database.
I just want to understand this error message, as I have exhausted all that I am doing. I also made an attempt to bind the dropdown list, but sine this can only be done within the loop of finding the repeater control, I would either get an error message, or it just would not work.
I'm trying to bind a value to a dropdownlist. Here how the code looks like in the aspx page...Bind the textboxes below is not a problem...but its not working with the dropdownlist..
So basically, what i want is the value selected from the dropdownlist to be remembered after i press next button and back button..
I have a dropdownlist in a repeater and it's firing the SelectedIndexChanged event but in teh event handler I can not get the dataitem associated with the row that the DDL is in. Here is the code:
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?
i need to Filter and display Google Map Markers from database based on DropDownList selection. for that I need to pass the selected value of DropDownList to the query.What should i do in the following code to do the above task?
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI;
I have two dropdownlists inside a repeater. And based on the value I pick in the first dropdownlist the second needs to get populated (both need to be populated from the DB via stored proc). I am adding the code I have so far but it's not complete
I have repeater control on page which bind with sql data source.i have dropdown to filter the records of repeater on button click event it refresh complete page i just want to show a wait message to user and just refresh repeater data instead of complete page refresh.i do not want to use ajax update panel.
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.
