column selection of GridView

perreq21-Jan-10 7:56

21-Jan-10 7:56

Hello!
sorry if this has been asked before, couldn't find anything.

I've a gridview populated with data from database.
I want to allow user to click on a column, send the action to the server which will recognize the column selected.

The only actions I can see send the row which was clicked on, and not the column.

For exampel this action:

protected void MainGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
        string s = ((DataRowView)e.Row.DataItem).ToString();
}

Thanks for help!

I know this is not the perfect solution, but you can apply this until you find another one.

Enable Sorting on the gridview and then handle the Sorting event.

inside that you will get a e.SortExpression. which is the Column name you clicked on.

Now call some method by passing it as parameter and return;.

I am not sure but most probably this will work.

thanks for the quick reply
that seems to be a good approach. I tried implement it but it doesn't invoke the action when i click on the grid.
have i forgot something? (I enabled sorting)

all you have to do is, AllowSorting = "true" and then handle the "Sorting" event (OnSorting="GridView1_Sorting"). and then click on the column names (it should be appeared as links) at the run time.

I'm using OWC 11.0 in ASP.NET and C# to create excel file.

I need to protect/unprotect the sheet by a password. I tried to protect the sheet by following code.

string Password = "Password123";
object getPasswordFromUser =(object)Password;
xl.ActiveSheet.Protect(ref getPasswordFromUser, ref obj,
ref obj, ref obj, ref obj, ref obj, ref obj, ref obj, ref obj, ref obj,
ref obj, ref obj, ref obj, ref obj, ref objTrue, ref obj);

But it throws an exception "Exception from HRESULT: 0xE0040059"

Kindly help me to resolve this issue. Code works well if I miss the password.

in this i am following 3 tier architecture from Page i m calling business logic

from UI

<br />
 DataSet ds = myAction.GetOrganizationDetailsPaging(roleId, userId);<br />
        <br />
        //if (reader != null)<br />
        //{<br />
        gridOrganizationDetails.DataSource = ds;<br />
        gridOrganizationDetails.DataBind();<br />

in second layer

if (roleId == Convert.ToInt32(UserRole.Admin))
          {
              query = "Select * from organization";
          }
          else
          {
              query = "select * from organization orga , user us where (orga.pk =us.org_fk) and us.role_fk ='" + roleId + "'" + "and (us.pk ='" + userId + "')";

          }



          DbAction dbConnector = new DbAction();
          //MySqlDataReader reader = dbConnector.ExecuteReader(query);
          DataSet ds = new DataSet();
          ds = dbConnector.ExecuteDataSet(query);
          return ds;

from 3 layer i am returning the following thing

public DataSet ExecuteDataSet(String query)
       {
           DataSet ds = new DataSet();
           MySqlDataAdapter adapter = new MySqlDataAdapter(query, ConfigurationManager.ConnectionStrings["ConnectionString"].ToString());
           adapter.Fill(ds);

           return ds;
       }

Because you forgot to handle PageIndexChanging event of Grid View.

On that event you need to assign new page index to the gridview and then you need to bind the data set again.

i.e.

protected void gridOrganizationDetails_PageIndexChanging(object sender, GridViewPageEventArgs e)
{

gridOrganizationDetails.PageIndex = e.NewPageIndex;

//and then do databinding again.

ds = //set the ds here...;

gridOrganizationDetails.DataSource = ds;
gridOrganizationDetails.DataBind();
}

Dynamically Changing EventHandlers in Web page

moon_stick21-Jan-10 3:13

I've already posted this on StackOverflow[^] but haven't seen much traffic yet...

I've got a web form (set in a master page) and want to check to see if the page has any changes before exiting (either by success or redirect). If any changes have been made, a dialog is displayed and the user can click ok or cancel.

I've created a panel to act as a dialog box (change z-layer, and apply shading and opacity to background) but my problem is in handling the click events from the buttons on the dialog. For a given exit scenario, I want to do something like:

protected void btnWelcomePage_Click(object sender, ImageClickEventArgs e)
{
    if (this.HasChanges())
    {
        lblDialogTitle.Text = "Confirm Exit";
        lblDialogMessage.Text = "Are you sure? Click OK to continue and lose any data entered";
        ClearEventHandlers(btnDialogOK);
        btnDialogOK_Click.Click += new EventHandler(btnDialogOK_Click);
        ClearEventHandlers(btDialogCancel);
        btnDialogCancel_Click += new EventHandler(btnDialogCancel_Click);
        pnlDialog.Visible = true;
    }
    else
    {
        Response.Redirect("~/WelcomePage.aspx");
    }
}

where the event handler for the buttons will do the appropriate work to hide the dialog and redirect if required.

My problem is that the EventHandler doesn't appear to bind between postbacks - setting a breakpoint in the Click event handler doesn't do anything; the page does an empty postback.

I assumed that the postback trashes the EventHandlers so I enabled ViewState on the buttons but to no avail. Can anyone suggest a model for handling this type of change? I've been searching through google but everything appears to relate to the dynamic creation of controls rather than the dynamic assignment of EventHandlers.

Thanks in advance

Dave

It definitely isn't definatley

to add controls (with eventhandlers) on pageweb you have to add it on page-init.

try this:

protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);
        lblDialogTitle.Text = "Confirm Exit";
        lblDialogMessage.Text = "Are you sure? Click OK to continue and lose any data entered";
        ClearEventHandlers(btnDialogOK);
        btnDialogOK_Click.Click += new EventHandler(btnDialogOK_Click);
        ClearEventHandlers(btDialogCancel);
        btnDialogCancel_Click += new EventHandler(btnDialogCancel_Click);
    }

protected void btnWelcomePage_Click(object sender, ImageClickEventArgs e)
{
    if (this.HasChanges())
    {
    
        pnlDialog.Visible = true;
    }
    else
    {
        Response.Redirect("~/WelcomePage.aspx");
    }
}

good luck

Hi To all forum members,

I have a search button which search records in the form, then I have to call a java script which return some values, on the base of these values I have I Have to populate Grid View.
Actually
when I clicked on search button
I) It hits to database and takes records and
II) These records are passed to java script
III) Then java script returns a value location.

On the base of java script values and code behind search criteria values i Have to populate grid view.
I am using asp.net and c# technology.
How can achieve all three steps by single click of search button.

Even i am unable to populate grid on form refresh from that java script code.

All three steps I have to perform in Single click on Search button.
~~I achieved this but I have to click search button twice.~~
