Error - Databinding methods such as Eval(), XPath(), and Bind() - c#

I have been getting this error after the submit button has been pressed on my detailsview which has two databound dropdownlists. I do not use Eval or XPath anywhere in my code, but use Bind often.
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

I have been searching this error for days without luck. I already tried WEBSWAPP as well as searched many forums. Please help.
I am trying to use dropdownlists to let a user select values to fill a database. Every field in my form is a template and is databound.

One thing that I notice, which I suspect is just somehow missing from copy and paste is that the first is missing. I don't think it'd compile so I'm guessing that's not existing in your code. However, it's worth checking.
Your error is probably caused by having the SqlDataSource inside the TemplateField. Move those outside of the DetailsView and give it a whirl.

Alter your SqlDataSource directly for DropDownList5
Your error is now probably caused by the SqlDataSource1 trying to access a Label from inside the DetailsView. This can't really happen, so alter the parameter directly.
Change your parameter type
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionStringEvent %>"
ProviderName="<%$ ConnectionStrings:ConnectionStringEvent.ProviderName %>"
SelectCommand="SELECT REASON, LEAVECODE FROM BWLEAVRSN">
<SelectParameters>
<asp:Parameter Name="LEAVECODE" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
Alter the Parameter
protected void DropDownList6_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList lvtype = (DropDownList)(DetailsView1.FindControl("DropDownList6"));
string selectedValue = lvtype.SelectedValue.ToString().ToUpper();
if (selectedValue == "4 " || selectedValue == "1F")
{
DropDownList lvreason = (DropDownList)(DetailsView1.FindControl("DropDownList5"));
SqlDataSource1.SelectParameters["LEAVECODE"].DefaultValue = selectedValue;
lvreason.Visible = true;
}
}

Pass Data from inner grid View to main grid view (gridview in gridview template)ASP.net C#

Am face some troubles to pass data from inner grid to main grid as shown in this pic
im tried too many solution i can found using C# and Jquery
this is simple photo to result
Now this is invoice read from database to show multiple data as shown the grid contain a another grid by normal code it was impossible to access to gridview2 to get data
all i want is get "amount" from gridview2 then calculate "sum" then pass it to "total" in gridview1
also im trid with Jquery it do nothing this is simple code of both fields i want to do sum with Jquery
<script type="text/javascript">
$(function () {
var fields = document.getElementsByClassName('clstocal');
var sum = 0;
for (var i = 0; i < fields.length; ++i) {
var item = fields[i];
sum += parseInt(item.innerHTML);
}
$("#totalprice").text(sum);
}); // this code get it from this site
</script>
<asp:TextBox ID="amount" CssClass ="clstocal" autopostback="true" runat="server" Enabled="False" Height="24px" Text='<%# Bind("body_total") %>' Width="98px" OnTextChanged="amount_TextChanged"></asp:TextBox>
and
<asp:TextBox ID="totalprice" runat="server" Enabled="False" Height="22px" Width="145px" OnTextChanged="totalprice_TextChanged" autopostback="true"></asp:TextBox>
there are a easy solution but not a good solution is sum the result to database then read it again but this is not efficient at all ..
To be honest the answer was simple
1. its impossible to access grid inside grid
2. solved by normal code in C# as shown
protected void GridHead(object sender, GridViewRowEventArgs e)
{
// MAin Grid which is grid number 1
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox textboxPrice1 = e.Row.FindControl("totalprice") as TextBox;
textboxPrice1.Text = i.ToString();
i = 0; // Global double -> protected double i = 0; // THIS LINE TO STOP COUNTING TO OTHER NEXT INVOICE
}
}
protected void GridBody(object sender, GridViewRowEventArgs e)
{
// Inner grid which contain multipe item need to sun then send it to Main grid
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox lblPrice2 = e.Row.FindControl("amount") as TextBox;
i += Convert.ToDouble(lblPrice2.Text);
}
}
and the code behind to handle the grid

