Solution 1

Instead of this:

rds.Value = kds;

try:

rds.Value = kds.Tables[0];

You need to give table as a source and not dataset.

thanks friend,.
but i already try this. if i put rds.Value = kds.Tables[0];

it throw the old error a data source instance has not been supplied for the data source 'dataset1' . what i do for that.

Sandeep Mewara 9-Apr-11 0:42am

Well,
1. It has to be table.
2. Another error that you say sounds like because of reference of "dataset1" in your report which is not being supplied as the same name here. I would suggest you to look at various article here at CP itslef about report generation at runtime and see how it is done.

Thats the spirit.

oh! i find where the "DataSet1" occur in my project.

1. i add report name Report2.rdlc.
2. in Report2.rdlc i drag one table.
3. then chose the dataset window is open. that head name is dataset properties.
4. in that dataset properties contain name, data source, avaliable dataset. in that name text box contain DataSet1.
5. then i chose the datasource, mcs_kioskDataSet. which was already i created.
6. the avaliable datasets taken dataTable1(which is in the s_kioskDataSet) and fields are autamicaly filed.
7. at last i set all table columns with my records.

pls note that 4th point. in that place the DataSet1 is occur in my project.

i check that, rename this DataSet1 to mcs_kioskDataSet also. then the error is a data source instance has not been supplied for the data source 'mcs_kioskDataSet'.

and i am reading the articles. but i cant find the vs2010 reporting article in wpf;,.. i am searching....

in that dataset properties contain name, data source, avaliable dataset. in that name text box contain DataSet1.
See, I told you that might be the case. Good you figured it out.
