Forms Data Controls :: Getting An ID Number From The Gridview To Populate The Insertitemtemplate?
Jul 8, 2010
I am new to asp.net and am hoping this is an easy question. I have a gridview and then I have a couple of dataviews whose sqldatasources looks to the gridview' to be populated based on an ID number in the first column. If there are no rows returned to the dataviews, I generate an insertitemtemplate.
The problem is that I want to pass the value from the ID column in the Gridview over to the insertitemtemplate (because I don't trust the end user to get the ID right). The insertitemtemplate is now blank in all fields. ( I'm doing this in C#).

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.
How can I fill those DropDownLists?

The situation: a FormView with an EditItemTemplate and an Insert Item Template. When the page is entered and a record exists in the datasource, everything is fine with the Formview in Edit mode and the Edit ItemTemplate being used. But when no record is present, the FormView uses the EmptyDataTemplate even though it was switched it to Insert mode. Here is the code used to switch modes, fired in the OnDataBound event:
protected void SetModeAndHeadings(object sender, EventArgs e)
{
if (FormView1.DataItemCount == 0)
{
FormView1.ChangeMode(FormViewMode.Insert);
}
else
{
FormView1.ChangeMode(FormViewMode.Edit);
}
etc...
}
Is the problem that it switched to Insert mode too late? What has to be done differently here to automatically switch between Edit and Insert modes?

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?

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.

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 currently have a gridview that has 1 column with radiobuttons. I then have a update button to update all the selected records. But what i want to do is add a step before the update. I want to add a multi-line textbox for each radiobutton selected to allow them to add notes/comments for each record before the update occurs.
Because the textbox will be large to allow them to enter the comments, i wanted to list them out seperately per record selected. Maybe a gridview is not what i need for the 2nd part, but thats the scenario and looking for suggestions on what / how to do it.
Example:
GRIDVIEW1
ID column1 column2 column3 radiocolumn
1 1111 2222 3333 Yes / No (selected Yes)
2 2222 3333 4444 Yes / No
GRIDVIEW2
ID NotesColumn
1 Texbox displays here

I have a Detailsview grid with an SqlDatasource, this DVG is only going to be used to insert records. The primary purpose of the DS is to populate a DDL control in the insertItem Template that I created my code is this:
[Code]....
The DDL control populates correctly, but when I try to modify the INSERTCommand property in my DS, I try to assign the value to my parameters "TesterID" and "TesterDate" but the only options for controls to pick from, is the DGV but not the DDL in it. I assume it has to do with the InsertItem template but even if I reset it I still cannot pick the textbox as a control that would give the value to my parameters.
I did find a workaroun by build a public method and calling it in the onclick event of the insert button but looks like I have to create another connection to the database which to me seems unnecessary since I already have a DS and everything. how can I do this without having to use my method. here is my method just in case.

And code bihind: protected void GridView1_PreRender(object sender, EventArgs e) { DataSet ds = new DataSet(); ds.ReadXml(Server.MapPath("RestaurantData.xml")); GridView1.DataSource = ds; GridView1.DataBind(); } But say if I have multiple child of a node in the XML file, say, Dennys 730 W.

I am trying to populate a gridview when you select the dropdownlist.selected value. I don't want to use the sqldatasource or any other datasource. I am trying my best to achieve this, but didn't succeed till now. One of my friend said that i need to get the selected value from dropdownlist and search for the data in the database using the selectedvalue and populate the dataset and bind to the gridview.

I have 2 drop downlists 1 gets the User hits my sql database and pulls back all my users in the database. I have post back on. The second drop down brings back all the account numbers for the user that is selected in the first drop downlist I have that post back on also.
My gridview then uses those 2 dropdownlists to populate for that user and that account number selected.
Now for the problem.
User Albert is in the drop down when page is loaded because its sorts by name the first account number for albert is in the 2nd drop down and the gridview works on page load for albert and account number 1 i can select account number 2 and the gridview changes.
I then switch user to Bill and it populates the 2nd drop down with Bill's account numbers however my gridview at this point is still showing alberts account information. I have to take drop down 2 and select another account say account 2 then my gridview displays bill's account 2 information i can then switch back to account 1 for bill and see that account information.
What do I need to do so that my gridview will populate when the first dropdown is changed to match the 2 new values?
Here is my code

I have a page with a gridview in which I currently populate with a stored procedure. There is an additional column I want to add to the gridview and populate (either dynamically or with a sqldatasource). Though I'm not sure how? If I create it dynamically, I don't know which gridview event to use (I would guess the rowcreated event)? Which is better or is there a better alternative to what I've proposed?

I have a textbox1, button1 and a GridView1.
I have configured a datasource for gridview1 to execute a Stored Procedure on a SQL Server Database passing a parameter with the value from textbox1.
My question is, how do I code the button1 Click Event to populate the GridView1?
GridView1 already has the datasource configured, I just need to trigger it via the button1 Click Event.
