ASP.NET Find DropDown Value Inside Repeater Control?
May 31, 2009
I want to find the values from a number of dropdown controls inside a repeater control. I eventually want to build a multidimensional array, so I can loop through each item and add them to a database table.
how I can get this to work. I want to distinguish dropdown controls inside a repeater control. I understand now about the lifecyle and how the buffer is already writen, but what are my alternatives? Here is what happens
Code File
Dim repeatTimes((TotalAdInsured - 1)) As Integer myRepeater.DataSource = repeatTimes myRepeater.DataBind()
I have one control named thumbviewer inside repeater. I want to set its imageurl in code. Currently it's done in aspx itself as <asp:Repeater ID="Repeater1" runat="server" > <ItemTemplate> <span style="padding:2px 10px 2px 10px"> <bri:ThumbViewer Id="Th1" runat="server" ImageUrl='<%# Eval("Name", "images/{0}") %>' Height="100px" Width="100px"/> </span></ItemTemplate> </asp:Repeater> How can I set ImageUrl in code?
I'm using a repeater ListOfArticles and have controls inside it like ddlSizes and btnSelectArticle. Normally you can just double click the control and in the aspx.vb page you can specify an action. I have heard something about Findcontrol, but can't figure out or find much information that I understand. I don't want to sound like an ass, but I would really prefer help for the aspx.vb page and not in C# or Javascript.
An example of what I'm trying to do is, once you've clicked btnSelectArticle the label lblSelection receives the following values Amount: txtAmount - Size: ddlSizes.SelectedValue.
I have a simple gridview that contains a label in one of the rows. I'm trying to access that label in the RowDataBound event, but for some reason I keep getting a "Object reference not set to an instance of an object." error on the line where I am using FindControl.
I've tried using "gvQReport.FindControl", "e.Row.FindControl", and "Me.FindControl" but nothing works.
This post is similar to one I have posted before about a dropdown filtering results in a gridview. Well now I need this dropdown to attach itself to a repeater that will filter results into a gridview. I have tried rptLetters.DataBind() in the code behind of the dropdown list, but that doesn't seem to be changing any of the letters at the top of the page when I click on different items in the dropdown list.The screenshot doesn't show enough of the products, but in this case it skips from G to L, and in the repeater the letters between G and L are still shown. I need to be able to get that repeater to recognize the letters that start each of the products associated with the company chosen.
Ok so my issue is I have three repeaters. Within that repeater I have another repeater and a third one in the second. There is more in between but that's not relevant. Below the HTML is my VB code. My issue is that rptCrashPercentageAvg reutrns Nothing. How can rptCrashStatsDisplay access rptCrashPercentageAvg?
I have a repeater which displays products. Users can select a Size - dropdownlist and an Amount - textbox. Then they press Order or Cancel. When they press Cancel I would like the values of Size and Amount to return to their default values. Protected Sub lbtnCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbtnCancel.Click rpt.ProductList is the repeater name lblFeedback.Text = ("") lblFeedback.ForeColor = Drawing.Color.Black End Sub I am using VB.NET.
I have a label and dropdownlist inside a repeater. When I click a button outside the repeater I would like to access the label.Text value and ddl.SelectedIndex value.
I have this label inside a repeater <asp:Label id="lblsub" runat=server text="sdds" /> I am trying to change the text of this label,this is the code behind

unfortunately this code doesn't work for me ,the text value doesn't change,
So, when I click 'btnSaveAndCompleteLastStep' I want all the UpdatePanel in 'rptContactSteps' to update. Having the UpdatePanel inside the ItemTemplate should help prevent having to re-load the html/text that populates the Eval("script") & Eval("notes"), since the value of these variables could be very large and over a 3G connection this could be very costly (in time & money).
I though by adding the async trigger it'd work as I have used this type of trigger before, but not when inside the Repeater. Currently the UpdatePanels aren't getting updated at all, except from the one from which the button was pressed.
