Why would you want to read your HTML tags through code? Are you trying screen scrapping by doing HTML parsing?
In that case you have to identify the starting of an image tag using <img then look for the nearest src tag property and then look for quotes ["]
Is there any other way, yes you have to define a good regular expression to parse for patterns but that would be too much work, but definitely possible and efficient.

Hi, I have an asp.net web application. I have an excel sheet and I have to export that excel sheet to a pdf file. I have done it, but still facing some problems.
1. Whenever I do export, its open excel file. I do not want to open the excel file.
2. I have to convert the pdf file to landscape.
Here is the code
private void ExportExcelToPDF()
{
string sourceFilePath = Server.MapPath("~/aaa.xlsx");
string destinationFilePath = Server.MapPath("~/aaa.pdf");
Microsoft.Office.Interop.Excel.Application myExcelApp;
Microsoft.Office.Interop.Excel.Workbooks myExcelWorkbooks = null;
Microsoft.Office.Interop.Excel.Workbook myExcelWorkbook = null;
try
{
object misValue = System.Reflection.Missing.Value;
myExcelApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
myExcelApp.Visible = true;
object varMissing = Type.Missing;
myExcelWorkbooks = myExcelApp.Workbooks;
if (System.IO.File.Exists(destinationFilePath))
{
System.IO.File.Delete(destinationFilePath);
}
myExcelWorkbook = myExcelWorkbooks.Open(sourceFilePath, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue);
myExcelWorkbook.ExportAsFixedFormat(Microsoft.Office.Interop.Excel.XlFixedFormatType.xlTypePDF,
destinationFilePath, Microsoft.Office.Interop.Excel.XlFixedFormatQuality.xlQualityStandard,
varMissing, false, varMissing, varMissing, false, varMissing);
myExcelWorkbooks.Close();
myExcelApp.Quit();
}
catch
{
}
finally
{
myExcelApp = null;
}
}

I got the solution for this. Actually I did not see that little important thing. 
myExcelApp.Visible = false;
now excel file is not opening.
Now need the solution for the second problem.

Hi all,
I have a Gridview that I populate with values from textboxes. These populated values doesn't have any ID. I can edit and update records but I don't know how to delete records. Please advice on how I can achieve this.
P.S: These records are NOT being saved on the database, only on the Gridview.
I'll appreciate any help I can get.
Thanks.

What is the datastore that you use to populate the gridview. If you can share the logic that you use for edit then we can avoid reinventing the wheel.

