For loop in C#--Very very Urgent

Hello experts,

To give a quick back ground, I have a user control called filters and I am using it around 5 times in my ASPX page. The ids of the controls are filters1,filters2,filters3 etc.

I have few public properties in the user controls. Now I have a function which will return a list of filters as shown below.

Now I am having a for loop which will through an give the values.

Is there a way that, if the Reportfilters.Count=2 it does

filters1.ColumnName = Reportfilters[0].Filter_Column;
filters1.Condition = Reportfilters[0].Condition;
filters1.FilterValue1 = Reportfilters[0].FilterValue1;
filters1.FilterValue2 = Reportfilters[0].FilterValue2;

filters2.ColumnName = Reportfilters[1].Filter_Column;
filters2.Condition = Reportfilters[1].Condition;
filters2.FilterValue1 = Reportfilters[1].FilterValue1;
filters2.FilterValue2 = Reportfilters[1].FilterValue2;

Below is my actual code.

Please help

**********************************************************************************************************
List<ReportFilter> Reportfilters = Controllers.ReportBuilderController.GetAllFilters(Model);

for (int i = 0; i < Reportfilters.Count; i++)
{
filters1.ColumnName = Reportfilters[i].Filter_Column;
filters1.Condition = Reportfilters[i].Condition;
filters1.FilterValue1 = Reportfilters[i].FilterValue1;
filters1.FilterValue2 = Reportfilters[i].FilterValue2;
}

try using FindControl():

filters filter = null;
for (int i = 0; i < Reportfilters.Count; i++)
{
filter = this.FindControl("filters" + i.ToString()) as filter;
if(filter != null)
{
filter.ColumnName = Reportfilters[i].Filter_Column;
filter.Condition = Reportfilters[i].Condition;
filter.FilterValue1 = Reportfilters[i].FilterValue1;
filter.FilterValue2 = Reportfilters[i].FilterValue2;
}
}

As in if the loop value == 2? or just the total count of filters added?
for the 1st option
inside the loop put this:
if(i==2)
{
//do this
}
else
{
//do that
}

Let me know!

swingspen,

I am trying your second option which is feasible for me. But when I try to build the solution I am getting an error saying Not all code paths return a value in this function:

Please help

private Filters GetFiltersControl(int index)
{
switch (index)
{
case 1:
return filters1;

case 2:
return filters2;
}
}

Give this a try

private Filters GetFiltersControl(int index)
{
switch (index)
{
case 1:
return filters1;

case 2:
return filters2;

default:
return null;
}
}

Note: You may want to look at dstanley9's solution as it is essentially doing the same thing as the switch statement above but isn't using a hard coded set of rules. Thus if you add a new filter object in the future as long as you keep with the same naming convention, it'll get picked up.