Why cant i accesss this textbox inside the repeater I have used the following on the rgroups itemdatabind no matter what i do it says the object cannot be referenced.
I have a simple questionnaire system which shows a random number of questions to the user out of a certain total in my database.I have 2 separate tables: Questions and Alternatives (which are the options to answer) related by QuestionID field in both tables. I rendered such questionnaire using Nested Repeaters (parentRepeater for questions and childRepeater for the options) and it shows correctly on the page.Each option is a radio button which I had to use it as a HTML instead of the Standard Server Control <asp:RadioButton> because of the Dynamic ID problem inside a repeater.[code]What I don't know is how do I get all the questions answered by the user given that I don't know the QuestionIDs and the Alternative IDs since it's randomly generated and using a HTML input tags?
However, I recently tried to use it in a repeater. Essentially my company wants to have a number of different values displayed as the main repeater (no problem setting that up). When the user clicks on a field within that repeater, they would like the collapsible panel to open up and display the detail information for that piece of data. The details are within a sub repeater.The repeater functionality and the child repeater functionality are working perfectly. So the repeater and the child repeater aren't the issue. If I take the collapsible panel extender out the data displays perfectly.The problem is that once I start opening and closing the panels, the screen rendering starts to go crazy, and there seems to be no rhyme or reason for it.
For example, on the initial screen rendering I get seven entries. They look perfect. Each of the seven line up across the screen and no extraneous data is shown.I click to open the first row, and it displays great. No problem. But when I then click it again to close the first row, I only see the first four rows of data, then a huge white space with a few seemingly random characters, then the next 2 rows, a smaller whitespace, then the seventh row. I click to open the first row again and everything looks exactly as it should again. Again close, again 4 rows, whitespace, 2 rows whitespace, last row.I reload the page and everything is ok.
So now I click on the second row to open it and everything looks perfect. I close the second row and I get the exact same result.Has anyone ever tried to use the ajax collapsible panel inside a repeater? If so, have you encountered strange rendering behavior such as this? And if so, were you able to get it to work?Here's a stripped down version of the
I am trying to add an attribute to a tag with ID 'SubNav2' on ItemDataBound which is in the HeaderTemplate of a repeater.ut I keep getting the error: Object reference not set to an instance of an object.Which i think is because it is not finding the object with ID 'SubNav2', am i going about it the correct way?
CODE BEHIND If e.Item.ItemType = ListItemType.Header Then Dim ulSubNav2 As HtmlGenericControl = CType(e.Item.FindControl("SubNav2"),
i am making a table through vb.net code (htmltablecell, htmltablerow..) no this table populates with an sql query and works perfectly. but inside this table in one tablecell, i need to add a dropdownlist which shall require a completely differernt query and shall run on its own on each row. so the code is as follows
Sql = "..." rd = ExecuteReader(SqlCnn, Sql) Dim newcounter As Integer = 0 While rd.Read()
[code]....
the ??? in the code is where the dropdownlist shall get populated each time with its own datareader and while loop and query.
I've got a datetimepicker control on a vb .net 2008 form. I have set it to show a custom format of "dd/MM/yyyy". The problem is this: - when i click on the arrow button, a small calendar is shown in which i should be able to select a date. The only way i can do that is by using the arrow keys and pressing Enter. Clicking on any date value inside this calendar doesn't do anything.How can i make the value of the datetimepicker change to what i have clicked inside the dropdown calendar?
I am making an invoicing application. I have a label (lblCost) inside of a UserControl (InvoiceEntry) inside of a FlowLayoutPanel (pnlEntries). InvoiceEntry represents a line item on the invoice, and pnlEntries is the "body" of the invoice. pnlEntries can hold several InvoiceEntry controls.
I am attempting to sum all of the lblCost values from each InvoiceEntry control to make a subtotal, and I want that subtotal to change automatically if costs are changed (e.g., a change in quantities being ordered). Is there a way to handle when the lblCost.Text property of any of the InvoiceEntry controls contained within pnlEntries changes?
