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?
I have a dropdown list in ListView control in InsertItem Template. I want to bind the DropDownList when I Click on Link. I want to bind it in CodeBehind not to use Datasource. I tryed lot but not finding the DropDownList. See My Code....
<InsertItemTemplate> <tr> <td colspan="7"> </td> </tr> <tr> <td colspan="7"> <table border="0"> <tr> <td> </td> <td> Sector</td> <td>:</td> <td align="left"> <asp:DropDownList ID="DropDnSector" runat="server" ></asp:DropDownList> <asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server" Display="Dynamic" ControlToValidate="DropDnSector" SetFocusOnError="true" ValidationGroup="vgUpdate">* </asp:RequiredFieldValidator> </td> </tr> </table> </td> </tr> </InsertItemTemplate> lnkNew is my linkbutton outside the ListView Code Behind: Protected Sub lnkNew_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lnkNew.Click Try lvSubscription.InsertItemPosition = InsertItemPosition.LastItem lvSubscription.EditIndex = -1 BindDropDownList() fn_ShowSubscriptionLevel(fn_BindSubscriptionLevelEvents) Catch ex As Exception fn_ShowMessage(ex) End Try End Sub ------------------------------------------------------------------------------------------------------------------ Protected Sub BindDropDownList() Try Dim objSector As IEnumerable(Of SystemBuilder.SystemBuilder_Sector) Dim objSubscriptionLevel As SystemBuilder.SystemBuilder_SubscriptionLevel Dim DDLSectorctrl As DropDownList objSector = CSectorDB.CSectorInstance().GetAllSector() If (lvSubscription.InsertItemPosition = InsertItemPosition.FirstItem Or lvSubscription.InsertItemPosition = InsertItemPosition.LastItem) Then DDLSectorctrl = CType(lvSubscription.InsertItem.FindControl("DropDnSector"), DropDownList) If DDLSectorctrl IsNot Nothing Then DDLSectorctrl.Items.Add(New ListItem("--Select--", "0")) For Each ObjRec As SystemBuilder.SystemBuilder_Sector In objSector DDLSectorctrl.Items.Add(New ListItem(ObjRec.SectorText.ToString(), ObjRec.SectorID.ToString())) Next End If ElseIf (lvSubscription.EditIndex >= 0) Then Dim DDLSectorctrl1 As DropDownList DDLSectorctrl1 = DirectCast(lvSubscription.Items(lvSubscription.EditIndex).FindControl("DropDnSector"), DropDownList) If DDLSectorctrl1 IsNot Nothing Then DDLSectorctrl1.Items.Add(New ListItem("--Select--", "0")) For Each ObjRec As SystemBuilder.SystemBuilder_Sector In objSector DDLSectorctrl1.Items.Add(New ListItem(ObjRec.SectorText.ToString(), ObjRec.SectorID.ToString())) Next objSubscriptionLevel = CSubscriptionLevelsDB.CSubLvlInstance().GetSubscriptionLevelDetailsBySubscrptionID(ViewState("ID")) If objSubscriptionLevel IsNot Nothing Then DDLSectorctrl1.SelectedValue = objSubscriptionLevel.SubscriptionID.ToString() End If End If End If Catch ex As Exception End Try End Sub
I try to datbind a listview which is inside another listview InsertItemTemplate.
[Code]....
I'm binding the listivew in the parent listview onitemcreated events. I receive the error Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I am using a Listview with InsertItemTemplate bound to a LinqDataSource with a child table in the ORM datacontext. This table has a relationship with a parent table in the OR/M datacontext. The record is to be inserted in the child Table. The parent table is bound to dropDownList in the InsertItemTemplate to provide a user friendly name. Using the ListView ItemInserted event in debug, I can follow the execution and no errors occur BUT no record is inserted. I confirm this by a showing all Table Data in the SQL Mgmnt Studio. The child to parent table seems to be causing the problem because when I delete the relationship in the OR/M .dbml , I am ABLE to insert records. I am using Scott Mitchells' Using ASP.net 3.5 ListView with Data Pager controls: Inserting Data as a model. I can provide code if required, but what is going on with the deleting of the relationship between child and Parent.
want to find textbox inside InsertItemTemplate in listview there are two list view want to find textbox in the second listview that is inside listview i used that code but told me that there is error.
