I have a listview
Each row has a Radio button in the first column.
User will select multiple rows(Records) by checking the radio button and then click a submit button.
No postBack should happen untill the submit button is clicked.
How do I then get the RecordID from each of the selected row in code behind.
I'm using the code below to extract data from a gridview and populate it into textboxes for the days and two drop downs for Project and Category.
For some rows in the gridview everything but the category ddl populates correctly. If I click the row a second time the category ddl displays the correct category.
why I have to click twice for some rows? And how do I fix this?

I have a link button that I want to function as delete. I have to do it this way because I want confirmation before allowing deletes. In my debugger, I flagged this block of code and run it line by line. For some odd reason, it thinks my selected row. Maybe I'm overlooking something? Here's my code behind source:

GridViewDetails uses templatefields. In edittemplate I put a button called "ButtonUpdateAdjustAmount" with OnClick="Update_AdjustAmount" in the EditItemTemplate for the "Amt to be Adj" column. There is also a textbox. My user's should be able to edit the textbox, but I also want the ability to click the button and the textbox populated with the correct calculated value. The formula varies based on the "code" column which is a dropdownlist called "DropListCode".
I am fairly new to asp.net, vb, etc...so forgive my code writing. Eventually I need to also put the same functionality on the insertrow for my gridview. But first wanted to get the edit one working. I am using templatefields for all columns and the FooterTemplate to perform the Insert New Detail Line.
I can get the functionality to work for the first data row and only if I take out the If code.SelectedValue = ... line and leave 1 static formula. However that isn't going to work. If DropListCode.SelectedValue is DNR then AdjAmt should be ((q_ordered - q_received) * cost). If DropListCode. SelectedValue is OV then AdjAmt should be (RKNumber * cost). If DropListCode.SelectedValue is NB the AdjAmt should be ((q_received - q_ordered) * cost). If DropListCode.SelectedValue is DAM then AdjAmt should be (RKNumber * cost)

View 5 RepliesHow to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items)

Label1.Text = item.Text;

No use, no value coming in to label.

I have a master page (Site.master) with a navigation menu linked to a datasource (Master.sitemap). I have a nested master page that has another navigation menu. For any item clicked in this nested navigation menu, I want a particular menu item in the Site.master navigation menu to be selected.
Here's my Site.master menu:

In the nested master page, Products.master I have this:

The master navigation and products navigation menus work just fine by themselves. But when I've tried to set the selected item of the master menu in the Page_Load above, I can't seem to access it. What I've found in trying to do this is the NavigationMenu seems to be uninitialized. The menu Items list is empty. What am I missing here? Why are there no menuItems in the Master.NavigationMenu control?
I'm trying to make sure a user selects a date in the calendar by checking for it with OnItemInserting command...since I can't just use a validation control. what I need to adjust in this code behind to cancel the request and activate the label when no date is selected?

is there any way how to make some day selected by C# code?
View 2 RepliesSince setting item.selected to true will lose the mutual behavior and setting list.SelectedValue (readonly) doesn't get any button selected.
I am using list.SelectedIndex to assign the selected button. as follow :
//step 1. find the item by value
ListItem item = list.items.FindByValue(obj.ToString());
//step 2. find the item index
list.SelectedIndex = list.Items.IndexOf(item);
I make it into an extension method. But feel stupid about this procedure to simply just assign a selected value. does anyone have a better approach?

I just wrote something small up with a GridView databound to the products table of the northwind database to play around with the control. I added a template field and put a checkbox in it, ProductID, ProductName, and UnitCost. I can successfully loop through the GridView and find the rows that have the checkbox checked, and can get ProductName for each row, but keep erroring out on ProductID and UnitCost. It's probably something small, but I just cannot figure it out.Here is what I have so far:

This all works fine the first time, but as soon as I select a different ddlCampaign item, it throws the"A field or property with the name 'FieldName' was not found on the selected data source" ERRORI kinda understand that it has retained the column mappings from the previous datasource assignment/binding and because the new datasource has different column headings it is throwing the error. What I can't seem to achieve is a clear or reset of defined gridview columns before adding the new columns. I cannot clear all columns because part of the GV defn is declarative.e.g.
gvReport.Columns.Clear();
gvReport.AutoGenerateColumns = true;
I have also tried clearing the previously added columns before new assignment/binding but it gives the same error.e.g.
for (int i = 2; i < gvReport.Columns.Count; i++)
{
gvReport.Columns.RemoveAt(i);
}
