I am using a table to display my data in th rdlc report. I am using the "Hide Duplicates" property but that just display blank cells then. Is there any way to get rid of these blank cells.
EXAMPLE.JPG
I have tried to hide it using the visibility expression
iif(Field!SCH.Value="",True,False)
but that doesn't work as the field is not original blank, the values are just hidden as they are duplicates.
I have two tablix in RDLC report,
Tablix2
Tablix3
Tablix2 have 3 rows
Row 1 is used to Show Tablix Header
Row 2 is used to Show Data
Row 3 Containing Tablix3
Here is Design of both Tablixs
My Aim is hidden Tablix3 when there is no data passed to tablix.
Here is Runtime Image without hiding Tablix3
In above Image There is only one detail record for first Purchase no so it will display in RDLC but other purchase No have not details so that will be hidden.
To Hiding Tablix 3 I am using below code in Tablix3 Properties ==> Visibility ==> Show or hide base on an expression Section.
=IIF(IsNothing(Fields!DataColumn9.Value),"False","True")
but when I run RDLC it's giving me Error
the hidden expression for the tablix ‘tablix3’ returned a data type
that is not valid
I also tried
=IIF(Len(Fields!DataColumn9.Value) > 0 ,"True","False")
as well as also changed values "True","False" to 0 and 1, but still same Error
I tried a lot but failed to find out where I am wrong
using this I solved my problem
=IIF(IsNothing(Fields!DataColumn9.Value),True,False)
In visibility Property it needs boolean value and I was passing string values so that was a Error
Following on from an earlier question about dynamic columns in a report viewer, I thought I would at least attempt to get things working.
The output being displayed are columns of mathematical factors, each with their own unique name. These factors (any number from 1 to 10 can be selected) display without issue in my DataGridView control - I generate a DataTable by adding rows/columns as required, and then set the datatable as the Datasource for the DataGridView.
I have added a ReportViewer to my WinForm, and generated a RDLC file. Rather than spend hours trying to figure out how to make it dynamic, my RDLC is set up with 10 columns (as I know there will never be more than this), and the DataSet is assigned to my ReportViewer control. I then use the following code to assign the data to the viewer:
DataTable dt = new DataTable();
var source = this.dgvSelectedElements.DataSource;
while (source is BindingSource)
{
source = ((BindingSource)source).DataSource;
}
var table = source as DataTable;
if (table != null)
{
dt = table;
var reportSource = new ReportDataSource("FactorReport", dt);
this.reportViewer1.Reset();
this.reportViewer1.ProcessingMode = ProcessingMode.Local;
this.reportViewer1.LocalReport.ReportPath = "FactorReport.rdlc";
this.reportViewer1.LocalReport.DataSources.Clear();
this.reportViewer1.LocalReport.DataSources.Add(reportSource);
this.reportViewer1.RefreshReport();
}
So this is how the DataGridview looks:
And then, this is the Reportviewer - note the two 'Rate' and 'Mult' rows appear at the bottom
So whilst it appears to work, I cannot see the values in the grid. Also, when the ages exceed 100, the ages are sorted incorrectly - can sorting be turned off? And on the assumption I can get this to work, is it possible to iterate through the ReportViewer and amend the column captions? A quick google tells me not at run-time?
You should set name of columns in your DataTable which you ceate dynamically as DataSource of DataGridView correctly. They should be Age, Factor1, Factor2, ... , Factor10.
You created the report using those column names. So when you create a DataTable for your grid dynamically, you should set column names same as names you used when creating report.
How can I have same column names?
But you can fix the problem simply by creating a temporary DataTable containing Age, Factor1, ... , Factor10, filled by the original data table. Pass this table to the report and it will work.
How can I have same column titles which is shown in DataGridView?
The solution is column titles as parameters. Create 10 parameters in the report designer and set the title of columns of tablix in report using parameters but don't change name of columns. Those should be Age, Factor1, .... Then when you want to show the report, additional to the temp table which I mentioned above, pass column titles using parameters.
Another Idea
As another idea, you can have the report using exactly the same DataTable which contains all available columns and then when you want to show some columns in report, just pass some parameters to grid which indicates visibility of each column.
Maybe not the best/quickest solution but it works and with some additional changes to the visibility expressions, I'm able to only show the number of columns that have been selected.
I added 10 parameters to my reportviewer named Factor_Name_1 to Factor_Name_10, and checked 'Allow null value' in the properties when creating them. I then wrote some code to add the data for the parameters, storing the existing column names before renaming them to my Factor1, Factor2...Factor10 headings as follows (note I am not worried about in the first 'Age' column):
// loop through the columns to create parameters...
for (int i = 1; i < dt.Columns.Count; i++)
{
// get the name of the column...
string factorName = dt.Columns[i].ColumnName;
// define the new column name...
string colName = string.Format("Factor_Name_{0}", i);
// change the column name now we have stored the real name...
dt.Columns[i].ColumnName = string.Format("Factor{0}", i);
// generate the parameter...
var rparam = new ReportParameter(colName, factorName);
// add it to the parameter set for the control...
this.reportViewer1.LocalReport.SetParameters(new[] { rparam });
}
By re-setting the column names once I've created the associated parameter, the data will then bind correctly. All I had to do then, in my RDLC designer, is to replace the existing headings with the associated parameter values. Then, to hide the columns not selected, I set the visibility expression for the Parameter and Row Textboxes to:
=IIF(ISNOTHING(Parameters!Factor_Name_1.Value),True,False)
....
....
=IIF(ISNOTHING(Parameters!Factor_Name_10.Value),True,False)
Now, if I choose 1 or 10 columns, the viewer displays the correct number of columns and hides those not required. Am now working on repeating the 'age' column (already have the headings repeating) and adding a header/footer at runtime, but I currently have a report that displays the data I need with the correct headings.
Thanks to #Reza Aghaei for getting me on the right track.
I need to show one columns data on multi columns in RDLC report
like
'
Under the properties of the report, you can specify the number of colums desired in the body of the report. This will then allow the data to flow from one column to the next. I used the matrix table, and it worked perfectly.
I am creating a report in telerik reporting. Structure of the report:
Name and day are row and column fields respectively. Now I want to add a row field after the column field. How to do that? I am using Cross Tab control.
