Data Controls :: Error When Binding DropDownList From Database

Dec 23, 2013

I am using a dropdown list in gridview and populating it from database.However ,i am getting "object reference not set to an instance ..." error even though i have reference.I have two more similar drop down list and they are working perfectly.

I am uploading the options for the dropdownlist from a "tab delimited" text file for all the dropdown list.I am not getting where exactly the problem is.

<asp:TemplateField HeaderText="Property" HeaderStyle-Wrap="false">
<ItemTemplate>
<asp:Label ID="lblProperty" runat="server" Text='<%#Eval("Property")%>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:Label ID="lblProperty" runat="server" Visible="false" Text='<%#Eval("Property") %>'></asp:Label>
<asp:DropDownList ID="ddlPropertyEdit" runat="server"></asp:DropDownList>

[code]...

Data Controls :: Saving DropDownList Value To Database - Error Converting Data Type Nvarchar To Int

May 7, 2015

I am using  a  viewstate to store the company Ids and splitting at hyphen.

protected void onCompanychange(object sender, EventArgs e) {
ViewState["companyID"] += companydropdown.SelectedValue + "-";
String companyids = ViewState["companyID"].ToString();
string pattern = "-";
company_array = Regex.Split(companyids, pattern);
company_length = company_array.Length;
}

Company array is a string array  where i have stored the company ids

the problem is company_array[0] has the initial value of the dropdownlist(company) --select company which is why m getting the error(cannot convert data type nvarchar to int) .  I have used the same logic in many places in my project it did not give any error.

int count = 0;
company_length = company_length - 1;
while (count < GridView3.Rows.Count && compid_counter < company_length ) {
cmd = new SqlCommand("insertWorkDetais", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@trainerId",trainerID);

Forms Data Controls :: Binding Dropdownlist To Gridview?

May 26, 2010

I have two tables. t1 and t2

t1 is related to t2 through Order Numbers

these order numbers in table t2 have many part numbers(and hence the need for a second table t2)

I can display t1 using gridview just fine

In that same gridview iI have added a template column containing a dropdownlist(to show partnumbers)

now how can I bind this dropdownlist to the order number so that when the page is loaded the user can click on the dropdownlist to see all the partnumbers associated with that order number.

C# - Creating A DropDownList From Database Entries And Then Binding It In Form Submission?

Jul 4, 2010

I have entries for an enumeration stored inside a database table with only the following fields: ID and Name. I want to show the values stored inside this table inside a DropDownList on a form. The user then chooses a value and submits the form.

I found a way to easily create a DropDownList from an enumeration (although it would probably be best to just populate the DropDownList with the Name fields of all the records in the table). However, I haven't found a way to later bind the DropDownList in the form submission to an integer value to put into the database (FK - PK) with the other form values.

is it possible to fetch DropDownList content via AJAX and have it be put into the DropDownList and into the SelectList in the ViewModel (with both the ID and Name parameters)? I want to selectively fetch content based on an input the user makes and I want the ViewModel to then be filled with that fetched data.

Forms Data Controls :: DropDownList Binding And String Array

Jul 14, 2010

I have a gridview where I can browse an user's information. Through the gridview I'm also able to edit some of this information. A recent change in my client's needs demands that one of these fields is now a DropDownList. This field represents a user's "schedule" (not literally a schedule but works like one), and the different schedule options to be assigned to a user are shown in the drop down list.

Problem: In the drop down list I want to show list items like "9-12 15-17", "10-14 15-18" so that it is easy for the administrator to tell which schedule he's assigning to an user. However, that shouldn't be their actual value. I need "9-12 15-17" to actually be '1' since this is the schedule ID that I'm trying to pass on to the DB.

Here's what I have so far:
[Code]....

And with this last method I change the selected item's value to the Index. Meaning that if I select "9-12 15-17" which has an Index of 1 in the dropDownList, the actual value is now 1. Again, this is the behavior I expect. My experience with ASP is quite little as I'm new on this, but as far as I know, this only actually updates the string array. How would I go about modifying this to reflect my updates on the database? All input is taken into account.

Forms Data Controls :: Binding A Textbox To A Dropdownlist Selectedindex?

Feb 11, 2010

I'm having trouble binding my textbox to my dropdownlist. I got it to work but I don't think it is the correct way of doing it. I have my DDL bound to a datasource and populating everything correctly. However, I couldn't find a better way of binding my textbox to it besides using the FormView control and its counterpart, Templates (edit,insert,etc) It looks messy and i was hoping there was a better way of doing it. I've researched it online for awhile now but I couldn't understand how to implement for my situation.

My DDL has company names in it and the datasource has all the information from the table including what I'm trying to have my textbox pull (Address).

Forms Data Controls :: DropDownList Binding - Ways To Increase Speed?

Oct 20, 2010

I have a gridview that displays query results on a reporting page for a "home-grown" CRM application. From the gridview, a link can be clicked which opens a modal window that contains an iframe linked to a "details" page where record specific info can be viewed/altered. On the details page there are 10 or so dropdownlists (ddls) that are bound every time the page is called. The ddls are bound using a method similar to the example below. I am looking for a way top speed things up a bit. The details page could be called 10-20 times in one session and every time the page loads these ddls have to be bound from the same methods but for different records. What are some options for speeding up the load time for this page??

Forms Data Controls :: Binding Data To Dropdownlist In Web Developer VB?

Nov 17, 2010

On page load, dropdownlist1 needs to be populated with a list of string objects in a specific table in a sql database. Everytime the selected item in the dropdownlist1 changes, dropdownlist2 needs to be populated with a different table from a database ( I don't know if it can be the same database or not). And it needs to be dynamic, so that everytime the value in dropdownlist1 is changed, the items in dropdownlist2 need to change. All this si being done in VB on a Web Form.

How would I go about doing this? What would the code look like?
