I have a gridview with three columns admin id, admin name and checkbox, and there is a single button below the gridview,
I want to get the value of admin name column and display it in a label when I check the checkbox and then click the button,
I tried doing this and its working fine but I can get one value only for example if I checked two checkbox and then clicked the button it get only the last value, and I want to get them all.

foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chkRow = (row.Cells[2].FindControl("CheckBox_privileges") as CheckBox);
if (chkRow.Checked)
{
string name= (row.Cells[1].FindControl("label_name") as Label).Text;
Label4.Text = name;
}
}
}
}
In this line you are overriding the text:
Label4.Text = name;
To add all the text you should do something like this:
Label4.Text = name + Label4.Text;

I am trying to calculate the sum of the grand total column and showing it to the footer of the gridview, which I am able to achieve it. However I have a condition which makes some rows invisible from the gridview, but it is also summing the value of the rows which are invisible. How to sum the column value only for the rows which are visible?
Below is my gridview:

I am extracting data from database in gridview, where I have given a link button "Edit" for editing the data of that row. However while editing , one of the columns(YEAR) of my gridview becomes a dropdown list. While fetching the data from database, the Column "Year" consists of label and in edit mode it gets changed to dropdownlist. Moreover I added a condition to make the link buttons appear/disappear based on the value of the Label "Year". When I edit the particular row it throws an error because as soon as edit command is called it converts the column into dropdownlist however the row_databound searches for label. It shows "Object not set to an instance....." PLease help

I am assuming that you are binding your grid with a DataTable with colum name "Year". Try below code where dt refers to your Datatable:
protected void gv1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
int rowno = e.Row.DataItemIndex;
//Suppose dt is DataTable to which you are binding your grid
//and year is the column name within this datatable
string year = Convert.ToString(dt.Rows[e.Row.DataItemIndex]["year"]);
if (year == DateTime.Now.Year.ToString() || year == ((DateTime.Now.Year) - 1).ToString())
{
LinkButton btedt = (LinkButton)e.Row.FindControl("btnedit");
LinkButton btdel = (LinkButton)e.Row.FindControl("btndel");
LinkButton btsm = (LinkButton)e.Row.FindControl("btnmail");
btdel.Visible = true;
btedt.Visible = true;
btsm.Visible = true;
}
if ((e.Row.RowState & DataControlRowState.Edit) > 0)
{
RadioButtonList rbtnlist = (RadioButtonList)e.Row.FindControl("rbtnlist");
DropDownList ddlist = (DropDownList)e.Row.FindControl("ddlyr");
for (int i = (DateTime.Now.Year); i >= ((DateTime.Now.Year) - 1); i--)
{
ddlist.Items.Add(new ListItem(i.ToString(), i.ToString()));
}
ddlist.DataBind();
rbtnlist.DataBind();
}
}
I'm displaying information in a Datagrid not gridView in asp.net. the datagrid contain a column called Status. the status can either be 1 or -1. if the status is 1, i'm displaying a mark icon, then if the status is -1 then displayed a cancel icon. i have done the coding and its working but the problem is, the icons are not showing in all the column depending on the condition as shown in the image below. based on the value in my databasee, the status columns are all -1 but if its showing, its skip on column and bind the next column and so on.

I have a gridview populated with elements extracted from a table in the database. Each row contains 2 textboxes and 1 drop down list. The drop down list is filled when the page is loaded.
My issue is: when I edit the row, select another item from the drop down list and then click on update button, nothing changes. The drop down list still returns to its default value, neither the modiefied values are updated in the db (delete doesn't work etc). I can't understand the reason. Please help me.

I have the following database design:
Employee Table: Username, Name, JobTitle, BadgeNo, IsActive, DivisionCode
Divisions Table: SapCode, DivisionShortcut
And I have a GridView that I am using it to add, delete and update/edit the employees information. This information is employee Username, Name, BadgeNo, JobTitle, IsActive and the DivisionShortcut. IsActive is a flag that indicates if the employee is available or in an assignment. I made it as a checkbox and the column should show two values; Active and Inactive. In the Edit mode, the Checkbox will be displayed. If it is checked, then it means the employee is avaiable, otherwise it is inactive.
I wrote the code and everything works fine, but now I am facing two problems and I don't know how to make them work with my code.
The GridView shows True or False instead of Active and Inactive and
I don't know why.
In the Edit mode, the checkbox will be displayed and the values (Active or Inactive) will be displayed besides to it and it shouldn't be displayed. I just want the checkbox to be displayed.
So how to modify them?

</asp:GridView>
Code-Behind:
//For showing Active or Inactive in the IsActive column instead of True or False
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//Here we will select the IsActive column and modify its text
Label isActive = new Label();
isActive = (Label)e.Row.FindControl("lblIsActive");
//Now, after getting the reference, we can set its text
isActive.Text = "Active or Inactive";
// First check Checkedbox is check or not, if not make it grey
//if (e.Row.Cells[6].Text == "False")
// GridView1.BackColor = Color.Gray;
}
}
And I am getting the following error and I don't know why:
For question no: 1
You have to add an Row_DataBound Event of your grid view, in which you select the IsActive column and replaced its text by Active and InActive. But before going to code behind make a little change to you aspx code: In your item template instead of direct binding place a label control and bind it as I does in the below code:
<asp:TemplateField HeaderText="Is Active?">
<ItemTemplate>
<asp:Label ID="lblIsActive" runat="server" Text='<%# Eval("IsActive") %>' ></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:CheckBox ID="isActive" runat="server"
AutoPostBack="true" OnCheckedChanged="isActive_OnCheckedChanged"
Checked='<%# Convert.ToBoolean(Eval("IsActive")) %>'
Text='<%# Eval("IsActive").ToString().Equals("True") ? " Active " : " Inactive " %>'/>
</EditItemTemplate>
</asp:TemplateField>
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
// here you will select the IsActive column and modify it's text
Label isActive=new Label();
isActive = (Label) e.row.FindControl("lblIsActive");
// after getting the reference set its text
isActive.Text="Active or InActive";
}
}
For question no 2:
Remove the condition form this
Eval("IsActive").ToString().Equals("True") ? " Active " : " Inactive " %>'
and replace it with
Eval("IsActive")
Now check boxes will be displayed.
Updated Answer:
You are receiving an object reference not found error, Please debug your site and check it why you are unable to get the exact reference. I saw you code and it looks that your code is fine.
To prove that my code is working,I created a gridview with a single column
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowDataBound="GridView1_RowDataBound">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("name") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
// and bind this grid view in the Page_Load of my Page
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("name");
DataRow row = dt.NewRow();
row[0] = "Waqar Janjua";
dt.Rows.Add(row);
GridView1.DataSource = dt;
GridView1.DataBind();
}
// When I view this page in the browser it shows "Waqar Janjua"
// Now to update the columns text, I add the following code and it works.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowState != DataControlRowState.Edit)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label l = new Label();
l = (Label)e.Row.FindControl("Label1");
l.Text = "waqar";
}
}
}
// When I run this page now, it shows me "Waqar" not "Waqar Janjua" The code works for me.
It is returning "true" or "false" as it is expecting a boolean data type from IsActive. If you want to change that out put, I suspect you need to amend this conditionally on the ItemDataBound event of the grid.