I'm using dataTable as staorage and then I save it in a Session. Here is the code.
private void DataBindGrid()
{
try
{
string checkflag;
//Create DataTable.
DataTable dt = (DataTable)Session["dtInfoProfile"];
if (dt == null)
{
//Create DataTable.
dt = new DataTable();
//Assign Columns to it.
dt.Columns.Add(new DataColumn("Full Names"));
dt.Columns.Add(new DataColumn("Type"));
dt.Columns.Add(new DataColumn("Identifying Number"));
dt.Columns.Add(new DataColumn("Passport Number"));
}
//Create a DataRow by dt.NewRow().
DataRow dr = dt.NewRow();
if (rdbIndividual.Checked)
{
//Fill that row and add it to datatable.
checkflag = rdbIndividual.Text;
dr["Full Names"] = IndividualDetailsControl.FirstName + " " + IndividualDetailsControl.LastName;
dr["Type"] = checkflag;
dr["Identifying Number"] = IndividualDetailsControl.IdentityNo;
dr["Passport Number"] = IndividualDetailsControl.PassportNo;
dt.Rows.Add(dr);
}
else if (rdbTrust.Checked)
{
checkflag = rdbTrust.Text;
//Fill that row and add it to datatable.
dr["Full Names"] = EntityDetailsControl.Name;
dr["Type"] = checkflag;
dr["Identifying Number"] = EntityDetailsControl.RegistrationNo;
dt.Rows.Add(dr);
}
else
{
checkflag = rdbEntity.Text;
//Fill that row and add it to datatable.
dr["Full Names"] = EntityDetailsControl.Name;
dr["Type"] = checkflag;
dr["Identifying Number"] = EntityDetailsControl.RegistrationNo;
dt.Rows.Add(dr);
}
Session["dtInfoProfile"] = dt;
//Bind GridView Here with this Table
this.BindData();
//Rename the button
btnAdd.Text = "Add New";
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
}
private void BindData()
{
dgInfoProfile.DataSource = Session["dtInfoProfile"];
dgInfoProfile.DataBind();
}
For Edit and Update:
//Edit
protected void dgInfoProfile_RowEditing(object sender, GridViewEditEventArgs e)
{
//Set the edit index.
dgInfoProfile.EditIndex = e.NewEditIndex;
//Bind data to the GridView control.
this.BindData();
}
//Update
protected void dgInfoProfile_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//Retrieve the table from the session object.
DataTable dt = (DataTable)Session["dtInfoProfile"];
//Update the values.
GridViewRow row = dgInfoProfile.Rows[e.RowIndex];
dt.Rows[row.DataItemIndex]["Full Names"] = ((TextBox)(row.Cells[1].Controls[0])).Text;
dt.Rows[row.DataItemIndex]["Type"] = ((TextBox)(row.Cells[2].Controls[0])).Text;
dt.Rows[row.DataItemIndex]["Identifying Number"] = ((TextBox)(row.Cells[3].Controls[0])).Text;
dt.Rows[row.DataItemIndex]["Passport Number"] = ((TextBox)(row.Cells[4].Controls[0])).Text;
//Reset the edit index.
dgInfoProfile.EditIndex = -1;
//Bind data to the GridView control.
this.BindData();
}

I didn't have the time to experiment, but I think GridViewDeleteEventArgs e is available on the Row Delete event and you can use it to retrieve the row id.
If that is not possible, how about altering the code to add one more value as an identifier and setting the value as the command value for a command button and delete the row corresponding to the command value?
HTH!
|
|
|
|
|
yes, the GridViewDeleteEventArgs e is available but i don't understand where I can get the value of an index, or of an Id if I add another Id column?
|
|
|
|
|
I assume GridViewDeleteEventArgs e has a row index just like the Update event arg. So, you can use it to get the gridview row and use it to get the datatable row just like what you have done for edit.
I've just got these out of the original code that you posted and modified it slightly -
GridViewRow row = dgInfoProfile.Rows[e.RowIndex];
dt.Rows[row.DataItemIndex].Remove();
Try on these lines and I'm sure you must be able to get it to work!

Thanks. There are two event for delete, one is RowDeleting and the other is RowDelete. I tried with RowDeleting. they both don't have Remove() method, thereforre i tried Delete().
GridViewRow row = dgSendFeedbackTo.Rows[e.RowIndex];
dt.Rows[row.DataItemIndex].Delete();
I get the following error when debugging:
"There is no row at position 1."

|

I'm sorry Nopo, I don't have access to VS at this point it time so I cannot help you out on the error message.
But, going by the looks of it try reducing the value of DataItemIndex. May be it might work.

Hi Dinesh,
I've got it right. 
protected void dgSendFeedbackTo_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
DataTable dt = (DataTable)Session["dtFeedback"];
dt.Rows[e.RowIndex].Delete();
this.BindData();
}
Thanks a lot for all your help.

In my aspx page, when I try to debug the application, there are some int variables which shuld give the value in int. However, when i checked the value at the time of debugging, I am getting the values like 0x00002713, 0x000000, 0x00005249 etc. Not sure what this is meant. This is happening very recently.
I didn't change any settings. Any idea what is happening? Even there is a count variable which is also giving the value in above format? I don't know how to fix this? Can anybody please help me on this?
Thanks

The values are being displayed in Hexadecimal format. You might have enabled the 'Hexadecimal Display' for the watch. Rt click on the watch window and uncheck the 'Hexadecimal Display' menuitem.
