Web Forms :: Retrieving Item Values From A Dynamically Populated CheckListBox During Page_Init

Jan 15, 2010

i have a checklistbox that is databound during Page_Init in an

If (!Page.IsPostBack)

block. the user can then check off certain values, and click an asp.net button which posts back the form and renders a crystal report on the same page.

i need to be able to determine which items were checked in the control so that they can be used as parameters in the crystal report. rendering must be done during Page_Init.

the checklistbox object is on the page during design time; only the items are dynamic.

i tried using the Request.Form object during Page_Init to obtain the checkboxlist's items but either i didn't code it correctly or it can't be done that way...

can the checkboxlist items' values be obtained during Page_Init, and if so, how?

Forms Data Controls :: Populating A Grid View With Data From SQL Datasource?

Dec 22, 2010

I'm populating a grid view with data from an SQL datasource. The database has a a list of performing artists and lots of details. The gridview initially, shows the ArtisID (Primary key) , and artist name and music style. So far this is all simple and easy. This is done.

Now I want to be able to click on the ArtistId (Select Column) and move the customer to another page where I show indepth details about the artist. How do I do this???

In Vb.net I had a 'Celldoubleclick' event, and I redirect the client. But how do I accomplish the same in asp.net? I already have the primary key value

primekey = datagridview.selecteddatakey.value

Forms Data Controls :: Dynamically Populating Fields In A Gridview Depending On Data In A Table?

Jul 17, 2010

I have a gridview that is populating from a SQL DB and working fine. However, based upon certain data I find in fields in the SQL table, I want to place a 'n' or a 'y' in extra columns in the gridview that I am assuming need to be templatefields. My thought was I could maybe add 8 template columns and then I could put a 'y' in the appropriate column based upon the data I find the table. For the life of me, I cannot figure out how to do this. I want to do this at rowdatabound time ( i think) but I just cannot find out how to, in my code, put that 'y' in the columns. Is this the right way to do this or do I need to do it another way? How do I get that 'y' in the proper column?

Forms Data Controls :: Populating A DropDownList In A ListView InsertItemTemplate

Jan 19, 2010

I have the following ListView (extra code removed for clarity) :

<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<EditItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>

The Insert row in the ListView has an empty DropDownList and GetCountries() is not called. However, if I click the Edit button on an existing row, GetCountries() is called twice (not sure why) and the DropDownList is properly populated. Why isn't the InsertItemTemplate DropDownList getting populated?

Forms Data Controls :: Populating Formview Fields Using Database?

Feb 1, 2010

I'm not sure if I can explain this properly, I just need some advise. I'm working with a formview and datasets to populate the information. However I have a table specifiying which fields to display. In my table If cell, work and home fields are selected then those fields must be populated in the formview if they not selected then it shouldn't be shown. These are 2 different datasets being pulled into the formview.

Right now I have a datasource populating the formview via the wizard, not sure what to do next.

Forms Data Controls :: Populating DropDownList In FormView From Code Behind?

Oct 25, 2010

On my formview I have a drop down list that is populated with the names of the files in a certain directory. This works fine, but when the drop down list selected value is bound to the database field I get the following error :

'ImageFileDropDownList' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value

I have setup other drop down lists in the same formview populated from SqlDataSources and these all work fine. I can see perhaps why this is an issue because I have not specified a DataValueField or a DataTextField for this drop down that is populated in code (whereas I can for the SQL bound ones) because I'm not sure what these settings would be.

I need to have a "blank" option as well so that the field does not default to the first value in the list.

My code (I have stripped out some meaningless controls) :

My code behind populating the ddl :