Edit on child gridview collapse the expansion

I have a parent grid GVInvoiceDet. CRUD operation on this grid is working fine. In each row of the parent, I have child grid GVTaxDetails which opens on click of image ie expand/collapse feature.
I am looking for CRUD within child grid also. But when I click on edit within child, the texbox for editing doesn't appear and the parent grid collapses.
Here is child grid rowediting code
protected void GVTaxDetails_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView gvTemp = (GridView)sender;
gvUniqueID = gvTemp.UniqueID;
//gvEditIndex = e.NewEditIndex;
gvTemp.EditIndex = e.NewEditIndex;
GVInvoiceDet.DataBind();
}
Parent row editing code
protected void GVInvoiceDet_RowEditing(object sender, GridViewEditEventArgs e)
{
GVInvoiceDet.EditIndex = e.NewEditIndex;
GVInvoiceDet.DataBind();
BindItemGrid();
}

I got the work done... Posting the code for others if come across similar situation.
In parent rowdatabound have added code to keep the div open and update the editIndex.
protected void GVInvoiceDet_RowDataBound(object sender, GridViewRowEventArgs e) {
GridViewRow row = e.Row;
if(row.RowType == DataControlRowType.Header)
{
return;
}
else if (row.RowType == DataControlRowType.DataRow )
{
//Find Child GridView control
GridView gvTax = new GridView();
gvTax = (GridView)row.FindControl("GVTaxDetails");
if (gvTax.UniqueID == gvUniqueID)
{
gvTax.EditIndex = gvEditIndex;
//Expand the Child grid
ClientScript.RegisterStartupScript(GetType(), "Expand", "<SCRIPT LANGUAGE='javascript'>expandcollapse('div" + ((DataRowView)e.Row.DataItem)["itemcd"].ToString() + "','one');</script>");
}
}
}
expandcollapse is function on aspx side:
function expandcollapse(obj, row) {
var div = document.getElementById(obj);
var img = document.getElementById('img' + obj);
if (div.style.display == "none") {
div.style.display = "block";
if (row == 'alt') {
img.src = "Images/minus.png";
}
else {
img.src = "Images/minus.png";
}
img.alt = "Close View Taxes";
}
else {
div.style.display = "none";
if (row == 'alt') {
img.src = "Images/plus.png";
}
else {
img.src = "Images/plus.png";
}
img.alt = "Expand View Taxes";
}
}

Unable to get gridview footer values in RowCommand

I'm creating a page to enter employee's leave details in a dynamic gridview. Entry of data will be done by the from the footer of the gridview. When I try to get the values from the footer, all the text values as well as other values are coming as null or "".
Here is the code of RowCommand:
protected void gvEmployeeDetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("ADD"))
{
TextBox txtAddEmpID = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddEmpID");
RadioButtonList rblFooter = (RadioButtonList)gvEmployeeDetails.FooterRow.FindControl("rblFooter");
TextBox txtAddDoj = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddDoj");
TextBox txtAddLeaves = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddLeaves");
TextBox txtAddDesignation = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddDesignation");
conn.Open();
string cmdstr = "insert into tblLeaves(EmpId,IsActive,DOJ,Leaves,Designation) values(#EmpId,#IsActive,#DOJ,#Leaves,#Designation)";
SqlCommand cmd = new SqlCommand(cmdstr, conn);
cmd.Parameters.AddWithValue("#EmpId", txtAddEmpID.Text);
cmd.Parameters.AddWithValue("#IsActive", rblFooter.SelectedValue);
cmd.Parameters.AddWithValue("#DOJ", txtAddDoj.Text);
cmd.Parameters.AddWithValue("#Leaves", txtAddLeaves.Text);
cmd.Parameters.AddWithValue("#Designation", txtAddDesignation.Text);
cmd.ExecuteNonQuery();
conn.Close();
BindData();
}
}

Please correct me where I'm going wrong.
You are not using sender in your find control code line. Try to replace below line.
TextBox txtAddEmpID = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddEmpID");
this.
protected void gridview_RowCommand(object sender, System.Web.UI.WebControls.GridViewCommandEventArgs e)
{
if (e.CommandName == "Add") {
TextBox txtAddEmpID = (TextBox)((GridView)sender).FooterRow.FindControl("txtAddEmpID");
}
}

While Updating the Rows in grid , I am getting the below error message.
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: >Updating is not supported by ObjectDataSource 'odsShiftDetails' unless the UpdateMethod is >specified.
Guide me how to fix this error. Thanks in advance.
You need to add an update method to your gridview. Look at this tutorial: Gridview ObjectdataSource
