ListView CheckBox issue - c#

I'm having a ListView in grid format which comprises headers as (NAME,ID,ADDRESS,GENDER,MOBILENO,PHOTO,BLOCK).
The BLOCK column consists a CheckBox in each row.
When the checkbox is checked in the BLOCK column,
that particular row of the checkbox should be changed to ReadOnly,
resulting in change of that particular row's backcolor.
my listview coding in aspx is...

.NET Delete in ListView isn't passing any values

For some reason, all my ListView functions work, except my delete button. I have debugged, and it points to the right method for deletion, but it's just passing all null values. I have no idea what the issue is, everything else seems to be working just fine. here is my listview code:

using (Pathway_Model context = new Pathway_Model())

EntranceRequirement existing = context.EntranceRequirements.Find(item.CourseID, item.ProgramID);
context.EntranceRequirements.Remove(existing);
context.SaveChanges();

TextBox in the RadGrid control doesn't make partial postback and fills the other controls

I have a TextBox (named as txt_lect_in) in RadGrid and I handled the TextBox changed event so it fills other textboxes (gv_txt_name,gv_txt_mobile,gv_txt_address,gv_txt_email) in the same grid.
The problem is:
The TextBox (txt_lect_in) doesn't fills the other textboxes, I know the reason but I don't know how to fix it.
After I remove the RadAjaxManager, it fills the other textboxes in the grid but it does full post back, how to keep the ajax manager and fill the controls at the same time?

ASP.net listview dropdown item getting the value from another table

I am trying to build an admin page in order to let the user create edit update the records of the specific table. "District" table has the following properties: DistrictID, DistrictName, Description, DistrictImage, CityFK. Since CityFK is just numbers which represents CityID of the table "City" and does not mean anything to the user I have used a dropdown menu instead and it displays all city names as "DataTextField" and CityIDs as "DataValueField" from the table "City". But my aim is to insert that "DataValueField" into the District table as CityFK. But whenever I enter a new District record and choose a City from the dropdown and press "Insert" button of the listview, CityFK of that regarding record is "0".
I paste the whole listview but if you look at the dropdownlist at the InsertItemTemplate or EditItemTemplate you will what I mean;

So I am trying to bind that dropdownlist values to the CityFK during Insert and Edit operations.

I figured it out. As workaround I added one textbox at the same column with the dropdownlist and set its visible attribute to false;
<asp:TextBox ID="CityFKTextBoxInsert" runat="server" Visible="false" Text='<%# Bind("CityFK") %>' />
In case you also encounter such a problem I add the code-behind and asp side here;
<InsertItemTemplate>
<tr style="">
<td>
<asp:Button ID="InsertButton" runat="server" CommandName="Insert" Text="Insert" />
<asp:Button ID="CancelButton" runat="server" CommandName="Cancel" Text="Clear" />
</td>
<td>
<asp:TextBox ID="DistrictIDTextBox" runat="server" Text='<%# Bind("DistrictID") %>' />
</td>
<td>
<asp:TextBox ID="DistrictNameTextBox" runat="server" Text='<%# Bind("DistrictName") %>' />
</td>
<td>
<asp:TextBox ID="DescriptionTextBox" runat="server" Text='<%# Bind("Description") %>' />
</td>
<td>
<asp:FileUpload ID="FileUploadDistrictInsert" runat="server" />
</td>
<td>
<asp:TextBox ID="CityFKTextBoxInsert" runat="server" Visible="false" Text='<%# Bind("CityFK") %>' />
<asp:DropDownList ID="CityFKDropDownListInsert" runat="server" AutoPostBack="true" DataSourceID="ddlCityFK_DataSource2" ViewStateMode="Enabled"
DataTextField="CityName" DataValueField="CityID" OnSelectedIndexChanged="CityFKDropDownListInsert_SelectedIndexChanged"
AppendDataBoundItems="true">
<asp:ListItem Text="-Stadt Wählen-" Value="0" ></asp:ListItem>
</asp:DropDownList>
<asp:EntityDataSource ID="ddlCityFK_DataSource2" runat="server"
ConnectionString="name=MedicalEntities" DefaultContainerName="MedicalEntities"
EntitySetName="Cities" >
</asp:EntityDataSource>
</td>
</tr>
</InsertItemTemplate>
Then I have added a "OnSelectedIndexChanged" event to the dropdown and assign the selected value to that textbox;
protected void CityFKDropDownListInsert_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList DropdownDistrict = (DropDownList)DistrictList.InsertItem.FindControl("CityFKDropDownListInsert");
TextBox DistrictTextBox = (TextBox)DistrictList.InsertItem.FindControl("CityFKTextBoxInsert");
DistrictTextBox.Text = DropdownDistrict.SelectedValue;
}
If you want to apply that solution also to EditItemTemplate only thing you have to do changing that line;
DropDownList DropdownDistrict = (DropDownList)DistrictList.InsertItem.FindControl("CityFKDropDownListInsert");
to this;
DropDownList DropdownDistrict = (DropDownList)DistrictList.EditItem.FindControl("CityFKDropDownListInsert");

place the insert part at above the table in listviews

actually i have below listview at my user control page:

could you please guide me how to overcome this problem. i'm using asp.net and c#.
Appreciate your consideration.

I think you need to change your GridView's InsertItemPosition property from InsertItemPosition="LastItem"
to
InsertItemPosition="FirstItem"
in your declaration.

If you want your modal popup to be displayed when the user clicks on the btn_Add_Task button, you should set that button as the TargetControlID of the extender:
<cc1:ModalPopupExtender ID="btn_Add_Task_ModalPopupExtender" runat="server"
TargetControlID="btn_Add_Task" PopupControlID="pnl_Add_Task"
BackgroundCssClass="modalBackground" DropShadow="True" />
In your current code, the modal popup is triggered by a button named Dummy_btn, which I can't find in your markup, but which probably isn't what you want.

We had many issues with ajax popup. you might want to try the approach we have been using for past one month or so with out any issues. This approach creates a popup with out need of ajax / jquery / javascript /css/ update panel .

A modal popup with out using ajax, update panel, jquery or javascript- surprisingly this seems to work
