DataSource Controls :: Populate Label / Textbox From Dropdownlist In Insert Item Template
Nov 19, 2010
I've been trying to find a solution to my problem for about 2 days now, and have found nothing. I am new to .net and not really sure how to accomplish this. I have 4 tables in a database, Vendors, RepairCos, Cons, ConRepairHistory. What I'm trying to do is make a page called SendOutForRepair.aspx that has a insert item template where the first control is a dropdownlist that is attached to the Cons table (got this figured out) and is populated with the Serial Number field. I would like the selection from the dropdownlist to populate the 2nd control (VendorID) that is also from the Cons table....

I am trying to bind dropdownlist in Gridview under EditItemTemplate under RowBound event. But it gives me blank rows in the drop down list.Here is my Design
<asp:TemplateField HeaderText="Description">
<ItemTemplate>
<asp:Label ID="lblDescription" runat="server" Text='<%# Bind("Description") %>' Width="400px"></asp:Label></ItemTemplate>

I see the dropdown but the dropdown is blank, but there are rows in the database for this column and in the footer row it is working fine.

I am trying to Populate a label or a textbox a Primary Key Value from a Data base. My goal is to enter this value into serveral other tables in the same DB. The DB is called Record_Review.mdf and it is local to this machine through asp.net. The table im pulling from is tblDemographics and the column I want to use is CaseID. The bit of code i got so far is:

lblCaseID.Text = ds.tables[0].rows[
"CaseID"].toString();,

I would like the selection from the dropdownlist to populate the 2nd control (VendorID) that is also from the Cons table.
example record from Cons Table: Serial number VendorID
508585 1
so when 508585 is selected in the dropdownlist, it would populate VendorID with 1 (this is my issue)once this happens, the user would fill in the other fields (hours, issue, repairco (also a dropdownlist linked to RepairCos table), RA Number, DCI, DPU, DRB, Cost, Record (which is a identity field and primary key for table) and when the insert link is pressed will insert all 11 fields as a new row in the ConsRepairHistory table. so the new record in the ConsRepairHistory table would look like:
Serial Number VendorID Hours Issue RepairCoID RA Number DCI DPU DRB Cost Record
508585 1 2250 alarming 2 20222 11/16/2010 11/17/2010 null null 3
the RA Number, DCI, DPU, DRB, Cost all allow null values.

I am working on a project where the customer has a large database of products, they want to select the product by the id number and I thought it best that the description also show up. What I have is a dropdownlist that is linked to the id number in the database table and that works just fine. My problem comes when populating the corresponding description from the table into either a textbox or label(doesn't matter which one I use) I can accomplish this without ajax just fine but we would like to reduce the postbacks to the server. I have never used ajax before Here is my code from the aspx file.

Here is the code in the cs file

I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.

I am using Asp.net with C#.
I have one gridivew, which is showing 20 records. And also, in item template of Gridview, I used one dropdownlist. It means there are 20 dropdownlist with all the 20 rows. That dropdownlist is already binded, means showing the records/items - 8 items. No issue with this.
Now, what I want is, when ever, I select any item from the drodownlist against each row in that gridview and click on the button "Save", it will save the id of all row with all the values of dropdownlist.

I have been trying for a while to populate a formview when I select an item from the dropdownlist. The dropdownlist is outside of the formview. For some reason, when I select a different item it does not change in the formview. Only the first item of the list shows up. I don't know where I'm doing wrong. I tried many things and suggested informatioin and I still could not get it to work. When I do try to switch I get this error message:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

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?

I have a Gridview which I'm populating through code behind. A couple of columns of the gridview I've set up to be drop down lists. What I want, is that when I run my Insert query, it takes the drop down list selected value, finds the appropriate ID and uses that ID as part of the insert query.
Below is my select and insert query.

I'm going to try to explain this the best I can. I have a datalist that is displaying a large amount of data based off a CollectionID number. Within each set of data are CollectorID numbers. Now there can be several different CollectorID numbers tied to each CollectionID number. So therefore, the same data is being duplicated several times with the different CollectorID number. What I would like to do is concatenate all the CollectionID numbers into a string that are related to the CollectionID number and populate that into the corresponding label.
I've tried modifying the stored procedure to concatenate the CollectorID rows from the table they are located in but that seemed like a very large challenge.
My latest attempt involved removing the CollectorID from the original query. Then I wrote a datareader on the ItemDataBound event grabbing the CollectorIDs but it is missing the first CollectorID in each set.

I am trying to change the textboxes in the FormView insert template to dropdownlists but they keep setting the parameters to null. Here's what I have:
[Code]....
In Page_Load
CType(frmSurvey.FindControl("ddlYearOfQualification"), DropDownList).Items.Add(New ListItem("2010", "2010"))
CType(frmSurvey.FindControl("ddlYearOfQualification"), DropDownList).Items.Add(New ListItem("2009", "2009"))
and in the SqlDataSource
InsertCommand="INSERT INTO [tblSurvey] (... [YearOfQualification] ...) VALUES ( ... @YearOfQualification ... )
And in insert parameters:
<asp:Parameter Name="YearOfQualification" Type="Int16" />
And the insert fails with YearOfQualification as null. If I sue the standard textbox:
<asp:TextBox ID="YearOfQualificationTextBox" runat="server"
Text='<%# Bind("YearOfQualification") %>' />

But after filling all the textboxes when i clicked on submit button it loops thru the items and there i need to read the textbox value of that particular item in a variable but unfortunately the value is blank even the data is there.