Dim lv As ListView = DirectCast(Me.FindControl("lv"), ListView)Dim lv2 As ListView = DirectCast(lv.Items(lv.SelectedIndex).FindControl("lv2"), ListView)Dim txt As TextBox = CType(lv2.Items(lv2.SelectedIndex).FindControl("txtCode"), TextBox)' If txt Is Nothing Then txt.Text = dr.AssetCode
I've googled around for a couple of days now and tried different solutions posted here and there, but nothing has worked so far. Therefore I'm forced to write a new thread about this subject.
I'm working on a solution containing nested listviews. The top listview lists different projects, and in each project a nested listview lists images from that specific project using a nested sqldatasource. Inside the nested listview I want the user to be able to add new images, and i'm using the InsertItemTemplate of the nested listview. When inserting a new image, the project need to be specified, as the project is a foreign key in my image database. The problem is that in my InsertItemTemplate, "Bind" and "Eval" does not work (I believe this is by design). Therefore, when adding the new image I don't have access to the project. I'm using the ItemInserting event of the nested listview to upload the image, and the optimal solution would be to have access to the project in this event and just pass it on as a parameter.
I thought this one would be easy, but no go. What I am trying to do is the following: I have two DropDownLists in my InsertItemTemplate, each bound to its own datasource. After the fields in this form have been filled out and the ItemInserting event fires, I rebind the ListView to its datasource, but the DropDownLists turn out empty. I tried to bind them in the ItemInserting event and it seems they get filled, but nothing shows up in them when the page loads. I also tried to fill them in the ItemDataBound event, but the e.Item.ItemType == InsertItem doesn't do it.
I have a ObjectDataSource and a ListView referencing it.
I have created a Templated User Control (see: http://msdn.microsoft.com/en-us/library/36574bf6.aspx) and placed it in the ListView's InsertItemTemplate It has one template <ContentTemplate>. Inside that template, I've defined a couple of server controls with their properties = '<%# Bind("colName") #>'.
I have connected listview by using datasourceid that means by usingĀ "sqldatasource1" now i want to change value of listview at run time according to search so for that i am using datasource at codebehind. but it give an errorĀ
"listview have already bind with datasourceid you can not bind it with datasource"
I have a listview that is bound to a table. I want to select a record from the listview and that record display in the detailvew from which I can edit. How do you bind these two controls so the detailview uses the records selected in the listview?
I am using a listview to which I want to bind the MembershipUserCollection which you get from GetAllUsers(). I don't want to use reflection, I want to assign it in the ItemDataBound event of my listview. I've done this before, but with datatables. The code will be something like DataRow dr = (e.item.DataItem as DataRowView).Row. You can then access specific columns with
dr["ColumnNamehere"].ToString().
But how do you do this with MembershipUserCollection?
I have a ListView where I am trying to implement Updating. My update parameters are not sent to update command correctly. The value sent is the original value and ignores what I type into the EditItemTemplate. Running a trace on my SQL Server verifies this. In this example, I am only trying to modify [dedamt]. What is wrong?
i would like to sort a listview. i don't have a datasourceID. i bind the datasource manually. i think of using jquery(tablesorter) but i don't know how to use it.
I successfully bind ListView DataSourceID to ObjectDataSource but it binds only initially on Page_Load event. When I want to bind another data through a Button_Click event, the new data doesn't bind.
aspx code:
[Code]....
Codebehind:
[Code]....
On Page_Load, I get result:
A1 <hr /> T1 A2 <hr /> T2 A3 <hr /> T3
When I Button1_Click, nothing happens, no error, no any more results and _airLineData is 53 records, not 3 records (A1T1 to A3T3) I want the binding to be with DataSourceID to ObjectDataSource (not through DataSource property and control.DataBind() method)
i am facing a minor problem but can't find out its syntaxi have listview, and inside the template i have 2 labels, in design time i bind 1 label to one column thatis 'type' and depending upon this type i want to bind other labels to different columnsif type is question than 2 label will have to show data of question columnif type is job than 2 label will have to show data of job, so on........how to accomplish this,in databinding event handler i can check the value of typebut i want to know the syntax of binding 2 label in run time, with different fields using EVAL
